OPTIONS

Light Bar

The Light Bar is an external indicator light which can be
seen in the driver’s rear view mirror from the cab of the
tractor. The green LED indicates “STATUS OK”. The
amber LED indicates “CHECK UNIT”. The amber light
is illuminated when the control system illuminates the
alarm light. Alarms can be read on the display.
For units with EES installed, the amber light will also be
illuminated when the EES System is in Service Mode.
This does not affect unit operation.

When placed in the START/
RUN position, this switch pro-
vides power to start the unit.
The main microprocessor per-
forms a self-test. Then set-
point and compartment
temperatures are displayed.
