Restarting Unit
This procedure is used when starting units that have been
shut off for short periods of time. When a unit that has been
shut off for a long period of time is first started, it should be
started and put through a pretrip.
1. Place the On-Off switch in the ON position.
2. After a 10 second delay, the unit should preheat and
start automatically.
NOTE: When the CYCLE-SENTRY Icon is active, the
unit may not start if: the compartment temperature is
near the setpoint, the engine is warm, and the battery
is fully charged.
If cooling or heating is required and the engine temperature
is below approximately 90 F (32 C), but the engine fails to
start automatically:
• Turn the On-Off switch to the OFF position.
• Check for and correct any alarm conditions and clear
the alarm codes. View the alarms with the CODE key,
clear the alarms with the CLEAR key, and then repeat
the auto start procedure. Refer to the appropriate Oper-
ation and Diagnosis Manual for detailed information
about alarms.
• If the engine will still not start, turn the On-Off switch
to the OFF position, determine and correct the cause of
the failure.
After Start Inspection
After the unit is running, the following items can be quickly
checked to confirm that the unit is running properly.
1. OIL PRESSURE. Check the engine oil pressure in high
speed by pressing the OIL PRESS key. The oil pressure
should read OK, not LOW.
When first starting a cold engine, the oil pressure may
be higher.
2. AMMETER. Check the ammeter reading by pressing
the AMPS key. The ammeter should indicate normal
battery charging current. It may be fairly high right
after starting the unit, but should taper off as the battery
is recharged.
