Danfoss ICAD 600A Actuator Platinum International

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.

NOTE!

If media temperature is lower than -30 °C (-22 °F) it is mandatory to set parameter ¡30 and ¡31.
See separate document attached in ICAD box: document number AN285243155312

Use

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

ICAD 600A	ICAD 600A-TS	ICAD 1200A
ICM 20	ICMTS 20	ICM 40

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:

Prefabricated ICAD cable length Code number| 1.5 m 027H0426| 3 m 027H0438| 10 m 027H0427| 15 m 027H0435

Electrical installation

General procedure for ICAD 600A/ICAD 600A-TS/1200A installed on all ICM, ICMTS & CVE valves.

All necessary electrical connections to be made.

ICM valve: Analog or digital operation
CVE/ICMTS valve: Analog only

Fig. 6

Analog operation – 7 wired cable (A-G) Modulation control. Valve to be controlled from 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.
Yellow (+) and Orange (GND) are used for current (mA) input.

or

Green (+) and Orange (GND) are used for Voltage (V) input.
Blue (+) and Orange (GND) are used for current (mA) output (optional, not mandatory).

Fig. 6

Digital operation – 7 wired cable (A-G)
ON/OFF ICM solenoid valve operation. ICM valve to be controlled by means of a digital voltfree contact.
Connect digital input signals (fig. 8). See Parameter list for configuration of digital input signals.
Green (+) and Orange (GND) are connected to a voltfree contact.
Digital output signals are optional, not mandatory.
Black (–) and Orange (GND) are connected to auxiliary relay for Common Alarm.
Brown (–) and Orange (GND) are connected to an auxiliary relay indicating ICM fully open.
Red (–) and Orange (GND) are connected to an auxiliary relay indicating ICM fully closed.

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 congurated. 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)

Neutral zone / 3 point control (fig. 9 – ICM only)

¡02 = 3

When ¡02 = 3 the factory setting of ¡04 (opening) and ¡14 (closing) are both set to 10.
When ¡02 = 3 the speed given by ¡04 (opening) and ¡14 (closing) are active

¡13 (Inverse operation) is active
¡16 = 1 (Encoder operation enable) is active.

¡13 = 0 (Direct operation)

DI1 = DI2 = OFF
ICAD/ICM maintain current position
DI1 = DI2 = ON
ICAD/ICM maintain current position
DI1 = ON, DI2 = OFF
ICAD increase opening degree
DI1 = OFF, DI2 = ON
ICAD decrease opening degree

¡13 = 1 (Inverse operation)

DI1 = DI2 = OFF
ICAD maintain current position
DI1 = DI2=ON
ICAD maintain current position
DI1 = ON, DI2 = OFF
ICAD decrease opening degree
DI1 = OFF, DI2 = ON
ICAD increase opening degree

Startup

When voltage is applied for the first time the display on the ICAD (fig. 2) will alternate between showing: Actual opening degree and A1.
A1 indicates an alarm which corresponds to: No valve selected. See Alarms for further information.
Please observe that when the correct valve is entered in parameter ¡26 (see Parameter list) an automatic calibration is carried out. I.e it is not necessary to carry out another calibration in parameter ¡05.
During calibration “CA” will be flashing in the display.
The ICAD will brie display “CS” every time the valve is going to close and reach 0%.

General Operation

ICAD is equipped with an MMI (Man Machine Interface) from which it is possible to see and change different parameters to adapt the ICAD and the corresponding valve to the actual refrigeration application. The operation of parameters is done by means of the integrated ICAD MMI (fig. 2) and consists of:

Down arrow push button (fig. 2, pos. 1) decreases parameter number by 1 for each activation
Enter push button (fig. 2, pos. 2)
- Gives access to the Parameter list by keeping the push button activated for 2 seconds. A Parameter list is shown below (parameter ¡08):
- Gives access to change a value once the Parameter list has been accessed.
- Acknowledge and save change of value of a parameter.
- To exit from the Parameter list and return to the display of Opening Degree (OD) keep the push button activated for 2 seconds.
Up arrow push button (fig. 2, pos. 3)
- Increases parameter number by 1 for each activation
Display (fig. 2, pos. 4)
- Normally the Opening Degree (OD) 0 – 100 % of the valve is displayed. No activation of push buttons for 20 seconds means that the display will always show OD. Like below:
- Displays the parameter
- Displays the actual value of a parameter.
Displays the status by means of text (fig. 2, pos. 4).
- Mod represents that ICAD is positioning the ICM, ICMTS or CVE valve according to an analog input signal (Current or Voltage).
- Low represents that ICAD is operating the ICM valve like an ON/OFF solenoid valve with low speed according to a digital input signal.
- Med represents that ICAD is operating the ICM valve like an ON/OFF solenoid valve with medium speed according to a digital input signal.
- High represents that ICAD is operating the ICM valve like an ON/OFF solenoid valve with high speed according to a digital input signal. Like below:

Alarms

ICAD can handle and display different alarms.
If an alarm has been detected the display at ICAD (fig. 2) will alternate between showing actual alarm and present Opening Degree.
If more than one alarm is active at the same time only the alarm with the highest priority will appear. A1 has the highest priority, A9 the lowest.
Any active alarm will activate the Common Digital Alarm output (Normally Open).
All alarms will automatically reset them-selves when they physically disappear.
Old alarms (alarms that have been active, but have physically disappeared again) can be found in parameter ¡11.
