ICAD 600B Motor Actuator

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).

ICAD 600B	ICAD 600B-TS	ICAD 1200B
ICM 20	ICMTS 20	ICM 40
ICM 25	ICMTS 50	ICM 50
ICM 32	ICMTS 80	ICM 65
		ICM 100
		ICM 125
		ICM 150
		CVE pilot valve

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:

Prefabricated ICAD cable length Code number		1.5 m 027H0426	3 m 027H0438	10 m 027H0427	15 m 027H0435
Voltage ICAD terminal (600B/12006) [V DC]	Min.	21	22	23	24
Voltage ICAD terminal (600B/12006) [V DC]	Max.	26.4

* Do not measure inside the ICAD itself (value can be checked in ICAD B menu).
Fail safe supply
24 V DC (Tolerances; see table above)
Load ICAD 600B, ICAD 600B-TS: 1.2 A ICAD 1200B: 2.0 A

• 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

Push ICAD in place
Fasten valve and ICAD with the two socket set screws using a 3 mm Hexagon key

Special moisture seal is damaged if screws are removed (fig. 3).

Power on & start operation

ICAD has a light guide viewable from three sides, which indicates the status. Immediately after power on the light guide and display lights up.The main screen layout and navigation is as described below. ICAD will start up in alarm mode as the ICM configuration needs to be defined to start operation. Follow the steps on next page to set this up correctly.
