• The max. cable distance between the controller and the valve depends on many factors like
shielded/unshielded cable, the wire size used in the cable, the output power for the
controller and the EMC.
• Keep controller and sensor wiring well separated from mains wiring.
• Connecting sensor wires more than specified length may decrease the accuracy of
measured values.
• Separate the sensor and digital input cables as much as possible(at least 10cm) from the
power cables to the loads to avoid possible electromagnetic disturbances. Never lay power
cables and probe cables in the same conduit (including those in electrical panels)

• All valves are driven in a bipolar mode with a 24 V supply chopped to control the current
(Current driver).
• The stepper motor is connected to the “Stepper Valve” terminals (see terminal assign
ment) with a standard M12 connection cable.
• To configure stepper motor valves other than Danfoss stepper motor valves, the correct
valve parameters must be set as described in the Valve configuration section by
selecting user defined valve.
