5.4.6.2 MUTING “L” operator
Figure 5-152 Sensor arrangement for “MUTING “L””
Figure 5-153 “MUTING “L”” operator
The MUTING operator with “L” logic enables the muting of the “Input” input signal to be per-
formed via the input of sensors “S1” and “S2”.
Key
S1, S2 Muting sensor pair, arranged in the danger zone
S, R Transmitter (S) and receiver (R) of the safety equipment (light grid)
T Transport goods (material flow from right to left)
! Danger zone
Prerequisite: the muting cycle can only begin when all sensors are at logic “0” and “Input”
is at logic “1” (light grid is clear).
