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 installa-
tion 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 generator
set is ready for the initial start-up test.
PROCEDURE
Engine Generator Set only
Move the right hand toggle switch from stop to the normal
position. The alarm light should go out. Next move the left
hand toggle switch from the auto to the run position. You
should hear the fuel solenoid engage at this time. Next lift
the toggle switch to the start position and hold. The
starter should engage and the engine will start. As soon
as the engine starts release the toggle switch and it will
return to the run position. If the engine does not start after
15 seconds release the switch and let the starter rest for
15 seconds and reattempt to start. If the unit still will not
start, consult the troubleshooting guide in the back of this
manual.
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 A.T.S.
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 one half of the line to line
voltage.
** Notice **
If for any reason during the check out procedure the
voltage and frequency are not correct, move the toggle
switch to the “STOP” position and correct the trouble
before proceeding.
After verifying the voltage and frequency are correct,
move the left hand toggle switch to the auto position. The
unit should shut off with no time delay. The left hand
toggle switch must be left in the AUTO position for
proper operation of the generator. If you leave it in the
run position the fuel solenoid will remain open and it will
not shutdown properly after the next exercise period.
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.
1. Move the right hand toggle switch from the stop
position to the normal position. The alarm light should
go out. The unit is now ready to be operated from the
Automatic Transfer Switch.
