Danfoss actuator types ICAD600-900,ICAD1200A Electric valves actuator

Danfoss actuator types ICAD600-900,ICAD1200A Electric valves actuator introduction

There are two sizes of ICAD actuator that covers the range of valves from ICM 20 to ICM 150. The actuators have a fully weather protected enclosure with none of the moving parts exposed to the environment.The fast acting actuators and balanced valve design results in the valve being able to move from the fully closed to the fully open position in between 3 to 45 seconds depending on valve size and ICAD setup.Actuator types ICAD 600A and 1200A are dedicated for use with ICM motor operated valves. There are only two sizes of ICAD actuators that cover the range of valves from ICM 20 to ICM 150.

The ICAD is controlled via a modulating analogue signal (e.g. 4 – 20 mA / 2 – 10 V) or a digital ON / OFF signal. ICAD incorporates an advanced MMI

(Man Machine Interface), including continuous display of Opening Degree, which gives the user a very advanced and flexible setup procedure that can meet many different applications.

8 poled M12 male connector

ICAD can be delivered with (1.5 m. / 60 in.) or

without cables with M12 female connectors:

Power Supply cable with 4 poled M12 female

connector: 3 x 0.34 mm 2 (3 x ~22 AWG)

Control cable with 8 poled M12 female

connector: 7 x 0.25 mm 2 (7 x ~24 AWG)

Cable set with M12 female connectors in other

lengths are available. See the section "Spare

parts and accessories".

Danfoss actuator types ICAD600-900,ICAD1200A Electric valves actuator Function

Many different parameters can be configurated,

among these:

• Modulating, ON / OFF operation or Neutral

zone / 3 point control

• Analog input

0 – 20 mA or 4 – 20 mA

0 – 10 V or 2 – 10 V

• Digital Input

ICAD can be configured to support one or two

digital inputs.

When using one digital input, 0 – 10 V can not

be used at the same time.

By using two digital inputs at Neutral zone /

3 point control, the analog input (0/2 – 10 V,

0/4 – 20 mA) and Analog Output (0/4 – 20 mA)

can not be used at the same time.

• Analog output

0 – 20 mA or 4 – 20 mA

• Automatic or manual control

• Change of ICM valve speed

• Automatic calibration

• Multiple Fail Safe set-up options during power

cut

For service all Input and Output signals can be

recalled and observed from the ICAD display.

A password protection has been linked to the

parameter of entering the correct ICM valve

to avoid unintentional and non-authorised

operation.

ICAD can manage and display different alarms.

If an alarm has been detected the display will

alternate between showing: Actual alarm present

and Opening Degree of ICM valve. If more than

one alarm is active at the same time the alarm

with the highest priority will take preference. The

alarm with the highest priority is shown on the

display.

All alarms will automatically reset when

disappearing.

Previous alarms can be recalled for traceability

and service purposes.

Any active alarm will activate the common digital

alarm output.

All alarms will automatically reset when

disappearing.

ICAD provides two digital output signals to 3rd

party control equipment (e.g. PLC) indicating if

the ICM valve is completely open or completely

closed.

The hermetic magnetic motor coupling makes it

easy to dismount the ICAD from ICM valve.
