If operating a CS125 indoors it is likely that there will be sources of
light and/or reflections that will create false readings and erratic
results.
If carrying out simple checks, blocking a lens or the sample volume
will simulate an INCREASE in visibility not a decrease.
7.1 Equipment grounding
The CS125 must be properly grounded by taking a ground wire with a minimum
cross sectional area of 6 mm
2 and maximum length of 5 m from the brass
grounding lug in the lower face of the electronics enclosure to an adequate
grounding point. The pole and foundations of a pole mounted installation will
provide some basic lightning protection and protection against radio frequency
interference and should also be correctly grounded.
7.2 Mounting the CS125
A pole mounting kit is supplied with the CS125. To mount the CS125 onto a pole:
1. Offer up the DSP plate to the pole and present the `V’ bolts from the other side
as shown.
2. Clamp the pole between the DSP plate and brackets by tightening using the
nuts and washers provided.
3. If a power supply enclosure has been supplied with the sensor it can be
mounted on the pole, near its base using the brackets supplied with the
enclosure. Alternatively the power supply can be mounted elsewhere, e.g. on a
wall at some distance from the sensor. The power supply enclosure should be
