Muting In Two Directions - Pilz PSEN sc M 3.0 08-12 Operating Manual

Project configuration
Muting means a temporary suspension of the safety function. For this reason, the muting
function must have a time restriction. When the muting sensors are activated and the mut-
ing state begins, an internal clock is started. If the muting sensors are still active after 10
minutes (status when delivered), the muting state is cancelled and the safety laser scanner
switches to a safe condition.
The time monitoring of the muting function can be set in PSENscan Configurator.

Inform staff of the
– hazard potential from the muting function,
– absence of protection during muting.
}
Mark the area that is protected by the safety laser scanner.
}
The muting inputs 1 and 2 cannot be activated simultaneously.
} A muting activation is not possible when the safety laser scanner is in a safe condition

Different conveyor speeds in the area of a
PSEN sc M 3.0/5.5 08-12 series should be prevented.
}
The muting sensor A1 and the muting sensor A2 must be connected to Muting 1.
The muting sensor B1 and the muting sensor B2 must be connected to Muting 2.
}
The muting state is shown by the muting lamp and in the display of PSEN sc M 3.0/5.5
08-12 series.
The muting lamp must be connected to the PSEN sc M 3.0/5.5 08-12 series and posi-
tioned so that the muting lamp is clearly visible form the whole danger zone.
}
Use a muting lamp with an LED lamp and a max. current consumption of 250 mA.
}
Indicate clearly visible near the protected area that there is no protection when the muting
lamp is lit.
}
The muting sensors have to positioned in a way that the muting area cannot be reached
while muting is active.

CAUTION!
Risk of injury due to loss of the safety function.
If time monitoring for the muting function is set to ∞, the muting function is
not cancelled until the muting sensors are no longer active.
This setting does not comply with the specifications of EN ISO 61496-1.
– Avoid a situation in which sustained muting is not detected.
