Engine Protection Module Be72
This page provides technical documentation for the legacy Be72 Engine Protection Module. For current projects, we recommend our latest Be172 controller, which offers enhanced features such as a digital display and advanced settings.
THE BE172 DIESEL ENGINE KEY START
The BE72 engine protection module includes the essential safeguards to protect a diesel engine. It features 7 LEDs, 3 Static Outputs, and a 30A Key Switch. It monitors an Oil Pressure-switch, Temperature-switch, Fuel Level-switch, Charger Alternator Voltage, and an Emergency-switch.
The BE72 provides a MANUAL operation via a 30A Key-switch. Adjustable settings include pre glow timing and stop solenoid timing. This fully coated controller is fitted on a rugged rust-proof metallic enclosure with a standard DIN72 cut-out.

The Be72 provides a Manual start for engine-driven applications. Automatic fault protections include Engine low oil pressure, High Temperature, Emergency, and Belt break. The Be72 provides the following outputs: Start, Stop, Preheat, Alarm, and Fuel solenoid. Be72 features a power switch (30A current) to energize the starter. All functions are indicated by means of 7 LED indicators.
INSTRUCTIONS
A) - Turn the [KEY-switch] clockwise to [PREHEAT] position until all LEDs illuminate.
B) - Wait until the only [OIL PRESSURE] and [CHARGER FAILURE] LEDs remain illuminated. If the [PREHEAT] timer is set, the yellow LED [PREHEAT] will illuminate according to the setting of the potentiometer (adjustable on the back from 10 up to 60 seconds).
C) - As soon as the green [ENGINE RUNNING] LED starts blinking, turn the key switch clockwise up to the spring-loaded momentary position. Hold this position until the engine starts. The [ENGINE RUNNING] LED will blink for a period of about 15 seconds. If the engine does not start within this period, the [STARTING FAILURE ALARM] will take place.
D) - To stop the engine, turn the key switch fully counterclockwise (Off position).
Rear View Connections Overview
In order to stop the engine, we recommend that you use an "energized to run" solenoid. It must be cpnnected to output #9 via a pilot relay. If you use an " "energized to stop" solenoid, turn the potentiometer on the back fully clockwise and connect the STOP SOLENOID relay to the output #8 via a pilot (driver) relay. The BE72 can provide up to 60-second stop cycle for the output #8. When you use output #8 to drive a STOP SOLENOID, the ALARM function output will no be longer available.
