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

L muting (2 signals/2 sensors)

The activation of the Muting function occurs as a result of a rising edge on MUTING1
and MUTING2 inputs. As reported in figure below T
ING1 and MUTING2 must be greater than response time and less than 4s.
NOTE: See "Response Times" on page 78.
T is measured and then multiplied by 2 to calculate the muting timer. Muting opera-
12
tions is ceased when 2xT
If MUTING2 input goes low before MUTING1 muting is ceased immediately. Muting is
optionally ceased also when light curtain is free before the timer expires (Muting stop
condition parameter).
