Non-equivalence Monitoring The non-inverted and inverted signal lines of each safety track (A vs. A inv. and B vs. B inv.) must have non-equivalent signal levels at all times. In state transition, very short periods of time (some microseconds) are permissible in which both lines have same logical signal level. A dangerous error occurs when this short period of time is exceeded. Trigger level Outputs Linedriver RS422 Output level High >2.5 V (I = -20 mA) Output level Low <0.5 V (I = 20 mA) Load High <20 mA Load Low <20 mA Outputs Push-pull short-circuit proof Output level High >UB -3 V (I = -20 mA) Output level Low <0.5 V (I = 20 mA) Load High <20 mA Load Low <20 mA Line break detection Make sure none of the signal cables A, A inv, B, B inv. is high-impedant. The encoder will utilize the high-impedant status of the safety tracks A, A inv., B, B inv. to output an error message. Safe stop In case of missing state changes in at least one of the signals A, A inv., B, B inv., the customer has to ensure shaft standstill by means of a second, independent safety precaution within an acceptable amount of time depending on the facility.

If not, it is a fatal error. Safe rotational direction The phase shift of the safety relevant incremental signals A vs. B and A inv. vs. B inv. has to be monitored. A dangerous error occurs when exceeding the given tolerances. Compliance to the defined rotational direction has to be monitored as well. 2 Incremental encoders Solid shaft with clamping or synchro flange SIL2/PLd approval GI357 Output signals Terminal assignment Clockwise rotating direction when looking at flange.
