Danfoss ICAD 600A / ICAD 1200A Quick Start Guide

Before you start using ICAD:

⚠️ 24 Volt d.c. ONLY

Initial Setup (Steps 1-3)

Step 1: Connect the ICAD unit

Attach the ICAD unit to the ICM valve. Ensure the connection is tightened clockwise (CW).

Step 2: Wire the ICAD unit

Connect the wiring to the terminal box. The terminal box is not supplied by Danfoss.

Terminal Connections:

* Uninterruptable Power Supply

⚠️ 24 Volt d.c. ONLY

Important Note on Voltage Drop: Please observe cable voltage drop. The distance between the applied d.c. transformer and the ICAD terminal box may cause a voltage drop. The cross-section of cables and the size of the d.c. transformer must be calculated so that the voltage at the ICAD terminal box is within the specified range (Min. 21 V d.c., Max. 26.4 V d.c.) at all times, both during standstill and operation. Do not measure inside the ICAD itself.

Prefabricated ICAD cable length:

Step 3: Power On

Connect the power supply.

Programming the ICAD (Step 4)

Valve size setup (mandatory)

When powering up the ICAD, 'A1' will flash in the display.

Procedure:

1. Hold down the [Enter] button for 2 seconds to enter programming mode.
2. Press [Increase value] until you reach parameter 10.
3. Press [Enter] to go to parameter 10.
4. Press [Increase value] until you reach parameter 11 (password).
5. Press [Enter] to confirm.
6. Press [Increase value] until you reach parameter 26.
7. Press [Enter] to confirm.

Selecting ICM size or CVE:

• Press [Decrease value] or [Increase value] to select the correct ICM size or CVE. The available options are:
• 1: ICM 20 with ICAD 600A
• 2: ICM 25 with ICAD 600A
• 3: ICM 32 with ICAD 600A
• 4: ICM 40 with ICAD 1200A
• 5: ICM 50 with ICAD 1200A
• 6: ICM 65 with ICAD 1200A
• 7: ICM 100 with ICAD 1200A
• 8: ICM 125 with ICAD 1200A
• 9: ICM 150 with ICAD 1200A
• 10: CVE pilot with ICAD 1200A

After selection, the display will show the selected valve label ID (e.g., 'ICM 20-A').

The ICAD unit will now calibrate the ICM/CVE.

Hold down the [Enter] button for 2 seconds to exit programming mode.

Changing analogue input signal (optional) (Step 5)

Procedure:

1. Hold down the [Enter] button for 2 seconds to enter programming mode.
2. Press [Increase value] until you reach parameter 03.
3. Press [Enter] to confirm.
4. Press [Decrease value] or [Increase value] to select the desired analogue input signal:
• 1: 0-20 mA
• 2: 4-20 mA* (default factory setting)
• 3: 0-10 V
• 4: 2-10 V
5. Press [Enter] to confirm.

Hold down the [Enter] button for 2 seconds to exit programming mode.

Note: If an 'A3' alarm occurs, the analogue input signal is out of range.

Factory reset of ICAD

1. Disconnect power.
2. Press and hold the [Decrease value] and [Enter] buttons simultaneously while reconnecting power.
3. Release the buttons when the display shows 'A1'.

Note: If a factory reset has been performed, the ICAD will start flashing 'A1' in the display.

⚠️ 24 Volt d.c. ONLY
