Controller
The controllers are regulating units for the adjustment of refrigeration functions and operating data. They enable
readouts of system messages and diagnostic data. The controllers have a service interface which enables various
configurations. There is also a connection for collective fault indications.
Cooling units with a standard controller (SC) have a display unit with a green LED light (1). The display unit is
located on the unit cover. Permanent illumination of the green LED light (1) while the mains voltage is connected
indicates fault-free operation. The LED light (1) begins if there is an operational fault or a malfunction. For detailed
information about the error messages, see
2.4.3
DIP switch
The DIP switch on the control circuit board enables regulation and control of setpoints and limit values for
temperatures; see
