CERTUS Installation Manual
Muting “L”
The activation of the Muting function occours
following interruption of the sensors S1 and
S2 beam (the order does not matter) within
a time range from 2s and 5s decide by the
operator. The state of the Muting ends after
the liberation of the guarded opening.
The Muting operator with “L” logic performs
muting of the input signal through sensor
inputs S1 and S2.
⇒
Preliminary condition: The Muting
cycle can only start if S1 and S2 are
0 (FALSE) and the inputs are 1 (TRUE)
(barrier free).
Timeout (sec): Sets the time, between 10 secs and unlimited, within which the Muting cycle
must end. If the cycle is not complete at the end of this time, Muting is immediately
discontinued.
Enable: If selected it enables the possibility of enabling or not enabling the Muting function.
Otherwise the Muting function is always enabled.
There are two Enable modes: Enable/Disable and Enable Only. If Enable/Disable is selected
the Muting cycle cannot start if Enable is fixed at 1 (TRUE) or 0 (FALSE) but is only activated
with a rising edge. To disable muting, set Enable to 0 (FALSE). In this mode the falling edge
disables Muting regardless of the condition. If Enable Only is selected Muting cannot be
disabled but Enable must be set to 0 (FALSE) in order to enable a new rising edge for the
next Muting cycle.
Sensors time: Sets the maximum time (between 2 and 5 seconds) between activating two
muting sensors.
End of Muting time: Sets the maximum time (from 2.5 to 6 seconds) that must elapse between
the release of the first sensor and the release of guarded opening.
The ends of this time determines the end of the Muting function.
Blind timer: Enabled if you know that after the complete transition of the pallet (muting cycle
close) some protruding objects could still occupy the light curtain and send the input to 0
(FALSE). During blind time the input remains 1 (TRUE). Blind Time can range from 250 msecs
to 1 second.
