OPM-160/A
approximate voltage should be found between terminals
G3 and G-N (120 volts AC).
On three phase panels the G2 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. Also on three
phase systems make sure that the rotation is the same on
the generator as it is on your line power. Failure to insure
proper rotation will cause three phase motors to spin
backwards possibly damaging them.
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.
4. 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 mode.
To test the Automatic Transfer Switch, follow the instruction
on the operator’s manual that came with the transfer
switch. If you get a fault during the initial start up or prior
to start up, it is most likely a false warning light. Simply reset
the ATS start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in the standby mode,unless
servicing the unit. For standby operation, press the AUTO
button on the front of the control. The green light should
light up next to the AUTO button.
NOTE: For setting the exerciser circuit, for all ATS, see the
operator’s manual shipped with the ATS.
