9.4.7.2. MUTING "L"
The muting function is activated after the interruption of the sensors
S1 and S2 (the sequence is irrelevant) within the period defined by
the operator of between 2 s and 5 s.
The muting status ends after the opening has been cleared.
The MUTING operator with "L" logic makes it possible to mute the
input signal via the sensor inputs S1 and S2.
¨
Prerequisite: The muting cycle can only start if S1 and S2 are "0"
(FALSE) and the input is "1" (TRUE).
Parameter
Timeout (s): Sets the time within which the muting cycle is to be ended
from 10 s to infinite. If the cycle is not complete at the end of this
time, the muting is interrupted immediately.
With Enable: If selected, it is possible to enable or not enable the
muting function. Otherwise the muting function is always enabled.
Figure 179: L muting
There are two enable modes: "Enable/Disable" and "Enable Only". On the selection of "Enable/Disable" the muting cycle
cannot be started if "Enable" is set to "1" (TRUE) or "0" (FALSE), instead it is only activated with a rising edge. To deactivate
the muting, set "Enable" to "0" (FALSE). In this mode the muting is deactivated on a falling edge, irrespective of the state.
On the selection of "Enable Only" the muting cannot be deactivated. "Enable" must be set to "0" (FALSE) to make possible a
new rising edge for the next muting cycle.
Sensor Time: The
maximum time
(between 2 s and 5 s) between the activation of two muting sensors can be set.
End Muting Time: Defines the
maximum time
(between 2.5 and 6 s) that must elapse between clearing the first sensor
and clearing the hazardous opening.
After this time has elapsed, the muting function is at an end.
Blind Time: Should be selected if, for instance, it is known that after the end of the muting, objects may protrude beyond
the pallet and may occupy the light grid, as a result the input is set to "0" (FALSE). During the blind time the input remains
"1" (TRUE). The blind time can be between 250 ms and 1 s.
