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.

applications on-site (change speed, ON / OFF,
Fail Safe operation, modulating valve, etc..)
• Open – Close time: 3 – 45 seconds depending
on valve size
• Modulating, ON / OFF operation or Neutral
zone / 3 point control

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
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.
