Cleaver-Brooks Level Master Controller (Part No. 623-00193-000 / 623-0013-000, CT Version)

Product Overview

The Level Master Controller by Cleaver-Brooks—designated as Part No. 623-00193-000 or 623-0013-000, CT version—is a precision-designed level monitoring and control device for boiler feedwater systems. It delivers accurate detection of condensate and feedwater levels, protecting against nuisance shutdowns and optimizing boiler efficiency. The robust construction and modular design ensure stable performance in demanding industrial environments, guaranteeing extended service life and consistent control accuracy.

Technical Specifications

Installation Guide

1. Power Down: Shut off power to the boiler control panel before installation.
2. Panel Cutout: Prepare the panel with an appropriate rectangular cutout and de-burr edges.
3. Mounting: Gently insert the Level Master into the cutout and secure with the provided screws; ensure gasket forms a proper seal.
4. Electrical Connections:
   • Power: Wire neutral and line terminals to 110–240 VAC mains.
   • Probe Leads: Connect two probe wires to level sensor tips in the boiler; ensure proper polarity if marked.
   • Output Relay: Wire the SPDT relay contacts to the boiler control circuits (e.g., low-level shutdown or pump control).
5. Power Up & Initial Check: Restore power, and observe LED indicators—Power (should light), Level OK (green when water contacts probe), Alarm (red if level is out of range).

Maintenance Instructions

• Monthly Visual Inspection: Verify enclosure and gasket integrity, check for signs of moisture, corrosion, or loose screws.
• Probe Cleaning: Shut down boiler if required, remove scale buildup from probes using a soft brush or mild non-abrasive cleaner.
• Test Operation: Simulate water level change (e.g., lift probe or use test switch) and confirm the correct activation of the relay and LEDs.
• Electrical Check: Inspect wiring terminals and connectors for tightness and absence of oxidation.
• Periodic Calibration: Use adjustable sensitivity to accommodate changes in water conductivity (e.g., due to condensate purity or water treatment). Document changes.

Operational Tips & Safety Precautions

• De-energize Before Servicing: Always power down the unit before accessing internal components.
• Waterproof Seal: Ensure gasket remains in good condition and maintains NEMA 4/IP65 protection.
• Avoid Electrostatic Damage: While the unit’s front is protected, internal circuitry can be sensitive—minimize handling of exposed contacts.
• Proper Probe Placement: Ensure probe tips are mounted in representative water zones and do not contact metal surfaces that could cause false readings.
• Test Before Operation: After installation or maintenance, always test for proper level detection and relay actuation before returning to full boiler operation.
