Wiring test
A wiring test can be made after all peripheral devices are connected. We
recommend testing after configuration and settings are complete.
It provides the following functions:
•
Display read-only values for inputs.
•
Switching aggregates connected to the outputs, e.g. operating mode outputs,
heat demand, fault relay, etc.
During the wiring test, the application is deactivated.
•
The outputs are in a defined OFF state, and safety-related functions (e.g. smoke
extraction) are deactivated!
•
Communication with RXB/RXL room controllers is interrupted. No more defined
values are transmitted
During wiring test, both inputs and outputs are checked for the following errors:
•
Connection error (mixed up wires)
•
Position error (mixed up sensors or actuating devices)
•
Discrepancy between the type of connections made and the configuration of the
central control unit, e.g. Ni 1000 in place of active DC 0...10 V
