Warrick DFB1A0K Control

The Warrick DFB1A0K is a rugged 120V conductivity control engineered for dual-function liquid level management in demanding industrial environments. Designed as a direct acting liquid level control, this unit excels in boiler low water cutoff protection and steam generator monitoring. With a 10K ohm sensitivity rating, it provides reliable solid state relay performance, ensuring precise electrode-to-liquid contact detection. This model features a critical manual reset function and a power outage reset capability, which prevents hazardous equipment dry-firing after a nuisance power loss. The 1/16-inch panel mount configuration and spade terminal connections facilitate a clean, professional install for technicians working on food service equipment or chemical delivery systems.

• Dual-Function Versatility: Manages independent level operations, making it ideal for simultaneous single-level and differential-level control.
• CSD1 Requirement Compliance: Meets strict safety standards for boiler installations requiring a manual reset following a low water condition.
• Electrolysis Mitigation: Utilizes AC current on the probe circuit to minimize mineral buildup and electrode degradation.
• Operational Stability: Integrated power outage feature ensures the system returns to its safe state only after liquid levels are confirmed and the reset is engaged.

Common Questions & Troubleshooting

Why is my control not sensing the liquid despite the probe being submerged?
Verify the solution's conductivity. The Warrick DFB1A0K is tuned for 10,000 ohm sensitivity. If you are dealing with high-purity condensate or specific glycol mixes, the resistance may exceed 10K ohms, necessitating a more sensitive controller. Also, check for "bridging" or mineral buildup on the probes.

How does the manual reset interact with power cycles?
Unlike standard relays, this unit is designed to hold the de-energized state during a low-water event. If power is lost and restored, the control remains in lockout until the liquid reaches the electrode and the manual reset button is depressed, ensuring a technician verifies the system.
