ELECTRICAL INTERFERENCE

To minimise electromagnetic interference or 'noise', the sensor should be mounted away from

motors, generators and such like.

WIRING

Check the distance between the sensor and the measurement instrumentation. If necessary,

the sensor can be ordered with a longer cable attached.

Check the supply voltage is between 6 V DC and 28 V DC.

To use the 0-10 V output, the supply voltage must be at least 12 V DC.

IMPORTANT: Ensure the power supply is only connected to the PWR+ and PWR- wires, and the

polarity is correct, before switching the power on.

Do not switch the power off and on again quickly. If the power is switched off, allow 15

seconds before switching it back on.

All sensors come with a 1 metre cable and two mounting screws. The sensor can be mounted

on brackets or cut-outs of your own design, or you can use the fixed and adjustable mounting

bracket accessories which are shown below.

The supplied mounting screws are for use with a panel or bracket at least 2 mm thick. The

screws are 8 mm long.

Between the mounting holes, there must be a hole to allow the sensor a clear view through

the panel or bracket. This hole must be larger than the lens of the sensor or the aperture of

the air purge, if used. Use as large a hole as possible.

Note: The sensor must be grounded at only one point, either the cable shield or the mounting

screws, but not both.
