Solar Panel Specification and Installation

The power connectors P1 and P2 are identical in their input configurations. The Solar cell specification for continuous operations should be rated 6V @ 5 mA and the Solar cell input P1 includes a reverse polarity protection diode.

Tilt Sensor Connection

Sensor connectors T1 & T2 are used for connecting the tilt sensors to the signal conditioning unit are identical in their signal input specification.

Power Supply

All of the Keynes Controls tilt meter signal conditioning units required 6V for continuous operations. Under no circumstances should any input supply be greater than 9V as this would damage the unit.

The table below shows the sensor connections and colour code for tilt sensors supplied by Soil Instruments Ltd and Slope Inc USA.
