"Input" LED lights up yellow: the signal switches from high to low at one input, while a
high signal remains on the other input (
partial operation
).
Remedy: Open both channels of the input circuit.

"Power/Fault" LED lights up red: Error message
Flashing codes for fault diagnostics are output to the "Safety Gate" or "Input" LED (see
Error display through flashing codes).
Remedy: Rectify fault and interrupt power supply.

"Lock" LED lights up red: Guard locking request is present, but guard locking has not
taken place.
This behaviour occurs, for example, when the safety gate is open or the actuator is not
within the response range or the holding force is too low.
Remedy: Rectify the cause (e.g. close safety gate), supply a low signal at input S31
and then supply a high signal again after at least 500 ms.

The switch-on delay after UB is applied.
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.
