MUTING "L"
The muting function is activated after the in-
terruption of the sensors S1 and S2 (the se-
quence is irrelevant) within a period defined by
the user of between 2s and 5s.
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 sen-
sor inputs S1 and S2.
Prerequisite: The muting cycle can only
start if S1 and S2 are "0" (FALSE) and the
INPUT input is "1" (TRUE).
Parameters
Timeout (s): Sets the time within which the muting cycle is to be ended from 10 s to infi-
nite. If the cycle is not complete at the end of this time, the muting is interrupted imme-
diately.
With Enable: If selected, it is possible to enable or not enable the muting function. Other-
wise the muting function is always enabled.
There are two enable modes: „Enable/Disable“ and „Enable Only“. On the selection of „En-
able/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 "Ena-
ble" 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: Defines the maximum time (between 2 s and 5 s) between the activation of
two muting sensors.
End Muting Time: Defines the maximum time (from 2.5 to 6 seconds) that must elapse
between clearing the first sensor and clearing the hazardous opening.
After this time, the muting function is at an end.
Blind Time: Should be selected if, for instance, it is known that after the end of the mut-
ing, objects may protrude beyond the pallet and may occupy the light curtain, as a result
the INPUT input is set to "0" (FALSE). During the blind time the INPUT input remains "1"
(TRUE). The blind time can be between 250 ms and 1 s.
