Programming the ICAD
actuator
When the ICAD actuator is first powered on, the ICAD display will flash an A1 alarm. This alarm is a
reminder that the ICM valve being moved by the ICAD has not been selected in parameter
¡
26. Parameter
¡
26 is password protected and will not appear in the parameter list until the user enters the password in
parameter
¡
10. The password is “11” and will allow the user to access parameter
¡
26 where the appropriate
valve size can be selected. Once the ICM valve size is selected (see page 3 on how to identify ICM size), the
ICAD actuator will calibrate itself to that particular size and will then be ready to receive a control signal.

Operation mode
1: Modulating – ICM positioning according to Analog Input (see ¡03)
2: ON/OFF - operating the ICM valve like an ON/OFF solenoid valve
controlled via Digital Input. See also ¡09.
3: Neutralzone / 3 point control. Increase/Decrease Opening Degree by
Digital Input. See fig. 9

When ¡02 = 1
0: Increasing Analog Input signal => Increasing ICM Opening Degree
1: Increasing Analog Input signal => Decreasing ICM Opening Degree
When ¡02 = 3
0: DI1 = ON, DI2 = OFF => Increasing ICM Opening Degree.
DI1 = OFF, DI2 = ON => Decreasing ICM Opening Degree
DI1 = DI2 = OFF
=> ICAD/ICM maintain current position
DI1 = DI2 = ON
=> ICAD/ICM maintain current position
1: DI1 = ON, DI2 = OFF => Decreasing ICM Opening Degree
DI1 = OFF, DI2 = ON => Increasing ICM Opening Degree
DI1 = DI2 = OFF
=> ICAD/ICM maintain current position
DI1 = DI2 = ON
=> ICAD/ICM maintain current position
