4. During manual operation the load will not normally be applied
to the generator. But caution must be used, if the line power
should fail or be turned off to the transfer switch during manual
operation the load may be applied to the generator.
With the engine running smoothly check the no load voltage
and frequency on the digital display. The voltage should be
08/40/480 AC depending on which model you have and a
frequency of 59.5 To 60.5 hertz (Hz).
If you have the proper voltage at the generator the next step is
to check the voltage at the generator terminals in the Automatic
Transfer Switch. The voltage between the G1 and the G3
terminals should be the same as it was on the generator front
panel. 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 10 volts AC (77 on 480
units). The same approximate voltage should be found between
terminals G3 and G-N (120 volts AC).
On three phase panels the G voltage level should also be
checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU
KNOW WHERE THE HIGH VOLTAGE “WILD” LEG IS. IT MUST
BE IN THE SAME LOCATION ON THE LINE SIDE AS IT IS ON
THE GENERATOR SIDE. (i.e. if it’s on L-3 on the line side it
must be on G-3 on the generator side.
** Notice **
If for any reason during the check out procedure the voltage and
frequency are not correct, depress the STOP/RESET button and
correct the trouble before proceeding.
5. Stopping – There are two ways to stop the unit when it is in
the manual mode. Pressing the STOP/RESET button will stop
the unit immediately. Pressing the AUTO mode button will stop
the unit but only after the cool down timers have timed out and
there is no remote start signal being sent to the unit.
AUTO MODE
To activate the automatic start mode you will just need to
depress the AUTO button, the LED indicator beside the button
confirms that the unit is in automatic start mode.
To test the automatic start Transfer Switches follow the
instruction in the operator’s manual you received with your
transfer switch. 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 ATS and start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in standby mode unless servicing the
unit. For standby operation, press the AUTO button on the front
of the engine control. The green light should light up next the
AUTO button.
SETTING THE EXERCISER CIRCUIT
For all ATS see the instruction manual shipped with the ATS for
instruction on setting the exercise circuit in your ATS
