3. Constuction
Control unit for a three-phase submersible pump.
Functions are controlled from the PFC-T
electronic control panel, which reads the power
factor (PF) for protection against dry functions,
without installing the level probe in the well.
The PFC-T control unit also detects the phase
failure and the sequence of phases in the power
line and 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
- Door lock master switch:
- Power line fuses
- Auxiliary circuit fuse
- Starting contactor
- Transformer
- PFC-T electronic control panel with display and
microprocessor
- Terminals for connecting the power line
- Terminals for connecting pressure switch or float
switch
- Terminals for connecting the RA 100 remote
alarm panel
- Cable glands
