INSTALLATION
2.1
PRELIMINARY TESTS
Prior to installation, check the sensors for proper operation. Complete the
following steps:
1.
Place the sensors in the correct order by referring to the labels on the
sensors and the provided paperwork.
2.
Starting with the first sensor, connect the sensors by plugging the male
connector from the second sensor into the female connector from the first
sensor. Proceed in this manner until the full string is connected.

Cable Connection Detail
Caution!
When connecting the sensors, make sure to line up the
orientation dot on the outside of the male connector with the two
orientation dots on the outside of the female connector. This will ensure the
pins and receptacles on the interior of the connectors align correctly. Push
the connectors together until they are completely mated.

Connected Cables
3.
Connect the completed string to a Model 8020-38 converter, PC, or
datalogger (refer to Section 2.6).
4.
Hold the first sensor in a vertical position and observe the reading. The tilt
sensor must be held steady while taking the reading. The observed reading
should be close to the factory vertical reading. Tilting the sensor in a
positive direction (A+ or B+, as marked on the sensor) should yield
increasing readings. Tilting the sensor in a negative direction (A- or B-)
should yield decreasing readings. The temperature indicated on the readout
should be close to ambient. Repeat this process with the remaining sensors.
5.
Once the preliminary tests are complete, disconnect the string from the
readout device and disconnect the sensors from each other.
Should any of these preliminary tests fail, see Section 5 for
troubleshooting.
2.2
SAFETY CABLE
GEOKON
strongly recommends attaching a safety cable to the bottom-most
(terminal) sensor, Model 6180T. This can be used to retrieve the assembly in the
event of an accident, and it also can be helpful when lowering the assembly into
the casing.
Model 6180-6 safety cable assemblies purchased from
GEOKON
consist of a
customer-specified length of aircraft cable (07-125SS316-E/M) with eye bolt and
hex nuts pre-attached for ease of installation, along with all hardware required to
anchor the string.
