Parameter Settings
The BT300 requires some parameter settings to be changed for proper operation of
the Bypass Option (Conventional or Electronic) retrofit on an SED2 Bypass.
The parameter setting changes may be done using the keypad or the Siemens NET
Tool.
See the proper section for the configuration method you wish to use.
