The cones symbolize the sensing range of the sensors.
Figure 5-155 “MUTING “Seq”” operator
The MUTING operator with “sequential” logic enables the muting of the “I
NPUT” input signal
to be performed via the input of sensors “S1”, “S2”, “S3”, and “S4”.
Key
S1 First muting sensor before the safety equipment
S2 Second muting sensor before the safety equipment
S3 Third muting sensor after the safety equipment
S4 Fourth muting sensor after the safety equipment
S, R Transmitter (S) and receiver (R) of the safety equipment (light grid)
T Transport goods (material flow from left to right)
! 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).
