tests of typical units, and is subject to, and limited
by, the temperature, altitude, fuel, and other condi-
tions specified by the manufacturer of the applicable
engines.
INTRODUCTION AND
DESCRIPTION
The package standby system includes all times
necessary for a completely automatic standby power
system as standard equipment.
DESCRIPTION
The package standby system is designed to au-
tomatically provide standby power to unattended
loads during electrical outages. Upon an interruption
of normal electrical service the packaged standby
system electrical control circuits will automatically
start the engine. The generator will produce electri-
cal power and the Automatic Transfer Switch (ATS)
will automatically transfer the electrical loads to the
engine-generator set. Upon restoration of normal
electrical service the emergency transfer switch will
sense return of the normal commercial power. The
Automatic Transfer Switch will retransfer the load
back to the normal commercial power source. The
engine control circuits will begin a cool-down cycle,
after which the fuel supply will be shut off and the
engine ignition system disabled.
These packaged standby systems consist ot two
major components:
1) AUTOMATIC TRANSFER SWITCH
A wall mounted ASCO 165 Automatic Transfer
Switch (ATS) designed for inside installation. The
transfer switch is UL1008 approved. A fourteen day
electronic exerciser circuit is installed in the ATS
as standard equipment. The ATS also contains the
power failure sensing circuitry necessary to start and
stop the engine generator set. The transfer switch is
also equipped standard with a 3 second start delay,
and a 15 second transfer delay to allow the engine
to warm up before transferring the load to the gen-
erator. When the line power is restored the ATS has
a 5 minute retransfer delay to allow the incoming util-
ity to stabilize before transferring back to line power
and then an additional 1 minute engine cool down
delay before the engine shuts down. Read and
understand the ATS owners manual before installing,
servicing or operating the transfer switch.

2) ENGINE / GENERATOR
The engine generator set consists of a Briggs &
Stratton Vanguard, twin cylinder, four cycle air
cooled engine. The engine is factory equipped to
run on LP or NG fuel. The engine operates at 3600
rpm and frequency regulation is maintained by the
engine governor within 4 cycles variation (62.5 Hz
- 58.5 Hz) from no load to rated load. The generator
is a brushless, single bearing, direct drive, rotating
field design. The generator is connnected to the
engine’s tapered (quill) crankshaft extension. The
engine generator is mounted in a drip-proof en-
closure for outside installation. Connection boxes
and terminal blocks are provided for all customer
connections (both AC output and DC control). A
customer supplied 12 volt 500 CCA (BCI group 26)
battery is required to complete the installation.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.

INSTALLATION
General Information
******************
***** WARNING *****
******************
Before proceeding with the installation be sure the
operation selector switch is in the stop position.
These engine generator sets are designed to be
mounted on a concrete pad outdoors only. As an
option a prefab pad may be used as long as proper
attention is paid to site preparation to insure the unit
will not move after installation. The transfer switch is
mounted next to your electrical entrance or distribu-
tion panel inside or outside the building. Consult a
qualified, licensed electrician or contractor to install
and wire the transfer switch. The installation must
comply with all national, state and local codes.
Before beginning the installation process check the
rating of the generator set and its transfer switch
rating. Be certain they can handle the intended
load and are compatible with the enterance voltage,
phase and current ratings. Plans for installation
should be prepared with proper attention to me-
chanical and electrical engineering detail to assure
a satisfactory system installation. The information
in this manual is offered only as a guide to finializing
your installation plans.

ENGINE GENERATOR SET MOUNTING
WARNING - Personal Injury
The enclosures on these units can become very
hot adjacent to the exhaust areas. Special care
must be taken when installing these units to
insure that the risk of contact by people is mini-
mized.
The unit’s main frame should be bolted to a four to
six inch thick cement pad. The engine-generator is
mounted on a sub-frame which is isolated with spe-
cial shock mounts on the main frame. This allows
the engine-generator to vibrate without affecting the
control panel on the main frame. (See page 20).
Do not install any shock mounts between the base
frame and the concrete pad. Engine vibration will be
transmitted to the control panel causing erroneous
start/stop cycles and premature control failure.
These units should be mounted a minimum of
24” from a structure. This will allow for ample
room to maintain and work on the generator set.
Units must be installed in accordance with all local,
state, and national codes. Consult your local agency
having jurisdiction for specific requirements.
FUEL INSTALLATION
The fuel supply should be as close as possible to the
engine. This will reduce the installation cost of fuel
runs. The information in this manual is offered to as-
sist you in providing the proper fuel for your engine.
However, this information is only provided to inform
you of the engine’s requirements and assist in mak-
ing you aware of the decisions you must make. In
no case should the instructions and information pro-
vided be interpreted to conflict with any local, state
or national codes. If in doubt, always consult your
local fire marshal, gas supplier or building inspector.
******************
***** WARNING *****
******************
FIRE HAZARD - All fuel runs should be installed
by a licensed fuel supplier.
To connect the fuel line to the generator set you will
connect your incoming fuel line to the 3/4 inch NPT
fitting located on the left side of the engine-genera-
tor set. This fitting is shipped with a plastic plug
installed to insure the fuel system stays clean.
For all vapor fuel systems the delivery pressure of
the fuel to the fuel solenoid on the unit must be four
to six ounces psi (per square inch) or 7 to 11 inches
W.C. (water column). These fuel pressures are
critical; failure to provide the proper pressure can
cause many problems ranging from a unit that will
not start to causing damage to the fuel system.
These units are normally tested on Natural Gas and
will have a tag hanging on the fuel hose indicating
on what fuel your unit was factory tested. If you are
running on LP or have to change fuel types at any
time see information on page 8 on LP/NG CONVER-
SION.
INSTALLING THE FUEL LINE
** NOTICE **
The engine generator sets are properly adjusted
before they leave the factory. A tag is attached to
the unit that specifies the fuel, natural gas (NG) or
propane vapor (LP) that the unit was set up and
tested on.
Line Size
Unit location will determine the size of fuel line that
is required to supply the engine with a constant fuel
pressure and volume. Refer to the tables below for
fuel line size, fuel consumption and recommended
tank size. For distances of 50 feet or over, a two
regulator fuel system is recommended. This is ac-
complished by installing a primary regulator at the
tank which will reduce the tank pressure down to
10 to 15 lbs. A secondary regulator is installed to
further reduce the fuel pressure to the required four
(4) to six (6) oz. operating pressure. This second-
ary regulator must be at least 10 feet from the
engine generator set, any closer installation will
require a larger line be installed to provide a fuel
reservoir. This is also true for the single duel stage
regulators, it should also be a minimum of 10 feet
from the unit. If this is not done the demand regula-
tor on the unit and the pressure regulator in the fuel
line will interfere with each other. When the two (2)
stage regulator system is used on LP, a fuel line size
of 1/2 to 5/8 inch is generally adequate for distances
up to 300 feet from the primary to the secondary
regulator. (Consult you local fuel supplier for your
exact requirements). The appropriate line size from
the table below is then installed from the secondary
regulator to the generator set.
******************
***** WARNING *****
******************
PERSONAL DANGER - Do not use galvanized pipe
in fuel line runs. The galvanized coating can be-
come eroded and flake off, causing possible obstruc-
tions in the regulator or fuel valve. The results could
range from inoperative engine to hazardous fuel
leaks.

* Allow an additional 3 feet for each standard
elbow. Do not use ‘street ells’ (restrictive).
**** CAUTION ****
Be careful when sealing gas joints. Excessive seal-
ing compound can be drawn into the solenoid, regu-
lator or carburetor causing an engine malfunction.
FUEL PRESSURE
LP & NG VAPOR FUEL Correct fuel pressure can-
not be stressed enough. The most common cause
for inoperative systems is an inadequate or incor-
rect fuel pressure. Performance of the engine is in
direct relation to the correctness of the fuel system.
Shown below is a diagram of a typical LP or NG
vapor fuel installation.
Notice the following tables give two (2) different
units of measuring fuel pressure. The first and most
accurate is the use of a simple water manometer. A
manometer is calibrated in inches of water column.
The second is with a pressure gauge calibrated in
ounces per square inch.
Reference numbers 1 through 3 in the diagrams
above are system parts supplied by the customer.
Reference number 4 is on the generator.

LP/NG FUEL CONVERSION
These generator sets are factory tested on Natural
Gas and will require no modifications for normal
operation on Natural Gas. The carburation system
has been preset and anti-tamper plugs have been
installed in the carburator as required by the EPA.
If you are operating on LP fuel you will have to
make the following modifications: On the left side of
the engine, above the starter there is a small two-
wire white connector lying loose. The wires will be
labeled 1 and 21. This connector has to be plugged
into the mating two-wire white connector coming out
of the carburator area on the left side of the unit.
This connection will engage an orifice in the carbura-
tor allowing the unit to operate on Liquid Propane
vapor fuel. NO other adjustments are required.
If you are reinstalling a unit that has been operating
on Liquid Propane vapor and you now want to oper-
ate it on Natural Gas all that you will need to do is
unplug this connector.
LUBRICATON
Before starting the engine, check and fill the crank-
case with the proper weight/grade oil, as recom-
mended by the engine manufacturer’s maintenance
instructions. The necessity of using the correct oil,
and keeping the crankcase full cannot be over em-
phasized. DO NOT OVERFILL THE ENGINE, Use
the dipstick.
INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check
to be sure the selector switch remains in the “off”
position. This should be your last step before initial
start-up.
A customer supplied twelve-volt battery is required to
complete the installation. Installation of the high-
est CCA rated battery, within the correct BCI group
(size), will increase cold weather starting perfor-
mance. Gel batteries should not be used with the
battery tender installed in the generator enclosure.
Model Voltage BCI Group MINIMUM
CCA Rating
ULPSS8B2W 12 26 500
Installation and servicing of batteries must be per-
formed or supervised only by personnel knowledge-
able of batteries and the required precautions. Keep
unauthorized personnel away from batteries.
When installing or replacing batteries, use the proper
group/size starting battery. The battery should be
a Maintenance Free lead acid design. Deep cycle
batteries will not work for this application.
CAUTION - PERSONAL DANGER
CAUTION - NEVER dispose of a battery in a fire.
The battery is capable of exploding.
CAUTION - DO NOT open or mutilate the battery.
Released electrolyte is known to be harmful to the
skin and eyes and to be very toxic.
These engine generator sets are all NEGATIVE
ground. Be very careful not to connect the battery in
reverse polarity, as this may short circuit the battery
charging system on the engine.
CAUTION - A battery presents a risk of electrical
shock and high short circuit current. The following
precautions must be observed when working with
batteries.
1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the bat-
posts to be sure they are free of corrosion.
4. Always connect the battery positive cable first
and then connect the battery negative cable.
When removing the battery cables from the bat
tery reverse the procedure, disconnect the nega
tive cable first and then the positive cable.
5. Be sure all connections are tight and coat the
terminals and cable ends with dialectic grease.
WARNING - The electrolyte is a diluted sulfuric acid
that is harmful to the skin and eyes. It is electrically
conductive and corrosive. The following precautions
must always be taken.
* Always wear full eye protection and protective
clothing.

9
11075-00 60706-211
* Where electrolyte contacts the skin, wash off im
mediately with water.
* If electrolyte contacts the eyes, flush thoroughly
and immediately with water and seek immediate
medical attention.
* Spilled electrolyte is to be washed down with an
acid neutralizing agent. A Common practice is to
use a solution of one pound of bicarbonate of
soda (baking soda) to one gallon of water. The
bicarbonate of soda solution is to be added until
the evidence of reaction, foaming, has ceased.
The resulting liquid is to be flushed with water
and the area dried.
DANGER - Explosive Fire Risk
* Never smoke when near batteries.
* Do not cause a flame or spark in the battery area.
* Always discharge static electricity from your body
before touching batteries by first touching a
grounded metal surface.
SERVICING BATTERIES
Batteries used on these units may over time lose
water. This is especially true if you are using a
trickle charger to maintain your battery. When refill-
ing the battery with water use only distilled water.
Tap water will shorten the service life of the battery.
Never fill the battery above the fill line. Over filling
above the upper level line may cause the electrolyte
to overflow, resulting in corrosion to the engine or
nearby parts. Immediately wash off any spilled elec-
trolyte following the procedure above.
BATTERY CHARGING
Units equipped with electric start have a small fly-
wheel charger built into the engine flywheel assem-
bly for recharging the starting battery. This flywheel
charger generates a small AC current that passes
through a rectifier/regulator assembly on the engine
to produce a DC charging current. This circuit is not
designed to be used as a battery charging circuit to
recharge dead batteries.
**** CAUTION ****
EQUIPMENT DAMAGE - Always connect the posi-
tive cable first and the negative cable last. When
disconnecting, it is the negative first and the positive
last. Failure to connect and disconnect in the proper
sequence can cause equipment damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the engine starter;
the negative (-) battery terminal is connected to the
negative cable (ground) from the engine generator
assembly. All connections must be clean and tight.
Check the electrolyte (fluid) in the battery periodi-
cally to be sure it is above the plates. Never allow
the battery to remain in a discharged condition.
**** CAUTION ****
EQUIPMENT DAMAGE - NEVER JUMP START
these units. Doing so will destroy the engine control
module rendering the unit non-operational. Remove
and fully recharge the battery before attempting to
start.
CONNECTING THE BATTERY CHARGER
A two-stage battery tender is provided on all PSS
series generators. This battery tender charges at
a rate of 750 mA until the battery is fully charged
and then automatically switches to a 13.2 VDC float
charger. The charger has an indicator light on it,
red indicates it is charging, and green indicates it is
in the storage mode (float charge). This charger is
mounted on the engine generator set, located be-
hind an acces cover on the right side of the unit.
The battery tender receptacle is to be powered by
a GFCI circuit and installed in accordane with the
United States National Electric Code. These AC
wires can be run in the same conduit as the the
other AC leads from the generator. It is suggested
that this circuit be fused for 15 amps. Terminal block
connections have been provided in the customer
connection area of the engine generator set. See
Page 10 for diagram.
** NOTICE **
The battery tender is not intended to recharge a bat-
tery which has become completely discharged. It is
designed to produce enough current to recharge a
slightly low battery, maintainging it fully charged.
MOUNTING THE AUTOMATIC
TRANSFER SWITCH (ATS)
******************
***** WARNING *****
******************
EQUIPMENT DAMAGE - Protect the switch from
construction grit and metal chips to prevent mal-
function or shortened life of the switch. Contactors
returned for warranty consideration with foreign
materials inside of them will not be warranted.
Before installing the ATS you must first ensure that
the transfer switch is large enough to handle your
complete distribution panel. If you are installing a
100 amp transfer switch the main line circuit breaker

11075-00 10 60706-211

11
11075-00 60706-211
must not be larger than 100 amps. If you have a
125, 150, 200 amp or larger system and want to use
a 100 amp transfer switch, you will not be able to
transfer the complete electrical system. In this case
it will be necessary to install a secondary emergency
distribution panel. NOTE: THE MAXIMUM OUT-
PUT OF THE GENERATOR IS 33 AMPS AT 240
VOLTS. You must also take into consideration when
deciding whether to install an emergency distribution
panel.

To gain acces to the customer connections remove
the end door panel opposite the muffler end. All
connections including AC and DC connections to the
ATS, 120 Volt power connection for battery charger,
and battery installation are made behind this door
panel. After removing the door panel you will need
to remove the cover over the customer connection
box. Remove the two bolts using a 7/16 inch open
end wrench, then remove the panel. See pages 19
and 20 for generator set and pad layout.
Four AC power leads are required between the
generator and the ATS. Two hot leads, a neutral
and a ground lead. You will then need to run both a
neutral and ground lead in addition to the two power
leads all the way back to your disribution panel. The
two power leads from the generator are marked G1
and G3.
In addition to the power leads you will also need to
run a three wire 120 volt, 15 amp circuit from your
distribution panel to the generator. This circuit wll be
used to power the battery charger.
The last two wires you will need are the DC control
leads (14 or 16 gauge) for the start circuit in the ATS.
These last two connections will be discussed later in
more detail.
WINCO UL ATS (ASCO 165)
See the ASCO installation manual for additional
details on proper wiring of the Automatic Trans-
fer Switch.
The standby generator terminals in the ATS are
marked “ALTERNATE L2 & L6”. The “hot” leads
G1 and G3 from the generator are connected to the
terminals L2 & L6.
The normal line power terminals in the ATS are
marked “PREFERRED - L1 & L5”. The “hot” line
power leads are L1 and L3 from your normal power
supply are connected to terminals L1 and L5.
The load terminals in the ATS are marked “LOAD
- L3 & L7”. The leads to the load distribution panel
are connected to terminals L3 & L7.
The neutral leads from all three locations are con-
nected to the isolated terminal lugs on the sidewall
of the cabinet. This terminal block is labeled “NEU-
TRAL” and the terminal lugs are mounted on red
isolation standoffs.
The ground leads from all locations are connected to
the grounded terminal lugs also located on the side
wall. This set of terminals is labeled “GROUND”.
INSTALLATION NOTES
The load current carrying wires (L) and (T) must be
sized to handle the maximum load current without
excessive voltage drop. By code, the wire must be
heavy enough to handle the full current rating of the
main line circuit breaker (or fuse) in the enterance
(or sub-panel) protecting the contactor switch.
All wires should be installed in rigid or flexible con-
duit.

11075-00 12 60706-211
Because of the many different types of service,
feeder, and distribution equipment, no specific wiring
instructions can be provided. It is, however, recom-
mended that copper wire be used. In all cases it is
essential that while the load is connected to the gen-
erator, there can be absolutely no feedback from the
generator to the power line or the power line to the
generator. When properly installed, the normal ATS
control and safety systems will eliminate all paths for
feedback. Check with your local electrical inspector
on applicable local, state and federal codes.
******************
***** WARNING *****
******************
A service disconnect must be installed in front of the
ATS panel as the ATS is not service enterance rated.
This will alow you to test the generator under load.
Should you ever have to work on the switch, you will
be able to disconnect the power and work on the
switch cold without having the power company pull
your meter.
To wire the automatic transfer switch into the exist-
ing wiring, first determine which circuits will be on
the emergency load circuit. If the entire load is to
be transferred, the transfer switch can be wired in
directly after the watt-hour meter and the service
enterance, providing the service enterance ampere
rating is within the transfer switch’s rated capability.
If only specific circuits are to be powered under
emergency power failure conditions, and additional
distribution panel designated “emergency distribution
panel” must be installed.
All selected emergency circuits are removed from
main distribution panels and reinstalled in the emer-
gency distribution panel. Suggested circuits: freez-
er, refrigerator, furnace, emergency lights, sump
pump, emergency outlet circuits, etc. Total running
load must not exceed generator rating.

**** CAUTION ****
Never run the AC and DC wiring in the same con-
duit.
ASCO 165 UL SWITCH
Your DC connection points in the ASCO 165 UL ATS
are on the terminal block in the upper right hand
corner of the ATS panel. The terminal block (TB7)
is numbered 1 through 9. These terminals will
accept # 22 - # 14 AWG stranded wire. It is recom-
mended that you use # 16 AWG for distances up
to 200 feet. You need to run two (2) wires from the
engine generator set to the transfer switch. You
will be using terminals 4 and 5, wire Start # 23 will
connect to terminal # 5 and wire Battery Negative #

PROCEDURE
Engine Generator Set only
The engine control module (ECM) is manufactured
by Deep Sea Electronics. Model 3110 is used on
this engine generator set. See picture below. Ad-
ditional information on the DSE 3110 is on pages 14
through 17.
Manual Operation
Press and release the red Stop/Reset button. Then
press and release the green Start Engine button.
The engine generator will crank and start automati-
cally. If the engine fails to start correct the problem
before proceeding.
With the engine running smoothly, check the no load
voltage and frequency at wire # 1 and # 4 (L2 and
L6 in the ASCO ATS) on the generator terminal block
in the ATS. The voltage should be 240 volts plus or
minus nominal. The frequency should be between
61.5 to 62 hertz (Hz). The voltage should also be
checked between the hot terminals (L2 and L6) and
the neutral to be certain of a balanced voltage output
and a solid neutral connection. The voltage should
be about on half of the line to line voltage.
** NOTICE **
If for any reason during the check out procedures
the voltage and frequency are not correct, press the
Stop/Reset button and correct the trouble before
proceeding.
After verifying the voltage and frequency are correct,
press the Stop/Reset button. This will shut off the
engine immediately.
Transfer Switch & Engine Generator
Automatic (remote) Operation
This procedure checks the electrical operation of
the automatic transfer switch. If the actual operation
does not follow this procedure, consult the trou-
blshooting section in the transfer switch manual.
1. Turn on the preferred source (utility) circuit
breaker. The utility source acceptable light should
now come on as well as the transfer switch on utility
light. If these lights fail to come on recheck your
incoming power to insure you have 240 volts nomi-
nal. If not, troubleshoot your utility source before
continuing.
******************
***** WARNING *****
******************
PERSONAL INJURY HAZARD - Install front cover
in transfer switch before operation. An electrical sys-
tem fault could cause a flash and severe personal
injury.
2. Press and release the Auto button on the en-
gine control module (ECM). The auto mode icon will
appear on the screen. The unit is now ready to be
operated from the Automatic Transfer Switch.
3. Turn on the altenate source (generator) curcuit
breaker.
4. Press and hold the Push to Test button until
the generator (alternate source) acceptable light
comes on and stays on. Then release the button.
This will start up your generator set.
This light indicates that the generator is running and
the output voltage and frequency are within accept-
able limits. Under normal conditions this light should
come on in 5 to 10 seconds. If the light does not
come on and stay on a malfunction has occurred.
Either the unit didn’t start or the voltage or frequency
is incorrect. Correct the problem before continuing.

11075-00 14 60706-211
5. About 15 seconds after the generator (alter-
nate source) acceptable light comes on, the auto-
matic transfer switch should transfer the load from
the utility to the generator. At that time the Transfer
Switch on generator light should come on.
6. The generator will stay connected to the load
for about 5 minutes at which time the transfer switch
will transfer the load back to the utility. At the time it
transfers back to utility the Transfer Switch on Utility
light should come on and the Transfer Switch on
generator light should go out. To bypass this five
minute time delay you can press and release the
Push to Test button again at any time.
7. After the load retransfer to the utility, the gen-
erator will continue to run for about 1 minute (without
a load) and then shut down. The Generator ac-
ceptable light will go off indicating the generator set
has shut down. This completes the functional test
of the transfer switch and the generator set. If you
want to leave the generator in the Automatic Start
mode you can leave the engine control module in
the auto mode. If you have additional work to do or
don’t want to leave the engine generator set in the
automatic position start mode press and release the
stop/reset button In the off mode the engine genera-
tor set will not start or run.
GENERATOR EXERCISER CIRCUIT
The automatic generator exerciser is configured to
automatically exercise the generator for 20 minutes
once every 14 days.
In order to set and test the exercise circuit the
engine control module must be set in the auto
mode.
SETTING THE EXERCISER CIRCUIT
Press and release the Automatic Generator Exer-
ciser button. After about 8 seconds the exerciser
light flashes 14 times to indicate that the exerciser
circuit has been set. The number of flashes indi-
cates the number of days until the next exercise
period. This 20 minute period will occur at approxi-
mately the same time of the day the button was
pressed.
DISABLING THE EXERCISER CIRCUIT
Press and hold the Automatic Generator Exerciser
button until the light goes off, the light flashes then
goes off.
ENABLING THE EXERCISER CIRCUIT
Press and hold the Automatic Generator Exerciser
button until the light goes off, the light flashes then
goes off. After about 8 seconds the exerciser light
flashes fourteen times to indicate that the exerciser
circuit has be re-enabled.
******************
***** WARNING *****
******************
WITH A TOTAL POWER FAILURE (UTILITY
POWER FAILS AND THE GENERATOR FAILS TO
START AND RUN) THE EXERCISER MUST BE
RESET AFTER THE POWER IS RESTORED.
CLEARING AN “ERROR” CODE
An error codes occurs on the ASCO control board if
the generator set fails to start or there is some other
malfunction. BOTH Transfer Switch lights will be
blinking together. The Automatic Generator Exer-
ciser light will be blinking a number of times then
pause. This number gives the error code reason
from page 8 of the ASCO 165 owner’s manual. To
clear this code press and release the Push to Test
button once. Then troubleshoot the problem accord-
ing to the ASCO 165 owner’s manual.
This completes your installation and unit testing.

PREVENTIVE
MAINTENANCE
Reasonable care in preventive maintenance will
insure high reliability and a long life for the engine
generator set and Automatic Transfer Switch.
*****************
***** WARNING *****
*****************
When performing any type of maintenance on this
equipment make sure the selector switch on the en-
gine generator is in the off position. If you are work-
ing in the Automatic Transfer Switch, confirm with a
reliable meter that all power has been disconnected.
AUTOMATIC TRANSFER SWITCH
Clean and inspect the switch once a year. de-ener-
gize all power sources, both line and engine genera-
tor set, then brush and vacuum away any excessive
dust or dirty accumulation. You can at this time with
the contactor de-energized remove the contactor
covers and check the contacts. Make sure contacts
are clean and not burned or pitted.
ENGINE GENERATOR SET
Service the engine in accordance with the engine
manufacturers manual provided with your new
equipment. Routinely remove debris and dirt from
around the inside generator enclosure. Insure that
the air intakes are free from leaves and other debris
at all times.
Clean and inspect battery terminals a least twice a
year. Check the battery water level at least twice a
year also.
Other than keeping the generator clean and free of
debris there is no other routine or preventative main-
tenance required, as long as the generator is run
biweekly to keep it dry and in good working order.
COLD WEATHER OPERATION
Extreme cold weather operation requires special
considerations. Higher CCA batteries are required
for cold weather starting, 650 CCA or larger are rec-
ommended. In addition you should consider install-
ing an oil heater kit and a battery warmer for reliable
starting during cold weather.

STOP/RESET (Red Button) This button places the module into its “Stop/
Reset” mode. This will clear any alarm conditions for which the triggering
criteria have been removed. If the engine is running and the module is in
Stop mode, the module will automatically instruct the changeover device to
unload the generator. (Close generator becomes inactive (if used)). The fuel
supply de-energizes and the engine comes to a standstill. Should a remote
start signal be present while operating in this mode, a remote start WILL NOT
occur.
AUTO (White Button) This button places the module into its “Automatic”
mode. This mode allows the module to control the function of the generator
automatically. The module will monitor the remote start input and once a start
request is made, the set will be automatically started and placed on load.
Upon removal of the starting signal, the module will automatically transfer the
load from the generator and shut the set down observing the stop delay timer
and cooling timer as necessary. The module will then wait the next start event.
