SMART REEFER 2 (SR-2) Control
System
The SR-2 controller is a microprocessor control system
designed for transport refrigeration. The SR-2 integrates the
following functions: changing setpoint and operating mode,
viewing gauge, sensor and hourmeter readings, initiating
defrost cycles, and viewing and clearing alarms.
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
HMI control panel is mounted on the face of the control box. It
is clearly visible through an opening in the lower roadside
service door.
See “Operating Instructions” for more information about the
SR-2 controller.
Depending on the air temperature in the trailer, as sensed by
the microprocessor controller, the unit will typically operate in
one of the following modes:
CYCLE-SENTRY Operation
•
High Speed Cool
•
Low Speed Cool
•
Null (Engine Off)
•
Low Speed Heat
•
High Speed Heat
•
Defrost
Continuous Run Operation
•
High Speed Cool
•
Low Speed Cool
•
Low Speed Modulated Cool (Optional SB-210+)
•
Low Speed Modulated Heat (Optional SB-210+)
•
Low Speed Heat
•
High Speed Heat
•
Defrost
