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, G2and G3 on the
generator terminal block in the A.T.S. The frequency
should be between 61.5 to 62 hertz (Hz). The voltage
should also be checked between the hot terminals (G1,
G2 and G3) and the G-N to be certain of a balanced
voltage output and a solid neutral connection. Your
actual voltage reading will depend on what voltage
generator you have ordered. Check the generator name
plate for correct voltage if you are uncertian.
** 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 differnet procedure. Remeber 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. As remeber 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. tell 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 system will go into a start
delay, this start delay will vary depending on the transfer
switch you have installed. The engine control on the
generator set wil give you a 10 second start delay in
addition to what every delay in in you transfer switch. At
the end of the start delay the unit will start up. Once the
engine generator set reaches operating speed the transfer
switch will transfer the load to the engine generator.
Restoring the line power will allow the transfer switch to
return the load to line power. Differnt transfer switches
may have differnt retansfer time delay setting.
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.
This completes your installation and unit testing.
ALWAYS leave the system in automatic mode unless
servicing the unit. For automatic operation, keep the
generator set and transfer switch selector switch (if you
have one) in the “AUTOMATIC” position.
