WHB Series Shutdown Panels for Reliable Engine Protection

Key Features of the WHB Series Shutdown Panels

• Direct Engine Flywheel Mounting: The panel is designed to bolt directly onto the engine’s flywheel housing, ensuring a sturdy installation that can handle vibration and harsh field environments.
• Swichgage® Protection System: Each Swichgage combines a mechanical gauge with an integrated limit switch, offering real-time indication and automatic shutdown when readings fall outside safe operating levels.
• Built-In Safety Monitoring: Factory-configured protection includes monitoring for low oil pressure and high coolant or oil temperature, preventing costly engine failures.
• Expandable Instrumentation Options: The panel includes provisions for adding extra gauges such as pump discharge pressure, voltmeters, or hour meters—ideal for more advanced engine setups.
• Emergency Manual Shutdown: Equipped with a PB128S emergency stop button, operators can instantly shut down the engine in unsafe situations or maintenance routines.
• Reliable Magnetic Switch: The included 117PH magnetic switch provides dependable automatic shutdown activation, ensuring quick response during abnormal conditions.
• Compatible with Mechanical & Diesel Engines: The WHB Series integrates smoothly with Murphy fuel shut-off solenoids or rack pullers, supporting engines without built-in electronic shutdown systems.
• Durable and Field-Tested Build: Constructed for demanding irrigation and agricultural environments, the panel maintains performance under temperature fluctuations, dust, and continuous runtime.

Applications of the WHB Series Shutdown Panels

• Irrigation Engines: Ideal for agricultural fields where engines run for long hours and require dependable protection against low oil pressure or overheating.
• Diesel Pumping Units: Used in pumping water, slurry, or chemical fluids where stable engine operation is critical for continuous output.
• Industrial Engine Installations: Perfect for remote or unmanned engine setups in manufacturing, process plants, and utility systems where automated shutdown is required for safety.
• Standalone Power & Generator Systems: Supports engines powering generators or auxiliary systems, ensuring that protection mechanisms are in place even when operators are not present.
• Oil & Gas Support Engines: Suitable for engines used on rigs, pumps, and remote industrial sites where reliability and protection are mandatory due to safety standards.

How the WHB Series Shutdown Panels Works

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.

WHB Series Shutdown Panels – Frequently Asked Questions

What does the WHB Series Shutdown Panel protect the engine from?
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.
Can I add more gauges or accessories to the panel?
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.
Is this panel suitable for diesel engines without an internal shutdown system?
Absolutely. It works with Murphy solenoid fuel shut-off valves or rack pullers, enabling full shutdown functionality even for mechanical diesel engines.
Is the WHB Series recommended for outdoor irrigation engines?
Yes. The WHB Series is widely used in High Plains and agricultural irrigation applications due to its durability and reliable monitoring capabilities.
Can the shutdown limits be adjusted?
Yes. Both the oil pressure and temperature Swichgages have adjustable shutdown setpoints, allowing operators to fine-tune protection based on their specific engine requirements..
What type of installation does the panel support?
The WHB Series mounts directly to the engine flywheel housing, ensuring stable, vibration-resistant installation suitable for continuous use in rugged environments.
