Universal Driver Module Series EXD-U02 EXD-U02 is a Universal Driver Module that enables the operation of Emerson stepper motor driven valves EX4-8, as well as the new series CV4-7 as: • High pressure gas valve for flash tank (applies only to CV valves for CO2) • Bypass valve from flash tank (applies only to CV valves for CO2) • Capacity control by means of hot gas bypass or evaporating pressure regulator • Crankcase pressure regulator • Heat reclaim regulator • Liquid level regulator Features • 4...20 mA or 0...10 V analog input signal • Step recovery function selectable • Plug and run, no parameter setting i.e. automatic operation • Easy configurable by Dip-switches • Digital input for valve closure at any time • Aluminum housing for DIN rail mounting EXD-U01/ EXD-U02 Emerson overcurrent built-in protection EXD-U02 drivers offer an exclusive, built-in internal hardware that ensures the valve stepper motor is never bearing an overcurrent, so the current is modulated accordingly to optimize the valve best working conditions in the safest way. Selection table * Controller Kit contains terminal kit Accessories Capacity data See “Electrical control valves EX4-8 / CV4-7” data. See technical bulletin “EXD-U02 Technical Bulletin” for detailed data and its application in CO2 systems. Optional uninterruptible power supply ECP-024 The optional uninterruptible power supply ECP-024 contains a rechargeable lead-acid battery, which provides enough energy to close the valve in case of power loss. One single ECP-024 can be connected to two EXD-U02 driver modules for closure of up to two valves.
