Wiring drawing
| Terminal | Meaning |
|---|---|
| N | Neutral (single-phase supply) |
| P | Phase (single-phase supply) |
| L | Load, to the motor |
| Overhead Tank C, BS | Tank low sensor |
| Overhead Tank C, TS | Tank high sensor |
| Underground Sump C, BS | Lower sump sensor |
| Underground Sump C, TS | Upper sump sensor |
- The controller and its printed manual label the sensor terminals BS (bottom sensor) and TS (top sensor). The low sensor goes to BS and the high sensor to TS.
- Each sensor has two wires, one to C and one to BS or TS.
- The motor connects between L and neutral. Connect the controller in parallel with the motor switch or starter, so the motor can also be run by hand.
- Sensors connect only to the controller. Never connect them to the 240V AC mains.
- For one single-phase (1Φ) motor up to 1 HP only. Not for motors with a DOL starter or 3-phase motors.
