3 Mounting and installation
Notes with regard to the sample circuit:
– In the input circuit for the S1 switches, the safety module CAMC-G-S3 detects cross-circuits for the
acknowledgement pushbutton S2 and for the Start button S3.
– Actuating the Start button S3 commences the restart.
– If the safety module CAMC-G-S3 detects a violation of a safety condition or an error is pending, e. g.
in the connection wiring, it will indicate a malfunction. The error is acknowledged via the acknow­
ledgement pushbutton S2.
– The inputs DIN42A/B must be configured in such a way that they monitor the switching on and off of
the control block V1. Series connection to the protective contacts 41/42 of the contactors K1 and
K2 is not possible, as this is not possible with the inductive proximity switches used.
– The acknowledgement contact C1, C2 should be polled via the controller. If a safety request has
been made, the controller enable should be cancelled.
– The input circuit has a 2-channel structure, which is suitable for category 4.
– Additional measures are required according to the scope of application and the safety concept of
the machine.
