Automatic Shutdown

This unit is equipped with a low oil pressure and high
coolant temperature automatic shutdown system. This
system will automatically shut off the fuel supply to stop
the engine if oil pressure drops too low or the engine
exceeds normal operating temperature. Return the
Control Power switch to the STOP position to reset the
unit after the cause of shutdown has been determined.

Emergency Stop

CAUTION
Equipment Damage. The emergency stop switch is
not to be used to power down the unit under normal
operating circumstances. Doing so will result in
equipment damage.
See Figure 3-8. The unit is equipped with one
emergency stop button, clearly labeled "EMERGENCY
STOP." The button can be accessed and activated with
all doors closed and locked.
Activate the emergency stop button by pushing it in until
it locks down. This trips the main circuit breaker, which
will open the contact and disconnect the load to the
connection lugs. An emergency stop also opens the fuel
circuit, shutting down the engine. The emergency stop
fault will be displayed on the control panel.
Figure 3-8. Emergency Stop Switch
The emergency stop button will remain locked until it is
pulled out.
