7. With the engine running smoothly check the no load
voltage and frequency on the digital display. The voltage
should be 240AC 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. The
voltage between the L1and L2 terminals should be the
same as it was on the generator front panel. The voltage
should also be checked between the hot terminals (L1, L2)
and the N to be certain of a balanced voltage output and a
solid neutral connection.
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.
8. Stopping - In manual mode, pressing the STOP/RESET
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. Pressing the STOP/RESET button a second
time will shut down immediately.
In the event of an emergency, the E-Stop can be pushed.
WARNING: EQUIPMENT DAMAGE
Stopping the generator without sufficient cool-down
time, can result in premature wear and cause damage
to engine components. The EStop and override
shutdowns should only be used in the event of an
emergency.
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 and 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.
CONNECTING THE LOADS
WARNING
All wiring must be done in accordance with National
Electric Code NFPA 70.
There are two ways the loads may be connected to the
1. Receptacle Panel -
A variety of receptacles have been provided for your
convenience .
2. Full Power Load Connection Terminal Block -
For remote connections and connecting load distribution
boxes, heavy duty terminal blocks have been provided.
These terminal blocks are located on the rear of the unit
The neutral and ground are connected together
at this panel. For use with an isolated neutral, remove the
jumper strap between the neutral connection block and
the ground lug. This will isolate the neutral from the
ground and allow you a single point grounding at a
distribution panel. When using these terminal blocks,
be sure to use wire rated large enough to carry your full
load or the full rated load of the generator.
CONTROL POWER
The ComAp controller consumes small amounts of battery
power when it is in use. The controller comes with a power
switch that disconnects battery power when it is not in use.
The switch is designed with a safety relay that prevents it
from removing power to the controller while the generator
is operating. If the switch is turned off while the engine is
running it will continue operating until the engine shuts
down and then the controller will power down.
This switch should be used when the generator is not
going to be used over the course of several days and the
generator is not connected to a battery charger.
SHUTDOWN ALARMS
Emergency Stop -
The emergency stop was activated
Overspeed -
This is active if the speed is greater than
120% of nominal engine RPM
Underspeed -
Low engine RPM
Low Oil Pressure -
The engine will shut down when oil
pressure drops below preset threshold
High Coolant Temperature -
The engine will shut down when the
coolant temperature exceeds the preset
threshold
