ENGLISH

Installation

Do not instal ICAD before welding.
This apply for electrical as well as for
mechanical installation.
Please observe that ICAD when
connected to 24 V d.c., will send
out acoustic noise at stand still. This
has no influence on the function/
operation of the ICAD.

Use

ICAD 600A, ICAD 600A-TS and ICAD 1200A
can be used together with the following
Danfoss valves (fig. 1, 5a and 5b).
ICAD 600A ICAD 600A-TS
ICM 20 ICMTS 20
ICM 25
ICM 32

Electrical connection
Connection to ICAD is done via M12
connectors. ICAD has two M12 male
connectors build-in:

in.)) M12 female connectors: (Cable set with
M12 female connectors in other lengths are
available)

selected (parameter i02 = 3) then
E and G is used as DI2 - Digital
ON/OFF input. Se fig. 9.

Electrical installation

General procedure for ICAD 600A/ICAD
600A-TS/1200A installed on all ICM valves.
All necessary electrical connections to be
made. Analog or digital operation of ICM
valve.

Analog operation - 7 wired cable (A-G)
Modulation control. ICM valve to be
controlled from Danfoss electronics, type
EKC/EKE (fig. 7), or third party electronics
(like e.g. PLC).
Connect analog input signals. Currrent
(mA) or Voltage (V). See Parameter list
for configuration of analog input signals.
Yellow (+) and Orange (GND) are used for
current (mA) input.
or
Green (+) and Orange (GND) are used for
Voltage (V) input.
Blue (+) and Orange (GND) are used
for current (mA) output (optional, not
mandatory).

Green (+) and Orange (GND) are
connected to a voltfree contact.
Digital output signals are optional, not
mandatory.
Black (–) and Orange (GND) are
connected to auxiliary relay for Common
Alarm.

Supply voltage - 3 wired cable (I, II, III)
ICAD must be connected to a normal
24 V d.c. supply. As an option, a fail safe
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 ICM valve or not.
See Mechanical installation.
Connect the White (+) and Brown (–) to a
24 V d.c. supply voltage (fig. 6).
Fail safe supply as an option (not
mandatory).
Connect the Black (+) and Brown (–) to a
fail safe supply.
Mechanical installation
General procedure for ICAD 600A/ICAD
600A-TS/1200A installed on all ICM 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 ICM valve.
The magnet coupling will drag the ICM
and ICAD together and in position.
Push ICAD in place.
Fasten ICM 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)
