Datasensing SH4 STANDARD MUTING - T Muting (2 Signals;4 Sensors)

FUNCTIONS
50 SH4 STANDARD MUTING
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
12
activation delay between MUTING1 and MUTING2 must be greater than
response time and less than 4s.
.

bidirectional (T), four-sensors muting
NOTE: See “Response Times” on page 78.
NOTE: Muting operations is ceased as soon as the signal on MUTING1 or
MUTING2 goes low.
