Starting the Diesel Engine
Diesel engine preheats and starts automatically in
both Continuous Mode and CYCLE-SENTRY
mode. The engine will preheat and start if
necessary when the unit is turned on. The engine
preheat and start will be delayed in
CYCLE-SENTRY mode if there is no current
need for the engine to run. If a key or sequence of
keys are pressed on the controller before the
engine starts, the engine will preheat and start
approximately 10 seconds after pressing the last
key.
See “Turning Unit On” on page 39.
NOTE: Run a pretrip test if the unit has not been
used recently. See “Pretrip Tests” on page 60.
Unit Fails To Start
If the engine fails to start within 15 seconds, take
the following steps.
1. Check for and correct any alarm conditions.
See “Viewing and Clearing Alarms Screen
Sequence” on page 52.
2. Clear all alarms. See “Viewing and Clearing
Alarms Screen Sequence” on page 52.
3. Press the
O
FF
key to tun the unit off.
4. Press the
O
N
key to turn the unit on.
5. The controller will go through the start up
screens and then after a 10 second delay the
unit will start automatically.
6. If the engine will still not start, turn the unit
off. Determine and correct the cause for not
starting.
7. Repeat the procedure.
After Start Inspection
After the unit is running, check the following
items to confirm that the unit is running properly.
Oil Pressure:
Check the engine oil pressure by
pressing the
G
AUGES
soft key. See “Viewing Gauge
Readings” on page 47. The Engine Oil Pressure
Display should indicate OK not LOW.
Ammeter:
Check the ammeter reading by pressing
the
G
AUGES
soft key. See “Viewing Gauge
Readings” on page 47. The Amps Display should
indicate a positive charge amperage rate to the
battery. A negative (-) number indicates a
discharge condition.
Compressor Oil:
The compressor oil level should
be visible in the compressor sight glass after 15
minutes of operation.
Pre-Cooling:
Make sure that the setpoint is at the
desired temperature. See “Changing the Setpoint”
on page 43. Allow the unit to run for a minimum
of 30 minutes (longer if possible) before loading
the trailer.
This provides a good test of the refrigeration
system while removing residual heat and the
moisture from the trailer interior to prepare it for a
refrigerated load.
Defrost:
When the unit has finished pre-cooling
the trailer interior, manually initiate a Defrost
cycle. See “Initiating a Manual Defrost Cycle” on
page 46. This will remove the frost that builds up
while running the unit to pre-cool the trailer.
CAUTION: The engine may start
automatically any time the unit is turned
on.
WARNING: Never use starting fluid.
