Function description
The high signal is maintained if the following conditions are met simultaneously
} [1] in the timing diagram
– Actuator is within the response range and
– There is a high signal at 31/Y1 and
– The holding force of the locking magnets was achieved within t
or
}
[4] in the timing diagram
– Actuator is within the response range and
– There is a low signal at 31/Y1.
At the signal output Y32 the signal switches to low if
}
The actuator leaves the response range (safety gate open) (see [3] in the timing diagram)
or
}
The holding force could not be achieved after t
gram). In this case, the signal at the signal output can only switch back to high if
– There is a low signal at input 31/Y1 for at least 500 ms and
– a high signal is transmitted afterwards.
}
Signal output/diagnostic output Y32 in SDD mode
If an SDD fieldbus module is used, the diagnostic input Y1 is used for SDD communica-
tion.
} Input 31/Y1
If an SDD fieldbus module is used, the input 31/Y1 is used as a diagnostic input Y1 and
data is read.
If no SDD fieldbus module is used, the input 31/Y1 is used for activating the guard lock-
ing.
Plausibility monitoring for safety inputs S11 and S21
}
If the signal at a safety input switches from high to low, while the other safety input re-
mains high, an unequal status is displayed.
}
If the signal at this input switches back from low to high, while a high signal remains at
the other input, a plausibility error is displayed and a partial operation lock is triggered.
The OSSDs are switched off during the partial operation lock.
A switch to a high signal will only lead to error-free safety switch operation if both inputs
had a low signal simultaneously. From this moment on, the switch to high signal may occur
