Installation

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.

Use

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

Electrical data

Supply voltage is galvanically isolated from in-/output.
ICAD is a Class III product.
PSUs connected to ICAD must be SELV<100 VA
For UL compliance: PSU must be Class 2 NEC

Supply voltage

24 V DC (Tolerances; see below table)
Load

ICAD 600B, ICAD 600B-TS: 1.2 A

ICAD 1200B: 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:

Data communication

RS 485: It is important that the installation of the data
communication cable is done correctly. For further
guidance, see literature No. RC8AC902.
Remember termination at the bus termination.

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

Supply voltage

- 4 wired cable(I, II, III, IIII)

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 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 600B/ICAD 600B-TS/1200B
installed on all valves (fig. 3).

Check that the two socket screws are fully
unscrewed counter clockwise with a
3 mm Hexagon key

If valve is fitted with PTFE ring and O-ring, remove
both and replace it with O-ring included in ICAD
(as instructed in fig. 3)

Mount ICAD by slowly lowering it on top of the
valve.

The magnet coupling will drag the valve and ICAD
together and in position
