ADVANCED POWER ALC 9020 Water Level Controller\

Checklist Before Installation:
- ALC 9020 sensor is designed for DC voltage only, DO NOT use with AC voltage.
- The sensor may not work in all water qualities. Although it is rare, pure water will not conduct the very low voltage used for sensing.
विशेष विवरण
- Minimum Volts DC 11.5
- Maximum Volts DC 90
- मैक्स Amp लोड 20

Installing Your Controller
- Install the ALC 9020 water sensor under the array to better protect the sensor from the weather. When the unit is used with Advanced Power Inc. Kits, the ALC 9020 simply plugs in to the existing wire harness using weather-pack connectors. Mount ALC 9020 on lower bottom corner of the panel.
- ALC 9020 can be attached to your mounts by using the provided self-tapping screws.
- Simply route the water sensor wire to the tank and hang the sensor probes over top tank edge to the desired water height. (For protection & if possible, it’s better to route the sensor wires inside plastic conduit to the storage tank.)
- When extending the sensor wire use only direct burial, sunlight resistant 18-2 or smaller (18-24) gauge wire. API provides 20 feet of water sensor wire but extra sensor wire may be extended with purchase. ALC 9020 sensor has an automatic Start and stop feature, when tank water level rises and reaches the sensor ends for approximately 10 seconds consistently, the sensor will shut off power to the pump.
- The sensor will allow the pump to start again, when both sensor ends are not touching water for 10 seconds and water level recedes below them. Sensor ends may become corroded over time, simply clean or replace them.
Stainless probes may be shorted if needed. - The ALC 9020 will disconnect the load from the power supply (solar, batteries, etc.) when the power drops below 11.5 VDC. It automatically reconnects when the power reaches 12 volts.
- अधिकतम ऑपरेटिंग वॉल्यूमtage for this unit is 90 VDC, higher voltage 90VDC will cause damages.
Twenty-Five (25) AMP Inline fuse are recommended (but not required) in the power side, either positive or negative will work. There are no switches or settings inside the ALC 9020 to adjust, it is a preset/automatic device.

समस्या निवारण
If you experience issues while installing your product or trouble shooting, please contact our technicians so we can assist you.
- If the unit will not turn on or off correctly, check the connections. Lid can be removed and terminal connections checked. Check for corrosion at the end of the sensor wire. These connectors must be reasonably clean and free of corrosion.
- Check for damaged wires or connections.
