MUTING OPERATORS (MAX. 4 WITH UG 6911.10, AND 8 WITH UG 6911.12/080
The 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.
„Concurrent“ MUTING
Parameters
Timeout (s):
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:
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 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.
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).
