Pulsed voltage supply and crossfault monitoring

For information about parameter setting and operating principles, refer to chapter Startup.

If crossfault monitoring is used for a safe digital input F-DI.., the following assignment between the sensor supply F-SS.. and the safe digital input F-DI.. must be adhered to:

• F-DI00, F-DI02 via the respective sensor to F-SS0.
• F-DI01, F-DI03 via the respective sensor to F-SS1.

Crossfault monitoring can be selected separately for each input.

If crossfault monitoring is not active (e.g. for sensors with OSSD output), the sensors can be supplied either from F-SS0 / F-SS1 or from another +24 V supply that has the same ground reference.

WARNING

Danger due to incorrect setting of the parameter connection type when connecting two-channel sensors. There is no redundancy or discrepancy check with the "one-channel" setting.

Severe or fatal injuries.

• When connecting two-channel sensors, you must set the parameter connection type to "two-channel (non-equivalent/equivalent)".

Only the connection variants shown below are permitted for safe applications! Also note the assignment of the connection variants of the safe digital inputs to the category structures pursuant to EN ISO 13849-1.
