Changing Addresses; Deactivating / Reactivating Bus Components (Replacing Faulty Sensors) - Record DFA127 Instructions Manual

13.2.5

Changing addresses

The address must be changed if a wrong position has been assigned by mistake to a sensor
while the system has already been activated. The correct procedure is explained in the fol-
lowing example:
Example of wrong addressing:
Inside-RAD 290 → correct addressed as AKI 1
Outside-RAD 290 → wrong addressed as AKI 2
Consequently the operating mode "One-Way" does not work. Addressing must be modified.
Procedure:
Disconnect Outside-RAD 290 from bus
Address Inside-RAD 290 as AKA 1
Connect sensor to bus again
Deactivate no longer existing sensor AKI 2 with FPC in menu SERVICE STG / PARAME-
TER / CAN-BUS
Newly addressed sensor AKA 1 is automatically detected and activated.
13.2.6

Deactivating / reactivating bus components (replacing faulty sensors)

In the event of a sensor being faulty and must be replaced, the defective unit must only be
deactivated if a replacement is not immediately available.
Otherwise, the replacement must be addressed in the same way and then be connected to
the bus. Subsequently, a learning cycle must be performed for this sensor.
Procedure for deactivating:
▪ Disconnect defective or superfluous sensor from bus.
▪ Select this sensor with FPC in menu SERVICE STG / PARAMETER / CAN-BUS and de-
activate it.
