General system description - annunciator variants The fault annunciator is available in three different categories: • BSM-C: Basic version (starting from version 3.4) • BSM-P: Software-parameterisable version (starting from version 3.4) • USM: Annunciator with communication interfaces (from version 4.4, delivery from November 2023) The fault annunciators are offered with 8, 16, 24, 32, 40 or 48 signal inputs. The signal inputs are combined in groups of 8 alarms each. Each group is assigned to an slide-in pocket for individually created labeling strips. The closed front panel includes 4 buttons,...

BSM-C: Basic version In the basic version, configuration of the annunciator is done by DIP-switches. The following settings can be done: • Alarm sequence (first-up, no-first-up or operation indication) • NO- or NC-principle of the inputs cardwise (8 inputs) • Master/slave configuration and assignment of address for cascaded annunciator system • Horn triggering by subsequent alarms The function inputs, push buttons and function relays have the following fixed functions: • Function input 1 - external horn acknowledgement • Function input 2 - external acknowledgement • Function input 3* - external...

1. Channel-specific parameters (separate setting possible for each signalling channel) • Signal name (labelling) • Operation indication (status indication) or fault annunciation • NO- or NC-principle for each signal input • Debouncing delay • Alarm delay • Defluttering • Possible assignment to collective reports 1, 2 or 3 • Horn triggering (none, with or without lock see section horn triggering below) • Colour for displaying status or alarm 2. Alarm sequence (can be composed of the following components) • First-up or no-first-up alarm • 1- or 2-frequency-flashing or status indication • Colour...

BSM-P and USM have 2 horn functions. The parameterization can be used to define which group alarms or non-grouped alarms control the respective horn functions. In a second step it can be set which relay is controlled by a horn function. Additionally it can be parameterized whether the horn function 1 controls the internal horn. Internal horn For the horn function the following parameters are settable: 5In case of conflicts between the settings for horn activation and horn priority acknowledgement, the setting for the horn priority acknowledgement setting that is valid for all alarms always prevails....

BSM/USM In addition, the mute function can be used. After activation of this function by a parameterized button or a parameterized function input, the horn is not triggered or is automatically acknowledged after a parameterizable time. Furthermore, the horn control is deactivated in the "Unmanned operation" state. 6. Buttons and functional inputs The following functionalities are assignable for the 4 buttons and 2 functional inputs. Multiple assignments are possible: • Acknowledgment lamps Group*) 1,2, 3 or unassigned alarms • Reset Group*) 1, 2 , 3 or unassigned alarms • Acknowledgement Horn...

Produktbezeichnung BSM/USM Cascading With the cascading functionality up to four devices can be grouped to an annunciating system by connecting the devices via the systembus provided at the CAN-Bus sockets. One device works as “master” and the connected devices work as “slave”. Thus systems with up to 192 signal inputs (4*48) can be realized. Thus, the connected devices will be processing as a virtual compound annunciator with common signalling (alarm sequence, forming of collective reports and horn triggering). Acknowledgement as well as output of the collective reports and horn triggering can...

Second network interface (optionally) • LAN - Ethernet / RJ45 (Protocol interface as well as diagnostic and parameterisation) alternatively • Optical interface multimode 50-62.5 / 125 μm @ 1300 nm; Connector LC-duplex (according to standard IEC 60874-13) (protocol interface) 1. Protocol interfaces With the help of these interfaces, the annunciators can be connected to third party systems by use of the following protocols: • Modbus RTU/TCP (annunciator is Modbus-slave) • IEC 60870-5-101 (annunciator is IEC-server) • IEC 60870-5-104 (annunciator is IEC-server or client) • Optionally IEC 61850 (annunciator...

4. Mirroring of single alarms In this application example, the USM48 is used to signal faults that are "collected" by various devices via the IEC interface. An additional wiring of the individual fault alarm contacts is therefore not necessary. Central visualisation for "mirrored information" Acquisition devices In larger plant areas and complex processes, important individual states from the field are often required at central points or control rooms. In classical systems, 1:1 relays are used, which means a high amount of wiring. With USM fault reporting systems this effort can be greatly reduced....
