This forum has been designed as a Technical Support Hub for frequently asked questions we receive on the Air Handling products we supply.
Along with tutorials on navigating through our iSmart Air Handling Unit Software, this forum is home to troubleshooting guides for products such as CAREL, Belimo, Titan, Axio, Sontay and many more. Please get in touch if you have a query that you haven't found an answer to below.
The EVD0000200 is connected to the PCO controller of the Unit via pLAN network as the controller manages the communication with the driver as a master. Removing the EVD 200 from the network you are likely 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 remote enable digital input of the driver to enable the PID regulation when the compressor is activated.
