Closing speed = 10
¡14 0 100 50/100
- No
See ¡04. Not applicable to CVE
If ¡26= 1 - 3 then factory setting = 100
If ¡26= 4 - 10 then factory setting = 50
Manual set point ¡15 0 100 0 - No When ¡01= 2, ¡15 determine the start up value
Encoder operation ¡16 0 1 1
- Yes
NB: Password protected. Password = 7
0: Encoder disabled. Means ICAD operation as ICAD 600A/ICAD 600A-TS/1200A
without encoder.
1: Encoder enabled
Forced closing when
ICM valve Opening
Degree < 3%
¡17 0 1 0
- No
Enable/Disable forced closing. Not applicable to CVE
0: When ICM valve Opening Degree < 3% it will be forced to close regardless of
requested ICM valve Opening Degree
1: When ICM valve Opening Degree < 3% no forced to closing will take place
Action when ICAD is
losing step
See Note 1
¡18 0 6 6
- No
Action when ICAD is losing step.
0: A boost starts if lost step is detected. After 15 sec, the A9 alarm is flashing and
DO A Common Alarm is ON.
A second boost starts after the time in ¡19 has elapsed. If the second boost cyklus
does not bring the valve back in operation a forced calibration is carried out.
3: A9 alarm flashing after 15 sec. DO A Common Alarm ON. ICAD is locked in
actual position.
No boost cyklus, Reset by Power OFF/ON, regardless of setting ¡21
6: Boost cyklus starts if lost step is detected.
After 3 boost cyklus the A9 alarm is flashing and DO A Common Alarm is ON.
Time interval between boost is set in ¡19.
The boost cyklus continues until the valve is back in operation.
Delay after boost,
before A9 alarm
See Note 1
¡19 0 30 1
Minutes No Time delay between two boosts. Linked to ¡18 function
Max offset value
See Note 1
¡20 3 15 3
% Yes
Password=13.
Offset value (numeric)=Requested Opening Degree [%] from Analog Input -
Opening Degree [%] from encoder (Used with ¡21)
Define how to Reset/
Suppress A9 alarm
See Note 1
¡21 0 4 1
- No
Define how to Reset/Suppress A9 alarm. A9 alarm means A9 flashing in display
and DO Common Alarm ON
0: Reset by Power OFF/ON
1: Autoreset when ICAD have succeeded to come back into normal operation.
Normal operation defined as: Offset value < ¡20 (Max offset value) and ¡22
(delay) has elapsed.
2: A9 alarm is suppressed, meaning no A9 flashing in display and DO Common
Alarm remains OFF
Reset delay for A9
See Note 1
¡22 1 20 5
Minutes No
Reset delay for A9. Use when ¡21= 1
OBSERVE: ¡22 is recommended always to be bigger than ¡19 (¡22>¡19)
Valve configuration ¡26 0 9 0
- Yes
NB: Password protected. Password = 11
0: No valve selected. Alarm A1 will become active
1: ICM 20 with ICAD 600A / ICMTS 20 with ICAD 600A-TS
2: ICM 25 with ICAD 600A
3: ICM 32 with ICAD 600A
4: ICM 40 with ICAD 1200A
5: ICM 50 with ICAD 1200A
6: ICM 65 with ICAD 1200A
7: ICM 100 with ICAD 1200A
8: ICM 125 with ICAD 1200A

Note 1:
After a parameter change, it is necessary to carry out a Power OFF/ON
