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 TFXM system. If this is not
possible and additional cable is to be added to the transduc-
ers, utilize RG59 (75 Ohm) cable and splices. Ensure that
both cables are of equal length. If additional cable cannot be
added in the field, contact the Dynasonics factory to
coordinate an exchange for the proper cable length.
Transducer cables that are up to 990 feet [300 meters] are
available.
2. Mount the TFXM 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. Mounting: Refer to Figure 1.3 for enclosure and mounting
dimension details. Ensure that enough room is available to
allow for maintenance and conduit entrances. Secure the
enclosure to a flat surface with four appropriate fasteners.
4. Conduit holes. 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
water tight 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.
