ICM/ICAD Motorized Valve
Wiring the ICAD
Electrical Data
Danfoss (USCO / MKS), 11 - 006
Installation, Programming, and Troubleshooting
Note: The ICAD is powered by a 24 Volt DC power source.
There are two cables pre-mounted and connected to the ICAD motor actuator. Never try to
open the ICAD motor because the special moisture seal will be damaged.
The power cable consists of 3 wires:
•
Green: (–) common (ground)
•
Brown: (+) positive from 4VDC power source
•
White: (+) positive from UPS/battery backup (optional)
The control cable consists of 7 wires:
•
Yellow: (–) common (ground)
•
Gray:
(+) positive 4-0mA or 0-0mA input to control ICAD motor
•
Blue:
(+) positive 4-0mA or 0-0mA output from ICAD for valve
position feedback
•
Pink:
(+) positive -10V or 0-10V input to control ICAD motor. Also used as a
digital input with the yellow wire for on/off solenoid valve operation.
•
White: common alarm (digital NPN transistor output when combined with
yellow wire)
•
Brown: indicates ICM is fully open (digital NPN transistor output when combined
with yellow wire)
•
Green: indicates ICM is fully closed (digital NPN transistor output when combined
with yellow wire)
Supply voltage is galvanically isolated from input and output wires.
