Starting Unit (Full Unit Self Check)
The procedure is used for a complete checkout of
the unit, and unit control circuits. It should be
used when first starting the unit for a trip before
the cargo is loaded. A full Unit Self Check
procedure may take up to 30 minutes and the unit
will run unattended.
1. Perform a Pretrip Inspection.
2. Adjust the setpoint to the desired load
temperature (see the Operation Manual or the
µ
P-T Microprocessor Diagnosis Manual, for
detailed information about adjusting the
setpoint).
a. Change the setpoint display with the
A
RROW
keys.
b. Enter the new setpoint by pressing the
E
NTER
key within 5 seconds.
3. Initiate a Unit Self Check (see the Operation
Manual or the
µ
P-T Microprocessor
Diagnosis Manual, for detailed information
about the Unit Self Check). This procedure is
automatic and can be performed on the way to
the loading area or while waiting to load.
a. Press the
O
N
key.
b. Clear any alarms.
c. Press and hold the
T/K

seconds until the Unit Self Check [USC]
prompt screen appears.
d. Press the
E

briefly show [Lod] (load) and the unit will
then start the Unit Self Check.
4. When the pretrip test is complete; [PASS],
[CHECK], or [FAIL] will appear on the
display until any key on the control panel is
pressed. Continue as follows:
[PASS] (Unit running, no alarms)
•
Unit has passed the pretrip, go to step 5.
[CHECK] (Unit running but Check Alarms
have been recorded)
or
[FAIL] (Unit has shut down and recorded
Shutdown Alarms)
a. View the alarms with the
S
ELECT
key (see
the appropriate Operation and Diagnosis
Manual for detailed information about
alarms).
b. Correct the alarm conditions.
c. Clear the alarms with the
C
LEAR
key (see
the
µ
P-T Microprocessor Diagnosis
Manual, for detailed information about
alarms).

unit passes the unit self check).
5. Recheck the setpoint.
6. Complete the After Start Inspection.
Selection of Operating Modes on
CYCLE-SENTRY Equipped Units
The Thermo King CYCLE-SENTRY system is
designed to save refrigeration fuel costs. The
savings vary with the commodity, ambient
temperatures and trailer insulation.
CYCLE-SENTRY is designed for use only with
products which do not require tight temperature
control or continuous airflow, such as all deep
frozen products and non-perishable non-frozen
products.
The start/stop nature of CYCLE-SENTRY does
not satisfy the temperature control or airflow
requirements for perishable or temperature
sensitive products. Thermo King therefore does
NOT recommend the use of CYCLE-SENTRY
control for these products.
Your selection of the operating mode for the
proper protection of a particular commodity
should use the following guidelines:
Products Requiring Continuous Run
Operation for Air Flow
•
Fresh fruits and vegetables, especially
asparagus, bananas, broccoli, carrots,
citrus, green peas, lettuce, peaches,
spinach, strawberries, sweet corn, etc.
•
Non-processed meat products (unless
pre-cooled to recommended temperature)
•
Fresh flowers and foliage.
