 This symbol points out potential fire hazard.

 This symbol points out potential electrical shock

hazard.

Study these SAFETY RULES carefully before install-

ing, operating or servicing this equipment. Become

familiar with this Owner’s Manual and with the unit.

The generator can operate safely, efficiently and reli-

ably 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 warn-

ings 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.

DANGER

 Despite the safe design of this generator,

operating this equipment imprudently, neglect-

ing its maintenance or being careless can cause

possible injury or death. Permit only responsible

and capable persons to install, operate or main-

tain this equipment.

 Potentially lethal voltages are generated by

these machines. Ensure all steps are taken to

render the machine safe before attempting to

work on the generator.

 Parts of the generator are rotating and/or hot

during operation. Exercise care near running

generators.

 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 tech-

nician who is familiar with applicable codes, stan-

dards and regulations. The operator also must com-

ply 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 electri-

cal 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 monox-

ide 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 venti-

lating air is critical in any room or building hous-

ing 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 seri-

ously 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.

•

The engine exhaust from this product

contains chemicals known to the state

of California to cause cancer, birth

defects or other reproductive harm.

•

WARNING:•



This product contains or emits chemicals

known to the state of California to cause

cancer, birth defects or other reproductive harm.

•

WARNING:•



 SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe

operation be copied and posted in potential hazard areas. Safety should be stressed to all

operators, potential operators, and service and repair technicians for this equipment.



 SAVE THESE INSTRUCTIONS – This manual contains important instructions that should be

followed during installation and maintenance of the generator and batteries. 

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 gen-

erator, 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 con-

ditions 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 gen-

erator 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 repair-

ing 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 con-

ductive parts of the generator to be connected to

an approved earth ground and/or grounding rods.

This grounding will help prevent dangerous electri-

cal shock that might be caused by a ground fault

condition in the generator set or by static electric-

ity. Never disconnect the ground wire.

Wire gauge sizes of electrical wiring, cables and

cord sets must be adequate to handle the maxi-

mum 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 pos-

sibly fatal electrical shock.

Connecting this unit to an electrical system nor-

mally 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 operat-

ing. 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 person-

nel, 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, imme-

diately 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 imple-

ment, 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 equip-

ment. Jewelry can conduct electricity resulting in

electric shock, or may get caught in moving com-

ponents 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 extin-

guisher 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 com-

bustible materials are left in the generator com-

partment, or on or near the generator, as FIRE or

EXPLOSION may result. Keep the area surround-

ing 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 regulat-

ing the storage and handling of fuels. Inspect the

unit’s fuel system frequently and correct any leaks

immediately. Fuel supply lines must be prop-

erly installed, purged and leak tested according to

applicable fuel-gas codes before placing this equip-

ment 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.

•

OPERATION AND MAINTENANCE

The operator is responsible for proper and safe use

of the equipment. The manufacturer strongly recom-

mends that the operator read this Owner's Manual

and thoroughly understand all instructions before

using this equipment. The manufacturer also strong-

ly 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 capa-

ble 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 genera-

tor 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 gen-

erator



•

Facility to set an exercise time & day from the dis-

play

Facility to adjust the “bad” utility voltage thresh-

old

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 opera-

tion, 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 bat-

tery, 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 cir-

cuit 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

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 dis-

play.

4. The display will show that it is searching for the

generator and the yellow LED may flash occasion-

ally as it receives data from the generator trans-

ceiver. 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 genera-

tor 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 there-

fore 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 dis-

play 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) sec-

ond 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 maxi-

mum signal strength (Figure 3).

Figure 3 — Mounting Holes

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).

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.

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 it’s transceiver, but the radios are talking

to each other, this will be indicated by an appropri-

ate alarm which will be displayed after a seven (7)

second period (Figure 4). Check the wiring and con-

nection to the generator.



BACKLIGHT

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 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 +, —, 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.

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 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 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 (about 45%), one bar represents weak

signal strength. Two bars is the normal indication.

the generator, the two arrow keys will need to be

pressed together to confirm the command. To cancel

the command, press the enter key.



Wireless Display System

If the generator can run at a low speed (Quiet Test

QT), this option is available. If there is an automatic

transfer switch, there is the option to run the genera-

tor and transfer onto generator power. Once the gen-

erator is started or stopped, the state of the generator

will be shown by a “*” symbol next to the command

issued. For example:

Normal Start* You started the generator at

normal speed.

Start & transfer* You started the generator

& transferred to generator

power

Low speed start* You started the generator at

low speed (Quiet Test)

Stop generator* You stopped the generator

There is a one minute cooldown 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 switch-

ing 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 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

log.

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 10). 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 “SETTINGS” menu.

Wireless Display System

EXERCISE MENU

Normally the exercise time is set on the gen-

erator 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”.

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 instruc-

tions to set the time and day. The wireless display cal-

culates the difference in time from the exercise date

and time to the current date and time, and down-

loads 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 com-

mand in the radio menu section).

RADIO MENU

The following list of options will be presented:

Radio information

Change Channel

Reset Radio

Add New Display

Test Radio Link

RADIO INFORMATION

This selection shows statistics about the radio link.

There are displays of signal strength and signal qual-

ity as percentages, 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.

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 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 auto-

matically 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 estab-

lish 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 chan-

nel 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 chan-

nel. 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 transceiv-

ers ( the display or the generator end), or if power is

ever lost to the generator end (such as a flat genera-

tor 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.

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.

ADD NEW DISPLAY

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 dis-

play, 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 dis-

played as the “#” character and corrupted data reply

messages are shown as the “@” character. The mes-

sages 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.

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 gen-

erator every two (2) seconds.
