The WHB Series Shutdown Panel continuously monitors key engine parameters—primarily oil pressure and coolant or oil temperature—using Swichgage® instruments. These gauges combine real-time indication with built-in limit switches that trigger automatic shutdown when readings move outside safe operating levels.
During operation, the magnetic switch receives input from the Swichgages. If low oil pressure or excessive temperature is detected, the switch activates the shutdown circuit, stopping the engine to prevent major mechanical damage. The PB128S emergency stop button provides an additional layer of operator safety, enabling immediate manual shutdown whenever necessary.
Optional accessories such as voltmeters, hour meters, and fuel shut-off solenoids integrate seamlessly with the panel, allowing tailored configurations for irrigation, pumping, or industrial engine applications.
The panel protects the engine from damage caused by low oil pressure and high coolant or oil temperature. When unsafe levels are detected, it triggers an automatic shutdown to prevent overheating or lubrication failure.
Yes. The WHB Series supports additional instruments such as voltmeters, hour meters, and pressure gauges. You can also add a fourth 2-inch gauge hole for further expansion.
Absolutely. It works with Murphy solenoid fuel shut-off valves or rack pullers, enabling full shutdown functionality even for mechanical diesel engines.
Yes. The WHB Series is widely used in High Plains and agricultural irrigation applications due to its durability and reliable monitoring capabilities.
Yes. Both the oil pressure and temperature Swichgages have adjustable shutdown setpoints, allowing operators to fine-tune protection based on their specific engine requirements.
The WHB Series mounts directly to the engine flywheel housing, ensuring stable, vibration-resistant installation suitable for continuous use in rugged environments.
