INITIAL START UP
*************
***** WARNING *****
*************
DO NOT jump start these engine generator sets. Starting
these units on a low battery or jump starting them will
cause damage to the engine control module.
Use the following checklist to verify correct installation
before starting the engine:
F Engine oil.* Check level & fill as required with
proper grade/qty.
F Unit mounting base properly bolted down.
F Clearance for service and maintenance on all
sides.
F Proper fuel line material and size.
F
All fuel line connections tight.
F Fuel line protected and a moisture trap installed
(may be required for N.G.).
F LP/NG pressure O.K. 4-6 Oz. (7-11" WC).
F
Battery connections clean and tight.
F Battery fully charged.
F All A.C. and D.C. wiring installed and properly
protected.
* Refer to engine owners manual for proper
levels and type.
After completing the above checklist, the engine genera-
tor set is ready for the initial start-up test.
PROCEDURE
Move the selector switch on the engine generator to the
“RUN” position. The engine generator will crank and
start automatically. If the engine fails to start, return
selector switch to the “stop” position and correct the
trouble before proceeding.
With the engine running smoothly, check the no load
voltage and frequency at terminals L2 and L6 in the
ASCO ATS on the generator terminal block in the ATS.
The voltage should be between 242 to 248 volts. The
frequency should be between 61.5 to 62 hertz (Hz). The
voltage should also be checked between the hot termi-
nals (L2 and L6) and the neutral to be certain of a
balanced voltage output and a solid neutral connection.
The voltage should be about one half of the line to line
voltage or approximately 121 to 124 volts AC between
both power feeds and neutral.
** Notice **
If for any reason during the check out procedure the
voltage and frequency are not correct, turn the selector
switch to the “STOP” position and correct the trouble
before proceeding.
After verifying the voltage and frequency are correct, turn
the selector switch to the “STOP” position. The unit
should shut off with no time delay. You are now ready to
test the automatic start function.
Transfer Switch & Engine Generator
This procedure checks the electrical operation of the
automatic transfer switch. If the actual operation does
not follow this procedure, consult the troubleshooting
section in the transfer switch manual.
If you are not using the ASCO165 transfer switch you will
need to follow the information in the manual for your ATS
for initial starting and testing procedure. This procedure
will also test the interface between the transfer switch
and the engine generator set.

***** WARNING *****
*************
PERSONAL INJURY HAZARD - Install front cover on
to transfer switch before operation. An electrical system
fault could cause a flash and severe personal injury.
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 nominal. If not,
troubleshoot your utility source before continuing.
2. Move the toggle switch in the generator from the
stop position to the auto position. The unit is now
ready to be operated from the Automatic Transfer
Switch.
3. Turn on the alternate source (generator) circuit
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.
