Category 3 wiring diagrams (redundant inputs and outputs): recommended applications
Connection of 4 sensors with dual contacts Connection of 4 sensors with dual contacts for existing installations
The states of all the contacts in the input circuit are read by the PLC. The
consistency test carried out by the PLC program on the input contacts enables
it to signal and locate precisely the faulty contact(s).
When using less than 4 dual contacts, the input terminals not in use must be
linked. For example, if contacts S0 and S4 are not in use, a bridge is required
between terminals 14 and 12 and terminals 13 and 15.
Suitable for use with existing wiring; with one contact on the safety module and
one contact for diagnostics, this wiring enables global reading of the state of
contacts S4 to S7 and individual reading of contacts S0 to S3.
The consistency test carried out by the PLC program on the inputs enables it to
signal any inconsistency with partial location of the fault.

Not all faults are detected. A short-circuit on a pushbutton or limit switch is not
detected.
When using less than 4 single contacts, the input terminals not in use must be
linked.
For example, if contact S5 is not in use, a bridge is required between terminals
10 and 12.
The connection of safety relay outputs in series enables diagnostics for up to
32 single or dual contact pushbuttons or limit switches. The number of modules
connected in series is limited by the number of slots available on the
TSX Micro PLC.
