Description of the LED function
1. Chasing light (over all LEDs):
The bootloader is active.
No normal functions are possible.
2. All LEDs flash shortly every 6 s:
An internal data error was
detected and corrected automatically! The module still works
regularly. To acknowledge the error the module has to have
power cycled.
Yellow
Both yellow LEDs flash oppositely every 1 s:
The nonvolatile
stored parameters are inconsistent! To acknowledge the error
the data has to be saved with the SAVE command or the
corresponding Function button in the CHI-PC program. If one of
the FUNCTION parameter is changed to an incorrect value, that
parameter value is deleted purposely, and set to default
values. In this case the LEDs indicate no error.
Identical to the READY output.

No power supply or ENABLE is not activated
ON:
System is ready for operation
Flashing:
Error detected (e. g. valve solenoid or 4… 20 mA).
Not active when SENS = OFF.
