EMERSON XCM25D Controller Replacement
Controller replacement
- This manual describes the required working steps to replace a XCM-25D in case of controller damage on a ZX/CF unit.
- The spare part kit contains 3 “Hot Keys”, one for each unit family (ZXM*/CFM*, ZXL*/CFL* & ZXD*/CFD*).
Choose correct “Hot Key” depending on unit family, upload the parameters from the “Hot Key” to the controller, and adjust the values for electrical protection according to following instructions. - Interrupt the power supply of the unit. Disconnect the protection connectors and connect them on the new controller at the same terminals as before. Disconnect all the wires at the upper and lower parts of the controller.
- Open the cover of the cable guidance. Cut the cable ties, disconnect the grey and brown cables from the compressor contactor.
Pull out the cables from the current sensors of the controller. - Unlock the 4 controller locks. Remove the old controller and mount the new controller in its place.
Parameter uploading
Choose correct “Hot Key” depending on unit family, then upload the parameters from the “Hot Key” to the controller
- Turn the controller off.
- Insert a pre-programmed “Hot Key” into the 5-pin receptacle and turn the controller on.
- The parameter list of the “Hot Key” will be automatically downloaded into the controller memory. The “doL” message will blink followed a by a flashing “End” label.
- After 10 seconds, the controller will restart working with the new parameters.
Remove the “Hot Key”. - NOTE: The message “Err” is displayed in case of a failed programming operation. In this case turn the unit off, then on again if you want to restart the download, or remove the “Hot Key” to abort the operation.
Parameter setting
- In order to adjust a dedicated unit with the proper settings, parameters have to be modified.
- For units with the TFD motor version, modify parameters H07 and H09.
For the required values refer to Tables 1, 2 and 3.
