Startup
When voltage is applied for the rst time
the display on the ICAD ( g. 2) will alternate
between showing: Actual opening degree and
A1.
A1 indicates an alarm which corresponds to:
No ICM valve selected. See Alarms for further
information.
Please observe that when the correct ICM valve
is entered in parameter ¡26 (see Parameter list)
an automatic calibration is carried out. I.e it is
not necessary to carry out another calibration in
parameter ¡05.
During calibration "CA" will be ashing in the
display.
The ICAD will brie y display "CS" every time ICM is
going to close and reach 0%.
General Operation
ICAD is equipped with an MMI (Man Machine
Interface) from which it is possible to see and
change di erent parameters to adapt the
ICAD and the corresponding ICM to the actual
refrigeration application. The operation of
parameters is done by means of the integrated
ICAD MMI ( g. 2) and consists of:
1
2
3
Down arrow push button ( g. 2, pos. 1)
decreases parameter number by 1 for each
activation
Enter push button ( g. 2, pos. 2)
Gives access to the Parameter list by
keeping the push button activated for 2
seconds. A Parameter list is shown below
(parameter ¡08):
© Danfoss | DCS (MWA) | 2015.12
Gives access to change a value once the
Parameter list has been accessed.
Acknowledge and save change of value of
a parameter.
To exit from the Parameter list and return
to the display of Opening Degree (OD) keep
the push button activated for 2 seconds.
Up arrow push button ( g. 2, pos. 3)
Increases parameter number by 1 for each
activation
Display ( g. 2, pos. 4)
Normally the Opening Degree (OD)
0 - 100 % of the ICM valve is displayed. No
activation of push buttons for 20 seconds
means that the display will always show
OD. Like below:
Displays the parameter
Displays the actual value of a parameter.
Displays the status by means of text
( g. 2, pos. 4)
Mod represents that ICAD is positioning
the ICM valve according to an analog input
signal (Current or Voltage).
Low represents that ICAD is operating the
ICM valve like an ON/OFF solenoid valve
with low speed according to a digital input
signal.
Med represents that ICAD is operating the
ICM valve like an ON/OFF solenoid valve
with medium speed according to a digital
input signal.

Alarms
ICAD can handle and display di erent alarms.
If an alarm has been detected the display at
ICAD ( g. 2) will alternate between showing
actual alarm and present Opening Degree.
If more than one alarm is active at the same
time only the alarm with the highest priority
will appear. A1 has the highest priority, A9 the
lowest.
Any active alarm will activate the Common
Digital Alarm output (Normally Open).
All alarms will automatically reset them-selves
when they physically disappear.
Old alarms (alarms that have been active, but
have physically disappeared again) can be found
in parameter ¡11.
Disposal Note
Equipment must be separate collected with
Electrical and Electronic waste. According to
Local and currently valid legislation.
De nition
Comments
of event
Alarm ON At start-up A1 will be displayed
Alarm ON Internal fault inside electronics.
Carry out:
1) Power OFF and Power ON
If A2 still active.
2) Make a Reset to factory setting
If A2 still active. Return ICAD to Danfoss
Alarm ON Not active if ¡01 = 2, or ¡02 = 2
When ¡03 = 1 and AI A > 22 mA
When ¡03 = 2 and AI A > 22 mA
or AI A < 2 mA
When ¡03 = 3 and AI A > 12 V
When ¡03 = 4 and AI A > 12 V
or AI A < 1 V
Alarm ON If 5 V < fail safe supply
<18 V. Enabled by ¡08
Alarm ON If supply voltage < 18 V
Alarm ON Check valve type selected.
Check presence of foreign body internally in ICM valve
Alarm ON Temperature for stepper motor component too high.
Ventilate/lower ambient ICAD temperature
Alarm ON Temperature for stepper motor component too high.
Ventilate/lower ambient ICAD temperature.
Alarm ON Only active if i16 = 1
If the valve is locked in more than 15 seconds.
ICM stopped and hold position
A9 ashing in display
A9 alarm can only be reset by Power OFF/ON of ICAD
