3 Mounting and installation
Notes with regard to the sample circuit:
– In the input circuit for the input devices for the safety request S1, the CAMC-G-S3 in T1 detects
cross-circuits for the acknowledgement pushbutton S2 and for the Start button S3.
– Actuating the Start button S3 commences the restart.
– The motor controller T1 must forward the safety request via DOUT40A/B to the motor controller T2,
which then also reacts to the safety request.
– The motor controller T2 indicated a safety request to the motor controller 1 as feedback.
– The acknowledgement contacts C1, C2 of T1 and T2 are connected in series, and the signal should
be polled via the controller. If a safety request has been made, then the controller should react in an
appropriate manner (e. g. in the case of SLS, the setpoint values should be reduced, while, in the
case of SS1, the controller enable should be retracted).
– 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 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.
