FS input fault

FS – input error

If the safety option detects an error at a safe digital input, the affected safe digital input is switched to the safe state. If the affected safe digital input is parameterized as dual-channel, both inputs are switched to the safe state. In the FS-protocol, the bits of the affected safe digital inputs are set to "0" and the error bit is set to "1".

In addition, the corresponding error code is transferred for the FS input error that occurred.

INFORMATION

If a safe digital input is assigned to a safety sub-function via function assignment, then this safety sub-function is selected in the event of an FS input error.

At a safe digital input with detected error, the error must first be resolved and the safe state established before acknowledging the FS input error. In this way, a safety sub-function is not erroneously selected after acknowledgment of an FS input error.

FS – critical error

In the case of a critical error, the safety option is set to the safe state. Parameterization of the safety option is not possible. All safe digital inputs are switched to the safe state. In addition, the STO safety sub-function is executed without a delay. The sensor supply for the safe digital inputs is also switched to de-energized state. Active safe communication is suspended.

In addition, the corresponding error code is transferred for the critical error that occurred.

If the critical error was caused by the parameterization, you must start the safety option without safety key and then restore the safety option to its delivery state. You can then restart the safety option with safety key.

INFORMATION

Please note that the safety key may only be inserted or removed when the device is switched off.
