Wiring the ICAD

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.
