Warrick 26B1A0A Level Control

The Warrick 26B1A0A is a robust conductive liquid level control designed for precise low water cutoff (LWCO) applications. Engineered for boiler water level control and pump management, this 120Vac module operates in a direct acting mode with 10,000 ohm sensitivity. The open board series 26 design features a 1/16" panel standoff style, making it ideal for integration into existing control panels where space is a premium. It utilizes a SPDT (1 NO/1 NC) relay coupled with spade terminal connections for reliable field wiring. To prevent nuisance tripping caused by turbulence or surging, the board includes a built-in 3 second time delay. This unit also incorporates a manual reset with power outage feature and a remote mount NC pushbutton interface, ensuring the system remains offline after a low-water event until manually cleared by a technician. The on-board test feature allows for rapid diagnostics of the liquid level control relay without disrupting the probe circuit.

Key Benefits

• Enhanced System Protection: The 3-second time delay prevents rapid cycling and equipment wear caused by boiling turbulence.
• Fail-Safe Operation: The manual reset feature ensures technicians can inspect the system before resuming operation after a low-water condition.
• Versatile Installation: The 1/16" standoff and compact open board design allow for seamless mounting in high-density HVACR control cabinets.
• Streamlined Testing: Integrated test feature and remote pushbutton compatibility simplify routine maintenance and ASME safety checks.

Common Questions

How do I wire the manual reset on the 26B1A0A?
The unit requires a normally closed (NC) pushbutton wired to the reset terminals. If power is lost or a low-water condition occurs, the relay latches open until the water level is restored and the button is manually depressed.

What is the maximum distance for the remote probe?
While the 10,000 ohm sensitivity allows for significant lead lengths, it is recommended to use shielded cable for runs exceeding 50 feet to eliminate electromagnetic interference (EMI) from high-voltage lines.

Can this board be used for sewage or wastewater?
The 10,000 ohm sensitivity is specifically tuned for potable water and steam boiler condensate. For high-resistance liquids like deionized water or extremely high-solids wastewater, a different sensitivity threshold may be required.
