Start/Stop Procedure; Stopping - Kohler 6.5RMY Operation Manual

Start/Stop Procedure

Local Starting
Place the generator set master switch in the RUN
position to start the generator set at the controller.
NOTE
The alarm horn sounds whenever the generator set
master switch is not in the AUTO position.
NOTE
The microprocessor controller is equipped with a
transient start/stop function to avoid accidental cranking
of the rotating engine. If the generator set master switch
is momentarily placed in the OFF/RESET position then
quickly returned to RUN, the genset slows to 249 rpm
and recranks before returning to rated speed.
NOTE
The microprocessor controller is equipped with an
automatic restart function. The generator set attempts
to restart if the engine speed drops below 13 Hz
(390 rpm). Failure to correct the cause of the decreased
engine speed results in an overcrank condition.
Auto (Remote) Starting
Place the generator set master switch to the AUTO
position for start-up by automatic transfer switch or
remote start/stop switch (connected to controller
terminals TB1-3 and TB1-4).
Crank Mode Selection
The microprocessor controller provides up to 45
seconds of continuous cranking or 75 seconds of cyclic
cranking (crank 15 seconds, rest 15 seconds, crank 15
seconds, etc.) before overcrank shutdown. Make the
cranking mode (cyclic or continuous) selection on the
2-6 Operation
controller circuit board terminal strip. For cyclic
cranking, leave circuit board terminal TB1-9 open. Run
a jumper between circuit board terminal TB1-2 (ground)
and terminal TB1-9 for continuous cranking.

Stopping

Normal Stopping
1. Disconnect load from generator set and allow it to
run without load for 5 minutes.
NOTE
Run the generator set at no load for 5 minutes prior
to stopping to ensure adequate cooling of the set.
2. Place the generator set master switch in the
OFF/RESET position. The engine stops.
NOTE
The generator set runs for a 5-minute cooldown
cycle if engine stop is signaled by a remote switch
or automatic transfer switch.
Emergency Stopping
Place the generator set master switch in the
OFF/RESET position or activate remote emergency
stop (if equipped) for immediate shutdown. The
controller AUXILIARY lamp lights and the generator set
shuts down if the emergency stop switch is activated.
The remote annunciator and/or audio-visual alarms, if
equipped, signal an emergency stop.
NOTE
Use the emergency stop switch(s) for emergency
shutdowns only. Use the generator set master switch to
stop the generator set under normal operating
conditions.
