6. Diagnostic functions
6.1 Diagnostic-LEDs
The solenoid interlock signals the operational state as well as errors
through three coloured LED’s installed on the front side of the device.

6.2 Solenoid interlock with conventional diagnostic output
The short-circuit proof diagnostic output can be used for central
visualisation or control functions, e.g. in a PLC.
The diagnostic output is not a safety-related output.
Error
Errors, which no longer guarantee the function of the solenoid interlock
(internal errors) cause the safety outputs to be disabled immediately.
Any error that does not immediately affect the safe functionality of the
solenoid interlock (e.g. excess ambient temperature, safety output to
external potential, short circuit) will lead to a delayed shut-down (refer
to table 2).
After fault rectification, the sensor can be reset by opening and
relocking the relevant guard door. The safety outputs enable and allow
a restart. An interlocking chain must be permanently "locked" to enable
the reactivation.
Automatic, electronic locking takes place if more than one
fault is detected at the safety outputs or a cross circuit is
detected between Y1 and Y2. This means that normal fault
acknowledgement is no longer possible. To reset this type of
interlocking, the solenoid interlock must be isolated from the
power supply after elimination of the error causes.
Error warning
A fault has occurred, which causes the safety outputs to be disabled
after 30 minutes. The safety outputs initially remain enabled. This
signal combination, diagnostic output disabled and safety channels still
enabled, can be used to stop the production process in a controlled
manner. An error warning is deleted when the cause of error is
eliminated.
