Starting CYCLE-SENTRY Equipped Units
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 com-
modity, ambient temperatures and trailer insulation. How-
ever, not all temperature controlled products can be properly
transported using CYCLE-SENTRY operation. Certain
highly sensitive products normally require continuous air
circulation.
Since highly sensitive products will normally require con-
tinuous air circulation, CYCLE-SENTRY units come
equipped with a selector switch for CYCLE-SENTRY or
Continuous Run operation.
Select the operation mode for proper protection of your par-
ticular commodity using 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
Examples of Products Normally 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 rec-
ommended temperature)
• Fresh flowers and foliage
The above listings are not all inclusive. Consult your grower
or shipper if you have any questions about the operating
mode selection of your type of load.
Continuous Run Operation
With the selector switch in the Continuous Run position, the
CYCLE-SENTRY unit will operate in its regular cooling
and heating modes. Refer to Starting Instructions for stan-
dard units.
Automatic Start (CYCLE-SENTRY Operation)
With the selector switch placed in the CYCLE-SENTRY
position, the CYCLE-SENTRY system shuts down the unit
when the trailer temperature reaches the setpoint, and
restarts the unit on microprocessor demand. Start-ups may
also be initiated by defrost cycle initiation, low battery volt-
age, or engine coolant temperature demand.
If defrost is initiated manually, the unit will start and run on
low speed. When the defrost cycle is complete, the unit will
run in the operating mode called for by the microprocessor.
In cold ambients, the CYCLE-SENTRY system automati-
cally maintains engine temperature by restarting the unit if
the engine coolant temperature drops to -1° C (30° F). When
the unit starts up because of low engine coolant temperature,
the unit will run in whichever operating mode the unit
microprocessor calls for until the battery is fully charged and
the engine block temperature rises to 32° C (90° F).
