WARNING!
Potential loss of safety function due to implausible signals from the
proximity switch
Depending on the application, serious injury or death may result.
– Make sure that the proximity switches are installed as described in
the operating manual and that only those combinations described in
the signal characteristics table are used.
– Appropriate installation measures should be taken to prevent a for-
eign body coming between the signal encoder and the proximity
switch. If not, the foreign body could cause invalid signals.
– Please note the values stated in the sensor's technical details.

For a full configuration, the maximum frequency of the sensors you are using must be
entered in the PNOZmulti Configurator (see sensor's data sheet).

Encoder
}
The following encoders can be used:
– TTL, HTL (single-ended or differential signals)
– Sin/Cos 1 Vss
– Hiperface®
}
The encoders can be connected with or without Z index (0 index).
}
The cables used to connect the encoders must be shielded (see connection diagrams
in the chapter entitled "EMC-compliant wiring").
}
A proximity switch can also be connected to track Z to monitor for broken shearpins.
Please note:
Broken shearpin monitoring only becomes active when
– The minimum speed is exceeded
and
