ENGLISH

Installation

Do not instal ICAD must 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 600, ICAD 900 and ICAD 1200 can be
used together with the following Danfoss
valves (fig. 1, 5a and 5b).

Electrical connection
Connection to ICAD is done via M12
connectors. ICAD has two M12 male
connectors build-in:
Power supply: 4 poled M12 male connector
Control signals: 8 poled M12 male connector
If ICAD is delivered with cables (1.5 m. (60
in.)) M12 female connectors: (Cable set with
M12 female connectors in other lengths are
available)

*) If Neutral zone / 3 point control is
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 600/900/1200
installed on all ICM valves.
All necessary electrical connections to be
made. Analog or digital operation of ICM
valve.

Modulation control. ICM valve to be
controlled from Danfoss electronics,
type EKC (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).

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 600/900/1200
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)
