2.0 INSTALLATION
2.1 Unpacking
Carefully unpack all of the components of the instrument and inspect them for any
damage that may have occurred during shipment. In the event of damage, refer to
page i of this manual for instruction.
For equipment shipped as a complete set with the sensor installed into the solar
radiation shield, inspect the wiring to ensure none of the wires have been pulled from
the sensor. Remove any packing materials that may have become lodged in the
sensor’s plastic shield.
2.2 Sensor
The sensor assembly is calibrated at the factory and is ready for immediate use. Power
can be applied to the sensor and measurements can be made immediately.
Make any necessary wiring connections to monitoring or recording instruments before
applying power.
If it has been set up as a separate item, remove the sensor from its shipping carton and
install the sensor into the solar radiation shield. The sensing element is located at the
end of the probe with the smaller diameter and it is covered by a protective membrane.
Place the sensing end of the probe into the shield first and slide it into the shield as far
as possible but one inch away from the top edge. A cable clamp is used to secure the
sensor and its cable to the shield housing.
2.3 Wiring
The electrical connections of the 110-WS-16TH sensor are presented below. The
standard wire colors presented refer to the wire supplied with the sensor whenever the
sensor is ordered by itself. The NovaLynx output wire colors refer to the extension cable
added by NovaLynx. Refer to the system wiring diagram for exact connections.
