Flygt : MiniCAS II

A supervision relay for temperature and leakage sensors

The Flygt MiniCAS II is a compact, plug-in monitoring relay designed to protect small to medium submersible pumps and mixers from damage. It continuously monitors motor temperature and internal leakage, providing early warning of potential faults. In the event of overheating or seal failure, the unit automatically stops the pump or triggers an alarm, helping to prevent costly breakdowns and unplanned downtime.

Key Features

• The unit monitors motor thermal switches and leakage sensors to detect overheating and liquid ingress at an early stage.
• Early fault warning provides advance indication of developing faults, allowing maintenance to be planned before breakdown occurs.
• Communication between the pump and relay is achieved using only two wires with current sensing technology.
• Front-mounted LED indicators display power supply, temperature status and leakage alarms for quick diagnostics.
• The relay output automatically stops the pump or activates an external alarm when a fault is detected.
• Flexible monitoring capability: The device combines thermal protection with one leakage sensor as standard and can monitor up to two leakage sensors.
• Quick and easy installation - the compact unit plugs directly into a standard 11-pin socket.
