2.3 Datalogger Connection

Following sensor and installation, connections between a Datalogger and Multiplexer(s) can be
made using the model 8032-5 interconnect cable. Each Multiplexer employed is connected to
the appropriate weather tight 10-pin Bendix connector mounted on the enclosure. Each
connector on a standard Datalogger is pre-wired to control and read the external Multiplexers.

3. MAINTENANCE

Maintenance for the Model 8032 Multiplexer/Terminal Board is minimal. The following
checks should be performed periodically though;
 Is there water or other contaminants intruding into the enclosure? At times water can
wick through the sensor cables onto the terminal board. This will at some point cause
problems with the system. Water or other contaminants can also enter through
improper use of the cable entries. Additional sealing of the entries can be done with
various sealing compounds such as RTV. If moisture is condensing inside desiccant
can be used to keep this to a minimum. Desiccant is available from the factory.
 Are connections corroding? If the unit is installed near salt water for example, salts
may form on the terminals inside the enclosure and cause malfunctions. In this event
check that the enclosure is properly sealed. Use sealing compounds if necessary.
Desiccant may also help prevent this buildup. Sealing sprays such as HumiSeal may
also help protect the connections.
 Is the earth ground connection acceptable? Check that corrosion has not built up
around the connection to the enclosure (outside or in). Disassemble, sand the
connection location to remove rust or corrosion, and reattach if necessary.
