c. Enter the new setpoint by pressing the
E
NTER
key within 5 seconds.
3. Initiate a Pretrip Test (refer to the appropriate
Operator’s Manual or Microprocessor
Diagnosis Manual for detailed information
about the pretrip). This procedure is automatic
and can be performed on the way to the
loading area or while waiting to load.
a. Place all the On/Off switches in the On
position.
b. Clear any alarms.
c. Press and hold the

PRE LOAD will appear on the display
and the pretrip test will start.
•
PRE AMPS will appear on the display
indicating that the amps check is
running and the pretrip has started.
•
The amps check will continue for
several minutes, then the unit will start
automatically and the operational tests
will be performed.
4. When the Pretrip Test is complete, PASS,
CHECK, or FAIL will appear on the display
until a function key (e.g.,
S
ELECT
or
E
NTER
) is
pressed. Continue as follows:
•
PASS—The unit is running and no alarms
have been recorded. The unit has passed
the pretrip. Go to step 6.
•
CHECK—The unit is running but Check
Alarms have been recorded. Go to step 5.
•
FAIL—The unit has shut down, recorded
Alarm Code 28, and possibly recorded
other Shutdown Alarms. Go to step 5.

7. Complete the “After Start Inspection” on
Selection of Operating Modes
The Thermo King CYCLE-SENTRY system is
designed to save refrigeration fuel costs. The
savings vary with the commodity, ambient
temperatures and trailer insulation. However, not
all temperature controlled products can be
properly transported using CYCLE-SENTRY
operation. Certain highly sensitive products
normally require continuous air circulation.
The microprocessor has a CYCLS screen, which
is used to select CYCLE-SENTRY (CYCLS
YES) or Continuous Run (CYCLS No) operation.
Refer to the appropriate Operator’s Manual or
Microprocessor Diagnosis Manual for more
information about CYCLE-SENTRY selection.
Your selection of the operating mode for the
proper protection of a particular commodity
should use the following guidelines:
Examples of Products Normally
Acceptable for CYCLE-SENTRY Operation
•
Frozen foods (in adequately insulated trailers)
•
Boxed or processed meats
•
Poultry
•
Fish
•
Dairy products
•
Candy
•
Chemicals
•
Film
•
All non-edible products
