Watlow EZ-ZONE® PM Integrated Controller 2 Chapter 1 Overview
Chapter 1: Overview
1
The EZ-ZONE® PM takes the pain out of solving
your thermal loop requirements.
Watlows EZ -ZONE® PM controllers offer options
to reduce system complexity and the cost of control-
loop ownership. You can order the EZ-ZONE® PM as
a PID controller or an over-under limit controller, or
you can combine both functions in the PM Integrat-
ed Limit Controller. You now have the option to in-
tegrate a high-amperage power controller output, an
over-under limit controller and a high-performance
PID controller all in space-saving, panel-mount
packages. You can also select from a number of se-
rial communications options to help you manage sys-
tem performance.
It just got a whole lot easier to solve the ther-
mal requirements of your system. Because the EZ-
ZONE® PM controllers are highly scalable, you only
pay for what you need. So if you are looking for a
PID controller, an over-under limit controller or an
integrated controller, the EZ-ZONE® PM is the an-
swer.

Watlow EZ-ZONE® PM Integrated Controller 3 Chapter 1 Overview
A Conceptual View of the PM
The flexibility of the PM’s software and hardware al-
lows a large range of configurations. Acquiring a bet-
ter understanding of the controller’s overall function-
ality and capabilities while at the same time plan-
ning out how the controller can be used will deliver
maximum effectiveness in your application.
It is useful to think of the controller in three
parts: inputs; procedures; and outputs. Information
flows from an input to a procedure to an output when
the controller is properly configured. A single PM
controller can carry out several procedures at the
same time, for instance closed-loop control, monitor-
ing for several different alarm situations and oper-
ating switched devices, such as lights and motors.
Each process needs to be thought out carefully and
the controllers inputs, procedures and outputs set up
properly.
Inputs
The inputs provide the information that any given
programmed procedure can act upon. In a simple
form, this information may come from an operator
pushing a button or as part of a more complex pro-
cedure it may represent a remote set point being re-
ceived from another controller.
Each analog input typically uses a thermocouple
or RTD to read the temperature of something. It can
also read volts, current or resistance, allowing it to
use various devices to read humidity, air pressure,
operator inputs and others values. The settings in
the Analog Input Menu (Setup Page) for each analog
input must be configured to match the device con-
nected to that input.
Each digital input reads whether a device is active
or inactive. A PM with digital input-output hardware
includes two sets of terminals each of which can be
used as either an input or an output. Each pair of
terminals must be configured to function as either
an input or output with the Direction parameter in
the Digital Input/Output Menu (Setup Page).
The Function or EZ Key on the front panel of the
PM also operates as a digital input by toggling the
function assigned to it in the Digital Input Function
parameter in the Function Key Menu (Setup Page).
Functions
Functions use input signals to calculate a value. A
function may be as simple as reading a digital input
to set a state to true or false, or reading a tempera-
ture to set an alarm state to on or off. Or, it could
compare the temperature of a process to the set point
and calculate the optimal power for a heater.
To set up a function, its important to tell it what
source, or instance, to use. For example, an alarm
may be set to respond to either analog input 1 or 2
(instance 1 or 2, respectively).
Keep in mind that a function is a user-pro-
grammed internal process that does not execute any
action outside of the controller. To have any effect
outside of the controller, an output must be config-
ured to respond to a function.
Outputs
Outputs can perform various functions or actions in
response to information provided by a function, such
as operating a heater; turning a light on or off; un-
locking a door; or turning on a buzzer.
Assign an output to a Function in the Output
Menu or Digital Input/Output Menu. Then select
which instance of that function will drive the select-
ed output. For example, you might assign an output
to respond to alarm 4 (instance 4) or to retransmit
the value of analog input 2 (instance 2).
You can assign more than one output to respond
to a single instance of a function. For example, alarm
2 could be used to trigger a light connected to output
1 and a siren connected to digital output 5.
Input Events and Output Events
Input events are internal states that are set by the
digital inputs. Digital input 5 provides the state of
input event 1, and digital input 6 provides the state
of input event 2. Wait for Event steps in profiles
are triggered by these events. The setting of Digital
Input Function (Setup Page, Digital Input/Output
Menu) does not change the relationship between the
input and the event, so take care not to configure the
function in a way that would conflict with a profile
that uses an input event. An input will still control
the input event state, even if Digital Input Function
is set to None.
Output events are internal states that can only be
set by profile steps. Outputs 1 through 4 can be con-
figured to respond to output events.

Installation
case
retention collar
panel
bezel
gasket
1. Make the panel cutout using the mounting tem-
plate dimensions in this chapter.
Insert the case assembly into the panel cutout.
2. While pressing the case assembly firmly against
the panel, slide the mounting collar over the back
of the controller.
If the installation does not require a NEMA 4X
seal, slide the mounting collar up to the back of
the panel tight enough to eliminate the spacing
between the gasket and the panel.
Slide the mounting collar over
the back of the controller.
Place the blade of a screw-
driver in the notch of the
mounting collar assembly.
3. For a NEMA 4X (UL50, IP66) seal, place the
blade of a screwdriver in the notch of the mount-
ing collar assembly and push toward the panel
while applying pressure to the face of the control-
ler. Don't be afraid to apply enough pressure to
properly install the controller. The seal system is
compressed more by mating the mounting collar
tighter to the front panel (see pictures above). If
you can move the case assembly back and forth
in the cutout, you do not have a proper seal.
The tabs on each side of the mounting collar have
teeth that latch into the ridges on the sides of the
controller. Each tooth is staggered at a different
depth from the front so that only one of the tabs,
on each side, is locked onto the ridges at a time.
Note: There is a graduated measurement difference between
the upper and lower half of the display to the panel. In order to
meet the seal requirements mentioned above, ensure that the
distance from the front of the top half of the display to the panel
is 16 mm (0.630 in.) or less, and the distance from the front of
the bottom half and the panel is 13.3 mm (0.525 in.) or less.
Removing the Mounted Controller from Its Case
1. From the controller's face, pull out the tab on
each side until you hear it click.
Pull out the tab on each side
until you hear it click.
Grab the unit above and below
the face and pull forward.
2. Once the sides are released, grab the unit above
and below the face with two hands and pull the
unit out.
If it is difficult to pull the unit out, remove the
connectors from the back of the controller. This
should make it easier to remove.

Returning the Controller to its Case
1. Ensure that the orientation of the controller is
correct and slide it back into the housing.
Note: The controller is keyed so if it feels that it will not
slide back in do not force it. Check the orientation again
and reinsert after correcting.
2. Using your thumbs push on either side of the con-
troller until both latches click.

Default Home Page
The Home Page is a customized list of as many as 20
parameters that can be configured and changed in
the Custom Menu [ CUSt] (Factory Page). The default
list of nine parameters below includes the Active
Process Value (value in upper display) and Active Set
Point (value in lower display). The Attention [Attn]
parameter appears only if there is an active message.
An active message could be a reported error, for ex-
ample, [C;Er1] (Current Error), or it could be for in-
formation only, for example, [tUN1] (Autotuning).
Use the Advance Key to step through the other
parameters. The parameter prompt will appear in
the lower display, and the parameter value will ap-
pear in the upper display. You can use the Up ¿ and
Down ¯ keys to change the value of read-write pa-
rameters, just as you would in any other menu.
If Control Mode is set to Auto, the process value
is in the upper display and the Closed Loop Set Point
(read-write) is in the lower display.
If a profile is running, the process value is in the
upper display and the Target Set Point (read only) is
in the lower display.
If Control Mode is set to Manual, the process val-
ue is in the upper display and the output power level
(read-write) is in the lower display.
If Control Mode is set to Off, the process value is
in the upper display and [`oFF] (read only) is in the
lower display.
If a sensor failure has occurred, [----] is in the
upper display and the output power level (read-write)
is in the lower display.
Changing the Set Point
You can change the set point by using the Up ¿ and
Down ¯ keys, when a profile is not running.
If the set point is displayed and the % indicator is
lit, the controller is in open-loop (manual) mode.
Note: Avoid continuous writes within loops. Excessive writes to
EEPROM will cause premature EEPROM failure. The EEPROM is
rated for 1,000,000 writes.

From any point press and hold the Infinity Key
ˆ for two seconds to return to the Home Page.
Note: Changes made to profile parameters in the Profiling
Pages will be saved and will also have an immediate impact
on the running profile.
Some parameters in the Profile Status Menu can be changed
for the currently running profile, but should only be changed
by knowledgeable personnel and with caution. Changing pa-
rameters via the Profile Status Menu will not change the stored
profile but will have an immediate impact on the profile that is
running.
How to Start a Profile
After defining the profile follow the steps below to
run the profile:
1. From the Home Page push the Advance Key
repeatedly until Profile Start [P;St1] appears in
the lower display.
2. Use the Up ¿ or Down ¯ key to choose the file
or step number within a profile where you want
the profile to begin running.
3. Press the Advance Key . This takes you to
Profile Action [P;AC1], where you can select the
appropriate action.
[none] No action
[ProF] Begin execution from first step of the
specified profile number, whether it exists or not.
[PAUS] Pause the currently running profile.
[rESU] Resume running the profile from the
previously paused step.
[`End] End the profile.
[StEP] Begin running the profile from the spec-
ified step number.
Note: Avoid continuous writes within loops. Excessive writes to
EEPROM will cause premature EEPROM failure. The EEPROM
is rated for 1,000,000 writes.

Watlow EZ-ZONE® PM Integrated Controller 54 Chapter 9 Features
Saving and Restoring User Settings
Recording setup and operations parameter settings
for future reference is very important. If you uninten-
tionally change these, you will need to program the
correct settings back into the controller to return the
equipment to operational condition.
After you program the controller and verify
proper operation, use User Save Set [USr;S] (Fac-
tory Page, Diagnostics Menu) to save the settings
into either of two files in a special section of memory.
If the settings in the controller are altered and you
want to return the controller to the saved values, use
User Restore Set [USr;r] (Factory Page, Diagnostics
Menu) to recall one of the saved settings.
A digital input or the Function Key can also be
configured to restore parameters.
Note: Only perform the above procedure when you are sure that
all the correct settings are programmed into the controller. Sav-
ing the settings overwrites any previously saved collection of
settings. Be sure to document all the controller settings.
Programming the Home Page
Watlow’s patented user-defined menu system im-
proves operational efficiency. The user-defined Home
Page provides you with a shortcut to monitor or
change the parameter values that you use most of-
ten.
You can create your own Home Page with as
many as 20 of the active parameters. When a param-
eter normally located in the Setup Page or Opera-
tions Page is placed in the Home Page, it is acces-
sible through both. If you change a parameter in the
Home Page, it is automatically changed in its origi-
nal page. If you change a parameter in its original
page it is automatically changed in the Home Page.
The default parameters will automatically appear
in the Home Page.
Change the list of parameters in the Home Page
from the Custom Menu [CUSt] (Factory Page).
Tuning the PID Parameters
Autotuning
When an autotune is performed on the EZ-ZONE®
PM, the set point is used to calculate the tuning set
point.
For example, if the active set point is 200° and
Autotune Set Point [A;tSP] (Operations Page, Loop
Menu) is set to 90 percent, the autotune function
utilizes 180° for tuning. This is also how autotun-
ing works in previous Watlow Winona controllers. In
addition, changing the active set point in previous
controllers causes the autotune function to restart;
where with the EZ-ZONE® PM changing the set
point after an autotune has been started has no af-
fect.
A new feature in EZ-ZONE® PM products will al-
low set point changes while the control is autotun-
ing, this includes while running a profile or ramping.
When the auto tune is initially started it will use
the current set point and will disregard all set point
changes until the tuning process is complete. Once
complete, the controller will then use the new set
point.
This is why it is a good idea to enter the active set
point before initiating an autotune.
Autotuning calculates the optimum heating and/
or cooling PID parameter settings based on the sys-
tem's response. Autotuning can be enabled whether
or not TUNE-TUNE+™ is enabled. The PID settings
generated by the autotune will be used until the au-
totune feature is rerun, the PID values are manually
adjusted or TRU-TUNE+® is enabled.
To initiate an autotune, set Autotune Request
[`AUt] (Operations Page, Loop Menu) to [`YES].
You should not autotune while a profile is running. If
the autotune cannot be completed in 60 minutes, the
autotune will time-out and the original settings will
take effect.
The lower display will flash between [tUnE] and
the set point while the autotuning is underway. The
temperature must cross the Autotune Set Point five
times to complete the autotuning process. Once com-
plete, the controller controls at the normal set point,
using the new parameters.
Select a set point for the tune with Autotune Set
Point. The Autotune Set Point is expressed as a per-
cent of the Closed Loop Set Point.
If you need to adjust the tuning procedure's ag-
gressiveness, use Autotune Aggressiveness [T;Agr]
(Setup Page, Loop Menu). Select under damped [Un-
dr] to bring the process value to the set point quick-
ly. Select over damped [ouer] to bring the process
value to the set point with minimal overshoot. Select
critical damped [Crit] to balance a rapid response
with minimal overshoot.

Manual Tuning
In some applications, the autotune process may not
provide PID parameters for the process characteris-
tics you desire. If that is the case, you may want to
tune the controller manually.
1. Apply power to the controller and establish a set
point typically used in your process.
2. Go to the Operations Page, Loop Menu, and set
Heat Proportional Band [`h;Pb] and/or Cool Pro-
portional Band [`C;Pb] to 5. Set Time Integral
[``ti] to 0. Set Time Derivative [``td] to 0.
3. When the system stabilizes, watch the process
value. If it fluctuates, increase the Heat Propor-
tional Band or Cool Proportional Band value in 3
to 5° increments until it stabilizes, allowing time
for the system to settle between adjustments.
4. When the process has stabilized, watch Heat
Power [`h;Pr] or Cool Power [`C;Pr] (Operations
Page, Monitor Menu). It should be stable ±2%. At
this point, the process temperature should also
be stable, but it will have stabilized before reach-
ing the set point. The difference between the set
point and actual process value can be eliminated
with Integral.
5. Start with an Integral value of 6,000 and allow
10 minutes for the process temperature to reach
the set point. If it has not, reduce the setting by
half and wait another 10 minutes. Continue re-
ducing the setting by half every 10 minutes until
the process value equals the set point. If the pro-
cess becomes unstable, the Integral value is too
small. Increase the value until the process stabi-
lizes.
6. Increase Derivative to 0.1. Then increase the set
point by 11° to 17°C. Monitor the systems ap-
proach to the set point. If the process value over-
shoots the set point, increase Derivative to 0.2.
Increase the set point by 11° to 17°C and watch
the approach to the new set point. If you increase
Derivative too much, the approach to the set
point will be very sluggish. Repeat as necessary
until the system rises to the new set point with-
out overshoot or sluggishness.
For additional information about autotune and PID
control, see related features in this chapter.
Autotuning with TRU-TUNE+®
The TRU-TUNE+® adaptive algorithm will optimize
the controller's PID values to improve control of dy-
namic processes. TRU-TUNE+® monitors the process
variable and adjusts the control parameters auto-
matically to keep your process at set point during set
point and load changes. When the controller is in the
adaptive control mode, it determines the appropriate
output signal and, over time, adjusts control param-
eters to optimize responsiveness and stability. The
TRU-TUNE+® feature does not function for on-off
control.
The preferred and quickest method for tuning a
loop is to establish initial control settings and contin-
ue with the adaptive mode to fine tune the settings.
Setting a controller's control mode to tune starts
this two-step tuning process. (See Autotuning in this
chapter.) This predictive tune determines initial,
rough settings for the PID parameters. Then the loop
automatically switches to the adaptive mode which
fine tunes the PID parameters.
Once the process variable has been at set point for
a suitable period (about 30 minutes for a fast process
to roughly two hours for a slower process) and if no
further tuning of the PID parameters is desired or
needed, TRU-TUNE+™ may be turned off. However,
keeping the controller in the adaptive mode allows it
to automatically adjust to load changes and compen-
sate for differing control characteristics at various
set points for processes that are not entirely linear.
Once the PID parameters have been set by the
TRU-TUNE+™ adaptive algorithm, the process, if
shut down for any reason, can be restarted in the
adaptive control mode.
Turn TRU-TUNE+ on or off with TRU-TUNE+
Enable [t;tUn] (Setup Page, Loop Menu).
Use TRU-TUNE+™ Band [t;bnd] (Setup Page,
Loop Menu) to set the range above and below the
set point in which adaptive tuning will be active.
Adjust this parameter only in the unlikely event
that the controller is unable to stabilize at the set
point with TRU-TUNE+™ Band set to auto (0). This
may occur with very fast processes. In that case, set
TRU-TUNE+™ Band to a large value, such as 100.
Use TRU-TUNE+™ Gain [`t;gn] (Setup Page,
Loop Menu) to adjust the responsiveness of the adap-
tive tuning calculations. Six settings range from 1,
with the most aggressive response and most poten-
tial overshoot (highest gain), to 6, with the least ag-
gressive response and least potential for overshoot
(lowest gain). The default setting, 3, is recommended
for loops with thermocouple feedback and moderate
response and overshoot potential.
Before Tuning
Before autotuning, the controller hardware must be
installed correctly, and these basic configuration pa-
rameters must be set:
Sensor Type [`SEn] (Setup Page, Analog Input
Menu), and scaling, if required;
Function [``Fn] (Setup Page, Output Menu) and
scaling, if required.
How to Autotune a Loop
1. Enter the desired set point or one that is in the
middle of the expected range of set points that
you want to tune for.
2. Enable TRU-TUNE+®.
Watlow EZ-ZONE® PM Integrated Controller 56 Chapter 9 Features
3. Initiate an autotune. (See Autotuning in this
chapter.)
When autotuning is complete, the PID parameters
should provide good control. As long as the loop is in
the adaptive control mode, TRU-TUNE+® continu-
ously tunes to provide the best possible PID control
for the process.
ç
WARNING! During autotuning, the controller sets the output
to 100 percent and attempts to drive the process variable
toward the set point. Enter a set point and heat and cool
power limits that are within the safe operating limits of your
system.
Inputs
Calibration Offset
Calibration offset allows a device to compensate for
an inaccurate sensor, lead resistance or other factors
that affect the input value. A positive offset increases
the input value, and a negative offset decreases the
input value.
The input offset value can be viewed or changed
with Calibration Offset [`i;CA] (Operations Page,
Analog Input Menu).

Calibration
To calibrate an analog input, you will need to provide
two electrical signals or resistance loads near the ex-
tremes of the range that the application is likely to
utilize. See recommended values below:
Sensor Type Low Source High Source
thermocouple 0.000 mV 50.000 mV
millivolts 0.000 mV 50.000 mV
volts 0.000V 10.000V
milliamps 0.000 mA 20.000 mA
100 Ω RTD 50.00 Ω 350.00 Ω
1,000 Ω RTD 500.00 Ω 3,500.00 Ω
Follow these steps for a thermocouple or pro-
cess input:
1. Apply the low source signal to the input you are
calibrating. Measure the signal to ensure it is ac-
curate.
2. Read the value of Electrical Measurement [`Mu]
(Factory Page, Calibration Menu) for that input.
3. Calculate the offset value by subtracting this val-
ue from the low source signal.
4. Set Electrical Input Offset [ELi;o] (Factory Page,
Calibration Menu) for this input to the offset val-
ue.
5. Check the Electrical Measurement to see whether
it now matches the signal. If it doesn’t match, ad-
just Electrical Offset again.
6. Apply the high source signal to the input. Mea-
sure the signal to ensure it is accurate.
7. Read the value of Electrical Measurement for
that input.
8. Calculate the gain value by dividing the low
source signal by this value.
9. Set Electrical Slope [ELi;S] (Factory Page, Cali-
bration Menu) for this input to the calculated
gain value.
10. Check the Electrical Measurement to see wheth-
er it now matches the signal. If it doesn’t match,
adjust Electrical Slope again.
Set Electrical Offset to 0 and Electrical Slope to 1 to
restore factory calibration.
Follow these steps for an RTD input:
1. Measure the low source resistance to ensure it
is accurate. Connect the low source resistance to
the input you are calibrating.
2. Read the value of Electrical Measurement [`Mu]
(Factory Page, Calibration Menu) for that input.
3. Calculate the offset value by subtracting this val-
ue from the low source resistance.
4. Set Electrical Input Offset [ELi;o] (Factory Page,
Calibration Menu) for this input to the offset val-
ue.
5. Check the Electrical Measurement to see whether
it now matches the resistance. If it doesn’t match,
adjust Electrical Offset again.
6. Measure the high source resistance to ensure it
is accurate. Connect the high source resistance to
the input.
7. Read the value of Electrical Measurement for
that input.
8. Calculate the gain value by dividing the low
source signal by this value.
9. Set Electrical Slope [ELi;S] (Factory Page, Cali-
bration Menu) for this input to the calculated
gain value.
10. Check the Electrical Measurement to see wheth-
er it now matches the signal. If it doesn’t match,
adjust Electrical Slope again.

Filter Time Constant
Filtering smoothes an input signal by applying a
first-order filter time constant to the signal. Filter-
ing the displayed value makes it easier to monitor.
Filtering the signal may improve the performance of
PID control in a noisy or very dynamic system.
Adjust the filter time interval with Filter Time
[`FiL] (Setup Page, Analog Input Menu).
Example: With a filter value of 0.5 seconds, if the
process input value instantly changes from 0 to 100
and remained at 100, the display will indicate 100 after
five time constants of the filter value or 2.5 seconds.

Sensor Selection
You need to configure the controller to match the in-
put device, which is normally a thermocouple, RTD or
process transmitter.
Select the sensor type with Sensor Type [`Sen]
(Setup Page, Analog Input Menu).
Sensor Backup
Sensor backup maintains closed-loop control after an
input failure by switching control to input 2.
The sensor backup feature is only available in an
EZ-ZONE® PM Integrated limit or remote set point
controller.
Turn sensor backup on or off with Sensor Backup
Enable [`S;bA] (Setup Page, Analog Input 1).
Set Point Low Limit and High Limit
The controller constrains the set point to a value be-
tween a set point low limit and a set point high limit.
Set the set point limits with Low Set Point
[`L;SP] and High Set Point [`h;SP] (Setup Page,
Loop Menu).
There are two sets of set point low and high lim-
its: one for a closed-loop set point, another for an
open-loop set point.
Set Point Range (must be between Range High and Range Low)
Low Limit of selected functional range
High Limit of selected functional range
Gas Pressure
Range High Range (between High Limit of Sensor and Range Low)
Range Low Range (between Low Limit of Sensor and Range High)
Set Point Low
Set Point High
Scale High and Scale Low
When an analog input is selected as process voltage
or process current input, you must choose the value
of voltage or current to be the low and high ends. For
example, when using a 4 to 20 mA input, the scale
low value would be 4.00 mA and the scale high value
would be 20.00 mA. Commonly used scale ranges are:
0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V.
You can create a scale range representing other
units for special applications. You can reverse scales
from high values to low values for analog input sig-
nals that have a reversed action. For example, if 50
psi causes a 4 mA signal and 10 psi causes a 20 mA
signal.
Scale low and high low values do not have to match
the bounds of the measurement range. These along
with range low and high provide for process scaling
and can include values not measureable by the control-
ler. Regardless of scaling values, the measured value
will be constrained by the electrical measurements of
the hardware.
Select the low and high values with Scale Low
[`S;Lo] and Scale High [`S;hi]. Select the displayed
range with Range Low [`r;Lo] and Range High
[`r;hi] (Setup Page, Analog Input Menu).
Range High and Range Low
With a process input, you must choose a value to rep-
resent the low and high ends of the current or voltage
range. Choosing these values allows the controller’s
display to be scaled into the actual working units of
measurement. For example, the analog input from a
humidity transmitter could represent 0 to 100 per-
cent relative humidity as a process signal of 4 to 20
mA. Low scale would be set to 0 to represent 4 mA
and high scale set to 100 to represent 20 mA. The in-
dication on the display would then represent percent
humidity and range from 0 to 100 percent with an
input of 4 to 20 mA.
Select the low and high values with Range Low
[`r;Lo] and Range High [`r;hi] (Setup Page, Analog
Input Menu).
Receiving a Remote Set Point
The remote set point feature allows the controller
to use a thermocouple, RTD, 1 k potentiometer or
process signal at input 2 to establish the set point,
Watlow EZ-ZONE® PM Integrated Controller 58 Chapter 9 Features
which allows its set point to be manipulated by an
external source. A common application would use one
ramping controller with a set-point retransmit out-
put to ramp multiple controllers using the remote set
point. Or you could use an analog output from a PLC
to send set point values to an EZ-ZONE® PM.
The controller must have two process inputs to
use the remote set point feature.
You may select between local and remote set
points at the front panel, with an event input, from a
remote computer using the communications feature
or from an external switch using an event input.
Make sure all input and output impedances are
compatible.
Switch to the remote set point with Remote En-
able [`r;En] (Operations Page, Loop Menu). Select
whether the remote set point controls an open- or
closed-loop set point with Remote Set Point Type
[`r;ty].
Assign the function of switching to a remote set
point to a digital input with Digital Input Function
[``Fn] (Setup Page, Digital Input Menu).
Assign the function of switching to a remote set
point to the EZ Key with Digital Input Function
[``Fn] (Setup Page, Function Key Menu).
Outputs
Duplex
Certain systems require that a single process output
control both heating and cooling outputs. An EZ-
ZONE® PM controller with a process output can func-
tion as two separate outputs.
With a 4 to 20mA output the heating output will
operate from 12 to 20mA (0 to +100 percent) and the
cooling output will operate from 12 to 4mA (0 to -100
percent).
In some cases this type of output is required by
the device that the EZ-ZONE® PM controls, such as
a three-way valve that opens one way with a 12 to
20mA signal and opens the other way with a 4 to
12mA signal. This feature reduces the overall system
cost by using a single output to act as two outputs.
Outputs 1 and 3 can be ordered as process out-
puts. Select duplex [dUPL] as the Output Function
[``Fn] (Setup Page, Output Menu). Set the output to
volts [uoLt] or milliamps [`MA] with Output Type
[`o;ty]. Set the range of the process output with
Scale Low [`S;Lo] and Scale High [`S;hi].
No-arc Relay
A no-arc relay provides a significant improvement in
the life of the output relay over conventional relays.
Conventional mechanical relays have an expected
life of 100,000 cycles at the rated full-load current.
The shorter life for conventional relays is due to the
fact that when contacts open while current is flowing
metal degradation occurs. This action produces un-
avoidable electrical arcing causing metal to transfer
from one contact to the other. The arcing conditions
continue on each subsequent contact opening until
over time the resistance through the contacts in-
creases causing the contacts to increase in tempera-
ture. Eventually, the contacts will weld together and
the relay remains in the on state.
The Watlow no-arc relay is a hybrid relay. It uses
a mechanical relay for the current load and a triac
(solid-state switch) to carry the turn-on and turn-off
currents. No-arc relays extend the life of the relay
more than two million cycles at the rated full-load
current.
Although a no-arc relay has significant life advan-
tages, a few precautions must be followed for accept-
able usage:
Do not use:
hybrid relays for limit contactors. A limit or
safety device must provide a positive mechanical
break on all hot legs simultaneously;
dc loads with hybrid relays. The triacs used for
arc suppression will turn off only with ac line
voltage;
hybrid switches to drive any inductive loads, such
as relay coils, transformers or solenoids;
cycle times less than five seconds on hybrid
switches;
on loads that exceed 264V ac through relay;
on loads that exceed 15 amperes load;
on loads less than 100 mA;
no-arc relays in series with other no-arc relays.
Retransmitting a Process Value or Set Point
The retransmit feature allows a process output to
provide an analog signal that represents the set
point or process value. The signal may serve as a
remote set point for another controller or as an in-
put for a chart recorder documenting system perfor-
mance over time.
In choosing the type of retransmit signal the op-
erator must take into account the input impedance
of the device to be retransmitted to and the required
signal type, either voltage or milliamps.
Typically applications might use the retransmit
option to record one of the variables with a chart re-
corder or to generate a set point for other controls in
a multi-zone application.
Outputs 1 and 3 can be ordered as process out-
puts. Select retransmit [rMt] as the Output Func-
tion [``Fn] (Setup Page, Output Menu). Set the out-
put to volts [uoLt] or milliamps [`MA] with Output
Type [`o;ty]. Select the signal to retransmit with
Retransmit Source [`r;Sr].

value, the retransmit output will be at its Scale Low
value. When the retransmit source is at the Range
High value, the retransmit output will be at its Scale

Cool Output Curve
A nonlinear output curve may improve performance
when the response of the output device is nonlinear.
If a cool output uses one of the nonlinear curves a
PID calculation yields a lower actual output level
than a linear output would provide.
These output curves are used in plastics extruder
applications: curve 1 for oil-cooled extruders and
curve 2 for water-cooled extruders.

Control Methods
Output Configuration
Each controller output can be configured as a heat
output, a cool output, an alarm output or deactivat-
ed. No dependency limitations have been placed on
the available combinations. The outputs can be con-
figured in any combination. For instance, all three
could be set to cool.
Heat and cool outputs use the set point and Oper-
ations parameters to determine the output value. All
heat and cool outputs use the same set point value.
Heat and cool each have their own set of control pa-
rameters. All heat outputs use the same set of heat
