General information:
EXD-U01 Universal Driver Module is for driving Emerson stepper motor driven
electrical control valves series EX4...EX8 / CX4...CX7.
!
Safety instructions:
• Read operating instructions thoroughly. Failure to comply can result in
device failure, system damage or personal injury
• According to EN 13313 it is intended for use by persons having the
appropriate knowledge and skill.
• Before wiring disconnect all voltages from system and device.
• Do not operate system before all cable connections are completed.
• Do not apply 110/220/230V to any terminal of driver module
• Entire electrical connections have to comply with local regulations.
Installation and wiring
• Install electrical control valve in system according to operating instructions of
valve.
• Install Driver Module and other external electronic devices as shown in wiring
diagram (see Fig. 2).
• Keep separate the wires for power supply, stepper motor of valve and signal.
• Recommended wire size Ø 0.5 ... 2.5 mm
Setting (Fig.1):
• Disconnect voltage
• Set dip switches as per table below

4-20 mA
0-10V
Startup procedure:
• The valve must be closed before system charging in case of expansion valve or
hot gas bypass function. The valves are delivered at half open position.
Valve closure:
• Remove 24 V from digital input.
• Apply supply voltage to driver for the minimum time in below table: (valve
motor makes a characteristic sound until it reaches the closed position)

EX7/CX7/EX8
• After closure of valve evacuate the entire system.
• Then charge the system with refrigerant.
• Turn on digital input (24V)
• Start the system and check operating conditions.

Valve Synchronization:
• After power up EXD-U01 synchronizes the stepper motor driven valve with the
reference point in the fully closed position.
Technical data, power supply:
• Main supply voltage: 24 VAC ±10%, 50-60 Hz (use 1.0 A external fuse).
Note: 24 VDC supply voltage can be used but it results to lower MOPD and it
needs to be verified by system manufacture.
• Use a safety class II transformer.
Minimum power required 20 VA.
• Emergency supply voltage Ub (from ECP-024): +18 VDC.
Inputs:
• 1 analog input 4...20 mA, burden 364 Ω, or
1 analog input 0...10 V, impedance 27 kΩ.
1 digital input: 24 VAC/DC (+10%, -15%), 50-60 Hz.
Outputs:
4 current outputs for stepper motor of EX4...EX8/ CX4...CX7.
Uninterruptible power supply ECP-024
• Power supply voltage: 24 VAC ± 10%
• Power outputs: two, each +18 VDC
