About the KRB 202
The KRB 202 is a complete engine safety unit with a built-in hour meter. A bright four-digit display shows engine RPM or running hours at the press of a button, and ten indication lamps show the full health of the engine on one panel: Supply On, Battery Reversed, Fuse Open, Charge, Stop Solenoid On, Low LOP, High Temp, Aux Trip, Emergency Stop and Overspeed Trip.
It monitors four fault inputs, indicates a blown fuse and has a built-in charge lamp. Push buttons on the back of the unit are used for setting it up on site.
It protects against wiring mistakes too: it indicates reverse battery connection and has a reverse battery protection relay for the charging alternator. The LOP bypass timer allows oil pressure to build during starting, a 70 Amp contact drives the stop solenoid directly, and a stop timer suits ES (Energised to Stop) type solenoids. It works on 8 to 30 V DC and measures 144 × 100 × 72 mm.

What the technical words mean
- LOP / LLOP
- Low (Lube) Oil Pressure. If oil pressure falls too low, the engine is shut down before its bearings are damaged.
- LOP bypass timer
- Oil pressure is low for a few seconds while an engine starts. This timer ignores low oil pressure during that time so the engine is not stopped by mistake.
- ES solenoid
- Energised to Stop. A fuel solenoid that must be powered to stop the engine. The stop timer keeps it powered long enough for the engine to come to rest.
- Charge lamp
- A lamp that shows whether the engine’s battery charging alternator is working.
- Fuse fail indication
- Warns when the fuse protecting the safety circuit has blown, so the engine is never left running without protection.
- Over speed / under speed
- Protection that acts when the engine runs faster or slower than its safe speed range.
- Aux trip
- A spare fault input that can be wired to any extra protection the engine needs, so the unit can stop the engine for it too.
- Reverse battery protection
- Protects the electronics if the battery is connected the wrong way round.
