3.) The wiring nipple is attached to the instrument enclosure at the factory (see Photo
#1). The probe will normally have a coax electrical connector on top. Connect the
supplied short cable to the probe connector (the center conductor at the opposite
end of the cable is the “probe” wire). Thread the probe “pigtailed” cable end
through the wiring nipple (into the instrument housing) and tighten nipple onto the
top of the probe. DO NOT use the instrument enclosure for tightening.
4.) Connect the “probe” wire (center conductor of the coax) to the PROBE terminal
(see Photo #5) in the base of the instrument enclosure. The shield connects to the
ground terminal. Make sure the cable is under the cable stay.
5.) Install a conduit fitting to one of the conduit openings at the top of the instrument
enclosure. Use the supplied conduit plug for the other conduit opening. Follow all
applicable electrical codes when installing this conduit and wiring. It is strongly
recommended that you use a drip-loop to prevent water from entering the
instrument enclosure from the conduit.
6.) Using a twisted, shielded pair cable, connect the positive wire to the Loop (+)
terminal and the negative wire to the Loop (-) terminal. Tape over the shield - DO
NOT connect the shield and/or drain wire to the transmitter. At the power supply
end, connect the (+) to plus and (-) to minus, and also connect the shield and/or
drain wire to ground. Connect an earth ground-wire to the green screw inside the
Instrument Enclosure.
7.) Reinsert the puck into the instrument enclosure by visually lining the three tabs on
the puck with the corresponding guide slots in the base ring, and using firm
pressure, seat the puck. It can only fit in one orientation, DO NOT FORCE.
8.) Refer to Section B for calibration instructions.
Remote-mounted Transmitter Installation
1.) The probe will normally have a coax electrical connector on top. Connect the
supplied short coax cable to the probe connector (the center conductor at the
opposite end of the cable is the “probe” wire).
2.) Remove the cover of the interconnection housing.
3.) Thread the probe “pigtailed” cable end into the bottom of the interconnection
housing. Screw the interconnection housing onto the probe. Use the wrench flats
on the nipple and the body of the housing for tightening.
Before starting installation procedures in hazardous areas, ensure that
all power sources have been turned off and locked out. “Live” electrical
circuits can ignite flammable gasses and dusts.
Follow the wiring practices set forth in the National Electric Code, as well
as local electrical codes. These Codes supercede any information in this
manual.
Do not apply more than 33Vdc to the transmitter, as this may damage the
instrument.
