General system description - annunciator variants The fault annunciator is available in three different categories: • BSM-C: Basic version • BSM-P: Parameterisable version • USM: Annunciator with protocol interfaces The annunciators can be provided in 6 different sizes with 8, 16, 24, 32, 40 or 48 signal inputs. The signal inputs are arranged in groups of 8 alarms each. The sealed front contains 4 push buttons, bicolour-LED-displays (red/green) and slide-in pockets for labelling strips. The functions alarm acknowledgement, horn acknowledgement and lamptest are fixed assigned to the buttons for...

panel-mounted fault annunciator Further Settings • Collective report • Horn • Horn lock - static / output-parallel - retriggerable by subsequent alarm and manual acknowledgement - none BSM-P: Parameterisable version In addition to the characteristics of the basic version the BSM-P can be parameterised through a USB-interface and can be cascaded by additional annunciators. A description of the cascading functionality can be found at the end of this section. Parameterisation To allow for further application specific settings, every annunciator BSM-P can be parameterised by PC-software. In addition...

The different alarm sequences use different options for forming collective reports. In principle, the following variants may be used: Function static / input-parallel static / output-parallel static / dynamic / input-parallel static / dynamic / output-parallel dynamic static / input-parallel / resettable static / output-parallel / resettable Procedure The collective report is set with the first incoming alarm and resets with the last receding alarm. The collective report is set with the first incoming alarm. Once all alarms have receded and been acknowledged the collective report is reset. The...

PANEL-MOUNTED FAULT ANNUNCIATOR With the cascading functionality up to four devices can be grouped to an annunciating system by connecting the devices via CAN-Bus interface. 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. When creating an annunciating system, please note that the master device has to be bigger or equal to the slave devices. MSM-relay-modules cannot be connected to cascaded annunciators. General design of a cascaded fault annunicator system: 5 The parameterisation is done at once via the...

USM: Annunciator with protocol interfaces The USM resembles the BSM-P in general functionality. For communication with superior or inferior systems (e.g. SCADA or control systems) the USM is equipped with one or two communication cards. The communication cards provide the following interfaces: Card 1 (equipped as standard) • 1 x Ethernet / RJ45 • 1 x RS232 / pluggable terminal • 2 x USB-A • 1 x CAN-Bus / RJ45 • 1 x USB-B (factory interface) Card 2 (optionally equipped) • 1 x Ethernet / RJ45 • 1 x RS232 / pluggable terminal Through these interfaces the annunciators can be connected to third party...

PANEL-MOUNTED FAULT ANNUNCIATOR In this application example the USM processes and displays alarms that are retrieved from the IEC interface. Thus, a secondary wiring of the alarms is not SCADA System Protection Devices With the optionally available software license The USM provides an integrated web-server. Thus the parameterization can be done via network with all current web browsers. All annunciator and interface parameters are available on the web-server and can be parameterized through it. No additional software or special cables are required! Service-access and online-monitoring are additional...

Labelling Labelling of the annunciator is done by means of designation strips that can be inserted beneath the cover foil after removing the front frame. The designation strips with signal names can be created and printed directly from the parameterisation interface or generated manually from labelling strips in Word-format. A vailable Options The annunciators can be equipped with the following available options: 1. Internal relay-cards The optionally integrated relay cards (8 NO contacts each) are independent from the 4 function relays of the annunciator and can – dependent of the annunciator...

panel-mounted fault annunciator Available variants: * With the BSM/USM 32 and BSM/USM 48 devices 2 internal relays cards (which means 16 relays contacts) can be provided. 2. Redundant power-supply Independent from the primary power supply of the device a second, redundant power supply can be integrated into the fault annunciator. Two different voltage variants are available: The voltage level of the redundant power supply can be chosen independently from the voltage level of the primary power supply. Both primary and redundant power supply are included in the self-monitoring of the annunciator...
