Programming XR-40CX or XR-60CX
Dixell Electronic Controller
Reprinted with permission from Dixell.
The Dixell XR-40CX (High Temperature) and XR-60CX (Medium
and Low Temperature) are fully configurable electronic
refrigeration controllers. These controls are used on PRO 3 Side
Mount units. All parameter values are reprogrammable and are
stored in the non-volatile memory.
The controller uses two levels of programming that can be
accessed through the keypad. The first level is the user level. It
gives access to six settings — temperature differential, defrost
cycle intervals, defrost termination temperature, draining time,
defrost fan delay and fan stop temperature.
The second level is the service level. It allows access to all other
parameters. It is recommended that changes in this level be
made only by a qualified technician.
