Installation
Do not install ICAD before welding. This apply
for electrical as well as for mechanical installa-
tion. 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
and
.

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

Electrical data
Supply voltage is galvanically isolated from in-/
output.
Supply voltage
24 V DC (Tolerances; see below table)
Load
ICAD 600A, ICAD 600A-TS: 1.2 A
ICAD 1200A: 2.0 A
24 Volt DC ONLY
Please observe cable voltage drop.
Distance between the applied DC
transformer and the ICAD terminal
box may cause a voltage drop. Cross
section of cables and size of DC
transformer must be calculated so that
the voltage at all time at the ICAD terminal
box*, both during standstill and during
operation of ICAD, is within this range:

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

Supply voltage - 3 wired cable (I, II, III)
ICAD must be connected to a normal
24 V DC 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 valve or not.
See Mechanical installation.
Connect the White (+) and Brown (–) to a
24 V DC 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 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)
