GENERAL HAZARDS
• For safety reasons, the manufacturer recommends that the
installation, initial start-up and maintenance of this equipment
is carried out by a Dealer.
• The engine exhaust fumes contain carbon monoxide, which
can be DEADLY. This dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness or even death.
Do NOT alter or add to the exhaust system or do anything that
might render the system unsafe or in noncompliance 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 to 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. The
generator MUST be installed outdoors.
• When working on this equipment, remain alert at all times.
Never work on the equipment when physically or mentally
fatigued.
• Inspect the generator regularly, and contact the nearest Dealer
for parts needing repair or replacement.

2

• 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, then remove the POSITIVE, POS or (+) cable. When
reconnecting the cables, connect the POSITIVE cable first, the
NEGATIVE 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 when it is in
operation. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate
covers, guards and barriers are in place, secured and/or locked
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.
• The National Electrical Code (NEC) requires the frame and external
electrically conductive parts of the generator to be connected to
an approved earth ground. Local electrical codes also may require
proper grounding of the generator electrical system.
• After installing this home standby electrical system, the generator may crank and start at any time without warning. When this
occurs, load circuits are transferred to the STANDBY (generator) power source. To prevent possible injury if such a start and
transfer occur, always set the generator’s AUTO/OFF/MANUAL
switch to its OFF position before working on equipment and
remove the 15A fuse from the generator control panel.
• 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
• For fire safety, the generator must be installed and maintained
properly. Installation 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 in accordance with the manufacturer’s
instructions and recommendations. Following proper installation, do nothing that might alter a safe installation and render
the unit in noncompliance with the aforementioned codes,
standards, laws and regulations.

Wireless Display System
• Keep a fire extinguisher near the generator at all times.
Extinguishers rated “ABC” by the National Fire Protection
Association are appropriate for use on the standby electric
system. Keep the extinguisher properly charged and be familiar
with its use. Consult the local fire department with any questions pertaining to fire extinguishers.

EXPLOSION HAZARDS
• 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.
• Gaseous fluids such as natural gas and liquid propane (LP)
gas are extremely EXPLOSIVE. Install the fuel supply system
according to applicable fuel-gas codes. Before placing the
home standby electric system into service, fuel system lines
must be properly purged and leak tested according to applicable code. After installation, inspect the fuel system periodically
for leaks. No leakage is permitted.

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
(1-800-333-1322).

INTRODUCTION
The wireless remote monitor system consists of two identical
radio transceivers, one mounted near the generator (generator
transceiver) and the display unit which should be in a convenient
viewing location. The system has a “line of sight” range of about
500 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:
• An independent (of the generator Alarm log) time/date stamped
history of generator events such as starting and stopping
• Allows remote starting and stopping of the generator
• Facility to set an exercise time and day from the display
• A separate battery backed clock (with date facility) which is
synchronized to the generator clock. If power is removed from
the generator, time and date can be automatically restored from
this clock.
• Ability to add extra displays
• Graphing capability
The unit can be either battery powered or fed from the AC adapter
supplied (Part No. 0G4904). This adapter is rated for 100/240
VAC, 50/60 Hz operation. 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, 10 year life battery.

BATTERY OPERATION
The wireless display unit can be operated either from a plug in wall
transformer or from three AAA alkaline batteries. The unit is NOT
designed to run continuously on battery power. 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. 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.

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.

DISPLAY INSTALLATION

5.

For easier installation, the batteries should first be fitted into the
display unit (Figure 7). 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 as described
in the previous section.

Figure 7 — Open Display Unit

6.

Once the generator is found, the radio link is now established
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. Repeat steps 2 and 3 with the Display closer to
the generator.
If the generator is not talking to its 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

Plug the wall transformer into the display so as not to use up
the batteries. Become familiar with the radio menu (by reading
the manual in conjunction with operating the display).
Monitor the signal strength by looking at the display of signal
strength bars on the display (Figure 11). Note that it takes
a few seconds for the display to update the signal strength
display. Relocate the display if the signal strength is poor or
non-existent.
Mount the display using the holes on the back to hang onto
two suitably sized fixing screws 2¼ inches (57mm) apart. It
should be vertically mounted on a wall BETWEEN studs for
maximum signal strength (Figure 9).

Reset the generator transceiver by unplugging and then
reconnecting the 8-way connector (refer back to Figure 4).
Immediately proceed with step 3.
IMMEDIATELY turn on the remote unit. Up to one minute will
pass while the generator and remote unit synchronize.
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.

8.

Once a link is established, the display will "remember" its
own generator and will not need to search for it again after
it is turned off and back on. If the battery is ever disconnected at the generator end, the generator will search for the
display when the battery is reconnected. It is important that
the display is powered from the wall transformer at this time
and not its internal battery. This is because the display would
normally be in sleep mode when powered from its battery and
the generator would be unable to find it.
Set the time and date into the clock, use the instructions
given in the "Time and Date Menu" section. The time and date
will be remembered even if the battery goes dead. There is a
separate, internal 10 year battery for this function.
The communications LED will light continuously to show data
is being received. A flashing LED indicates the unit was unable
to find the generator.
Set an exercise day and time now (see "Exercise Menu" section).

THE COMMUNICATIONS LED
The communications LED will light continuously 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 poorer reception.

GENERATOR COMMUNICATIONS
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 its 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 10). Check the wiring and connection to
the generator.

Figure 10 — Sample Alarm

THE DISPLAY
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.

BACKLIGHT
The backlight is lit whenever a key is pressed. It will remain lit for
20 seconds if there are no further key presses. If an alarm occurs,
the backlight will flash at a one (1) second rate (not if battery
powered).

BUTTONS
Operation of the display is controlled by three (3) buttons labeled
Δ, ∇, and Enter. These buttons are used to navigate the display
to the required page, or to enter data. The Δ, ∇ buttons are also
referred to as the arrow keys. Holding down a button for more than
half a second will cause it to auto repeat until it is released.

BATTERY AND SIGNAL STRENGTH INDICATORS
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 11). 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 50-75% 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, one bar
represents weak signal strength. Two or three bars is the normal
indication.

TEST MENU
The test menu permits starting and stopping the generator.
Use the arrow keys to navigate to the appropriate option.
If choosing to start the generator, the two arrow keys will
need to be pressed together to confirm the command. To cancel
the command, press the enter key.
If there is an automatic transfer switch, there is the option to run
the generator and transfer onto generator power. Once the generator is started or stopped, the state of the generator will be shown
by a “*” symbol next to the command issued.

Wireless Display System
For example:
Normal Start*

You started the generator at normal
speed.
You started the generator & transferred
to generator power
You stopped the generator

Start & transfer*
Stop generator*

There is a one minute cool down time after you stop the generator,
so it will continue to operate for one minute after the stop command is issued. In the event that the stop command fails (such as
if you take the display out of range, you can either retry the stop
command or manually stop the generator by switching it to the
“off” position.

HISTORY MENU
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 key switch 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 log. This log is independent of the
log displayed at the generator and will log ALL events, not just
alarms.

When entering the history menu, the most recently logged event
(Event 1) will be displayed. The actual event will be shown as a
message on the left hand portion of the screen (Figure 16). The
time and date of the event will be shown on the right hand part of
the screen, and the event number displayed on the underlined title
bar. By using the arrow keys, navigate through the events which
are stored in chronological order. Event 1 is the most recent and
event 100 is the oldest. The events are stored in a circular fashion
so it's possible to scroll from Event 1 back to event 100 by using
the “UP” arrow key. The history log can be cleared from the

ADJUST CONTRAST
The display contrast can be adjusted using the two arrow keys.
Once the desired contrast level is reached, press the enter key to
store it.

CHOOSE LANGUAGE
The display can be set to any one of three (3) languages. The
choices are English, French, and Spanish. This can be changed at
any time by scrolling to the settings page and selecting "Choose
Language". This setting is saved until changed by the user.
Removing power or removing batteries will not change this setting.

EXERCISE MENU
Normally the exercise time is set at the generator control
board. If an exercise time has not been set on the control
board, it will flash an alarm message and an alarm will
also be set on the wireless display – “EXERCISE TIME NOT SET”.
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 of
the exercise. The data will be sent to the generator. Confirm it by
rechecking the exercise time on the base station display after a few
seconds (it takes a few seconds for the radio to update its data.
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 the clock on the generator and
the clock in the base station must be synchronized, this is normally
the case and it is automatically checked and corrected every ten
minutes. 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.

RADIO INFORMATION

RESET RADIO

This selection shows statistics about the radio link. There is a
display of signal quality as a percentage, as well as an indication
of the current system channel. For ease of use, the display will
NOT revert to the status/alarm screen after one minute if no keys
are pressed.

Normally the system will set itself up out of the box. However, if
either of the transceivers need to be replaced (the display or the
generator end), 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 is discharged, the system will remember the
radio settings.

If the signal quality is low but the signal strength is good, there may
be some interference. See the section on "Changing Channels".

CHANGING CHANNELS
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.
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 by removing
the 7.5A fuse from the front cover of the control panel. Place
the ON/OFF/AUTO switch in the OFF position and turn OFF the
240 VAC utility source voltage to the control panel. Perform
steps 2, 3 and 4 while the fuse is removed.
2. Go to the radio menu and select "Reset radio". This will try to
establish a link but it will fail. The process will take about one
minute.
3. Go to "Change Channel" and select a new channel. There are
16 channels to choose from.
4. Go back and select the "Reset Radio" command.
5. Insert the 7.5A fuse back into the control panel to reapply
power to the generator end of the link. Turn on the 240 VAC
utility source voltage to the control panel and place the ON/
OFF/AUTO switch in the AUTO position.
6. 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.

If communications are totally lost for an unexplained reason, you
may want to perform a new radio setup. To do this, repeat the
steps in the DISPLAY INSTALLATION section.

ADD NEW DISPLAY
An extra remote display can be added to the network. Each display
needs to be trained as to what its network consists of. This is the
function of the “Add New Display” selection.

5.

Locate the new display near the main display and turn it on.
On the NEW display, go to the “Settings” menu and select
“Add me to Network”.
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.
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.
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 (//////). Time-outs 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 channel number and quality are also
shown alongside the test data.

TIME & DATE MENU
Time

There is a live, updating display of the current time, day,
and date shown on the menu icon page (Figure 17).

Figure 17 — Time & Date Menu

GRAPH MENU

The Graph menu permits graphing data in real time on a
rolling screen (Figure 18). Choose what to graph from the
following list:

• Utility Voltage
• Generator Battery Volts
• Generator RPM (in units of RPM x 100)
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.

Figure 18 — Sample Graph of Engine RPM

Selecting this menu permits setting the clock to the correct time,
day and date. This will only need to be done the first time the base
station 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.
The separate clock in the generator is synchronized to this clock
when it is changed. Synchronization is checked and corrected, if
necessary, every ten minutes. If the clock or date is changed at the
generator, the clock at the base station is also changed automatically (The two clocks are linked together and can be changed at
either end of the link).
