Sequential" Muting - Reer MZERO Installation, Use And Maintenance Manual

Enable Type:
There are two Enable modes: Enable/Disable and Enable Only.
•
If "Enable/Disable" is selected the Muting cycle cannot start if Enable is stucked at 1 (TRUE)
or 0 (FALSE). It is only activated with a rising edge of the signal. On the other hand the
falling edge disables Muting regardless of the current condition.
•
If "Enable Only" is selected the Muting function cannot be disabled. It is mandatory to set
the "Enable" input to 0 (FALSE) in order to reset this command for a new 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
The end of this time determines the end of the Muting function.
Blind Time: 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.

"Sequential" MUTING

The activation of the Muting function occurs following
sequential interruption of the sensors S1 and S2,
subsequently S3 and S4 sensors (without time limit). If the
pallet proceeds in the opposite direction the correct
sequence is: S4, S3, S2, S1.
The MUTING operator with "Sequential" logic
performs muting of the input signal through
sensor inputs S1, S2, S3 and S4.
➔
Preliminary condition: The Muting cycle can
only start if all the sensors 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.
Enable Type:
There are two Enable modes: Enable/Disable and Enable Only.
•
If "Enable/Disable" is selected the Muting cycle cannot start if Enable is stucked at 1 (TRUE)
or 0 (FALSE). It is only activated with a rising edge of the signal. On the other hand the
falling edge disables Muting regardless of the current condition.
•
If "Enable Only" is selected the Muting function cannot be disabled. It is mandatory to set
the "Enable" input to 0 (FALSE) in order to reset this command for a new Muting cycle.
Direction: This let the user to choose the order in which the sensors are occupied. If set to BIDIR
they can be occupied in both directions, from S1 to S4 and from S4 to S1, if set to UP they can be
occupied from S1 to S4 and if set to DOWN from S4 to S1.
