2.3.2 Stopping (User Stopping and
Fault Shutdown)
Normal Stopping
Run the generator set without load for 5 minutes to
ensure adequate engine cooldown.
The controller has a programmable cooldown timer that
functions only when the master switch is in the AUTO
position. To stop the generator set, place the generator
set master switch in the OFF/RESET position and wait
until the generator set comes to a complete stop.
Note: The cooldown cycle times out before the
generator set stops when a remote switch or
automatic transfer switch initiates the generator
set start/stop sequence.
Emergency Stopping
Use the controller emergency stop switch or optional
remote emergency stop for immediate shutdown.
The emergency stop switch bypasses the time delay
engine cooldown and immediately shuts down the
generator set.
Note: Use the emergency stop switch(es) for
emergency shutdowns only. Use the generator
set master switch for normal shutdowns.
The controller system shutdown lamp lights and the unit
shuts down when the local or remote emergency stop
switch activates.
Battle Switch/Fault Shutdown Override
Switch
The battle switch function forces the system to ignore
normal fault shutdowns such as low oil pressure and
high engine temperature. The battle switch does not
override the emergency stop and overspeed shutdown.
When the battle switch function is enabled the generator
set continues to run regardless of shutdown signals
where potential engine/alternator damage can occur.
When this input is enabled the yellow warning lamp
illuminates and stored warning/shutdown events that
are ignored continue to log in Menu 5— Event History.
See Section 2.8.9, Menu 9—Input Setup, for information
on how to enable the battle switch feature.
Cooldown Temperature Override Function. This
feature provides the ability to bypass (override) the
generator set’s smart cooldown temperature shutdown
and force the generator set to run for the full engine
cooldown time delay.
See Section 2.8.8, Menu 8—Time Delays, for
information on how to enable the cooldown temperature
override feature.
2.3.3 Emergency Stop Switch Resetting
Use the following procedure to reset the generator set
after shutdown by a local or remote emergency stop
switch. Refer to Section 2.3.7, Controller Reset
Procedure, to restart the generator set following a fault
shutdown.
1. Place the generator set master switch in the
OFF/RESET position.
2. Investigate and correct the cause of the emergency
stop.
3. Reset the optional remote emergency stop switch by
replacing the glass piece, when equipped. Additional
glass rods are available as a service part. Reset the
controller emergency stop switch by pulling the
switch knob outward.
4. After resetting all faults using the controller reset
procedure in Section 2.3.7, toggle the generator
set master switch to RUN or AUTO to restart the
generator set. The generator set will not crank until
the reset procedure completes.
2.3.4 Status Lamps
System Ready. The green lamp illuminates when the
generator set master switch is in the AUTO position and
the system has no fault conditions.
Not in Auto. The yellow lamp illuminates when the
generator set master switch is not in the AUTO position.
See Master (Switch) Not in Auto in 2.3.5 System
Warning Lamp.
2.3.5 System Warning Lamp
The yellow warning lamp illuminates indicating a fault or
status event but does not shut down the generator set
under the following conditions. In some cases the alarm
horn also sounds. See Section 2.3.7, Controller Reset
Procedure, for instructions on resetting a system
warning.
When the system warning lamp is on and no message
displays, press the Reset Menu and the menu down
key to view messages. When the system warning
continues, it may lead to a fault and cause a system
shutdown.
Use the Alarm Off keypad switch to silence the alarm
horn at the operator’s discretion. Place the generator
set master switch in the AUTO position before silencing
the alarm horn. The alarm horn cannot be silenced
unless the master switch is in the AUTO position.
