After completing the above checklist, the engine-
generator 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 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 235-245 volts.
The frequency should be between 60.0 to 60.5 hertz. The
voltage should also be checked between the hot termi-
nals (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.
** 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. For Non-UL Winco Automatic
Transfer Switches follow the instruction below. For All UL
Transfer Switches follow the instruction in the operators
manual you received with your transfer switch. For the
UL A.T.S. if you get a fault light during the initial start up or
prior to start up it is most likely a false warning light.
Simply reset the A.T.S. and start over.
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, check
your DC inter connection wiring. 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 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 genera-
tor.
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. As 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 inter-
lock. 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 3 minutes later.
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.
