ZZ) 2 General notes This operator s manual describes the function and handling of the basic-fault annunciator BSM and requires general knowledge about alarm sequences. For secondary information we refer to the following EES documentations SM-MA-ZI-UK MSM-RM-DB-UK - Description of the reporting procedures of EES-fault annunciators - Description of MSM-relay modules The operator s manual applies to several device types. It is possible that single device features are described which don t apply to your device. The contents of the documentation were examined in agreement with the described hard and software. Deviations nevertheless cannot be excluded so that we don t take on any liability for the complete correctness. Page 3 of 23
2.1 Used symbols The following symbols are used in this document: Safety instruction This symbol marks warnings, prohibitions and directions relating to hazards. It is essential that they are observed and obeyed. Additional note This symbol indicates additional information. Important section This symbol indicates particularly important information. Cross-reference This symbol refers to diagrams and to other locations within the document. 2.2 Used definitions New value reporting with 1 frequency flashlight. In case of new value reporting all messages are treated equal. If a signal lines up with a period which is longer than the response delay, the accompanying LED flashes. Horn and collective report are triggered, the message stored. All incoming messages are indicated with flashing light. Already gone, but not yet acknowledged messages are indicated by flashing light up to the acknowledgment. Now pressing the buttons for horn and acknowledgement, the horn relay falls off and the flashing light changes into steady light provided that the message still lines up. If the message is not present any more, the LED goes out. New value reporting with 2 frequency flashlight. A message can be indicated in a slow and fast flashing light. When a signal lines up with a period which is longer than the response delay the accompanying LED flashes fast. Horn and collective report are triggered and the message stored. All incoming messages are indicated with a fast flashing light. Messages already cleared but not yet acknowledged, are indicated by fast flashing light up to the acknowledgment. If the acknowledgement buttons for horn and fast flashing light are pressed now as long as the message still lines up, the horn relay falls off and the flashing light indication changes into steady light. If the message is removed and therefore no longer present, the LED goes out automatically. If the message is no longer present when pressing the acknowledgement buttons for horn and fast flashing, the corresponding LED begins to flash slowly. In this case the LED goes out only by pressing the acknowledgement button for slow flashing. First value reporting Unlike the new value reporting only the message arriving at first is indicated by first value reporting as a current message. All further messages which arrive up to the acknowledgment of every message are indicated as present and already acknowledged. Only after all messages have gone and acknowledges and therefore the collective report doesn t line up any more either, a message can be allocated and reported as first value again. The first value reporting can be combined with 1 or 2 frequency flashing light. Response delay time: Is the time period with which a signal must be lined up to be allocated by the fault annuciator as one. Signals with a shorter duration are ignored. Page 4 of 23

The BSM devices must not be opened or subjected to improper modification! 2.4 Correct and proper usage The fault annunciator is intended exclusively for the applications described in these operating instructions. Any other usage can be hazardous and is forbidden. The manufacturer cannot be held liable for the consequences of improper use of the BSM devices or for any application that does not accord with the contents of these operating instructions. 2.5 Device description 2.5.1 Construction of the BSM-annunciator The basic fault annunciator BSM for panel mounting is manufactured into 4 variants with 8, 16, 32 or 48 message inputs. The sealed front area contains 4 buttons and LED displays. The fault annunciator is built up into groups to 8 messages each. The essential functions of the fault annunciator are adjustable in the standard variant by DIP switches. Customdesigned alarm sequences can be realized factory set. The fault annunciator also can optionally be obtained with a connectivity for external relay modules and in a software parameterizable variant. Page 5 of 23
Depending on size, the fault annunciator includes the following functional components: Name Equipment Dimensions H x W x D [mm] BSM08 BSM16 BSM32 BSM48 Reporting inputs Reporting groups LED colours Buttons Function inputs Relay outputs Collective report 8 reporting inputs 4 buttons 2 function inputs 4 relay outputs 16 reporting inputs 4 buttons 2 function inputs 4 relay outputs 32 reporting inputs 4 buttons 2 function inputs 4 relay outputs 48 reporting inputs 4 buttons 2 function inputs 4 relay outputs The fault annunciator features reporting inputs that can be configured for different voltages and can be pre-processed. All 8 inputs of a reporting group can be configured together via DIP switches for normally open or normally closed contacts. 8 reporting inputs are consolidated to form a reporting group featuring 8 LED displays and a common label pocket. red, green, yellow, white or blue (mixed configuration available on request) The function of the four buttons that are integrated in the front panel depends on the implemented reporting procedure (e.g. message acknowledgement, delete, lamp test etc.) The two function inputs of the fault annunciator are used according to the selected reporting procedure, e.g. external acknowledgement. 1 x live contact 3 x message-specific function (e.g. collective report 1, collective report 2, horn etc.) The function of the collective report depends on the reporting procedure and is specified in the type data sheet.

DIP switches Relay modules Self-monitoring Softwareparameterising 2.5.2 Signal processing The following settings can be selected by DIP switches in the basic variant Function of collective report (standard / inverted) Horn control (subsequent alarm signal will trigger horn again / not again) Reporting procedure 1 or 2 Open circuit working or closed circuit working in common for all 8 inputs of a reporting group Maximal 6 external relay modules installed on a DIN rail can be connected to the optional interface CAN bus. These modules enable incoming messages to be relayed in parallel with inputs or outputs (PCS contacts). More detailed information may be found in the data sheet MSMRM. The fault annunciator features integrated self-monitoring signalling fault-free function via LED and relay contact. The fault annunciators can optionally be ordered in a version parameterisable with a PC program based on Windows. Transferring the parameters to PC is done via connection between RS-232 COM-port and service- and parameterisation interface of the BSM. Following parameters can be adjusted: Reporting sequence with single- or double frequency flashing light Horn priority acknowledgement Collective report statically or dynamically Assignment of external lamp test input on available relay output Inputs configurable for operating- or closed-circuit current per each Response delay adjustable per input between 5 ms und 60 s Free assignment of the inputs to the two collective reports Automatic horn acknowledgement adjustable (horn duration time 1... 250 s) The functional specification of a fault annunciator includes signal processing, which is structured in three groups: Reporting procedure Formation of collective reports Horn control Page 7 of 23
2.5.2.1 Reporting procedures One of the two reporting procedures deposited in the BSM can be selected by DIP switch. In the following the most required reporting procedures are listed. new-value reporting with single flashing light and single acknowledgement first-value reporting with single flashing light and single acknowledgement Which of the reporting procedures in the special fault annunciator is available, depends on the respective variant of the BSM. Many more sequences are applicable by using the software parameterizable version. For detailed information please request our separate description of the reporting procedures. 2.5.2.2 Collective report The different fault reporting procedures use different options for forming collective reports. In principle, the following variants may be used: Name static / input parallel static / output parallel static / dynamic / input parallel static / dynamic / output parallel dynamic Procedure The collective report is set with the first incoming message and sent with the last outgoing message. The collective report is set with the first incoming message. Once all messages have been sent and acknowledged the collective report is deleted. The collective report is set with the first incoming message. For each further report, the collective report is cancelled for approx. 0.8 s and then set again. Once all messages have been sent, the collective report is deleted permanently. The collective report is set with the first incoming message. For each further message, the collective report is cancelled for approx. 0.8 s and then set again. Once all messages have been sent and acknowledged, the collective report is deleted permanently. The collective report is activated for approx. 0.8 s with each incoming message. Page 8 of 23
2.5.2.3 Horn triggering Function Name Meaning Horn excitation (can be set via DIP switch) Horn acknowledgement retriggerable not retriggerable manual (continuous tone) automatic (pulse tone) 3 Assembly and installation manual with acknowledgement Page 9 of 23 The horn is retriggered by new incoming messages, even if messages are already present. The horn is retriggered for new incoming messages only if no messages are already present. The horn is acknowledged manually via a key or function input. The horn is acknowledged automatically according to the set time. The horn is acknowledged together with the lamp acknowledgement via the acknowledgement button. There is no special horn acknowledgement. 1. Unpack all the fault annunciator s devices, and check them for transport damage. Report any transport damage immediately to the responsible carrier.

The fault annunciator is operational. 4 Configuration of BSM annunciator per DIP-switch 4.1 Standard variant without external relay modules At delivery the fault annunciator is pre-parameterized and therefore in most cases easy to adjust with the attached DIP-switches on the backside for the respective application. The meaning of the DIP-switches for the respective variant can be taken out of device configuration sheet (document MSM-BSM-GK-UK). The following settings can generally be chosen: Function of the collective report (s) (standard/inverted) Horn triggering (subsequent message triggers horn again/not again) Choice of the reporting sequence (1 or 2) Processing of 8 inputs to a common reporting group (Open or closed circuit working) common configuration of all 8 inputs of one input array 4.2 Standard variant with external relay modules A maximum of 6 MSM relay modules can be attached to the fault annunciator in this variant. The relay modules are mounted on DIN rail and connected with the BSM over system cables. Relay modules make it possible to pass on lined up messages either input- or output parallel (for use of PCS-contacts). Page 10 of 23 1

5 Parameterization of the fault annunciator per PC By using the parameterizable variant the fault annunciator can be adjusted most flexible to arbitrary applications. Therefore additional parameters are modificable as follows: Reporting procedures Processing of inputs Horn triggering Assignment of buttons and functional inputs Control of functional relays The construction of the parameter file is done confortable by the enclosed PC-program based on Windows and is loaded in the fault annunciator via the connection cable available as accessory. In the following context the parameter setting possibilities of the program are described. The window of the parameter setting program is divided in 7 functional sections : 1 Device selection 2 Reporitng procedures 3 Processing of the inputs 4 Assignment of buttons and functional inputs 5 Functional relays 6 Progress window of data communication to BSM 7 Button-block Page 13 of 23 6 1 2 3 4 5 7
5.1 Device selection After starting the program at first the respective fault annunciator has to be selected. 5.2 Reporting sequence Two reporting procedures can be realised by the BSM with one assigned collective report per each. Every input will then be assigned to these reporting procedures and corresponding collective reports. For adjusting the reporting procedures flexibly to the respective requirement, they are build up by single components. Description Selection possibilities Selection for function 1/2 frequency 1-frequency 1-frequency-flashlight reporting sequence 2-frequency 2-frequency-flashlight reporting sequence First value/ New value upon selection Setting according to position First value / New value steadylight - steadylight (2-frequency) New value message with 2-frequency-flashlight and double acknowledgement (flashlight-steady light-steady light) Operating fault annunciator State indication steady light (only BSM 16) First value / New value annunciator New value annunciator New value First value annunciator First value annunciator First value annunciator group parallel According to DIP-switches Page 14 of 23 For both reporting sequences there is only one common first value determined acc. to DIP-switch-setting ( Section Configuration of the fault annunciator)
Collective report not inverted standard inverted inverted acc. to DIP-switch acc. to DIP-switch-setting ( Section Configuration of the fault annunciator) Output static / output parallel Output of collective report static / dynamically / input parallel static / dynamically / output parallel dynamically ( Section Collective report ) Example: First-up message with 1-frequency flashlight and single acknowledgement Horn retriggerable on follow-up message The collective report is set by the first upcoming message. Only if all messages are gone and are acknowledged, the collective report is deleted. Settings: 1/2 frequency reporting sequence - 1-frequency Reporting sequence - First-up / New value acc. to selection First-up / New value - First-up annunciator Horn triggering - retriggerable Collective report - not inverted Output - statisch / ausgangsparallel Detailed information of reporting sequences and signal processing can be taken from the seperate datasheet SM-MA-ZI-UK. 5.3 Input processing Within the input processing the features and functions of the following components are defined.: Message inputs and the assignment to the reporting procedures Functional inputs Labelling for messages and buttons Horn control 5.3.1 Message inputs After the device selection the respective available inputs groups (i.e. for the BSM 16 e.g. 2 input groups) are released to edit. For every group (8 inputs per each) can be decided, if the DIP-switchsetting or the software parameter setting is authorative for message processing. Page 15 of 23
In the next part of the dialog the settings can be taken for every single message listed in the following table. Description Selection possibilities Selection for functions Text for module labelling 20 characters Text to print labelling strips later on Meldungstyp Operating message State indication steady light Fault message Fault message acc. to selected reporting procedure Normally open / Normally closed Normally open Applying a voltage triggers a message. Normally closed Dropping off a voltage triggers a message. Response delay 5 ms... 60 s Time period of a message has to line up until being registered Activates collective report Collective report 1 Reporting procedure and collective report 1 Collective report 2 Reporting procedure and collective report 2 Horn is activated as Collective report 1 and 2 Horn without locking Horn with locking No horn triggering Page 16 of 23 Collective report 1 and 2 Within this selection, both reporting procedures should be identical, otherwise the message will be assigned to the reporting procedure with the highest priority. Message is not assigned to a collective report, however to the first reporting sequence Horn can always be acknowledged Horn acknowledgement is only possible Message does not trigger horn.
With the buttons copy dataset or paste dataset the settings of a message input can be transfered to another input.. On the right next to the labelling texts for the messages the assignment of labelling texts for the buttons can be made. The text should not consist of more than 5 characters. 5.3.2 Functional inputs In the lower part of the dialog the following specifications are to be set: Response delay (5 ms... 60 s) Normally open or normally closed 5.3.3 Horn acknowledgement In the last part of this section the type of horn acknowledgement is to be set. Manual acknowledgement (Continuous tone) Horn is acknowledged manually by button or functional input. Automatic acknowledgement (Pulsed tone) Horn is acknowledged automatically according to the set time. Horn priority acknowledgement A message can only be acknowledged, if the horn is acknowledged before. The setting horn priority acknowledgement contradicts to the setting horn locking, which can be single set for every input. For this case by choosing horn priority acknowledgement the setting horn lock of all message inputs is deactivated automatically 5.4 Buttons and functional inputs In this part of the dialog the functions of the annunciator listed below are assigned to the buttons T1...T4 as well as to the functional inputs 1 and 2. Multiple assignments are possible. Page 17 of 23 Within the parameterization software the assignment is done by a matrix. The lines correspond to the functions, the rows represent buttons or functional inputs. Realised links are check marked.
Function Meaning Acknowledgement Gr. 1 Acknowledgement of all messages of reporting sequence 1 Acknowledgement Gr. 2 Acknowledgement of all messages of reporting sequence 1 Reset Group 1 Reset of all messages of reporting sequence 1 (e.g. in case of 2-frequency-flashlight) Reset Group 2 Reset of all messages of reporting sequence 2 (e.g. in case of 2-frequency-flashlight) Acknowledgement horn Acknowledgement horn Lamp test Lamp test Function test Simulation to exitate all inputs Toggle relays Bistable relay, switching over with every exitation (Flip-flop-function) Wipe relays Relay switches by every excitation and drops off again after the wipe duration ( 4 ms... 1 s). Respectively only one of the two functions toggle relays oder wipe relays can be used alternatively. The selected relay function can again only be assigned to one button. Multiple assignments are here not possible! 5.5 Functional relays The functional relays R1... R4 can be free assigned to the functions given in the following table. Function Meaning Collective report 1 Collective report of the reporting sequence 1 Collective report 2 Collective report of the reporting sequence 2 Horn Horn triggering Toggle / Wipe Toggling or wiping of the relay output (acc. to the setting in the dialog Buttons and functional inputs ) Alive Live-contact of self-monitoring Button 1 4 Button controls relay output Functional input 1 / 2 Functional input controls relays output Within the parameterization software the assignment is done by a matrix. The lines correspond to the functions, the rows represent buttons or functional inputs. Realised links are check marked. Page 18 of 23
Multiple assignments, e.g. combiation of collective reports, are possible. The button line relays inversion defines for every relay either the use of the switching function or its negated execution. For example then the relay drops off on appearance of the collective report. 5.6 Data transmission With the two buttons read data from BSM and write data to BSM the parameterization can be read out from BSM or overwritten in the BSM device. Please be aware to set-up the used COM-port and the baud rate ( factory set 9600 Baud) of your personal computer before data transmission. State messages of the course of the data transmission are displayed in the data traffic window. With the two buttons save data record and open data record the parameterization file can be saved for later use or loaded from a existing file. 5.7 Labelling strips The texts for the description of the messages and buttons defined in the parameterization program can be printed automatically on labelling strips. This function has to be invoked by the button print labels. In the background a MS-Word form opens automatically, which can be printed. For using the labelling print MS-Word has to be installed on your personal computer. 6 Monitoring lights and operating elements 2 1 3 4 Page 19 of 23 1 Signalling lights 1... 8, Function is dependend from reporting procedure 2 Signalling lights 9... 16, Function is dependend from reporting procedure 3 Buttons 1... 4 4 Watchdog OK Goes out on trouble The representation of the BSM 16 is given here only as an example to the clarification of the principle. The number of reporting groups or the LED colours of the signalling lights can differ depending on configuration and size of the fault annunciator.
