Error display through flashing codes

The "Safetygate" 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 "Safetygate" 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 4 digits. The

digits are separated by a longer period without flashing. The entire sequence is constantly

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
