Unit Description
The TS-200 and TS-300 are microprocessor
controlled transport temperature control systems,
which utilize the ThermoGuard
®
µ
P-T
microcontroller to manage system functions.
The unit is a one-piece, front-mounted, medium
capacity diesel powered cooling and heating
system designed especially for straight trucks.
The unit mounts on the front of a truck with the
evaporator portion protruding into the box. It is
designed for use with totally chlorine free R-404A
refrigerant. The basic model provides the
following:
•
Model 30: Cooling and hot gas heating on
engine operation.
•
Model 50: Cooling and hot gas heating on
engine operation and electric standby
operation. Electric evaporator heaters are
optional.
Power is provided by the TK 3.74 three-cylinder,
special clean and silent diesel engine rated at
12.6 continuous horsepower (9.3 kw) at
2400 RPM. A belt drive system transfers energy
to the compressor, unit fans and alternator.
Electric standby power (Model 50) is provided by
an electric motor. A clutch on the diesel engine
isolates the engine during electric standby
operation.
Belt driven, dual evaporator fans provide superior
air throw. Exclusive space condenser provides
maximum cab clearance and reduced truck body
height on conventional chassis. Cube saver
evaporator optimizes space below the evaporator
for all types of cargo. Lightweight aluminum
frame allows increased payload.
The continuous monitoring function of the
µ
P-T
microprocessor optimizes the Thermo King unit’s
performance, thereby reducing fuel consumption
and unit down time. The unit’s self check can be
run before the daily distribution route to identify
any possible malfunctions. TherMax
TM
defrost/heating system increases unit heating
capacity for faster defrost.
The built-in CYCLE-SENTRY
TM
, an exclusive
Thermo King feature, automatically starts and
stops the unit according to temperature demands.
A range of programmable modes, like high speed
pull-down, allow tailoring the unit’s performance
to the load being distributed.
ThermoGuard
µ
P-T Controller
The
µ
P-T is a solid-state, programmable
microprocessor that contains integrated circuits
and software to control unit operation.
The
µ
P-T controller uses a remote control panel
and interface relay board. The remote control
panel inputs data into the controller and displays
operating conditions. The interface relay board
contains fuses to protect control circuits and
external relays to control unit operation. When the
controller is set below 15 F (-9.4 C), the
microprocessor locks out high speed heat.
Data Acquisition System
(Optional)
The Data Acquisition System (DAS) works with
the
µ
P-T 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
µ
P-T can be downloaded through a serial port to
an IBM
®
PC compatible computer. Win Trac
TM
software is used to view and analyze the data.
Brief reports can be printed on a microprinter
connected to the serial port.
Clutch
The clutch engages fully at 600 ± 100 RPM on
engine operation, constantly turning the
compressor and fans at both high and low speed.
