* Only used in application 1

LED indication:
Two sets of Light Emitting Diodes make it possible to follow the operation status of the valve and the controller.

LED A: Two status LEDs indicate power and controller operation

Power-up:

Normal operation:

LED B: Two status LEDs to indicate valve operation

Commonly used parameter identification in application 2

Note: In application 1, the most commonly used parameters are conÿgured in the AK-PC. Default commissioning password: “300”

Parameter	Default	Description
Main switch	0	0 = Off, 1 = ON
Mode	0	0=Application 1 – selection by AI4 1=Application 1 – High Pressure expansion module 2=Application 1 – Receiver Expansion module 3=Application 2 – Valve Driver Note: changing this setting also changes the EKE 1P address, causing communication with the graphical display to stop. Communication will resume after a power cycle.
