Carefully remove the contents of the shipping carton and
check each item against the packing list before destroying
any packing material. If there is any shortage or damage,
report it to the factory immediately.
Refer to Figures 2-1 and 2-2 for mounting dimensions of
the integral and remote instruments, respectively.
••••• The Series 505-1302 Series transmitter is designed for
field mounting, but it should be mounted in a location
free from vibration, corrosive atmospheres, and any
possibility of mechanical damage.
••••• For convenience at start-up, place the instrument in a
reasonably accessible location. Ambient temperature
should be between -40
o
F and 160
o
F (-40
o
C to 70
o
C).
••••• The 505-1302 Series transmitter is available with the
electronic unit and transducer as either a single inte-
gral assembly or separated by two coaxial cables in the
remote configuration.
••••• The transducer must be mounted vertically in either
configuration.
••••• Extended sensor lengths and special mountings can be
provided to fit specific mounting applications.
••••• When mounting the transducer, consideration must be
given to the 12-inch Near Zone. If the level rises to
within 12 inches of the sensor face, a 20 mA signal is
generated; the Near Zone LED lights; and the Near
Zone Alarm Output drops from 24 Vdc to 0 Vdc.
••••• The typical conical beam angle of the ultrasonic signal
is 10-12 degrees. Therefore, it is necessary to ensure
that a channel wall, ladder, or other obstruction is not
within this beam, and is not causing erroneous reflec-
tions that can affect the system operation.
••••• An optional mounting kit (285-1-176) is available for
both integral and remote mounted units. The
mounting stand is used to hold the unit in place
above the flowstream. The mounting kit moves
vertically and horizontally for maximum placement.
