"POWER/Fault" LED lights up red: Error message
Flashing codes for fault diagnostics are output to the "Safety Gate" and "Input" LEDs
(see Error display through flashing codes).
Remedy: Rectify fault and interrupt power supply.
Please note the different switch-on delay after U
B
is applied and after the recovery time of
the sensor and evaluation device.
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.
