    53. IEV ELECTRONIC EXPANSION VALVE CONNECTION The Ichill 200D EVO can be connected to the IEV electronic expansion valve driver. The driver IEV regulates superheating autonomously; the connection to the controller Ichill is needed to synchronize the operation of the chiller or heat pump with the valve operation. The configuration parameters, the setting of superheat control must be performed in the driver IEV.

    external relay Accuracy: Out1..Out3: ±2% full scale Note: The electrical devices controlled by these analogue outputs must be powered separately with another transformer (do not use the same secondary of the controller's power) in order to prevent the outputs from malfunctioning or being damaged.
  • Page 192 GENERAL RULES Comply with the following recommendations during the installation process in order to prevent the device from malfunctioning.  Separate the signal cables from the power cables (it is recommended to use BELDEN 8772-type shielded cables) in order to prevent malfunction due to electromagnetic interference; do not use the same electrical conduit to install high voltage cabling and low voltage cabling.
