Stopping
Normal Stopping
1. Disconnect load from generator set and allow it to
run without load for 5 minutes.
NOTE
Run the generator at no load for 5 minutes prior to
stopping to ensure adequate cooling of the set.
2. Move generator master switch to the OFF/RESET
position. Engine will stop.
NOTE
If engine stop is signaled by a remote switch or
automatic transfer switch, the generator set will
continue running during a 5-minute cooldown cycle.
Emergency Stopping
Turn generator master switch to the OFF/RESET
position or activate controller emergency stop switch (if
equipped) or optional remote emergency stop for
immediate shutdown. If either emergency stop switch is
activated, the controller low water temperature/auxiliary
lamp will light and the unit will shut down. On 200-1600
kW models with Detroit Diesel engines, both the air
damper and low water temperature/auxiliary lamps will
light if the emergency stop switch is activated.
NOTE
Use the emergency stop switch(es) for emergency
shutdowns only. Use the generator master switch to
stop the generator set under normal circumstances.
Resetting Emergency Stop
Switches
Use the following procedure to restart the generator set
after shutdown by emergency stop switch (local or
remote). Refer to Controller Resetting Procedure later
in this section to restart the generator set following a
fault shutdown.
1. Investigate cause of emergency stop and correct
problem(s).
2. If remote emergency stop switch was activated,
reset switch by replacing glass piece. If
controller-mounted emergency stop switch was
activated (if equipped), reset controller emergency
stop switch by rotating switch clockwise until switch
springs back to original position.
NOTE
The controller auxiliary lamp will light if the
generator master switch is in the RUN or AUTO
position during the resetting procedure.
3. If controller air damper light is on, reset air damper
on engine by rotating air damper lever as shown in
Figure 2-6 and the air damper light will go out.
(Used on 200-1600 kW models with Detroit Diesel
engines only).
4. Toggle generator master switch to OFF/RESET
and then to RUN or AUTO to resume operation.
The generator set will not crank until the resetting
procedure is completed.
