3. Constuction
Control unit for a single-phase submersible pump.
Functions are controlled from the PFC-M
electronic control panel, which reads the power
factor (PF) for protection against dry functions,
without installing the level probe in the well.
The PFC-M control panel enables setting:
- The motor rated power
- The PF alarm limit
- The minimum and maximum limits for power
voltage
- Programming 4 restarts for the pump when there
is no water
- The pump working times and the stops if there is
no air in the tank (patented system).
Materials
- Thermoplastic case
- Electronic card, containing:
• Auxiliary circuit fuse
• Transformer
• Starting relay
• PFC-M electronic control panel with display
and microprocessor
• Terminals for connecting the power line
• Terminals for connecting the motor
• Terminals for connecting pressure switch or
float switch
• Terminals for connecting the RA 100 remote
alarm panel or MSP clean signal panel
• Cables for capacitor connection
- Capacitor
- Cable glands
