Function description
The muting controller PMUT X1P is used for the temporary suspension of safety functions.
This allows objects to be transported into and out of a danger zone without adversely af-
fecting the safety function. When the supply voltage is applied the "POWER" LED will light.
The unit is ready for operation when the feedback loop Y1-Y2 and the input circuit (e.g. light
guard at S12 and S22 not interrupted) are closed. The muting sensors are not active.
} Start circuit S33-S34 is closed:
– Safety contacts 13-14/23-24/33-34 are closed, auxiliary contact 41-42 is open.
– Status indicators "Output", "OSSD CH.1" and "OSSD CH.2" are lit.
– A high signal is present at the semiconductor output Y32 (ESPE state).
– A high signal is present at the semiconductor output Y36 (switch state of safety con-
tacts)
} Input circuit is opened (e.g. light guard at S12 and S22 interrupted):
– Safety contacts 13-14/23-24/33-34 are opened redundantly, auxiliary contact 41-42
is closed.
– Status indicators "Output", "OSSD CH.1" and "OSSD CH.2" go out.
– A low signal is present at the semiconductor output Y36 (switch state of safety con-
tacts).
– A low signal is present at semiconductor output Y32 (ESPE state).
