Figure 5-151 “MUTING “Con”” operator
The “MUTING” operator with “concurrent” logic enables the muting of the “I
NPUT” input sig-
nal to be performed via the input of sensors “S1”, “S2”, “S3”, and “S4”.
The muting function is activated following the interruption of sensors “S1” and “S2” (the
order is not important) in the parameterized time period between 2 s and 5 s (or “S4” and
“S3” in the case of material traveling in the opposite direction).
Parameters
Timeout (s) Enables a time to be set from 10 s to “unlimited”, within which the muting cycle must be com-
pleted. If the cycle has not been completed when this time expires, muting is immediately
interrupted.
With Enable If this parameter is selected, it is possible to activate or deactivate the muting function. Oth-
erwise, the muting function is always activated.
Enable Type There are two options for the enable type: “Enable/Disable” or “Enable Only”.
If the “Enable/Disable” parameter is selected, the muting cycle is only enabled by a rising
edge of the “E
NABLE” signal. The muting cycle is terminated at the latest by a falling edge at
the “E
NABLE” input.
If the “Enable Only” parameter is selected, the muting cycle is only enabled by a rising edge
of the “E
NABLE” signal. The muting cycle is not terminated by a falling edge at the “ENABLE”
input. For a new muting cycle to be performed, the “E
NABLE” signal must detect a rising
edge.
With Muting Out This parameter makes a muting output available at the function block, via which a muting
lamp can be connected.
Prerequisite: the muting cycle can only begin when all sensors are at logic “0” and “Input”
is at logic “1” (light grid is clear).
