Blind Time: Only with Muting Close=Curtain, blind time is enabled when it is known that after a
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 ms to 1 second.
Sensors Time: Sets the maximum time (between 2 and 5 seconds) between activating two muting
sensors.
Minimum sensors time: If selected, allows the activation of Muting cycle only if a time >150ms elaps
between the activation of the sensor 1 and sensor 2 (or sensor 4 and 3).
MUTING “L”
The activation of the Muting function occurs following
interruption of the sensors S1 and S2 beam (the order does not
matter) within a time range from 2s and 5s decided 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 input = 1
(TRUE) (safety curtain free).
Parameters
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.
With Enable: When checked let the user the possibility of enabling or not enabling the Muting
function. Otherwise the Muting function is always enabled.
