2.10 XCM25D Electronic controller
– Features
The XCM25D controller is designed to be a powerf ul, f lexible controller f or use in multiple
applications. It has been developed f or condensing units and allows the adjustment of all relevant
parameters by the user.
2.10.1 Description
WARNING
Electrical pins under voltage! Electrical shock hazard!
There are unused
f ast-on pins (C1 & DO2) on the XCM25D which could be under voltage. They
are covered by insulated f ast-on f lags in the f actory. Handle carefully when
removing insulating flags during service on site.
The controller is designed f or usage in an outdoor ref rigeration unit. It is rated to be used f or the
f ollowing environment:
▪
Outdoor controller ambient temperature for controller operation: -40 to +60
C
▪
Ambient temperature for storage: -40 to +80
C
▪
Maximum humidity: 90 % at 48
C (non-condensing)
▪
Board power: 24 V AC +15 % / -20 %
▪
Voltage sensing capabilities: three phase 200-240, 380-460, 575 V AC ± 10 %
The units of measure are selectable. The f actory default unit is bar (always considered relative) for
pressure and °C for temperature.

2.10.2 Functionality
The controller allows f or easy commissioning by the technician with the f actory settings at the highest
program level. It also offers the possibility to make substantial changes to the system optimization in
f urther programming levels. Advanced functionality can also be activated.
The f ollowing functions are covered by the controller:
▪
ref rigeration unit control, including tandem management;
▪
condenser fan control;
▪
voltage and current sensing (compressor protection);
▪
digital compressor control;
▪
Modbus/Canbus communication.
NOTE: The XCM25D controller includes all the functions necessary for the control of the
LOCU units. For additional functionalities please contact your local Application Engineering
representative.
