ICM OD (Opening
Degree)
- 0 100 - %
ICM valve Opening Degree is displayed during normal operation.
Running display value (see ¡01, ¡05).
Main Switch ¡01 1 2 1 -
Internal main switch
1: Normal operation
2: Manual operation. Valve Opening Degree will be ashing. With the down arrow
and the up arrow push buttons the OD can be entered manually.
Mode ¡02 1 2 1 -
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.
Analog Input signal ¡03 1 4 2 -
Type of Analog Input signal from external controller
1: 0 - 20 mA
2: 4 - 20 mA
3: 0 - 10 V
4: 2 - 10 V
Speed at ON/OFF and
Modulating Mode
¡04 1 100 100 %
Speed can be decreased. Max. speed is 100 %
Not active when ¡01 = 2
If ¡02 = 2 the display will indicate speed in display. Low, Med and High also
means ON/OFF operation.
If ¡04 < = 33, Low is displayed
33 < If ¡04 < = 66, Med is displayed
If ¡04 > = 67 High is displayed
Automatic calibration ¡05 0 1 0 -
Not active before ¡26 has been operated.
Always auto reset to 0.
CA” will ash in the display during calibration, if Enter push button has been
activated for two seconds.
Analog Output signal ¡06 0 2 2 -
Type of A0 signal for ICM valve position
0: No signal
1: 0 - 20 mA
2: 4 - 20 mA
Fail safe ¡07 1 4 1 -
Dene condition at power cut when fail safe is installed.
1: Close valve
2: Open valve
3: Maintain valve position
4: Go to OD given by ¡12
Digital Input function ¡09 1 2 1
Dene 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)
Password ¡10 0 199 0 -
Enter number to access password protected parameters: ¡26
Password = 11
Old Alarms ¡11 A1 A99 - -
Old alarms will be listed with the latest shown rst. Alarm list can be reset by
means of activating down arrow and up arrow at the same time for 2 seconds.
OD at powercut ¡12 0 100 50 -
Only active if ¡07 = 4
If fail safe supply is connected and powercut occurs ICM will go to entered OD.
ICM conguration ¡26 0 6 0
NB: Password protected. Password = 11
At rst start up A1 will ash in display. Enter valve type
0: No valve selected. Alarm A1 will become active.
1: ICM20 with ICAD 600
2: ICM25 with ICAD 600
3: ICM32 with ICAD 600
4: ICM40 with ICAD 900
5: ICM50 with ICAD 900
6: ICM65 with ICAD 900
Programming the ICAD When the ICAD motor is rst powered, the ICAD display will ash an A1 alarm. This means
that the ICM valve size that is being used with the ICAD motor needs to be 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 is selected. When the ICM
valve size is selected, the ICAD will calibrate itself to the ICM valve and will then be ready for
control by a 4-20mA signal. For most applications, this is the only programming that will
need to be done if the ICAD is going to be controlled by a 4-20mA input.
