Connector coding

A series of coding elements ("coding sliders") are supplied with each Terminal Module TM15.
Connector coding
1. Insert at least one coding slider at the required position.
2. Remove the associated coding lug at the connector.
Figure 6-6
To avoid wiring errors, unique coding patterns must be defined for the connectors X520, X521
and X522.
Possible patterns:
• 3 connectors on one component are encoded differently (i.e. X520, X521 and X522).
• Different component types are encoded differently.
• Identical components on the same machine are encoded differently, e.g. several TM15-type
components.
