s 3 944 ClimatixTM Climatix Extension Modules ECV2 POL98U.00/XXX POL98E.00/XXX The ECV2 extension modules are products of Climatix range. They are designed for driving a broad range of EEV valves with bipolar stepper motors. IOs of ECV2 extension modules can be configured for various applications of chiller and heat pump.
Electronic expansion valve Electronic expansion valves control refrigerant mass flow in evaporators in evaporators for chillers, air-conditioners and refrigerators applications. In addition modulating valves can be used for several control functions such as liquid injection, hot gas bypass and evaporator pressure regulation. ECV2 extension modules are designed as an electronic expansion valves driver, featuring two independently channel drive bipolar stepper motors.

The status of the BSP LED is defined as below: BSP LEDs Mode LED Per second flashing between red and green.
internal super capacitor has still power, the internal application starts again and can control the outputs (therefore BSP LED green). Note DIP switches Firmware of POL98X.00/XXX features different diagnostic functions such as disconnection detection, under voltage detection or shorted coil. The function "disconnection detection" is active only during valve / motor positioning, not during hold on. DIP switch is equipped with the extension module to communicate with the controller.
