4.3 Block Heaters
Block heaters are available as loose accessories. Use
block heaters on standby applications where the
generator set is frequently subjected to temperatures
below 0_C (32_F). The engine block heater kit heats the
engine coolant, making starting easier and warmup
quicker. The thermostat, built into the base of the block
heater, automatically turns off the heater when coolant
temperature reaches 27 to 38_C (80 to 100_F).
Connect the block heater to a power circuit that is
backed up by the generator set to provide power at all
times.
Note: Block heater damage. The block heater will fail
if the energized heater element is not immersed
in coolant. Fill the cooling system before turning
on the block heater. Run the engine until it is
warm and refill the radiator to purge the air from
the system before energizing the block heater.

4.4 Emergency Stop Kits
The emergency stop (E-stop) switch allows immediate
shutdown of the generator set from a remote location.
The E-stop assembly includes a shroud that allows the
installation of a lockout/ tagout device to lock the switch
in the stop position. See Figure 4-3.
Emergency stop kits are available for mounting on the
generator set enclosure and for remote mounting.
Multiple switches may be connected in series to ensure
that activating any one of the stop switches will stop the
generator set.
Operation
Press the red STOP button to shut down the generator
set in an emergency. Using the emergency stop button
bypasses the engine cooldown cycle, stopping the
engine immediately. The controller displays and
emergency stop shutdown message and the unit shuts
down. The generator set cannot be restarted until the
emergency stop switch(es) is/are reset.
Lockout/Tagout
The emergency stop button can be locked in the STOP
position. Insert a lock through two openings in the yellow
shroud to prevent the stop button from being pulled out.
Remove the lock for normal operation. A lock is not
required in order to keep the switch activated. The
switch button will stay depressed until it is pulled out by
the operator.
Resetting the Emergency Stop Switch
To reset the E- stop switch, remove the locking device
and pull the button out. Reset the controller by pressing
1
the OFF/RESET button.
