Control Application
The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone
Manager and Excel 10 controllers over the Echelon® LonWorks®E-Bus. The W7761A Remote Input/Output Device can be
connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on the E-Bus or
Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the controllers to use their physical
inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to
average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU
Controller. The W7761A device has 8 Digital Outputs which may be Discrete, Modulating or Floating. For example, this allows
the control of lighting zones, miscellaneous exhaust or ventilation fans, miscellaneous pumps, and can enable freeze
protection. See Fig. 2.

Construction
Controllers
The Excel 10 W7761A RIO Device is available in one model. It contains 4 resistive inputs that can be configured for either
20Kohm NTC or PT3000 sensors, 2 voltage or current inputs, 4 digital inputs and 8 Digital Outputs (Triacs) which may be
Discrete (maintained or momentary), Modulating (PWM) or Floating.
The W7761A consists of a single circuit board that is mounted in a sheet metal subbase and protected by a factory snap-on
cover. The device mounts with two screws (see Fig. 3 or 4). Using DIN rail adapters (see Fig. 5) they can also be snapped onto
standard EN 50 022 35 mm by 7.5 mm (1-3/8 in. by 5/16 in.) DIN rail. DIN rail is available through local suppliers. If using DIN
rail also purchase from Augat Inc. part number 2TK2D DIN rail (adapter) two each for every device (see Fig. 5). Wires are
attached to the screw terminal blocks on both sides of the device. Connection for operator access to the E-Bus is provided by
plugging the SLTA connector cable into the communications jack.
A channel in the cover allows the device status LED to be visible when the cover is in place. There are no field-serviceable
parts on the circuit board and, therefore,
it is intended that the cover never be removed
.
The W7761A can be mounted in any orientation. Ventilation openings were designed into the cover to allow proper heat
dissipation regardless of the mounting orientation. See Fig. 3 and 4.

Performance Specifications
Power:
24 Vac with a minimum of 20 Vac and a maximum of 30 Vac at either 50 or 60 Hz. The W7761A power consumption is 6 VA
maximum at 50 or 60 Hz. The W7761A is a NEC Class 2 rated device. This listing imposes limits on the amount of power the
product can consume or directly control to a total of 100 VA (U.S. only).
The individual Triac outputs incorporate an internal common connection with the input power transformer. The Triacs provide a
switched path from the hot side (R) of the transformer through the load to the common of the transformer. The W7761A Device
design
must
use the same power transformer for any loads connected to that device; see Fig. 19.
Each individual Triac is rated 500mA at 30 Vac maximum. Under all operating conditions, the maximum load/source power
budget for the W7761A Device is 100 VA.

CPU:
Motorola or Toshiba 3150 Neuron processor, containing three eight-bit CPU’s. Each Neuron has a unique 48-bit network
identification number.
Memory Capacity:
64K ROM/PROM (6K reserved for network operations, 58K usable for control algorithm code).
512 bytes EEPROM.
2K RAM.
Specified Space Temperature Sensing Range:
45 to 99°F (7 to 37°C) with an allowable control setpoint range from 50 to 90°F (10 to 32°C) when initiated from the network
and 55 to 85°F (13 to 29°C) when configured and connected to T7770 Wall Modules or T7780 DDWM.
Communications:
The W7761A Device uses a transformer-coupled communications port with differential Manchester-encoded data at 78 kilobits
per second (kbs). The transformer-coupled communications interface offers a much higher degree of common-mode noise
rejection while ensuring dc isolation.
Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated
unshielded, twisted pair, solid conductor wire. For non-plenum areas, use Level IV 22 AWG (0.34 mm2) such as U.S. part
AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm2) such as
U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). (See Tables 6 and 8 for part numbers.) Contact Echelon Corp.
Technical Support for the recommended vendors of Echelon approved cables.
The Free Topology Transceiver (FTT) supports polarity insensitive free topology wiring. This frees the system installer from the
need to wire using a bus topology. Star, bus, mixed, and loop wiring are all supported by this architecture. The maximum E-Bus
length when using a combination of star, loop, and bus wiring (singly terminated) is 1640 ft (500m) with the maximum node-to-
node length of 1312 ft (400m). In the event that the total wire length is exceeded, then a Q7740A 2-Way Repeater or a Q7740B
4-Way Repeater can be used to allow the number of devices to be spread out as well as increasing the length of wire over
which they communicate. The maximum number of repeaters per segment is one (on either side of the router). A Q7751A E-
Bus Router can also be used to effectively double the maximum E-Bus length. The advantage of using the router is that it will
segregate traffic to a segment while when using the repeater, all traffic is repeated on each segment. When utilizing a doubly
terminated E-Bus structure, use a continuous daisy-chain with no stubs or taps from the main backbone, The maximum E-Bus
length is 4593 ft (1400m) with the maximum node-to-node length of 3773 ft (1150m).
FTT networks are very flexible and convenient to install and maintain, but it is imperative to carefully plan the network layout
and create and maintain accurate documentation. Unknown or inaccurate wire run lengths, node-to-node distances, node
counts, total wire length, and misplaced or missing terminators can cause poor network performance. Refer to E-Bus Wiring
Guidelines form, 74-2865 for complete description of network topology rules.

When any device is energized by a Triac, the device must be able to sink a minimum of 25 mA.
NOTE: Triacs sink current to the 24 Vac common (COM terminal on the W7761A); see Fig. 19 for wiring example.
IMPORTANT:
If non-Honeywell motors, actuators, or transducers are to be used with Excel 10 Controllers, Triac compatibility must
be verified (see previous NOTE).

Configurations
Each W7761A device can control or monitor a variety of different types of mechanical equipment. The W7761A was not
intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system fan/heat pump units.
The W7761A contains inputs and outputs, but no control software. All control that would be associated with the inputs and
outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control,
temperature control, or any control function that would require less than a 30 second update rate.
It would be suitable to control miscellaneous exhaust or ventilation fans, lighting zones that are spread out through a building
which need to be linked to a start/stop time program through the Zone Manager or to enable freeze protection. The W7761A
device can be connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on
the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The W7761A can be used to monitor
Occupancy, Window, Dirty filter, Indoor air quality, and Smoke control sensors. This allows the controllers to use their physical
inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
16 74-2699
average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU
Controller.
Mixed-Output-Type Control
The W7761A Device can control mixed-output-types of applications such as PWM and staged control occurring simultaneously
with Series 60 Floating Control.
Occupancy Sensor
Excel 10 W7761A device can be connected to an occupancy sensor through a digital input. This is a device, such as a passive
infrared motion detector, that contains a dry contact (see following NOTE) closure to indicate whether or not people are present
in the space. The Excel 10 W7761A Device expects a contact closure to indicate the space is Occupied. See Fig. 18 in
Application Step 4, Prepare Wiring Diagrams, for details on wiring connections. This occupancy sensor can then be bound to
other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This
would allow the other Excel 10 controllers to use their physical inputs for monitoring other elements such as return humidity,
IAQ, etc. to achieve better control.
NOTE: The Excel 10 Controllers (W7750 CVAHU and W7761A RIO) have limited power available (only 9 mA at 4.8 volts) for
checking the digital inputs for contact closures. It is very important that the device used contains high quality,
noncorroding contacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as
gold or silver), pimpled or sealed contacts to assure consistent, long-term operation.
The recommended devices for use with the Excel 10 W7750 Controller and W7761A Device are the EL7628A1007 Ceiling
Mounted Infrared or the EL7680A1008 Wall Mounted Wide View Infrared Occupancy Sensors. If ultrasonic sensors are
required, the EL7611A1003 and the EL7612A1001 Occupancy Sensors are recommended. An EL76XX Power Supply/Control
Unit is required for use with these occupancy sensors. The EL7630A1003 can power up to four sensors, and is multi-tapped for
several line voltages. The EL7621A1002 can power three sensors and it connects to 120 Vac line voltage. The EL7621A1010
can also power three sensors but it connects to 277 Vac line voltage.
Window Open/Closed Digital Input
Excel 10 W7761A device can be connected to a window sensor to indicate whether a window in the space was opened. The
Excel 10 W7761A device can be connected to a dry contact (see the NOTE for the Occupancy Sensor and Fig. 18 in
Application Step 4. Prepare Wiring Diagrams, for details) or a set of contacts wired in series (for monitoring multiple windows)
to verify that the window(s) are closed. This window(s) sensor can then be bound to other Excel 10 controllers on the E-Bus or
Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The algorithm in the other Excel 10 controllers
expects a contact closure to indicate the window is closed. If an open window is detected, the algorithm in the other Excel 10
controllers changes the mode of operation to FREEZE_PROTECT, which shuts down the control functions, and watches for
low space temperature conditions. The freeze protection setpoint is 46.4°F (8°C), and the frost alarm occurs at 42.8°F (6°C).
Wall Module Options
As previously discussed, there are five basic varieties of the T7770. There is one variety of the PT3000 sensor and the T7780
DDWM (see the Product Names and the Construction sections). The T7770A,B,C,D 20Kohm NTC sensor—(current feature
that can be used with the RIO Device) and one PT3000 sensor can be configured on any of the four resistive inputs. The
T7780 is an E-Bus node and would not be directly connected to the RIO Device.
Dirty Filter Monitor
The air filter in the air handler can be monitored by the W7761A RIO device and an alarm issued by the Zone Manager when
the filter media needs replacement. The two methods of monitoring the filter are:
1. Connecting a differential pressure switch to a digital input on the W7761A.
2. Wiring a 2-to-10V differential pressure sensor to a voltage input on the W7761A. If the analog input sensor is used, its
measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint. The comparison is done in the
Zone Manager —valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued when the pressure drop
across the filter exceeds the setpoint.
Indoor Air Quality (IAQ)
The Excel 10 W7761A device can monitor IAQ using one of two different methods of detecting poor air quality. The first is with
an IAQ switch device connected to a digital input on the W7761A, where a contact closure indicates poor air quality, and an
alarm can be issued by the Zone Manager. The device can detect poor air quality using any desired measure such as CO2,
VOC, CO, etc. The second method, is through an analog input that connects to a CO2 sensor (0 to 10V). The measured value
of CO2 from this sensor (0 to 2000 ppm) is compared to a user-selectable setpoint (the comparison is done in the Zone
Manager —valid range: 0 to 2000 ppm), and an IAQ alarm can be issued when the CO2 level exceeds the setpoint. The IAQ
sensor that is connected to the W7750 RIO, can be bound to other W7750 CVAHU Excel 10 controllers on the E-Bus.

APPLICATION STEPS
Overview
The seven application steps shown in Table 3 are planning considerations for engineering an Excel 10 W7761 Remote
Input/Output Device. These steps are guidelines intended to aid understanding of the product I/O options, bus arrangement
choices and the Excel 10 W7761A Devices role in the overall EXCEL 5000® System architecture.
Table 3 . Application Steps.
Step No. Description
1 Plan The System
2 Determine Other Bus Devices Required
3 Lay Out Communication and Power Wiring
4 Prepare Wiring Diagrams
5 Order Equipment
6 Configure Devices
7 Troubleshooting
Step 1. Plan The System
Plan the use of the W7761A Devices according to the job requirements. Determine the location, functionality and sensor or
actuator usage. Verify the sales estimate of the number of W7761A Devices and the number and type of output actuators and
other required accessories.
When planning the system layout, consider potential expansion possibilities to allow for future growth. Planning is very
important to be prepared for adding HVAC systems and controllers in future projects.
T7770A,B,C,D Wall Modules (sensor—current feature that can be used with the RIO Device)can be installed as either
hardwired I/O-only devices or additional wiring can be run to them (for the E-Bus network ) to allow a CARE/E-Vision operator
terminal to have access to the E-Bus. The application engineer needs to determine how many wall modules or other input
sensors are required. This information is required during installation to ensure that the proper number and type of wires are
pulled to the wall modules, and the building operators are informed about where they can plug in to the E-Bus network with a
portable operator terminal (see Fig. 8 through 10).
Fig. 8. Connecting the portable operator terminal to the E-Bus.
The FTT communication loop, (E-Bus) between controllers is a free topology wiring scheme that supports star, loop, and/or bus
wiring. Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules. See Application
Step 3. Lay Out Communications and Power Wiring, for more information on bus wiring layout, and see Fig. 16 through 19 in
Application Step 4. Prepare Wiring Diagrams, for wiring details.
The application engineer must review the Direct Digital Control (DDC) job requirements. This includes the Sequences of
Operation for the Excel 10 controllers, and for the system as a whole. Usually there are variables that must be passed between
the W7750 (CVAHU), Q7750A Zone Manager, W7761 (RIO), and other Excel 10 controller(s), or central plant controller(s) that
are required for optimum system-wide operation. Typical examples are the TOD Occ/Unocc signal, the outdoor air
temperature, demand limit control signal, and smoke control mode signal.
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
18 74-2699
It is important to understand these interrelationships early in the job engineering process to ensure implementing when
configuring the controllers. (See Application Step 6. Configure Devices, for information on the various Excel 10 parameters and
on Excel 10 point mapping.)
Step 2. Determine Other Bus Devices Required
A maximum of 62 nodes can communicate on a single E-Bus segment. Each W7761A (RIO), W7750 (CVAHU), W7751 (VAV)
Controller or T7780 Wall Module constitutes one node. If more nodes are required, a Q7751A Router is necessary. Using a
router allows up to 125 nodes, divided between two E-Bus segments. The router accounts for two of these nodes (one node on
each side of the router); a Q7750A Excel 10 Zone Manager takes one node and two nodes are available for operator terminal
nodes, leaving 120 nodes available for Excel 10 Controllers and T7780 Wall Modules. All 120 controllers and T7780 Wall
Modules are able to talk to each other through the router. A Q7750A Excel 10 Zone Manager is required to connect the E-Bus
to the standard EXCEL 5000® System C-Bus. Each Excel 10 Zone Manager can support no more than 120 Excel 10
Controllers and T7780 Wall Modules. This limit is set in the Excel 10 Zone Manager database as an absolute maximum.
Each E-Bus segment is set up with two unused nodes to allow for a CARE/E-Vision or Hand Held Tool (HHT) to be connected
to the E-Bus. Multiple CARE/E-Vision or HHT terminals can be connected to the bus at the same time. Table 4 summarizes the
E-Bus segment configuration rules.
Table 4 . E-Bus Configuration Rules And Device Node Numbers.
One E-Bus Segment Example Maximum Number of Nodes Equals 62
One Q7750A Excel 10 Zone Manager 1 node
Port for operator terminal access (CARE/E-Vision or HHT) 1 node
Maximum number of Excel 10s and T7780s 60 nodes (Only T7780 Wall Modules are E-Bus nodes)
Total 62 nodes
Two E-Bus Segments Example Maximum Number of Nodes Equals 125
One Q7750A Excel 10 Zone Manager 1 node
One Q7751A Router 2 nodes (1 in each Bus Segment)
Ports for operator terminal access (two CARE/E-Vision or HHT
terminals) 2 nodes (1 in each Bus Segment)
Maximum number of Excel 10s and T7780s in segment number
one 60 nodes (Only T7780 Wall Modules are E-Bus nodes)
Maximum number of Excel 10s and T7780s in segment number
two 60 nodes (Only T7780 Wall Modules are E-Bus nodes)
Total 125 nodes
Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules and the maximum wire
length limitations. If longer runs are required, a Q7740A 2-way or Q7740B 4-way repeater can be added to extend the length of
the E-Bus. A Q7751A Router can be added to partition the system into two segments and effectively double the length of the
E-Bus. Only one router is allowed with each Excel 10 Zone Manager and each network segment can have a maximum of 1
repeater. In addition, all E-Bus segments require the installation of a Bus Termination Module for a singly terminated E-Bus or
two Bus Termination Modules for a doubly terminated E-Bus. For more details on E-Bus termination, refer to the E-Bus Wiring
Guidelines form, 74-2865, or see Application Step 3. Lay Out Communications and Power Wiring, and the E-Bus Termination
Module subsection in Application Step 4.
Step 3. Lay Out Communications and Power Wiring
E-Bus Layout
The communications bus, E-Bus, is a 78-kilobit serial link that uses transformer isolation and differential Manchester encoding.
Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated
unshielded, twisted pair, solid conductor wire. For nonplenum areas, use Level IV 22 AWG (0.34 mm2), such as U.S. part
AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm2) such as
U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). See Tables 9 and 10 for part numbers. Contact Echelon Corp.
Technical Support for the recommended vendors of Echelon approved cables. The FTT communications bus, E-Bus,
supports a polarity insensitive, free topology wiring scheme that supports star, loop, and/or bus wiring.
E-Bus networks can be configured in a variety of ways, so refer to the E-Bus Wiring Guidelines form, 74-2865 for a complete
description of network topology rules and Table 4. Fig. 9 and 10 depict two typical E-Bus network topologies; one as a singly
terminated bus segment that has 60 nodes or less, and one showing a doubly terminated segment. The bus configuration is
set up using the Network Manager tool from within CARE (see the CARE User’s Manual form, 74-5587 or Excel E-Vision
User’s Guide form, 74-2588).

NOTE: For wiring details see the E-Bus Termination Module subsection in Step 4. For wall module wiring, US part AK3782
(non-plenum) or US part AK3792 (plenum) can be used. These cables contain two twisted pairs (one for the run down
to the wall module, and one for the run back up to the controller) for ease of installation.

Notes on communications wiring:
All field wiring must conform to local codes and ordinances.
Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm
2
) plenum or non-plenum
rated unshielded, twisted pair, solid conductor wire. For nonplenum areas, use Level IV 22 AWG (0.34 mm
2
), such
as U.S. part AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22
AWG (0.34 mm
2
) such as U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). See Tables 9 and 10 for part
numbers. Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved
cables.
Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.
Do not use different wire types or gauges on the same E-Bus segment. The step change in line impedance
characteristics causes unpredictable reflections on the bus. When using different types is unavoidable, use a
Q7751A Router at the junction.
In noisy (high EMI) environments, avoid wire runs parallel to noisy power cables, or lines containing lighting
dimmer switches, and keep at least 3 in. (76 mm) of separation between noisy lines and the E-Bus cable.
Make sure that neither of the E-Bus wires is grounded.
Power Wiring
A power budget must be calculated for each Excel 10 W7761 Device to determine the required transformer size for proper
operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled
by an Excel 10 W7761 Device. This includes the device itself, the equipment actuators (ML6161, or other motors) and various
contactors and transducers, as appropriate, for the Excel 10 configuration.
Power Budget Calculation Example
The following is an example power budget calculation for a typical W7761A Excel 10 Device.

The Excel 10 System example requires 29.9 VA of peak power; therefore, a 40 VA AT72D Transformer is able to provide
ample power for this device and its accessories. Alternatively, a 75 VA AT88A Transformer could be used to power two Excel
10 Systems of this type, or a 100 VA AT92A Transformer could be used to power three of these controllers and meet NEC
Class 2 restrictions (no greater than 100 VA). See Fig. 12 through 14 for illustrations of power wiring details. See Table 5 for
VA ratings of various devices. Table 5 . VA Ratings For Transformer Sizing.

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power
budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized
outputs and calculate the VA ratings accordingly. The worst case, that uses the largest possible VA load, should be determined
when sizing the transformer.
Line Loss
Excel 10 Controllers must receive a minimum supply voltage of 20 Vac. If long power or output wire runs are required, a
voltage drop due to Ohms Law (I x R) line loss must be considered. This line loss can result in a significant increase in total
power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft (61m)
run from the transformer to a W7761 Device drawing 37 VA using 18 AWG (1.0 mm2) wire.
The formula is:
Loss = [length of round-trip wire run (ft)] x [resistance in wire (ohms per ft)] x [current in wire (amperes)]
From specification data:
18 AWG twisted pair wire has 6.52 ohms per 1000 feet.
Loss = [(200 ft) x (2 - round-trip) x (6.52/1000 ohms per ft)] x [(37 VA)/(24V)] = 4.02 volts
This means that four volts are going to be lost between the transformer and the device; therefore, to assure the device receives
at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the
size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load. Fig. 11 shows this
voltage load dependence.
In the preceding I x R loss example, even though the device load is only 37 VA, a standard 40 VA transformer is not sufficient
due to the line loss. From Fig. 11, a 40 VA transformer is just under 100 percent loaded (for the 37 VA device) and, therefore,
has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 11 that represents the worst case
conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the device, which is not enough voltage for
proper operation.
In this situation, the engineer basically has three alternatives:
1. Use a larger transformer; for example, if an 80 VA model is used, see Fig. 11, an output of 24.4 volts minus the four volt
line loss supplies 20.4V to the device. Although acceptable, the four-volt line-loss in this example is higher than
recommended. See the following
IMPORTANT
.
2. Use heavier gauge wire for the power run. 14 AWG (2.0 mm2) wire has a resistance of 2.57 ohms per 1000 ft which,
using the preceding formula, gives a line-loss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA
transformer to be used. 14 AWG (2.0 mm2) wire is the recommended wire size for 24 Vac wiring.
3. Locate the transformer closer to the device, thereby reducing the length of the wire run, and the line loss.
The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula
and method are used. The rule to remember is to keep all power and output wire runs as short as practical. When necessary,
use heavier gauge wire, a bigger transformer, or install the transformer closer to the device.
IMPORTANT
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
22 74-2699
No installation should be designed where the line loss is greater than two volts to allow for nominal operation if the
primary voltage drops to 102 Vac (120 Vac minus 15 percent).
To meet the National Electrical Manufacturers Association (NEMA) standards, a transformer must stay within the NEMA limits.
The chart in Fig. 11 shows the required limits at various loads.
With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a
purchased transformer meets the NEMA standard DC20-1986, the transformer voltage-regulating ability can be considered
reliable. Compliance with the NEMA standard is voluntary.
The following Honeywell transformers meet this NEMA standard:

IMPORTANT
Notes on power wiring:
All field wiring must conform to local codes and ordinances.
To maintain NEC Class 2 and UL ratings, the installation must use transformers of 100 VA or less capacity.
For multiple controllers operating from a single transformer, the same side of the transformer secondary must be
connected to the same input terminal in each device and the ground terminals (1 on the W7761A) must be
connected to a verified earth ground for each device in the group. See Fig. 13. (Device configurations are not
necessarily limited to three devices per transformer.)
For the W7761A Device (which has Triac outputs), all output devices must be powered from the same transformer
as the one powering the Excel 10 W7761A Device.
Use the heaviest gauge wire available, up to 14 AWG (2.0 mm
2
) with a minimum of 18 AWG (1.0 mm
2
) for all
power and earth ground connections.
To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the E-Bus
communications loop.
Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
24 74-2699
Make earth ground connections with the shortest possible wire run using 14 AWG (2.0 mm
2
) wire. A good earth
ground is essential for W7761A operation. Ideally, connect the earth ground to the ground bus at a motor control
center or circuit breaker panel. However, if the nearest ideal earth ground is inaccessible, consider an alternate
source for earth ground. Metal water pipe is generally a good ground, but do not use sprinkler pipe if prohibited by
local codes. Attention must be given when duct work, conduit, or rebar are to be considered as ground sources. It
is the responsibility of the installer to assure that these structures are tied back to a known earth ground.
Step 4. Prepare Wiring Diagrams
General Considerations
The purpose of this step is to assist the application engineer in developing job drawings to meet job specifications. Wiring
details are included for the W7761A device the T7770A,B,C,D wall module (sensor—current feature that can be used with the
RIO Device) and the T7780 DDWM. The drawings detail I/O, power, and communication bus wiring connections.
NOTE: For field wiring, when two or more wires are to be attached to the same connector block terminal, be sure to twist
them together. Deviation from this rule can result in improper electrical contact. See Fig. 15.
The connector block terminals on the W7761A and on the T7770 accept 14 through 22 AWG (2.0 to 0.34 mm2) wire. Table 6
lists wiring types, sizes, and length restrictions for Excel 10 products.

provided by plugging the connector into the communications jack.
NOTE: If an Excel 10 W7761A Device or Zone Manager is not connected to a good earth ground, the device internal transient
protection circuitry is compromised and the function of protecting the device from noise and power line spikes cannot
be fulfilled. This can result in a damaged circuit board and require replacing the device.

Alarms
When an Excel 10 has an alarm condition, it reports it to the central node on the E-Bus (typically, the Excel 10 Zone Manager).
See Table 9. Information contained in an alarm message is:
Subnet Number:
E-Bus subnet that contains the Excel 10 node that has the alarm condition. Subnet 1 is on the Zone Manager side of the
router; Subnet 2 is on the other side.
Node Number:
Excel 10 node that has the alarm condition (see Network Status).
Alarm Type:
Specific alarm being issued. An Excel 10 can provide the alarm types listed in Table 9.

See note 1 below.
SENSOR_FAILURE 3 One or more sensors have failed.
NOTE: The node can be reset by switching the node to MANUAL and then to the normal operating mode.
Also, the Excel 10 variables,
AlarmLogX
where
X
is 1 through 5, that store the last five alarms to occur in the device, are
available. These points can be viewed through XBS or E-Vision.
Broadcasting the Service Message
The Service Message allows a device on the E-Bus to be positively identified. The Service Message contains the device ID
number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building.
There are two methods of broadcasting the Service Message from an Excel 10 W7761A Device. One uses a hardware service
pin button on the side of the device (see Fig. 24). The other involves using the PC Configuration tool, as follows.
The commissioning tool is used to perform the ID Assignment task (see the E-Vision User’s Guide form, 74-2588).

APPENDICES
Appendix A. Using E-Vision to Commission a W7761 Device.
CARE/E-Vision must be used to configure the W7761 device. The inputs and outputs will be configured through the application
selection menu (see E-Vision user guide form, 74-2588). The RIO does not contain control loops for directly controlling the
digital outputs, therefore the Zone Manager or some other device has to be bound to the outputs to perform the control
function. Refer to the CARE User’s Manual form, 74-5587 to add Control Strategy, Switching Logic, or Time Programs for
control of the RIO digital outputs. Refer to the E-Vision user guide (form, 74-2588 for the RIO commissioning procedure and
updating/downloading of the Zone Manager files.
NOTE: The RIO device does not synchronize the floating digital outputs. This function (position is synchronized whenever an
endpoint is reached (full open or full close).and when the elapsed time since the last synchronization is 24 hours)
must be done by the controlling device (such as the Zone Manager).
SENSOR CALIBRATION
The resistive temperature sensors and
voltage/current
inputs can all be calibrated. The wall module setpoint potentiometer
is
not supported on the W7761A.
Perform the sensor calibration by adding an offset value (either positive or negative) to the
sensed value using E-Vision menus (see E-Vision user guide form, 74-2588).
When calibrating voltage/current sensors on the W7761A, the offset amount entered by the user is in volts, regardless of the
inputs actual engineering units. See Appendix E for information on how to derive the proper voltage value to enter as an offset
during calibration.
CUSTOM MAPPING
The RIO default CARE plant contains all available points that are supported on the RIO device. If the RIO plant was
customized by deleting unused points, then the Custom mapping feature will have to be used to add points back into the plant
so that they can be used or monitored by other devices. The following procedures will describe the Custom mapping process
for adding analog/digital inputs and digital outputs.
ADDING ANALOG INPUTS - ENTHALPY (4 to 20 mA)
To add an enthalpy (outdoor or return air) sensor to an RIO plant, the user must add a software point (pseudo analog) that can
be mapped to the actual hardware input through the Custom Mapping function of E-Vision. The following procedure will instruct
the user on adding the pseudo analog and using the Custom Mapping function. This allows the enthalpy input to be used with
other Excel 10 controllers (referenced) on the E-Bus, used in Zone Manager control strategy or switching logic, or be used with
Excel 5000 controllers on the C-Bus.
1. With CARE running, open an existing RIO plant. The user can go into either switching logic or control strategy to add the
pseudo analog point. If the user does not have an existing control loop through control strategy, use switching logic to
add the pseudo point, otherwise a control loop will have to be created along with unnecessary RACL to add the point.
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
40 74-2699
This procedure will use switching logic to add the pseudo analog point. With the RIO plant having the focus, go into
switching logic. Select the
Software Points
menu item and then
Pseudo Analog
. The
Create/Select Software Point
<
Va
>
dialog box will be displayed. Type in a New point name for the enthalpy sensor (such as

also added to the
Point List
. Select the
Cancel
button to exit the
Create/Select Software Point
<
Va
> dialog box. Exit
switching logic by selecting the
File
menu item and
Exit
. CARE will display the
Delete Unused Software Points
list box.
Click the
Cancel
button to continue.
2. Go into the
Data Point Editor
(
Controller/Edit/Data Point Editor
) and under
Point
select the pseudo analog point that was
just created and click the
OK
button. Select the drop down list for the
Engineering Unit
and scroll through the list until the
mA (mA matches the engineering unit of the RIO input) engineering units are displayed. Select the mA engineering unit
that is shown with one decimal place (number 66) and click the
OK
button to save the selection. Cancel the
User
Address
list box and select
File/Exit
to exit out of the Data Point Editor.
3. Translate the Zone Manager and Export the Zone Manager files to E-Vision by selecting the
Project
and
Export to E-
Vision
menu items. Type in the name of the Zone Manager Export file when the
Export Zone Manager
dialog box is
displayed. Select the project and the Zone manager within that project that is being exported and click the

button.
Exit CARE and Start E-Vision. Select the E-Vision project to open and the CARE Export Filename created above. Once
the project is open, select the RIO device that the enthalpy sensor is connected to and go into the
Application Selection
screen (offline) by selecting the
Controller
, then the
Application Selection
menu items. From the
Inputs
tab of the
Application Selection
dialog box, add Oa_Enthalpy to either analog input 5 or 6 and select the
OK
button to save the
selection.
4. Select the

from CARE to import the Zone Manager files with the new pseudo
analog point. If this function has already been performed before, the user will be prompted with the message CARE
Export File has already been imported, do you want to import again?. Select
Yes
to continue with the Import. When the
import is finished, E-Vision displays the message CARE Export File has been imported. Select
OK
to continue.

Common Operations
The Excel 10 W7761A Device contains inputs and outputs, but no control software. All control that would be associated with
the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for
VAV control, temperature control, or any control function that would require less than a 30 second update rate. The analog and
digital sensors could be shared or bound to other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus
through the Excel 10 Zone Manager. This would allow the other Excel 10 controllers to use their physical inputs for monitoring
other elements such as return humidity, IAQ, etc. to achieve better control.
Room Temperature Sensor (RmTemp)
EXCEL 10 W7761A INPUT/OUTPUT DEVICE
43 74-2699
The T7770A,B,C,D wall module is the room space temperature sensor—(current feature that can be used with the RIO
Device). When it is configured, it provides the temperature input that can be shared with the W7750 or W7751 controllers. If
there are multiple space sensors in a area controlled by one W7750 CVAHU, then the space temperatures can be wired into
the W7761A controller and mapped to the Zone Manager. The Zone Manager can average all of the space temperatures and
then have that value can be bound to the W7750 controlling that area.
Window Sensor (StatusWndw)
The digital input for a window contact can be wired into the W7761A device and then bound to a W7750 CVAHU to disable its
temperature control algorithm if someone has opened a window or door in the room or area that the W7750 is serving. When a
window is detected to be Open (digital input contacts Open equals window open), the normal temperature control is disabled,
and the W7750 Controller enters the Freeze Protect mode. Freeze Protect mode sets the space setpoint to 50 °F (10°C) and
brings on the fan and heat if the space temperature falls below this setpoint. Normal temperature control resumes on window
closure.
Dirty Filter Monitor
The air filter in the air handler can be monitored by a digital input in the W7761A and an alarm issued by the Zone Manager
when the filter media needs replacement. The two methods of monitoring the filter are:
1. A differential pressure switch whose contacts are connected to a digital input on the W7761A and;
2. A 2 to 10V differential pressure sensor wired to a voltage input on the W7761A. If the analog input sensor is used, its
measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint in the Zone Manager, the
comparison is done in the Zone Manager - valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued by
the Zone Manager when the pressure drop across the filter exceeds the setpoint.
Series 60 Modulating Control
Series 60 Control is also commonly referred to as Floating Control. The Excel 10 W7761A Device can drive Series 60 type
actuators to control a modulating damper or valve actuator. The W7761A device contains no control software, so these outputs
would have to be bound to either the Zone Manager or other Excel 10 controllers. When floating control is used, the full-stroke
motor drive time of the actuator must be entered into the configuration parameter DO1FlSpeed (for output 1), DO2FlSpeed (for
output 2). When Floating control is configured, two digital outputs are required, so the user has to change the configuration
parameter for the appropriate digital outputs.
Pulse Width Modulating (PWM) Control
The Excel 10 W7761A device can drive a PWM-type actuator to control a modulating actuator. The W7761A device contains
no control software, so these outputs would have to be bound to either the Zone Manager or other Excel 10 controllers. PWM
control positions the actuator based on the length, in seconds, of the pulse from the digital output. The controller outputs a
pulse whose length consists of two parts, a minimum and a maximum. The minimum pulse time represents the analog value of
zero percent (also indicates a signal presence) and the maximum pulse length that represents an analog value of 100 percent.
If the analog value is greater than zero percent, an additional time is added to the minimum pulse time. The length of time
added is directly proportional to the magnitude of the analog value. If PWM control is used, the configuration parameters for
the PWM operation must be specified. These parameters are DO1PWMPeriod and PWMZeroScale, and PWMFullScale.
Example: To find the pulse width of a valve actuator (for example stroke mid position - 50 percent) with the PWMZeroScale =
0.1 seconds, PWMFullScale = 25.5 seconds, and the PWMPeriod = 25.6 seconds. There are 256 increments available, so the
number of increments required for 50 percent would be (0.5 X 256) or 128. The time for each increment for this industry
standard pulse time is 0.1 seconds. The pulse width is the minimum time (0.1 second) + the number of increments (128 times
the seconds added 0.1) = 12.9 seconds. The W7750B Controller would command the valve output on for 12.9 seconds every
25.6 seconds to maintain the valve position at 50 percent.
Indoor Air Quality (IAQ) Override
The Excel 10 W7761A Device can monitor an IAQ sensor and that input can be bound to a W7750 CVAHU Controller that
supports an IAQ override feature, that upon detection of poor air quality in the space, allows the economizer dampers to be
opened above the standard minimum position setting to a value set in EconIAQPos (parameter located in W7750). Two
different methods of detecting poor air quality are supported, The first is by using an IAQ switch device connected to a digital
input on the W7761A Device, where a contact closure indicates poor air quality. This digital input would then be bound to the
W7750 Controller that is serving the area being monitored and would initiate the IAQ override mode. The second is through an
analog input that connects to a CO2 Sensor (0 to 10V). The measured value of CO2 from this sensor (0 to 2000 ppm) is
mapped into the Zone Manager where it is compared to a setpoint (parameter located in the Zone Manager). When the CO2
level is higher than the setpoint, the Zone Manager can initiate an IAQ alarm. A pseudo digital point in the Zone Manager can
be bound to the W7750 CVAHU Controller which can initiate the IAQ override mode.

nviInUse is used by a management node to indicate to all other management
nodes that it is logged on, to the Excel 10 node and that they should not try to
interact with any of the Excel 10s network variables. Before the management node
reads or writes any network variables, the management node checks nviInUse for
a zero value meaning no other management nodes are already logged on and that
a management node may log on, to the node. Then the management node writes a
number, 1 through 65534, to nviInUse and periodically writes the same value to
indicate that the management node is still logged on. If there are no writes made to
nviInUse for approximately 60 seconds, then the Excel 10 resets nviInUse to zero
to automatically log off the management node. Before interacting with any network
variables, the management node verifies that the nviInUse has not changed. The
management node logs off by writing 0 to nviInUse.
During power up, an application restart, or return to on-line from off-line, the Excel
10 sets nviInUse to 65535 to indicate to the management node that it has returned
to on-line.

AlarmSubnet: is the LonWorks subnet number (in domain entry 1 of the nodes
domain table) to which the node is assigned.
AlarmType: is the alarm type being issued. When an alarm condition is no longer
TRUE, type is set to the sum of the alarm conditions numeric value and the
RETURN_TO_NORMAL numeric value. The type also is recorded in
AlarmTypeLog0 through AlarmTypeLog4. When a new alarm is detected, just the
corresponding numeric value for the alarm is reported. Refer to table 9 (Excel 10
Alarms) in the System Engineering Guide for all the error conditions that may be
reported.
X M AlarmTypeLog0 (0, 1, 2, 3, 129, 130, 131, 255)
A supervisory node may poll the AlarmTypeLog output for a short alarm history. The
last five alarm reports sent via nvoAlarm are reported via AlarmTypeLog. When
ALARM_NOTIFY_DISABLED is entered into the log, further alarms or return to
normals are not entered into the log, until alarm reporting is again enabled. If
nvoAlarm is bound and not being acknowledged, the last alarm report entered into
the AlarmTypeLog is the one that was not acknowledged.
See nvoAlarm and for related subjects.
type ( n ) specifies the alarm that was issued via nvoAlarm. See nvoAlarm for the
alarm types used in AlarmTypeLog. The newest alarm is reported in type( 0 ) and
the oldest is reported in type( 4 ). When a new entry is made to the log, the oldest
entry is lost.

Refer to the description for AlarmTypeLog0.
X M ResSensor1Error(AI1): The nvoError is a polled output containing a list of the current
errors detected by the node. A search for error conditions in the node is made
periodically. A diagnostic tool may poll nvoError for all of the current errors. nvoError
uses one bit for each possible error condition. nvoError contains all the detected
current errors even though they may be suppressed for reporting by nvoAlarm.
There is a correspondence between the error conditions and alarm types. nvoError
includes sensor failure errors and input network variable failure detect errors. Any
sensor failure errors result in a SENSOR_FAILURE alarm. Failure to receive any
bound network variable periodically results in an INPUT_NV_FAILURE alarm.
nvoError tells which sensor(s) or network variable(s) have failed. See nvoAlarm,
AlarmTypeLog for related subjects.

ApplicationType identifies the current application number of the Excel 10.
nciDeviceName is an 18 character field used to identify the node uniquely as one

management node. If nciDeviceName is all ASCII blanks, it is considered
unconfigured.
The time stamp of the last change to the Excel 10 application configuration. Time
meets the ANSI C time stamp requirement specifying the number of seconds
elapsed since midnight (0:00:00), January 1, 1970. It is represented in the Intel
Format.
VersionNumber identifies the version number of the Excel 10 application.
X M X AILowLimit: This is the low limit value or the lowest value that will be displayed for
this sensor. This value must be between the AIOutputRLow and AIOutputRHigh and
lower than the value specified for AIUpperLimit.
X M X AIOutputRHigh: This is the equivalent temperature degrees F (degrees C) value for
the resistance entered for AIResHigh. Using the resistance example for AIResHigh
of 48,000 ohms, you would enter the equivalent temperature of 45.0 degrees F (7.2
degrees C) for the AIOutputRHigh value.
X M X AIOutputRLow: This is the equivalent temperature degrees F (degrees C) value for
the resistance entered for AIResLow. Using the resistance example for AIResLow of
11,520 ohms, you would enter the equivalent temperature of 99.0 degrees F (37.2
degrees C) for the AIOutputRLow value.
X M X AIResHigh: This is the highest resistance value of the user specified range for a
custom resistive input as selected through E-Vision in the input Tab of the
Application selection screen. The user can select between a PT3000
(Custom_PT3000) or a 20 Kohm NTC (Custom_20 Kohm NTC) sensor. This value is
specified in ohms with LSB in 10 Ohms. This means that if your high resistance
value for a 20 Kohm NTC sensor was 48,000 ohms, 45.0 degrees F (7.2 degrees C),
the value that would be entered for AIResHigh would be 4800 (the resistance value
divided by ten).
X M X AIResLow: This is the lowest resistance value of the user specified range for a
custom resistive input as selected through E-Vision in the input Tab of the
Application selection screen. The user can select between a PT3000
(Custom_PT3000) or a 20 Kohm NTC (Custom_20 Kohm NTC) sensor. This value is
specified in ohms with LSB in 10 Ohms. This means that if the low resistance value
for a 20 Kohm NTC sensor was 11,520 ohms, 99.0 degrees F (37.2 degrees C), the
value that would be entered for AIResLow would be 1152 (the resistance value
divided by ten).

X M X AIUpperLimit: This is the high limit value or the highest value that will be displayed
for this sensor. This value must be between the AIOutputRLow and AIOutputRHigh
and higher than the value specified for AILowLimit.
X M P X DeltaC: The default value of delta for all RIO sensor types is set to zero. With this
default value, the RIO will send the sensor values at the fastest rate of 2 seconds
update rate. However, if the user desires to reduce the network traffic or not receive
the noisy sensor values, a delta value can be specified. This value will force the RIO
to transmit the sensor value when the current value exceeds the last sent value by
the delta amount. RIO will also send the sensor value whenever the time of update
exceeds nciRioSendT. RIO will send the sensor value at the rate of nciRioSendT
regardless of delta change.

X M X DO1PWMPeriod is a intermittent voltage pulse whose width varies in proportion to
the desired actuator position. The PWM signal has three parameters that have to be
configured in order for the output to function correctly. The period, is the overall pulse
lenegth in seconds. The percent_time (signal presence) is the zero percent position
of the actuator output. The actuator requires this signal (pulse width) sent once every
period, so that it knows that it is still connected to the controller and where the zero
position starts. The variable width (delta_time) portion is incremented in proportion to
the signal percentage. There are 255 increments available (for example 0.1 second).
Thus, the pulse width will be the minimum width (percent_time) plus the number of
increments (delta_time/ 255). The smallest time that can be used with the RIO
controller is 0.1 second. An example stroke at mid position is: 0.1 second
(percent_time) + 128 x 0.1 (255/0.5 - 50 percent position) = 12.9 seconds. The period
would equal the percent_time plus the delta_time (for example 0.1 seconds) + 255 x
0.1 seconds = 25.6 seconds.

X X M P DestManMode: is an input which is used to manually set the physical outputs.
DestManMode remains unchanged until another mode has been commanded or an
application restart has been performed. The valid enumerated values are:
MODE_ENABLE enables the node so that the RIO controls the physical outputs as
the normal mode. MODE_ENABLE is the default state after power is restored or an
application restart occurs. If the mode was MANUAL and DestManMode is set to
MODE_ENABLE, the node then goes through application restart.
MODE_DISABLED sets the node into the DISABLED mode. The alarm
NODE_DISABLED is initiated, and the physical outputs are turned off. The physical
inputs, network variable inputs, and network variable outputs are still functioning
when the node is in the DISABLED mode.
MODE_MANUAL sets the node into the MANUAL mode. The alarm
NODE_DISABLED is initiated, and the physical outputs are controlled manually as
commanded by DestManMode. The nodes configuration variables and
DestManMode are used to set valves, dampers, and/or digital output to the desired
manual positions or state(s). The physical inputs, network variable inputs, and
network variable outputs are still functioning when the node is in the MANUAL mode.
SUPPRESS_ALARMS causes AlarmType to be set to ALARM_NOTIFY_DISABLED,
and AlarmTypeLog to no longer record alarms. If alarms are suppressed,
UNSUPPRESS_ALARMS causes AlarmType and AlarmTypeLog to be returned to
reporting alarms. See nvoAlarm for more details. All unspecified values are the same
as MODE_ENABLE.

Zone Manager Point Estimating Guide.
Memory size approximation is shown below: (all sizes in bytes)
When
memory size
is less than 110,000 bytes, the size is OK.
When
memory size
is between 110,000 and 128,000 bytes, the application may be too large. The user must expect to reduce
the application complexity, reduce the number of attached Excel 10s or distribute the Excel 10s over more than one Zone
Manager.
When
memory size
is greater than 128,000, the size is too large. The application size must be reduced as described above.
Approximate Memory Size Estimating Procedure.
1. Determine the number of points per controller required at the Central (for example, XBS).
NOTE: All remaining points that are not mapped can be accessed through the
Direct Access
feature.
2. Calculate the number of Excel 10 Zone Manager program points that are used in control logic and in the switching table.
3. Estimate the program complexity of the Zone Manager (one of three levels).
a. No time programs, control logic, or switching tables.
b. 10K of control logic (one time program, five switching tables, and five control loops).
c. 20K of control logic (multiple time programs, ten switching tables, and ten control loops).
Use Fig. D-1 to determine the number of Excel 10s that can be connected to the Zone Manager.
NOTE: More than 60 Excel 10s requires a Router.
4. Repeat for each Q7750A Excel 10 Zone Manager in a project.

The exact equation for calculating memory size follows:
Memory size = 21,780
+ 4096 (in case of a time program).
+ CARE Control Program.
+ 14 x time points x Excel 10 units.
+ 50 x Excel 10 units.
+ map complexity x Excel 10 units x mapped points.
+ 57 x C-Bus points.
+ 7488 x Excel 10 types.
Where:
Time points = number of switch points in time program per Excel 10.
Excel 10 units = number of attached Excel 10s.
C-Bus points = including mapped points and others; for example, remote points.
Mapped points = number of mapped points per Excel 10,
including One-to-Many and Many-to-One
mechanism.
Excel 10 types = number of different Excel 10 types (currently three)
Map complexity =
20 = using One-to-Many and not using
points with read/write.
30 = average.
45 = many points with read/write ability.
