I hear that the EVD0000200 has been phased out and I need to replace this with the alternative. Is there a straight forward pin-to-ping compatible replacement?
The EVD0000200 is connected to the PCO controller of the Unit via pLAN network as the controller manages the comunication with the driver as a master. Removing the EVD 200 from the network you are likelly to generate on the PCO controller an "Offline Alarm" which will shut down the unit. The first thing to do is to disable the Driver from the configuration screens in the Chiller software. Depending on the make and model of the unit and the type of software that runs on the PCO (could be a custom made software or a standard Carel software) the configuration screens could be found in the "Manufacturing level" menu. Make sure you are provided from the Manufacturer of the unit with the password to access this menu level.
The same suction temperature sensor and suction pressure transducer previously connected to the EVD200 can also be connected to the EVD Evolution driver EVD0000E20. You would need to connect the auxiliary contact of the Compressor contactor (or a CT) to the remore enable digital input of the driver to enable the PID regulation when the compressor is activated.
