DIESEL ENGINE PROTECTION MODULE

The BE172 engine protection module 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 Auxiliary alarm. It provides a MANUAL mode of operation via a 30A Key- switch.

The display indicates battery voltage & h-counter. You can adjust, on-site, PRE-GLOW timing, several timing options for STOP SOLENOID,  Fuel Alarm Shut-Down options, Auxiliary Alarm Options, and other miscellaneous functions. The tropicalized electronic boards are hosted in a rustproof rugged steel box. A gasket made of a special polymer protects 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 feature a high degree of mechanical safety in case of shock and vibrations.

WHAT IS BE172 SUITABLE FOR?

USE BE172 ENGINE PROTECTION MODULE ANYTIME YOU NEED A LOCAL START-STOP FOR DIESEL ENGINES AND RELIABLE SAFEGUARDS TO PROTECT THE MACHINERY. THE BE172 IS THE IDEAL SOLUTION WHEN YOU RETROFIT ANY DIESEL-DRIVEN MACHINERY FOR PRIVATE OR COMMERCIAL / INDUSTRIAL USE.

ALARM MONITORING

THE FOLLOWING PICTURES SHOW HOW THE DISPLAY REACTS IN CASE OF ALARMS. IN THE CASE OF PRE-ALARM THE MESSAGES BLINK ON AND OFF. ONCE THE ENGINE STOPS THE FIRST 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 'ROTATES' THE MESSAGES ACCORDINGLY. THE DISPLAY ALLOWS SPECIAL TEXT INDICATIONS FOR TAILOR-MADE APPLICATIONS

TYPICAL WIRING DIAGRAM

BE172 INSTRUCTION MANUAL

The BE172 engine protection module 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 output 'FUEL' drives a relay suitable for an 'ENERGIZED to RUN' solenoid. This output energizes all the time you need to run the engine. This output automatically shuts down when you stop the engine or an alarm occurs. If you need an 'ENERGIZED to STOP' output, you can program timing for the parameter [P2].

ENGINE PROTECTION WIRING DIAGRAM

This way, the output 'ALR' will no longer work as 'ALARM OUTPUT', but as 'STOP SOLENOID'. In other words, when you use the BE172 in ENERGIZED TO STOP mode, you can not benefit from the ALARM output.

We recommend using relays to drive all outputs. The BE172 features short circuit proof outputs [6] capable to supply 200mA in normal conditions. You can use a 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 flywheel diodes to suppress the electric noise of the relays.

The KEY-SWITCH [4] is capable of directly driving the starter motor via the terminal [50]. You must connect the terminal [30] of the KEY-SWITCH [4] to the battery plus.

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 the battery minus the 'PRG' blade terminal during the power supply connection. Before connecting the supply you have to choose one of the adjustable parameters [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.

PROGRAMMING  MANUAL

If you correctly followed the procedure, The Be172 will display the message [proG] and will display the available options as described in the programming manual. Once you successfully programmed a parameter, you have to remove the supply. All the time you connect the dc supply, the Be172 shows on the display the settings different from the factory settings.

WHAT IS AN ENGINE PROTECTION MODULE?

The Bernini Design Be172 operates reliably in a range of environments, from minus 30 up to 70 degrees Celsius. In some situations, LCD displays (Liquid Crystal displays) are not recommended at the extremes of this range. As a matter of fact, it is quite difficult to obtain good readings below 5 degrees Celsius on an LCD Display. To avoid problems at low temperatures, the BE172 features a -40/+85 degrees Celsius rated solid-state, LED display.

The majority of the applications for an Engine Protection Module find a convenient mounting place directly on the frame of a Diesel Generator. In this case, the Be172 Engine Protection Module is both rugged and vibration-proof.
