PART 1 - TRANSMITTER INSTALLATION
After unpacking, it is recommended to save the shipping carton and
packing materials in case the instrument is stored or re-shipped.
Inspect the equipment and carton for damage. If there is evidence of
shipping damage, notify the carrier immediately.
The enclosure should be mounted in an area that is convenient for
servicing, calibration or for observation of the LCD readout.
1. Locate the transmitter within the length of transducer cable that
was supplied with the TFXL system. If this is not possible, it is
recommended that the cable be exchanged for one that is of
proper length. Both transducer cables must be of the same
length.
NOTE: The transducer cable carries low level, high frequency
signals. In general, it is not recommended to add additional cable to
the cable supplied with the DTTN, DTTH, DTTS or DTTC
transducers. If additional cable is required, contact the Dynasonics
factory to arrange an exchange for a transducer with the appropriate
length of cable. Cables to 990 feet (300 meters) are available. To
add cable length to a transducer, the cable must be the same type
as utilized on the transducer. Twinaxial cables can be lengthened
with like cable to a maximum overall length of 100 feet (30 meters).
Coaxial cables can be lengthened with RG59 75 Ohm cable and
BNC connectors to 990 feet (300 meters).
2. Mount the TFXL transmitter in a location that is:

Where little vibration exists.

Protected from falling corrosive fluids.

Within ambient temperature limits -40 to +185 ° F (-40 to +85 ° C)

Out of direct sunlight. Direct sunlight may increase temperatures
within the transmitter to above the maximum limit.
3. If the transmitter will be subjected to a wet environment, it is
recommended that the cover remain closed after configuration is
completed. The faceplate of the TFXL is watertight, but avoid
letting water collect on it. Conduit hubs should be used where
cables enter the enclosure. Holes not used for cable entry
should be sealed with plugs.
NOTE: Use NEMA 4 (IP65) rated fittings/plugs to maintain the
watertight integrity of the enclosure. Generally, the left conduit hole
(viewed from front) is used for line power, the center conduit holes
for transducer connections, and the right holes are utilized for I/O
wiring.
