Connecting the proportional valve

When connecting the proportional valve, be sure that the solenoid cables are routed
separately from the inductive position transducers.
It is strongly recommended that the solenoid cable is shielded.
For lengths up to 50 m cable 2 x 1.5 mm² of type LiYCY-CY (16 AWG double-shielded
cable) is recommended. When double shielded cable is used the outer shield can be
terminated entering the control cabinet and the inner shield needs to be terminated at
the controller card.

A CECc 75301-803-A002FA-H3008-G cable connector according to DIN EN 175 301-
803 and ISO 4400 is recommended for connecting the solenoids.

Single-solenoid valves are to be connected to solenoid A+/A-. The
solenoid B+/B- connection then remains open. For single-solenoid
valves, only positive command values are recognized as being valid.
When using single-solenoid valves in conjunction with current input
b22/b24, it must be noted that range +/-100% is set as default setting.
To be able to utilize the full range 0...20mA, range 0~100% must be
set.
