Troubleshooting
Error
Errors that, which no longer guarantee the function of the safety
door switch (internal errors) cause the safety outputs to be
disabled within the risk time.
After the rectification of the error, the error message is reset by
opening the corresponding guard door.
Error warning
The auxiliary output can also be used to detect clearance
variations between the safety door switch and the actuator in the
same way as the yellow LED.
An active fault is visualized by the red LED and causes the
auxiliary output to be disabled. The safety outputs are disabled
after a maximum of 30 minutes if the fault is not rectified. This
signal combination, auxiliary output disabled and safety channels
still enabled, can be used to stop the production process in a
controlled manner.
