MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC
204 8540780 • 10/07/2020 • Rev.38
MUTING FUNCTION
The Muting function generates a temporary, automatic interruption of electro-sensitive protective
device (ESPE) operation in order to permit normal transit of material through the guarded opening.
In other words, when the system recognizes the material and distinguishes between this and any
operator (in a potentially dangerous situation), it is enabled to bypass the safety device temporarily,
allowing the material to pass through the guarded opening.
MUTING OPERATORS (max number = 4 with M1, 8 with M1S)
"Concurrent" MUTING
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 chosen by the operator (or
S3 and S4 with material that is moving in the
direction opposite).
The MUTING operator with "Concurrent" 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 inputs are 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
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&S2 to S3&S4 and from S3&S4 to
S1&S2, if set to UP they can be occupied from S1&S2 to S3&S4 and if set to DOWN from
S3&S4 to S1&S2.
Muting Closing: There are two types, CURTAIN and SENSOR. If you select CURTAIN muting
closes when the input signal rises, if you select SENSOR it closes when the third sensor has
been cleared.
