Testing The Wires; Final Assembly; Mounting The Transmitter - Neptune TRICON E Installation And Maintenance Manual

Testing the Wires

After wiring the transmitter, double-check to ensure it is wired correctly.
1. Apply power to the TRICON transmitter and check the output signals as follows:
At No Flow – there should be no pulses out of the digital output terminal, and a 4mA
l
direct current should be present in the 4-20mA loop.
At ½ Flow – the pulse rate out of the digital output terminal should be ½ the maximum
l
pulse rate, and a 12mA direct current should be present in the 4-20mA loop.
At Maximum Flow – the pulse rate out of the digital output terminal should be equal to
l
the maximum pulse rate, and a 20mA direct current should be present in the 4-20mA
loop.

Final Assembly

After testing is complete, the transmitter is ready for the final steps of the assembly process.
1. Shut off all power to the TRICON.
2. Place a generous amount of Dow Corning #4 compound on all exposed wire and
terminals.
3. Fill the inside of the terminal cover with the moisture compound.
4. Slide the terminal cover in place over the terminal screws.
5. Fasten the terminal cover with the cover screw and tighten until snug.
Take care not to overtighten the cover screw when securing the terminal cover.
6. Snap the strain relief fitting over the cable and push it into place in the cable entry hole.
7. Wipe away any excess compound.

Mounting the Transmitter

After you assemble the transmitter, it is ready to be mounted. If you are installing a TRICON
transmitter on a meter that does not already have a register mounted on it, skip to step 4. If
the meter does have a register mounted, begin at step 1.
1. Position the small end of the punch on the center of the seal pin at the base of the
register.
2. Using the hammer, drive the punch through the center of the seal pin. The head of the
pin should shear off.
