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 check list to verify correct installa-
tion before starting the engine:
1 Engine oil.* Check level & fill as required with
proper grade/qty.
2 Engine coolant.* Check level & fill as required
with proper mixture.
3 Unit mounting base properly bolted down.
4 Clearance for service and maintenance on all
sides.
5 Proper fuel line material, and size.
6 All fuel line connections tight.
7 Fuel line protected and a moisture trap installed
(may be required for N.G.).
8 LP/NG pressure O.K. 4-6 Oz. (7-11" WC).
9 Battery connections clean and tight.
10 Battery fully charged.
11 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
1. 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.
2. With the engine running smooth, check the no load
voltage and frequency at terminals G1 and G3 on the
generator terminal block in the A.T.S. The voltage
between G1 and G3 should be between 240 and 262
volts A.C. and a frequency of 61.5 To 62 hertz (Hz) on
the PSS8 & PSS12. The frequency on the PSS20
should be 60.0 to 60.5 hertz. The voltage should also
be checked between the hot terminals (G1 and G3)
and the G-N to be certain of a balanced voltage output
and a solid neutral connection. The voltage between
G1 and G-N should be about one half of the line to line
(G1 to G3) voltage or approximately 120 to 132 volts
AC. The same approximate voltage should be found
between terminals G3 and G-N (120 to 132 volts AC).
** 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.
Move the selector switch on the engine generator set to
the “AUTOMATIC” position. Next move the selector
switch on the A.T.S. panel to the “START” position.
The unit will go into a 10 second start delay and then
start up. If it fails to start at this time, the DC inter
connection wiring is incorrect. When the selector
switch on the A.T.S. is moved to the “DISABLE”
position the unit will go into a cool down period and
then shut off. The cool down period for the PSS8 &
PSS12 is 90 seconds on the PSS20 it is 3 minutes. As
long as line power is still applied to the transfer switch
during this test period the A.T.S. will not transfer the
load to the generator.
Next you need to test the complete system. To accom-
plish this you will have to fail the incoming line power
to the A.T.S. panel. First move both selector switches
to the automatic position. Then fail the incoming
power. All the loads connected to the A.T.S. should
now be dead. The engine generator set will go into a
10 second start delay. At the end of the start delay the
unit will start up. A soon as the engine generator set
reaches operating speed the generator side contactor
will close and the load will be applied to the engine
generator.
Restoring the line power will cause the generator side
contactor in the A.T.S. to open. The line side contactor
will close as soon as the generator side contactor
clears the mechanical interlock and closes the
electrical interlock. These interlocks ensure that you
get a clean ‘break before make’ action in the transfer
switch.
The restoration of line power also sends a stop signal to
the engine generator set. This stop signal will activate
a cool down timer circuit. The engine generator will
shut down 90 seconds later on the PSS8000 &
PSS12000, 3 minutes later on the PSS20000.
This completes your installation and unit testing. AL-
WAYS leave the system in automatic mode unless
servicing the unit. For automatic operation, keep both
the generator set and transfer selector switches in the
“AUTOMATIC” position.
