    • In normal operation the SED2 is receiving the setpoint over the analogue input 1, e.g. from a BAC, e.g. DESIGO PX. • In case of fire the fire control panel signals this to the SED2, it is going in the ESM mode and the setpoint is still coming over the analogue input.

    Commissioning Wizard for Essential Service Mode Introduction Up to now the SED2 drives have been commissioned over the BOP/AOP respec- tively over EasyComm which is a parameterisation and monitoring tool for the SED2 family. This may be inefficient particularly with more complex applications such as ESM and bigger projects.

    Essential Service Mode (in-depth in- formation) • With V1.40 and higher, all SED2 errors and warnings will be ignored, the excep- tion being hard errors, such as F0001, F0002, F0003, F0022 and F0023. These hard errors can not be ignored since they could lead to the destruction of the VSD.

    SED2 will acknowledge, restart and ignore all ‘soft faults’ and attempt to acknowl- edge and restart any ‘hard faults’. If a hard fault is still present, then the SED2 will trip and attempt again indefinitely or until the SED2 is destroyed.
