Warrick 26B1D0P Control
The Warrick 26B1D0P is a high-performance conductivity liquid level control engineered specifically for boiler low water cutoff (LWCO) applications. This 120Vac supply voltage relay operates with a 10,000-ohm sensitivity, making it ideal for standard water-based systems where precise resistive sensing is required. As an open board liquid level control, it is designed for space-efficient integration, utilizing a retrofit standoff style and an included retrofit plate for seamless installation into existing control panels. The unit features spade terminals for secure electrical connections and a standard SPDT relay configuration (1 NO / 1 NC), allowing for versatile signaling or load control of burners and pumps.
Field reliability is enhanced by a built-in 3 second time delay, which filters out nuisance trips caused by turbulence or surging within the boiler. This specific model, Warrick PN 26B1D0P, includes a critical manual reset with power outage feature. In the event of a low water condition, the remote mount normally closed pushbutton must be depressed to restore operation once the level is corrected. The power outage logic ensures the LWCO control board ignores brief power fluctuations, preventing unnecessary lockdowns after a facility-wide power loss while maintaining strict CSD-1 compliance for safety interlocks.
- Broad Compatibility: The retrofit standoff style and spade terminals allow for fast replacement of legacy 16 and 26 series controls.
- Reduced Nuisance Trips: Integrated 3-second delay ignores liquid surging, ensuring stable boiler low water cutoff operation.
- Enhanced Safety: The manual reset function ensures a technician inspects the system before resuming boiler firing after a trip.
- Logic Persistence: The power outage feature prevents the system from locking out during momentary voltage drops, reducing service calls.
- Field Serviceable: The remote mount NC pushbutton provides flexible installation options for external reset stations.
How do I test the Warrick 26B1D0P without draining the boiler?
The manual reset button doubles as a test feature. Holding the pushbutton for 3 seconds simulates a dry probe condition, allowing you to verify the LLCO circuit trip without manually lowering the water level.
What is the purpose of the 10,000 ohm sensitivity rating?
The 10K ohm sensitivity is calibrated for standard tap and boiler water. It provides enough resistance to detect liquid presence while remaining high enough to ignore heavy steam or light foam that could cause false "wet" signals on higher sensitivity boards.
Can this control be used for pump-up or pump-down applications?
The 26B1D0P is a direct acting control typically used for safety limits. For differential level control (pump-up/down), a Series 16 or 16M with dual-probe logic is generally recommended unless using the SPDT contacts for a single-point high/low alarm.
