Electrical installationGeneral procedure for ICAD 600/900 installed on all ICM valves.All necessary electrical connections to be made. Analog or digital operation of ICM valve.Fig. 6Analog operation - 7 wired cable (A-G) Modulation control. ICM valve to be controlled from Danfoss electronics, type EKC (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.Grey (+) and Yellow (GND) are used for current (mA) input. orPink (+) and Yellow (GND) are used for Voltage (V) input.Blue (+) and Yellow (GND) are used for current (mA) output (optional, not mandatory). Fig. 6Digital 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.Pink (+) and Yellow (GND) are connected to a voltfree contact.Digital output signals are optional, not mandatory.White (–) and Yellow (GND) are connected to auxiliary relay for Common Alarm.Brown (–) and Yellow (GND) are connected to an auxiliary relay indicating ICM fully open.Green (–) and Yellow (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 d.c. 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 ICM valve or not. See Mechanical installation.Connect the Brown (+) and Green (–) to a 24 V d.c. supply voltage (fig. 6).
Fail safe supply as an option (not mandatory).
Connect the White (+) and Green (–) to a fail safe supply.Mechanical installationGeneral procedure for ICAD 600/900 installed on all ICM 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 ICM valve.The magnet coupling will drag the ICM and ICAD together and in position.Push ICAD in place.Fasten ICM 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)StartupWhen 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 ICM valve selected. See Alarms for further information.Please observe that when the correct ICM valve is entered in parameter ¡26 (see p. 5 for Parameter list) an automatic calibration is carried out. I.e it is not necessary to carry out another calibration in parameter ¡05.See Parameter list for selecting the correct It is important to select and verify correct valve.

The operation of parameters is done by means of the integrated ICAD MMI (fig. 2) and consists of:123Down arrow push button
(fig. 2, pos. 1) decreases parameter number by 1 for each activationEnter 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 activationDisplay (fig. 2, pos. 4)Normally the Opening Degree (OD) 0 - 100 % of the ICM valve is displayed. No activation of push buttons for 20 seconds means that the display will always show OD. Like below:Displays the parameterDisplays 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 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:AlarmsICAD can handle and display different alarms.DescriptionICMalarm textCommentsNo valve type selectedA1At start-up

A1 has the highest priority, A5 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.Disposal Note The Product contains electrical components And may not be disposed together with domestic waste. Equipment must be separate collected with Electrical and Electronic waste. According to Local and currently valid legislation.
