The muting function is activated following the interruption of sensors “S1” and “S2” (the
order is not important) in the user-defined time period between 2 s and 5 s.
The muting cycle ends when the protective field of the electro-sensitive protective equip-
ment is clear (after enabling passage).
Parameters
Timeout (s) Enables a time to be set from 10 s to “unlimited”, within which the muting cycle must be com-
pleted. If the cycle has not been completed when this time expires, muting is immediately
interrupted.
If the value is set to “unlimited”, the “With Enable” input parameter is automatically activated.
With Enable If this parameter is selected, it is possible to activate or deactivate the muting function. Oth-
erwise, the muting function is always activated.
Enable Type There are two options for the enable type: “Enable/Disable” or “Enable Only”.
If the “Enable/Disable” parameter is selected, the muting cycle is only enabled by a rising
edge of the “E
NABLE” signal. The muting cycle is terminated at the latest by a falling edge at
the “E
NABLE” input.
If the “Enable Only” parameter is selected, the muting cycle is only enabled by a rising edge
of the “ENABLE” signal. The muting cycle is not terminated by a falling edge at the “ENABLE”
input. For a new muting cycle to be performed, the “Enable” signal must detect a rising edge.
With Muting Out This parameter makes a muting output available at the function block, via which a muting
lamp can be connected.
Sensor Time A maximum time (2 to 5 s) can be parameterized that may elapse between the activation of
both muting sensors (S1 and S2).
End Muting Time The maximum time (from 2.5 to 6 s) that may elapse between the enabling of the first sensor
and enabling dangerous passage can be entered. The end of the muting function is initiated
after this time has elapsed.
Blind Time The “Blind Time” parameter should be activated if, at the end of the muting cycle, objects
may protrude which occupy the light grid and set the “I
NPUT” input signal to logic “0” (e.g.,
material protruding from a pallet, etc.). During the “Blind Time”, the “I
NPUT” input signal is in-
ternally overwritten with logic “1”. The “Blind Time” can be parameterized between 250 ms
and 1 s.
