The closing- and opening sequence of the release signals as well as of the safety relay must be consid-
ered in order to assure a faultless operation of the drive.
Sequence diagram of the safety relay
Baumüller-devices of the series BUM 6, BUS 6 and BKH, which are made with one safety relay (option-
al), comply with the requirements of the category 3 (EN 954-1) for the safety-relevant using “protection
against unexpected starting”, if the configuring and installation instructions are complied with.
Before the commissioning of the machine, in which the converter with the safety relay is built in, the safe-
ty function “protection against unexpected starting” must be checked. For that purpose a safety device
must be executed (for example door contact). The motor must now be zero-torque.
If the reliability performance of the “protection of unexpected starting” once has been determined, then
this safety function of the converter doesn’t have to be checked by an external monitoring, as the device
checks itself on possible errors and if necessary displays a message as well as turns off the drive.
