The generator can operate safely, efficiently and reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed
to the unit are, therefore, not all inclusive. If using a
procedure, work method or operating technique that
the manufacturer does not specifically recommend,
ensure that it is safe for all personnel. Also make sure
the procedure, work method or operating technique
utilized does not render the generator unsafe.


 GENERAL HAZARDS 
• For safety reasons, the manufacuter recommends
that this equipment be installed, serviced and
repaired by an Authorized Service Dealer or other
competent, qualified electrician or installation technician who is familiar with applicable codes, standards and regulations. The operator also must comply with all such codes, standards and regulations.
• Installation, operation, servicing and repair of this
(and related) equipment must always comply with
applicable codes, standards, laws and regulations.
Adhere strictly to local, state and national electrical and building codes. Comply with regulations
the Occupational Safety and Health Administration
(OSHA) has established. Also, ensure that the
generator is installed, operated and serviced in
accordance with the manufacturer’s instructions
and recommendations. Following installation, do
nothing that might render the unit unsafe or in
noncompliance with the aforementioned codes,
standards, laws and regulations.
• The engine exhaust fumes contain carbon monoxide gas, which can be DEADLY. This dangerous gas,
if breathed in sufficient concentrations, can cause
unconsciousness or even death. For that reason,
adequate ventilation must be provided. Exhaust
gases must be piped safely away from any building
or enclosure that houses the generator to an area
where people, animals, etc., will not be harmed.
This exhaust system must be installed properly,
in strict compliance with applicable codes and
standards.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit
is operating.
• Adequate, unobstructed flow of cooling and ventilating air is critical in any room or building housing the generator to prevent buildup of explosive
gases and to ensure correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seriously affect safe operation of the generator.
• Keep the area around the generator clean and
uncluttered. Remove any materials that could
become hazardous.
• When working on this equipment, remain alert
at all times. Never work on the equipment when
physically or mentally fatigued.
Wireless Display System
• Inspect the generator regularly, and promptly
repair or replace all worn, damaged or defective
parts using only factory-approved parts.
• Before performing any maintenance on the generator, disconnect its battery cables to prevent
accidental start-up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
 ELECTRICAL HAZARDS 
• All generators covered by this manual produce
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch,
as does the standby generator. Avoid contact with
bare wires, terminals, connections, etc., on the generator as well as the transfer switch, if applicable.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator. If work
must be done around an operating unit, stand on
an insulated, dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
• If people must stand on metal or concrete while
installing, operating, servicing, adjusting or repairing this equipment, place insulative mats over a
dry wooden platform. Work on the equipment only
while standing on such insulative mats.
• The National Electrical Code (NEC), Article 250
requires the frame and external electrically conductive parts of the generator to be connected to
an approved earth ground and/or grounding rods.
This grounding will help prevent dangerous electrical shock that might be caused by a ground fault
condition in the generator set or by static electricity. Never disconnect the ground wire.
• Wire gauge sizes of electrical wiring, cables and
cord sets must be adequate to handle the maximum electrical current (ampacity) to which they
will be subjected.
• Before installing or servicing this (and related)
equipment, make sure that all power voltage
supplies are positively turned off at their source.
Failure to do so will result in hazardous and possibly fatal electrical shock.
• Connecting this unit to an electrical system normally supplied by an electric utility shall be by
means of a transfer switch so as to isolate the
generator electric system from the electric utility
distribution system when the generator is operating. Failure to isolate the two electric system power
sources from each other by such means, will result
in damage to the generator and may also result
in injury or death to utility power workers due to
backfeed of electrical energy.
• Generators installed with an automatic transfer
switch will crank and start automatically when
normal (UTILITY) source voltage is removed or is
below an acceptable preset level. To prevent such
automatic start-up and possible injury to personnel, disable the generator’s automatic start circuit
(battery cables, etc.) before working on or around
the unit. Then, place a “Do Not Operate” tag on
the generator control panel and on the transfer
switch.
• In case of accident caused by electric shock, immediately shut down the source of electrical power. If
this is not possible, attempt to free the victim from
the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting implement, such as a dry rope or board, to free the
victim from the live conductor. If the victim is
unconscious, apply first aid and get immediate
medical help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.
 FIRE HAZARDS 
• Keep a fire extinguisher near the generator at all
times. Do NOT use any carbon tetra-chloride type
extinguisher. Its fumes are toxic, and the liquid
can deteriorate wiring insulation. Keep the extinguisher properly charged and be familiar with its
use. If there are any questions pertaining to fire
extinguishers, consult the local fire department.
 EXPLOSION HAZARDS 
• Properly ventilate any room or building housing
the generator to prevent build-up of explosive gas.
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.
• These generator sets may operate using one of
several types of fuels. All fuel types are potentially
FLAMMABLE and/or EXPLOSIVE and should be
handled with care. Comply with all laws regulating the storage and handling of fuels. Inspect the
unit’s fuel system frequently and correct any leaks
immediately. Fuel supply lines must be properly installed, purged and leak tested according to
applicable fuel-gas codes before placing this equipment into service.
• Diesel fuels are highly FLAMMABLE. Gaseous
fluids such as natural gas and liquid propane
(LP) gas are extremely EXPLOSIVE. Natural gas
is lighter than air, and LP gas is heavier than air;
install leak detectors accordingly.
Wireless Display System
‹ OPERATION AND MAINTENANCE
The operator is responsible for proper and safe use
of the equipment. The manufacturer strongly recommends that the operator read this Owner's Manual
and thoroughly understand all instructions before
using this equipment. The manufacturer also strongly recommends instructing other users to properly
start and operate the unit. This prepares them if they
need to operate the equipment in an emergency.
It is the operator's responsibility to perform all safety
checks, to make sure that all maintenance for safe
operation is performed promptly, and to have the
equipment checked periodically by an Authorized
Service Dealer. Normal maintenance service and
replacement of parts are the responsibility of the
owner/operator and, as such, are not considered
defects in materials or workmanship within the
terms of the warranty. Individual operating habits
and usage contribute to the need for maintenance
service.
Proper maintenance and care of the generator ensures
a minimum number of problems and keeps operating
expenses at a minimum. See an Authorized Service
Dealer for service aids and accessories.
Operating instructions presented in this manual
assume that the standby electric system has been
installed by an Authorized Service Dealer or other
competent, qualified contractor. Installation of this
equipment is not a “do-it-yourself” project.
‹ HOW TO OBTAIN SERVICE
When the generator requires servicing or repairs,
contact an Authorized Service Dealer for assistance.
Service technicians are factory-trained and are capable of handling all service needs.
When contacting an Authorized Service Dealer about
parts and service, always supply the complete model
number of the unit as given on the front cover of this
manual or on the DATA LABEL affixed to the unit.
INTRODUCTION
The wireless display system consists of two identical
radio transceivers, one mounted near the generator
and the other (the one with the display), should be
in a convenient viewing location. The system has a
“line of sight” range of about 300 feet but this will be
reduced if the signal has to go through walls, etc.. The
display is intended to show the status of the generator and warn you if the system is in an alarm state. It
also provides the following additional functions:
• Permanent time/date stamped history of generator
events such as starting and stopping
• Allowing remote starting and stopping of the generator
• Facility to set an exercise time & day from the display
• Facility to adjust the “bad” utility voltage threshold
• Facility to set up a service schedule
• Ability to add extra displays
• Graphing capability
The unit can be either battery powered or fed from a
separate plug in wall transformer. The History is kept
in permanent memory that is not lost even when all
power is lost. The clock function is kept alive by a
separate, replaceable 10 year life battery.
BATTERY OPERATION
The wireless display can be operated either from a
plug in wall transformer or from three AAA alkaline
batteries. The batteries can be rechargeable but are
NOT recharged from the wall transformer and should
be separately charged. In the case of battery operation, the unit will go to sleep for 60 seconds then
exchange data for up to two (2) seconds to conserve
battery life. The display screen will turn off in the
sleep mode unless there is an alarm to be displayed.
It can be awoken by pressing the ENTER key after
which it will remain awake for one (1) minute if no
further keys are pressed. If the display is operated
continuously on batteries, the expected battery life is
three (3) months when using standard alkaline 1.2Ah
batteries. The batteries are NOT used to retain data
such as the history log or the radio settings, they will
not be lost in the event of a dead battery.
NOTE 1:
In battery sleep mode it will take up to two (2)
minutes to detect if the radio link is lost. This long
delay is to allow for the unit’s sleep time.
NOTE 2:
In battery sleep mode, if the wall transformer is
plugged into the unit, it will take up to one minute
to recognize this fact.
There is a separate battery for the time and date
function. This has an expected life of ten years
after which it can be replaced. To replace the battery, remove the four screws holding on the back
of the case and carefully fold out the circuit board
without disconnecting the display. Remove the large
yellow battery module from the centre of the board
by pulling on the corners. Replace the battery THE
CORRECT WAY ROUND with the spot in the corner
of the battery facing the on/off switch. Replace the circuit board and the back of the case. You will need to
reset the time and date. The GENERAC part number
for the battery is 0A7287G.
Wireless Display System
INSTALLATION
For easier installation, the batteries should first be
fitted into the display unit (Figure 1). This will allow
you to walk around and find the best location for the
unit while still receiving good signal strength. Attach
the other transceiver to the generator and mount it as
high as possible, preferably away from any structures
to get a maximum signal.
Figure 1 — Open Display Unit
1. Insert the batteries (Figure 2).
Figure 2 — Insert Batteries
4. The display will show that it is searching for the
generator and the yellow LED may flash occasionally as it receives data from the generator transceiver. This is due to the unit searching for the
correct channel.
5. Once the generator is found, the radio link is now
setup and the settings will be remembered next
time the display unit is turned on. If the generator is not found, an error message will briefly be
shown, and the yellow LED will flash at one (1)
second intervals to indicate the display unit was
unable to find the generator.
6. If the battery power to the generator (and therefore the end transceiver) is ever disconnected, the
radio link will need to be reset. See the section
titled “Reset Radio”.
7. If the generator is not talking to it’s transceiver,
but the radios are talking to each other, this will
be indicated by an appropriate alarm which will
be displayed after a 30 second period. Check the
wiring and connection to the generator.
8. Place the display at the preferred location. Do not
permanently mount it yet.
9. Plug the wall transformer into the display so as
not to use up the batteries. Familiarize personnel
with the radio menu (by reading the manual in
conjunction with operating the display).
10. Navigate the display to show the “Radio
Information” screen from the radio menu.
11. Monitor the signal strength and relocate the display if the signal strength is poor or non existent.
The signal strength display is only updated if the
unit can communicate, (which occurs every two
(2) seconds), and will be set to display zero if the
unit cannot communicate within a ten (10) second period.
12. Mount the display using the holes on the back to
hang onto two suitably sized fixing screws in the
drywall 2¼ inches apart. It should be vertically
mounted on a wall BETWEEN studs for maximum signal strength (Figure 3).
Figure 3 — Mounting Holes
2. Connect the generator end transceiver and ensure
it is turned on.
3. IMMEDIATELY turn on the display, one minute
will pass while the generator tries to find it’s display.
Wireless Display System
13. Set the time and date into the clock, use the
instructions given in the "Time and Date Menu"
section. The time & date will be remembered
even if the battery goes dead. There is a separate,
replaceable 10 year battery for this function.
14. The communications LED will light solid to show
data is being received. A flashing LED indicates
the unit was unable to find the generator.
15. Set an exercise day and time now (see "Exercise
Menu" section).
‹ BACKLIGHT
THE COMMUNICATIONS LED
The communications LED will light solid to show
data is being received. If the LED flashes at regular
one (1) second intervals, it indicates the unit was
unable to find the generator. Irregular flashing is an
indication of poor reception.
Operation of the display is controlled by three (3)
buttons labeled +, —, and Enter. These buttons are
used to navigate the display to the required page, or
to enter data. The +/— buttons are also referred to
as the arrow keys. Holding down a button for more
than half a second will cause it to autorepeat until it
is released.
GENERATOR COMMUNICATIONS
‹ BATTERY AND SIGNAL STRENGTH INDICATORS
The transceiver requests data from the generator
every two (2) seconds and this is stored inside the
transceiver locally. The data is relayed to the base
station over the radio link every time it is requested
by the display about every two (2) seconds. When
on battery power, the data is only requested every
minute to conserve batteries. If the generator is not
talking to it’s transceiver, but the radios are talking
to each other, this will be indicated by an appropriate alarm which will be displayed after a seven (7)
second period (Figure 4). Check the wiring and connection to the generator.
In the top left corner of the display, there are two
icons (or pictures) that give a quick indication of
the state of the internal battery and the radio signal
strength (Figure 5). The battery is represented by the
left hand, single tall rectangle which is drawn as being
somewhere between full and empty. Full represents
greater than 75% capacity, mostly full represents 5075% capacity, half full represent 25-50% and mostly
empty represents 0-25% capacity. The signal strength
icon is shown to the right of the battery icon as three
vertical bars representing greater than 25%, greater
than 50%, and greater than 75%. Three bars indicate
excellent signal strength, two bars represent good
signal strength (about 45%), one bar represents weak
signal strength. Two bars is the normal indication.

‹ CONTRAST ADJUSTMENT
The display contrast can be adjusted from the
“Settings” menu. Any changes to the contrast setting
will be remembered even if power is removed from
the display.
The display is backlit providing that it is powered
from the wall transformer. If batteries are being
used the backlight is disabled to conserve power.
The backlight is lit whenever a key is pressed. It will
remain lit for 20 seconds if there are no further keypresses. If an alarm occurs, the backlight will flash at
a one (1) second rate (not if battery powered).

The history log is a chronological list of
“events” that have occurred to the generator.
An event is any change in status such as an
alarm, a start or stop, the keyswitch being operated,
etc.. These events are permanently stored inside the
display module along with a time and date stamp
when they occurred. They will not be lost even if the
battery goes dead, but there is the option to erase the

falls below this level, the generator will start. Note
that if the generator battery is ever disconnected or
goes dead, this setting will need to be re-entered.
The range of adjustment is limited by the generator
(for example – a maximum of 170 VAC on air-cooled
units) even though the display allows a larger range.
This is to accommodate different models.
‹ SERVICE SCHEDULE
The display can be set to alarm on a specific date
for an alert that a service is required. The date is
set using the two arrow keys. Setting the month to

Wireless Display System
EXERCISE MENU
‹ CHANGING CHANNELS
Normally the exercise time is set on the generator control board as it powers up. If an
exercise time has not been set on the control
board, all it’s LED’s will flash and an alarm will be set
on the wireless display – “EXERCISE TIME NOT
SET”.
Channel selection is normally automatic, manually
changing channels should only need to be done if
experiencing interference from other equipment. This
can be identified by looking at the signal strength and
the signal quality. If the signal strength is good but
the quality is not, there may be some interference.
Changing channels on the main display will automatically change the channel on the generator end
provided a link has been established. If the “change
channel” message fails for any reason, the units will
revert to their old channel selection. A new channel
setting will be remembered for the next time the unit
is powered up. To change channels on an established
and working link, simply select “Change Channel”
from the Radio menu, then enter a new channel
number.
The exercise page of the wireless display can be used
to overwrite any exercise time set in the generator.
Use the arrow keys and follow the on-screen instructions to set the time and day. The wireless display calculates the difference in time from the exercise date
and time to the current date and time, and downloads this to the generator. This means you MUST set
the correct date and time on the display. The exercise
cycle is repeated at the same time weekly and does
not use the wireless system to do this, all the timing
is in the generator. If you ever remove power from the
generator, you will need to re-set the exercise time
when you re-set the radio (see the reset radio command in the radio menu section).

If the signal strength is poor, re-locate the display to
somewhere with a higher signal strength. Unplug the
wall adapter and walk around while observing the
signal strength. Mount the unit at a point where the
signal strength is at a high level (not necessarily the
highest level). The transceiver at the generator end
can then be relocated. The best position for this is as
high up as possible away from any structures.
If the signal quality is low but the signal strength is
good, there may be some interference. See the section
on "Changing Channels".
Changing the channel number on a link that is not
established is a little more complex, the only reason
this may need to be done is if a link cannot be establish because the default channel is noisy. To perform
this task, follow these instructions:
1. Remove power from the generator end of the link.
Power up the display.
2. Go to the radio menu and select “Reset radio”.
This will try and establish a link but it will fail,
the process will take about one minute.
3. Go to the “Change Channel” menu and select a
new channel.
4. Go back and select the “Reset Radio” command
and immediately turn on the generator end of the
link.
5. The radio link should establish itself on the channel selected. This will be remembered even when
the power is turned off to the display.
If the unit is a secondary display, no checking is done
to ensure the channel matches the current system
channel. Set the channel to the current system channel. Look on the main display and select the radio
menu, then select “Radio Information”. This will tell
you the current channel that is being used.
‹ RESET RADIO
Normally the system will set itself up out of the box,
however if you have to replace either of the transceivers ( the display or the generator end), or if power is
ever lost to the generator end (such as a flat generator battery) you will need to re-train the system and
re-set the exercise time. You will NOT have to re-train
the system if the battery in the display goes flat, the
system will remember the radio settings.
If communications are totally lost for an unexplained
reason, you may want to perform a new radio setup.
1. Carry the display to a point near the generator
and turn it on. Go to the radio menu.
Wireless Display System
2. Disconnect the transceiver at the generator end,
then reconnect it. You now have one (1) minute to
complete the setup process.
3. On the display select “Reset Radio”. The display
will show it is searching for the generator, this
process will last one minute and a countdown
timer will be displayed.
4. Once the time is up a message will be displayed
showing that the generator has been found. The
radio settings will be remembered for the next
time.
5. Re-set the exercise time.
TIME & DATE MENU
There is a display of the current time, day, and
date shown on the menu icon page. Only the
time display will update, the date display is
just a snapshot of the current date (Figure 11).

‹ ADD NEW DISPLAY
Time
A second (third or fourth) display can be added to
the network. Each display needs to be trained as to
what it’s network consists of. This is the function of
the “Add New Display” selection.
1. Locate the new display near the main display and
turn it on.
2. On the NEW display, go to the “Settings” menu
and select “Add me to Network”.
3. Choose a unique address for the additional display, for example one that does not conflict with
any other additional displays. If there are only
two displays, then any number (other than zero),
will do. Zero is used to cancel the command.
4. On the MAIN display go to the radio menu and
select “Add New Display”. Press enter on both
displays. A countdown timer will be displayed as
the two units re-train.
5. At the end of the period, the new display will
show that the training was successful.
‹ TEST RADIO LINK
This feature allows the “basic” data integrity of the
link to be tested, it may not be necessary to use this
feature. For ease of use, the display will NOT revert
to the status/alarm screen after one minute if no keys
are pressed.
Test data is sent over the link to the generator end,
and then sent back from the generator end to the
display. The data received is displayed on the bottom
line of the display. Good data is shown as a series of
forward slashes (//////). Timeouts on the link are displayed as the “#” character and corrupted data reply
messages are shown as the “@” character. The messages are termed “basic” because they are not error
checked or corrected.
Radio information such as signal strength, channel
number and quality is also shown alongside the test
data.

Selecting this menu permits setting the clock to the
correct time, day and date. This will only need to be
done the first time they system is powered up, or
to correct any small errors in the time. Use the two
arrow keys to set the correct time, day and date.
GRAPH MENU
The Graph menu permits graphing data in real
time on a rolling screen (Figure 12). Choose
what to graph from the following list:
• Utility Voltage
• Generator Battery Volts
• Generator RPM (in units of RPM x 100)
• Current up to 170A (20kW) - certain models only
The display is updated with a new point every 200ms
so it takes about 25 seconds to scroll the whole
screen. However new data is only read from the generator every two (2) seconds.
