Installation, Programming, and Troubleshooting
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
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
¡
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.

Setting Pass Comments
stored word
- ICM valve Opening Degree in % is displayed during normal operation.
Running display value (see ¡01, ¡05).
Yes No Internal main switch
1: Normal operation
2: Manual operation. Valve Opening Degree will be flashing. With the down
arrow and the up arrow push buttons the OD can be entered manually.
Yes No 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 ICAD instructions for wiring diagram
Yes No Type of AI signal from external controller
1: 0-20 mA
2: 4-20 mA
3: 0-10 V
4: 2-10 V
Yes No Speed can be set in % of full speed. Max. speed is 100 % - Not active in manual
operation (¡01 = 2)
If ¡26= 1 - 3 then factory setting =100
If ¡26= 4 - 9 then factory setting =50
If ICM is opening and (¡04 < = 33) or ICM is closing and (¡14 < = 33)
=> Low is displayed.
If ICM is opening and (33 < If ¡04 < = 66) or ICM is closing and (33 < If ¡14 < = 66)
=> Med is displayed.
If ICM is opening and (¡04 > = 67) or ICM is closing and (¡14 > = 67)
=> High is displayed
No No Not active before ¡26 has been operated.
Always resets to 0 after calibration.
CA will flash in the display during calibration,
if Enter push button has been activated for two seconds
0: No Calibration
1: Normal forced calibration - CA flashing slowly
2: Extended calibration – CA flashing rapidly
Yes No Type of A0 signal for ICM valve position
0: No signal
1: 0-20 mA
2: 4-20 mA
Yes No Define condition at power cut and fail safe supply is installed.
1: Close valve
2: Open Valve
3: Maintain valve position
4: Go to OD given by ¡12"
Yes Yes Fail safe supply connected and enable of A4 alarm:
0: No
1: Yes
Yes No Define function when DI is ON (short circuited DI terminals) when ¡02 = 2
1: Open ICM valve (DI = OFF = > Close ICM valve)
2: Close ICM valve (DI = OFF = > Open ICM valve)
Enter number to access password protected parameters: ¡26
No -
Password = 11
No No Old alarms will be listed with the latest shown first. Alarm list can be reset
by means of activating down arrow and up arrow at the same time for 2
seconds.
Yes No Only active if ¡07 = 4
If fail safe supply is connected and power cut occurs, the ICM will go to the
specified OD.
