- Overloads and excess temperature with automatic reset
- Excess currents in pumps (overload protection)
- Abnormal voltages
- Lack of phase and thermal protection KK
- Dry operation
- Rapid restarts
- Inconsistency of floats and/or probes
- Blocking of the pumps
As inputs the NGPANEL accepts either floats, level probes or depth sensors. Particular care must be taken:
- Floats and level probes cannot be used at the same time.
- Level probes can only be used with clear, clean water.
- The maximum level and minimum level alarms can be generated by floats or by level probes, or, if the depth sensor is used, by thresholds of the value read by the sensor itself.
It is possible, to use the alarm inputs so that the pumps stop in the case of reaching the maximum level, or too high motor temperature. In the case of an alarm, the pumps stop, the buzzer sounds, the corresponding alarm outputs are activated.
For more information you can read the NgPanel instruction manual.
