GENERATOR CONTROL PANEL
— This switch controls the
running of the unit. If this switch is set to the
position, the unit will not run. When this switch is set to the
manual position, the generator will start immediately.
If the generator is to be connected to a building’s AC
power source via a transfer switch (isolation), place the
switch in the AUTO position. In this position, should an
outage occur, the automatic transfer switch (ATS) will
start the generator automatically via the generator’s auto-
start contacts conn ected to the ATS’s start contacts.
Please refer to your ATS installation manual for further
instructions for the correct installation of the auto-start
contacts of the geerator to the ATS.
— Indicates the engine pressure
has fallen below a safe operating level. The oil pressure
is detected using variable resistive values from the
oil pressure sending unit. This is considered a major
fault.
High Coolant Temperature — Indicates the engine
temperature has exceeded a safe operating level. The
engine temperature is detected using variable resistive
values from the temperature sending unit. This is
considered a major fault.
— Indicates the unit has
attempted to start a pre- programmed number of
timesand has failed to start. The number of cycles and
duration are programmable. It is pre-set at 3 cycles with
a 10-second duration. This is considered a major fault.
— Indicates the engine is running
at an unsafe speed. This is considered a major fault.
— Indicates that engine is running at
a safe operating speed.
Located behind the generator control panel is the
. This box contains some of the
necessary electronic components required to make the
generator function.
The is equipped with the following major
components:
Over-Current Relay
Voltage Rectifier (AVR)
Starter Relay
Current Transformer
Voltage Change-Over Board
Three Phase Circuit Breaker
NOTICE
Remember the overcurrent relay monitors the current
flowing from the
to the load.
In the event of a short circuit or over current condition,
it will automatically trip the 800 amp main breaker.
To restore power to the , press
the reset button on the overcurrent relay and place the
main circuit breaker in the closed position ().
