BA PSEN sl­1.0p 1.1/1.1 VA/2.1/2.2
Function description
There is a high signal at safety outputs 12 and 22 if the following occur simultaneously:
}
The actuator is within the response range (safety gate closed) and
}
Inputs S11 and S21 are high and
}
Input S31 is high (control command for magnetic guard locking) and
} The holding force of the locking magnet has been tested successfully.
Safety outputs 12 and 22 are low if at least one of the following conditions are met:
}
The actuator is outside the response range or
} Inputs S11 or S21 are low or
}
Input S31 (control command for magnetic guard locking) is low or
}
The holding force of the locking magnet has not been tested successfully.
Signal output Y32
The signal output Y32 receives a high signal if the actuator is within the response range
(safety gate closed).
Feasibility monitoring for safety inputs S11 and S21
}
If one safety input switches from high to low, while the other safety input remains high,
an unequal status is displayed.
}
If this safety input switches back from low to high, while the other safety input remains
high, a feasibility error is displayed and a partial operation lock is triggered. The OSSDs
are switched off during the partial operation lock.
