PROCEDURE
Engine Generator Set only
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 G1 and G3 on the
generator terminal block in the A.T.S. The voltage
between G1 and G3 should be between 240 +/- 5 volts.
The frequency should be between 61.5 to 62 hertz (Hz).
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 +/- 3 volts AC. The same approximate voltage should
be found between terminals G3 and G-N.
** 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 toggle switch to the “AUTO” position and
follow the instructions in the manual you received with the
transfer switch for initial start up and testing. Each of the
transfer switches has a different procedure. Remember
the unit will go into a short time delay before starting after
it receives the start signal from the transfer switch.
If it fails to start at this time, check your DC interconnec-
tion wiring. 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. Remember that there is
a 90 second cooldown delay built into the engine control,
so the unit will run during this period after the A.T.S. tells it
to stop.
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. All the loads connected to the A.T.S.
should now be dead. The engine generator set will go
into a 3 to 10 second start delay. At the end of the start
delay the unit will start up. As soon as the engine
generator set reaches operating speed the transfer switch
will transfer the load to the engine generator on the Winco
Non-UL switches on the UL switches there is a short
delay before it transfers.
Restoring the line power will allow the transfer switch to
return the load to line power.
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. The UL switches will have an
additional cool down delay built into the switch of as long
as 5 minutes.
This completes your installation and unit testing.
ALWAYS 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.
