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).

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
Control type: Operating Control – Type
1 Action
Pollution Degree: 3

Supply voltage

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 600B/ICAD 600B-TS/1200B installed on all ICM, ICMTS & CVE valves.
All necessary electrical connections to be made.

Fig. 6

• Analog operation – 7 wired cable (A-G)
  Modulation control. Valve to be controlled from Danfoss electronics, type EKC/EKE (g. 7), or third party electronics (like e.g. PLC).

  • Connect analog input signals. Current (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 volt free contact.

  • Connect digital input signals (fig. 8). See
    Parameter list for configuration of digital input signals

  • Green (+) and Orange (GND) are connected to a volt free 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 – 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 configured.
  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 attended with PTFE ring and O-ring, remove both and replace it with O-ring included in ICAD (as instructed in g. 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.

| Steady red| Critical alarm – stopped operating|
---|---|---|---
| Flashing red| Severe alarm – danger of stopping operating
| Flashing blue| ICAD is connected via Bluetooth
| Flashing yellow| Warning
| Flashing green| OK

The main screen layout and navigation is as described below. ICAD will start up in alarm mode as the ICM configuration needs to be defened to start operation. Follow the steps on next page to set this up correctly.

STATUS BAR

Set valve (A1 alarm)

VALVE CONFIGURATION HELP

Change analog input signal (optional)

ICAD will function based on factory settings as soon as the valve configuration has been set. The default settings are Modulation using an analog input of 4–20 mA.

Bluetooth connection

In addition to the onboard display, all configuration and readings from ICAD B actuator can be performed via Bluetooth (using Coolcong mobile app) or via data communication.
CoolConfig can be downloaded and installed from iTunes Store or Google Play Store.
To connect with ICAD actuator, click Start scanning in CoolConfig and the list of available devices will be provided. To connect with a device, a password will be required.
The connection PIN is 0000 and serves to ensure that the connection is intentionally. Access is then read-only.
