Installation, Programming, and Troubleshooting
The ICAD actuator has a number of very useful service parameters which should always be consulted first.
In addition, a manual tool should always be available to manually close the valve completely in the event
the ICAD has failed. When using the manual tool, turn the tool clockwise to open the valve and counter-
clockwise to close the valve.
NOTE:
When rotating the valve manually you are changing the position of the valve to a value different than
what is in the actuator's memory. Therefore, a calibration must be performed when ICAD is remounted
to the valve. If power is cut from the actuator prior to using the manual tool or after the valve has been
adjusted, no problem will occur as the valve will automatically recalibrate itself once power is restored.
Power can easily be disconnected and reconnected by unscrewing and then reconnecting the power
cable from the ICAD actuator.

Comments
At start-up A1 will be displayed until parameter ¡26 is set
Internal fault inside electronics.
Carry out:
1) Power OFF and Power ON
If A2 still active.
2) Make a Reset to factory setting
If A2 still active. Return ICAD to Danfoss
Not active if ¡01 = 2, or ¡02 = 2
When ¡03 = 1 and AI A > 22 mA
When ¡03 = 2 and AI A > 22 mA
or AI A < 2 mA
When ¡03 = 3 and AI A > 12 V
When ¡03 = 4 and AI A > 12 V
or AI A < 1 V
If 5 V < fail safe supply
<18 V. Enabled by ¡08
If supply voltage < 18 V
Check valve type selected.
Check presence of foreign debris inside ICM valve
ICAD stepper motor temperature too high
Only active if i16 = 1
If the ICM valve is locked for more than 15 seconds (unable to reach its requested
position) A9 will flashin display.
A9 alarm can only be reset by Power OFF/ON of ICAD
