Do not install ICAD before welding. This apply
for electrical as well as for mechanical installation. Please observe that ICAD when connected
to 24 V DC, will send out acoustic noise at stand
still. This has no influence on the function/
operation of the ICAD.
NOTE!
If media temperature is lower than
-30 °C (-22 °F) it is mandatory to set
parameter ¡30 and ¡31.

supply is possible by means of a battery or
UPS (Uninterruptible Power Supply). When
voltage is applied as described below, ICAD is
ready to be configurated. See Parameter list.
ICAD configuration can be done
independently whether the ICAD is installed
on the valve or not.
See Mechanical installation.
Connect the White (+) and Brown (–) to a

Mechanical installation
General procedure for ICAD 600A/ICAD
600A-TS/1200A installed on all valves (fig. 3).
Check that the three socket set screws are
fully unscrewed counter clockwise with a
2.5 mm Hexagon key.
Mount ICAD by slowly lowering it on top of
the valve.
The magnet coupling will drag the valve and
ICAD together and in position.
Push ICAD in place.
Fasten valve and ICAD with the three socket
set screws using a 2.5 mm Hexagon key.
Special moisture seal is damaged if
screws are removed (fig. 3, pos. A)

When ¡02 = 3 the factory setting of ¡04

When ¡02 = 3 the speed given by ¡04 (opening)

When voltage is applied for the first time
the display on the ICAD (fig. 2) will alternate
between showing: Actual opening degree and
A1.
A1 indicates an alarm which corresponds
to: No valve selected. See Alarms for further
information.
Please observe that when the correct 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 flashing in the
display.
The ICAD will briefly display “CS” every time the
valve 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 different parameters to adapt the ICAD
and the corresponding valve to the actual
refrigeration application. The operation of
parameters is done by means of the integrated
ICAD MMI (fig. 2) and consists of:
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 (fig. 2, pos. 3)
Increases parameter number by 1 for each
activation
Display (fig. 2, pos. 4)
Normally the Opening Degree (OD)
0 - 100 % of the 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
(fig. 2, pos. 4).
Mod represents that ICAD is positioning the
ICM, ICMTS or CVE 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.
High represents that ICAD is operating the
ICM valve like an ON/OFF solenoid valve
with high speed according to a digital input
signal. Like below:
Alarms
ICAD can handle and display different alarms.
If an alarm has been detected the display at
ICAD (fig. 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.

Elektrische Daten
Die Versorgungsspannung ist galvanisch vom
Ein-/Ausgang getrennt.
Versorgungsspannung
24 V DC (Toleranzen; siehe Tabelle unten)
Last ICAD 600A, ICAD 600A-TS: 1,2 A
ICAD 1200A: 2,0 A
NUR 24 V DCBitte den Spannungsabfall im Kabel
beachten.
Durch den Abstand zwischen
eingesetztem GleichstromTransformator und ICAD-Anschlusskasten
wird ein Spannungsabfall auftreten. Der
Kabelquerschnitt und die Größe des
Gleichstrom-Transformators müssen so
berechnet werden, dass die Spannung am ICAD-Anschlusskasten*, immer, d. h. bei einem
Stillstand und während des ICAD-Betriebs,
innerhalb dieses Bereichs liegt:
1,5 m

Elektrischer Anschluss
Der Anschluss an den ICAD erfolgt über M12Stecker. Der ICAD verfügt über zwei integrierte
M12-Stecker:
Versorgungsspannung: 4-poliger M12-Stecker
Steuersignale: 8-poliger M12-Stecker
Wenn der ICAD mit Kabeln bestellt wird beträgt
die Kabellänge automatisch 1,5m! Wird eine
andere Kabellänge benötigt wird der ICAD ohne
Kabel (mit Steckern) bestellt und das gewünschte
Kabel wird zusätzlich als Zubehör ausgewählt!wird
(1,5 m) M12-Steckbuchsen: (Kabelsatz mit M12Steckbuchsen ist in anderen Längen verfügbar)

Elektrische Installation
Allgemeine Vorgehensweise, wenn der ICAD 600A/
ICAD 600 A-TS/1200A auf allen ICM-, ICMTS- und
CVE-Ventilen installiert wird.
Alle erforderlichen elektrischen Anschlüsse
vornehmen.
ICM-Ventil: Analoger oder digitaler Betrieb
ICMTS-/CVE-Ventil: Nur analoger Betrieb

Modulierende Regelung. Das Ventil wird über
Danfoss-Regler vom Typ EKC/EKE (Abb. 7) oder
über Steuergeräte von Drittanbietern
(z. B. SPS) geregelt.
Analoge Eingangssignale anschließen.

Digitale Eingangssignale anschließen (Abb. 8)
Siehe Parameterliste für die Konfiguration
der digitalen Eingangssignale.
Grün (+) und Orange (Masse) sind an einen
potenzialfreien Kontakt angeschlossen.
Digitale Ausgangssignale sind optional, nicht
zwingend erforderlich.
Schwarz (-) und Orange (Masse) sind an ein
Hilfsrelais für einen Sammelalarm
angeschlossen.
Braun (-) und Orange (Masse) sind an ein
Hilfsrelais angeschlossen, das aktiviert wird
wenn das ICM voll geöffnet ist.
Rot (-) und Orange (Masse) sind an ein
Hilfsrelais angeschlossen, das aktiviert wird
wenn das ICM voll geschlossen ist.
Versorgungsspannung – 3 adriges Kabel
(I, II, III) Der ICAD ist an eine normale
Gleichspannungsversorgung von 24 V
anzuschließen. Optional ist eine eigensichere
Stromversorgung über eine Batterie oder
USV (unterbrechungsfreie Stromversorgung)
Wird der ICAD wie unten beschrieben unter
Spannung gesetzt, ist er für die Konfiguration
bereit. Siehe Parameterliste.
Die ICAD-Konfiguration erfolgt unabhängig
davon, ob der ICAD auf dem Ventil installiert
wurde oder nicht.
Siehe Mechanische Installation.
Weiß (+) und Braun (-) an eine
Versorgungsspannung von 24 V DC
anschließen (Abb. 6).
Eine eigensichere Stromversorgung ist optional
(nicht zwingend erforderlich).
Schwarz (+) und Braun (-) an eine eigensichere
Stromversorgung anschließen.
Mechanische Installation
Allgemeine Vorgehensweise, wenn der ICAD
600A/ICAD 600 A-TS/1200A auf allen Ventilen
installiert wird (Abb. 3).
Einen 2,5-mm-Imbuschlüssel gegen den
Uhrzeigersinn drehen und überprüfen, ob die
drei Sockelschrauben vollständig gelöst sind.
Den ICAD langsam oben auf das Ventil
setzen.
Die Magnetkupplung wird das ICM und den
ICAD miteinander verbinden und in Position
bringen.
Den ICAD so positionieren, dass er einfach
bedient werden kann..
Das ICM und den ICAD mittels der drei
Sockelschrauben und einem 2,5-mmImbuskantschlüssel fixieren
Durch etwaiges Lösen der
Deckelschrauben wird die spezielle
Feuchtigkeitabdichtung zerstört!!!
spezielle Feuchtigkeitsdichtung wird
beschädigt, wenn die Schrauben
entfernt werden (Abb. 3, Pos. A)
Neutralzone/3-Punkt-Regelung (Abb. 9 – nur
ICM)¡02 = 3
Wenn ¡02 = 3, wird sowohl die Öffnungs- wie
auch die Schliessgeschwindigkeit automatisch
auf 10 gesetzt!
Sollten sich diese Werte als zu hoch oder niedrig
erweisen können die Werte im Parameter
i04(Öffnen) und ¡14 (Schliessen) angepasst
werden! ist Geschwindigkeit definiert.
