ICM OD
(Opening Degree)
- 0 100 - %
ICM valve Opening Degree is displayed during normal operation.
Running display value (see
j01, j05).
Main Switch j01 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
jo2 1 2 1 -
Operation mode
1: Modulating - ICM positioning according to Analogue input (see
j03)
2: ON/OFF - operating the ICM valve like an ON/OFF solenoid valve
controlled via Digital Input. See also j09.
Analog Input signal j03 1 4 2 -
Type of Analog input signal from external controller
1: 0-20mA
2: 4-20mA
3: 0-10V
4: 2-10V
Speed at ON/OFF
and Modulating Mode
j04 1 100 100 %
Speed can be decreased. Max. speed is 100 %
Not active when j01 = 2
If j02 = 2, the display will indicate speed in display. Low, Med, and
High also means ON/OFF operation.
If j04 < = 33, Low is displayed
33 < If j04 < = 66, Med is displayed
If j04 > = 67, High is displayed
Automatic calibration
j05 0 1 0 -
Not active before j26 has been operated.
Always auto reset to 0.
CA will ash in the display during calibration.
Analog Output signal
j06 0 2 2 -
Type of A0 signal for ICM valve position
0: No signal
1: 0 - 20mA
2: 4 - 20mA
Fail-safe
j07 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 j12
Digital Input function j09 1 2 1
Dene function when Dl is ON (short circuited Dl terminals) when j02 = 2
1: Open ICM valve (Dl = OFF = > Close ICM valve)
2: Close ICM valve (Dl = OFF = > Open ICM valve)

Old Alarms
j11 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 j12 0 100 50 -
Only active if j07 = 4
If fail-safe supply is connected and powercut occurs, ICM will go to
entered OD.
ICM conguration j26 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.
