Vulcan Hart 00-854517-00001 Oven Limit BP Switch

Regularly inspect the Limit BP Switch for signs of wear or corrosion. Clean any dust or debris from terminals and ensure the mounting is secure to maintain consistent operation.

• Turn off power and depressurize the equipment.
• Removed the old limit switch if replacing.
• Mount the Limit BP Switch in the designated location, ensuring proper orientation.
• Connect electrical terminals according to the wiring diagram.
• Secure all fittings and check that the switch actuator moves freely.
• Restore power and pressure, then test operation for proper activation at the specified cut-out pressure.

Common issues include failure to trigger at the correct pressure due to worn or corroded contacts, mechanical sticking of the actuator, or loose electrical connections.

The Limit BP Switch typically operates within a pressure range of 5–50 PSI and is rated for standard 120–240V circuits. Exceeding its maximum pressure rating may cause failure or inaccurate switching.
