Operating Instructions
SMART REEFER 2 (SR-2)
Control System
The microprocessor components are located
inside the control box, which is located inside the
lower roadside service door. The microprocessor
is connected to an HMI (Human Machine
Interface) Control Panel. It is used to operate the
unit. The Cargo Watch and Service Watch ports
are used to retrieve data from the data logging
system.
Microprocessor On/Off Switch
This switch supplies or removes electrical power
to the microprocessor. It is located on the left side
of the control box.
HMI Control Panel
Use the HMI control panel to operate the unit.
Refer to the SB-210/310 Operator’s Manual
TK 51585 and the SR-2 Microprocessor Control
System Diagnostic Manual TK 51587 for more
information.
The HMI control panel has a display and eight
touch sensitive keys. The display is capable of
showing both text and graphics. The four keys on
the left and right sides of the display are dedicated
keys. The four keys under the display are “soft”
keys. The function of “soft” keys change
depending on the operation being performed. If a
soft key is active, its function will be shown in the
display directly above the key.

CAUTION: The microprocessor is
vulnerable to damage from Electro Static
Discharge (ESD). This damage is not
always immediately apparent. As a result
of ESD, a circuit can be damaged but may
continue to operate temporarily, only to
fail later.
