DIESEL ENGINE PROTECTION MODULE

The BE172 includes the basic safeguards to protect a diesel engine. It features a 4-digit super bright white display, 3 static outputs, 7 digital inputs and a 30A-rated key switch. The BE172 monitors an Oil Pressure-switch, Temperature-switch, Fuel Level-switch, Charger Alternator Voltage, Emergency-switch and an Auxiliary alarm. The BE72 provides a MANUAL mode of operation via a 30A Key- switch. The display provides battery voltage & h-counter. You can adjust, on site, PRE-GLOW timing, several timing options for STOP SOLENOID,  Fuel Alarm Shut-Down options, Auxiliary Alram Options and other miscellaneous functions. The tropicalized electronic boards are hosted into a rustproof rugged steel box. A gasket made of special polymer provides protection against the elements. You have to provide a standard cut-out through hole suitable for DIN 72 panel instruments. Two fixing clips made of steel, features a high degree of mechanical safety in case of shock and vibrations.

BASIC ALARM INDICATIONS

THE FOLLOWING PICTURES SHOW HOW THE DISPLAY REACTS IN CASE OF ALARMS. IN CASE OF PRE-ALARM THE MESSAGES BLINK ON AND OFF. ONCE THE ENGINE STOPS THE FIRT CAUSE OF SHUTDOWN FREEZES THE MESSAGE ON THE DISPLAY UNTIL YOU TURN THE KEY TO OFF. IN CASE OF SIMULTANEOUS MULTIPLE ALARMS, THE DISPLAY FEATURES A BUFFER AND 'ROTATE' THE MESSAGES ACCORDINGLY. THE DISPLAY ALLOWS SPECIAL TEXT INDICATION FOR TAILOR MADE APPLICATIONS.

TYPICAL WIRING DIAGRAM

The BE172 connections are carried out via 0,8mmx6,3mm blade terminals. You are required to connect the inputs to switches [5]. The other side of the switches must be connected to battery minus, You can set up the controllers by connecting the PRG [7] terminal to battery minus. To drive Fuel or Stop solenoid you have to use external relays.

The suitable output for a ENERGIZED TO RUN mode is to use the output 'FUEL'. This output energizes all the time you need to start and normally run the engine. This output automatically shuts down when you stop the engine or automatically shuts down in case of dangerous alarms. If you need an ENERGIZED TO STOP output, you can program a timimng for the parameter [P2]. In this way the output 'ALR' will no longer work as ALARM OUTPUT, but as 'STOP SOLENOID'. The output 'FUEL' will continue to run in ENERGIZED TO RUN MODE. In other words whe you use the BE172 in ENERGIZED TO STOP mode, you can not benefit of the ALARM output.

We recommend to use relays to drive Alarm, Pre-glow and 'FUEL' outputs. The BE172 features short circuit proof outputs [6] capable to supply 200mA in normal conditions. You can use 12 or 24 V battery [2]. Use 12V or 24V relays according to the type of battery. The connection of the D+ [1] is not mandatory but recommended.  We recommend that you use flywell diodes to suppress electric noise of the relays.

The KEY-SWITCH [4] is capable of directly driving the starter motor via terminal [50]. You must connect the terminal [30] of the KEY-SWITCH [4] to the battery plus. We recommend that you connect a fuse of a suitable size to protect the wires in case of short circuit. In case you need an input with special funcstion we can make a special software to handle the AUX1 terminal (it stands for AUXILIARY INPUT 1).

HOW TO ADJUST THE BE172 SETTINGS

The standard software of Be172 features four basic parameters: [P1][P2][P3][P4]. You will enter the PROGRAM MODE when you hold to battery minus the 'PRG' blade terminal during the power supply connection. Before connecting the supply you have to choose one of the adjustable parameter [P1][P2][P3][P4] by grounding the terminal blade 'AUX1' for [P1](PRE-GLOW settings), terminal 'ALR' for [P2] (STOP SOLENOID settings), terminal 'FUEL' for [P3](FUEL settings) and terminal 'SPARE' for [P4](ALARM settings). You are allowed to choose only one parameter for a programming section. If you simultaneously connect to ground two inputs (e.g. 'AUX1' and 'SPARE') the BE172 will show the [err] message; you will not be able to proceed. If you correctly followed the procedure, The Be172 will display the message [proG] and will display the availbale options as described below. Turn on the key switch; the display will show in sequnce the available options. Turn OFF the key when you reach the desired option. The display will flash twice to indicate that BE172 stored the setting into the memory. Once you successfully programmaed a parameter, you have to remove the supply. Optionally you can program an other parameters or you will connect the all terminals after removing the 'PRG' connection.

P1 PRE-GLOW SETTINGS

TO ENTER THE [P1] SETTING USE 'PRG'+'AUX1'

You can set the PRE-GLOW time for the PRE-GLOW output. You are required to use a pilot relay. The output energizes when you turn the key to ON. During the PRE-GLOW time the display indicates the message [UUUU]. After the preset time-out,  the display will turn the message to [STA] indicating that you  are required to ignite the engine by acting on the KEY-SWITCH. When Be172 detects the ENGINE RUNNNING condition the Be172 immediately shuts down the PRE-GLOW output.

AVAILABLE OPTIONS ARE;

OFF (no pre-glow)  /  6"  /  15"  /  30"  / 45"  /  1' 

NOTE  " stands for second(s) and ' stands for minute(s)

P2 STOP SOLENOID SETTINGS

TO ENTER THE [P2] SETTING USE 'PRG'+'ALr'

Normally, you use a FUEL SOLENOID relay connected to the FUEL output. This is basically an 'ENERGIZED TO RUN' output. When you shut down the engine, the output disables the FUEL SOLENOID in order to stop the engine. In particular cases, especially when it is about marine engines, you are required to use a  STOP SOLENOID (so called 'ENERGIZED TO STOP' method). In this case you are required to use an output energized for a certain time in a way that BE172 stops the engine. It is necessary to energize the solenoid for a short time. This avoids to burn the STOP SOLENOID (it consumes some AMPS of current). Default setting for [P2] is OFF (as mention above FUEL SOLENOID MODE). This means that the output 'ALR' only works as ALARM output (you will connect a horn for example). When you program an opttion different from 'OFF' the Be172 automatically sets the 'ALR' output to work as 'STOP SOLENOID' output. In case of shut down or when you turn the key to OFF, the Be172 will energize the 'ALR' output in a way to energize the STOP SOLENOID PILOT RELAY. When you program a timing for the [P2] you only modify the logic of the ALARM output. The basic funcions of the FUEL SOLENOID output is not affected and works always.

AVAILABLE OPTIONS ARE;

OFF(only fuel solenoid is used) / 5" / 15" / 30" / 1' / 2'

NOTE  " stands for second(s) and ' stands for minute(s)

P3 FUEL SETTINGS

TO ENTER THE [P3] SETTING USE 'PRG'+'FUEL'

Default setting for [P3] is 'OFF'. This means a warning option in case of LOW FUEL ALARM. The engine will continue to run. The display will show the message [FUEL]. To cancel the alarm, you are required to stop the engine and fill the tank. If you set a time-out (or so called bypass timimg), the engine will automatically shut down after the by-pass time. To cancel the alarm, you are required to turn the key to OFF.

AVAILABLE OPTIONS ARE; OFF (no shut down) / 5'  /  10'  / 20' / 30' / 60' 

NOTE  ' stands for minute(s)

P4 ALARM1(SPARE) SETTINGS 

TO ENTER THE [P4] SETTING USE 'PRG'+'SPARE'

Default setting for [P4] is 'OFF'. This means a warning option without shutdown whe you cnnect to ground the terminal 'SPARE'. The display will indicate the message [ALr1]. The engine will continue to run. If you set a time-out (or so called bypass timimg), the engine will automatically shut down after the by-pass time. To cancel the alarm, you are required to turn the key to OFF and remove the cause of the alarm.

AVAILABLE OPTIONS ARE;

OFF (no shut down)  5" / 15" / 30" / 1' / 5' 

NOTE  " stands for second(s) and ' stands for minute(s)

WHAT IS ENGINE PROTECTION MODULE

 You may wish to know, what is an Engine Protection Module and what does it do?

Taken as a unit, it encompasses an intelligent electronic controller, of any form, that integrates a belt Alternator Monitoring Module and an Engine Control & Monitoring Module. Engine Protection Modules must provide clear visual indication by means of LEDs and Displays for all supervised parameters and alarms of the engine. The Protection Module will constantly monitor critical operating parameters and take steps to protect the engine from progressive damage. The Protection Module will shut down the engine unless the Engine Protection Shutdown feature has been disabled. When an out-of-range condition occurs,the Bernini Design Protection Module may determine to de-rate or even shut down the engine.

A chosen Bernini Design Engine Protection Module features a range of programmable settings (from a minimum of 30 to a maximum of 300) and is engineered to comply with  NFPA110 CAN/CSA-C282-M89 recommendations. Some of our genset controllers feature RS485 and CANBUS interfaces in order to communicate with engines equipped with ECUs  (Electronic Control Unit according to the SAE-1939 standard). Each user manual of a Bernini Design genset controller, illustrates the layout of the front panel of the controller. An Engine Protection Module should be capable of  interfacing with analogue sensors or switches for the OIL/°C/FUEL monitoring if the CAN BUS is not available and this is integrated by Bernini Design.

what is a diesel engine protection module

A Bernini Design Engine Protection Module operates reliably in a range of environments, from minus 30 up to 70 degree Celsius. In some situations LCD displays (Liquid Crystal Display) are not recommended at the extremes of this range. As a matter of fact it is quite difficult to obtain good readings below 15 degrees Celsius on an LCD Display. Ancillary functions of a Protection Module may include selected extra complex features like Generator Parallel and Synchronisation.

The majority of the applications for an Engine Protection Module finds a convenient mounting place directly on the frame of a Diesel Generator. In this case the Engine Protection Module must be both rugged and vibration proof (all Bernini Design Engine Protection Modules satisfy this requirement). In some case the Engine Protection Modules are connected with a separation as much as several hundred meters from the generator itself. This is not an issue of concern since that all Bernini Design generator control systems feature a rugged RS485 serial interface, allowing you to drive a twisted cable length as distant as 1000 metres.
