• Install the sensor in a 90° angle to the intended target surface. Make sure that no object
or reflection interferes with the 30° angle beam.
Figure 38 SR50A Beam Angle Clearance
Do not mount the sensor too far from the target surface. The further the
sensor is from the target, the more the absolute error increases. The maximum
measuring distance is 10 m (32 ft 10 in).
CAUTION!
Do not perform installation or maintenance procedures when there is a
risk of thunderstorm or lightning activity in the area.
WARNING!
A long cable between units (sensors, transmitters, power supplies, and
displays) can cause a lethal lightning-induced current surge. Always ground the
enclosure to a suitable grounded location with a short, low-resistance cable.
WARNING!
