Unit Description
30
Microprocessor Power Switch
The Microprocessor Power switch applies 12 Vdc
control power to the microprocessor and must be
On to operate the unit. It is located on the roadside
of unit, lower left corner.
NOTE: When the Microprocessor Power Switch
is turned to the Off position, power is still applied
to the Interface Board and control circuits. To
completely remove power from the control
system, disconnect the unit battery.

CYCLE-SENTRY Start/Stop
System
A CYCLE-SENTRY Start-Stop fuel saving
system provides optimum operating economy.
The CYCLE-SENTRY system automatically
starts the unit on microprocessor demand and
shuts down the unit when all demands are
satisfied.
The system monitors and maintains the
compartment temperature, the engine block
temperature, and battery charge levels at a point
where quick, easy starts are possible.
Defrost
Frost will gradually build up on the remote
evaporator coils as a result of normal operation.
Periodically this frost must be melted to prevent a
loss of cooling and airflow.
Defrost is accomplished by passing hot refrigerant
gas through the affected evaporator coil, thus
melting the frost (or ice). Melted frost drains out
of the unit onto the ground through the drain
tubes.
Defrost can be initiated at any time the evaporator
coil temperature is below 45 F (7 C).
Only one zone can be in defrost at a time.
There are three methods of defrost initiation:
1. The microprocessor is programmed to initiate
timed defrost cycles.
2. The microprocessor is programmed to initiate
forced defrost cycles. The SPECTRUM
™
TS
uses temperature sensors to determine if
forced defrost is required.
3. Manual Defrost allows the operator to initiate
a defrost cycle by pressing the
D
EFROST
key.
See “Initiating a Manual Defrost Cycle” on
page 65.
DAS - Data Acquisition System
(Optional)
The DAS (Data Acquisition System) works with
the SPECTRUM
™
TS Microprocessor to monitor
and record the temperatures of (up to) six
additional sensors. The sensors are independent
from the microprocessor and are normally located
in the truck box to monitor load temperatures.
Data from the DAS sensors and the
SPECTRUM
™
TS Microprocessor can be
downloaded through a serial port to an IBM® PC
compatible computer. WinTrac
™
4.2 (or higher)
software is used to view and analyze the data.
Brief reports can be printed on a microprinter
connected to the serial port. WinTrac
™
4.4 (or
higher) is required for three temperature
operation.
WARNING: Turn the unit off by pressing
the
O
FF
key before opening doors or
inspecting any part of the unit. The unit
can start at any time without warning if it
has been turned on by pressing the
O
N
key.
