Troubleshooting
Error
Errors that no longer guarantee the function of the safety door switch (internal errors) cause the safety outputs to be disabled immediately.
Any error that does not immediately affect the safe functionality of the safety door switch (e.g. too high ambient temperature, interference potential
at the safety outputs, cross-wire short) will lead to a warning message, disabling of the auxiliary output and a delayed shutdown of the safety
outputs. (Refer to Table 2.)
After fault rectification, the Switch can be reset by opening and relocking the relevant guard door. The safety outputs enable and allow a restart. An
interlocking chain of the safety door switch must be "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.
To reset this type of interlocking, the safety door switch 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, auxiliary 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.
Table 1: Diagnostic information for the safety switch
The safety switch signals the switching condition as well as malfunctions via three coloured LEDs installed on the device.
*1.
After 30 min: disabling due to fault
*2.
Refer to flash code
*3.
Refer to Teaching.
