Muting Function - Reer MOSAIC Master M1 Installation And Use Manual

MUTING FUNCTION

The Muting function generates a temporary, automatic interruption of safety device 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)
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 (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) (barrier
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.
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.
Direction: The order in which the sensors are occupied can be set. 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 Close: 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.
