T Muting (2 Signals/4 Sensors) - Datasensing SH4 STANDARD MUTING Product Reference Manual

FUNCTIONS

T muting (2 signals/4 sensors)

The activation of the Muting function occurs as a result of a rising edge on MUTING1
and MUTING2 inputs (the order depends on material direction). As reported in figure
below T
