Unit Description
26
The CYCLE-SENTRY system automatically
starts the unit on microprocessor demand, and
shuts down the unit when all demands are
satisfied. As well as maintaining the box
temperature, engine block temperature and battery
charge levels are monitored and maintained. If the
block temperature falls below 30 F (-1 C), the
engine will start and run until the block
temperature is above 90 F (32 C). If the battery
voltage falls to the programmed limit selected by
CYCLE-SENTRY Battery Voltage (typically 12.2
volts) and Diesel CYCLE-SENTRY mode is
selected, the engine will start and run until the
charge rate falls below that programmed by
CYCLE-SENTRY Amps (typically 5 amperes).
Features of the CYCLE-SENTRY system are:
• Offers either CYCLE-SENTRY or
Continuous Run operation.
• Controller regulated all season temperature
control.
• Maintains minimum engine temperature in
low ambient conditions.
• Battery Sentry keeps batteries fully charged
during unit operation.
• Variable preheat time.
• Preheat indicator buzzer.
Data Logging
Trip data is logged and retrieved as follows:
ServiceWatch™:
ServiceWatch™ is standard
equipment. It is an integrated data logging system
that records operating events, alarm codes and
compartment temperatures as they occur and at
preset intervals.
CargoWatch™:
CargoWatch™ is an optional
datalogger systems that logs data of up to six
temperature sensor/probes, four door switches,
humidity sensor, data averaging and
programmable, temperature out of range alarms.
The data can be retrieved using an IBM ® PC
compatible laptop or desktop computer and
Thermo King WinTrac 4.4 (or higher) software.
The computer is connected to the Cargo Watch
Port on the front of the control box. Detailed
graph or table trip reports can then be created.
If optional temperature sensors are installed, a
directly connected printer can be used to print a
report of the sensor readings. The printer is
connected to the Service Watch Port.
Standard and Optional
Temperature/Data Management
Systems
OptiSet™:
Optiset™ allows an entire fleet to be
configured to match customers’ needs (up to 10
preset conditions). OptiSet™ is standard
equipment. Refer to TK 51587 SR-2
Microprocessor Control System Diagnostic
Manual for configuration instructions.
FreshSet™:
FreshSet™ is a demand base
temperature control for fresh products. FreshSet™
modifies and adjusts unit airflow operation to
control temperature and to maximize protection of
cargo, while keeping operating costs to a
minimum. FreshSet™ is standard equipment.
Refer to TK51587 SR-2 Microprocessor Control
System Diagnostic Manual for configuration
instructions.
FleetWatch™:
FleetWatch™ is an optional
software package designed to allow the fleet
manager to retrieve, categorize and analyze
collected information and schedule maintenance.
Sequence of Operation
When the Microprocessor On/Off switch is turned
on and Controller
O
N
key is pressed, the LCD
display is illuminated and shows the setpoint and
the return air temperature. If the
CYCLE-SENTRY mode has been selected, the
unit will start and stop automatically. If the
Continuous mode has been selected, the unit will
start and run automatically.
Your Thermo King unit provides a wide
range of control and programming
flexibility. However, pre-programming of
the unit controller may prohibit operation
in certain temperature ranges within some
modes and may also prohibit certain
modes of operation. If you have controller
programming questions, contact your
supervisor before requesting service.
