5.5 Determining The Correct Radio Channel
The user requires system feedback to determine if the correct radio channel has been
reached.
Several methods are possible for that, including:
Feedback from the device into which PTM 215ZE is learned in
E.g. blinking a status light, toggling a connected load, moving a motor etc.
Feedback from a dedicated user interface
This could for instance instruct the user on the required key sequence and confirm correct
execution
It is the responsibility of the system designer to define a suitable feedback mechanism.
5.6 Radio Channel Storage And Return To Data Mode
If PTM 215ZE has been successfully set to the desired radio channel, then this radio channel
has to be stored and operation should return to data mode.
This is achieved by pressing any button contact other than the one used for entry into com-
missioning mode (and channel change). So if button contact A0 was used to enter commis-
sioning mode then pressing button contact A1, B0 or B1 will cause storing of the current
radio channel and return to data mode.
Failure to store the selected radio channel and to return to normal mode could cause acci-
dental reconfiguration of PTM 215ZE.
