Error display through flashing codes
The "Safety Gate" and "Input" LEDs send flash signals; an error code can be established
from the number and sequence. The "Power/Fault" LED illuminates red.
Each error code is indicated by three short flashes of the "Input" or "Safety Gate" LED.
After a longer pause, the LED will then flash at one second intervals. The number of LED
flashes corresponds to a digit in the error code. The error code can consist of up to 3 digits.
The digits are separated by a longer period without flashing. The entire sequence is con-
stantly repeated.
Number of flashes 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Decimal error code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0
Example:
Error code 1,4,1:

Meaning of flash frequency:
Flash frequency Meaning
I 3 times, short Code for error message
II Once, for one second each Code for 1st digit
III 4 times, for one second each Code for 2nd digit
IV Once, for one second each Code for 3rd digit
V 3 times, short Code for error message repeated
