Structure

The interlocking and guard locking system prevents the safety gates to the danger zone
from being opened while there is any hazard within the danger zone (machine movement,
voltage, ...).
The safety outputs may have a high or low signal, depending on the position of the actuator
and the signal path of safety inputs S31 and S41 (solenoid operation).
Gate open
Safety outputs 12 and 22
Under these conditions there is a high signal at safety outputs 12 and 22:
}
Actuator is detected and
}
Guard locking pin has successfully been activated (guard locking pin is in the locked posi-
tion)
If one of these conditions is not met, the signal at the safety outputs will be low.
}
Diagnostic input Y1
If a fieldbus module of the SDD is used, the diagnostic input Y1 is automatically activated
and data is read.
If no fieldbus module of the SDD is used, the diagnostic input Y1 must not be used.
}
Signal output/diagnostic output Y32
The status of the actuator is output. If a fieldbus module of the SDD is used, the signal
output/diagnostic output for the writing of data is activated.
