voltage category III), Protective separation (overvoltage category II)
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)
