Control unit for pump stations with a maximal current consumption of 12A per pump at 230V or 400V (1- and 3-phase operation)
HIGHLIGHTS
- Alarm outputs (pot. free & 230VAC)
- Manual operation
- Operating hours counter
- Forced switching-on
- Durable LED display
- Small dimensions 210mm x 200mm x 110mm
- Add-on modules for a third digital input or module for mains failure detection and signaling (acoustic)
Why use the PumpGuard solo?
Input signal by
- Diver’s bell / pressure
- Pressure measurement with air-bubble introduction and blower monitoring
- Float switch (two digital inputs on board, third input on add-on module)
- Level probe / analogue input 4-20mA (0-400 mbar; add-on module)
Monitoring of
- Pump temperature sensor reversible (temperature guard)
- Pump temperature sensor irreversible (temperature limiter)
- Overcurrent
- Overfill (digital, pressure, analogue)
- Pump-time duration
- Minimal pressure at air bubble introduction
