LED Definitions
LEDs
Description of the LED function
Identical to the READY output.
OFF:
No power supply or ENABLE is not activated
ON:
System is ready for peration
Flashing:
Error discovered
Only active when SENS = ON
YELLOW A
Intensity of the solenoid current
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 be cycle
powered.
YELLOW A +
YELLOW B
Both yellow LEDs flash oppositely every 1 s:
The nonvolatile stored
parameters are inconsistent! To acknowledge the error, data has to
be saved with the SAVE command or the corresponding button in the
CHI-PC.
GREEN
GREEN + YELLOW A
