IMPORTANT
DO NOT attempt to plumb or tighten the sensors while wires
are attached, as you risk pulling wires from cable attachments.
8. Wire sensors A & B to the PWTB Transmitter terminals
labeled A & B respectively. See the table in point 6 if
wiring a pre-ordered cable length for color coordination.
For strain relief, tighten cable glands.

IMPORTANT
Cable shielding should be connected to the Shield
terminal at the PWTB transmitter and left
unconnected at the sensor element end.
9. Connect conduit fittings to the sensors and PWTB
transmitter. Use water-tight fittings if required by your
installation conditions.
10. Wire PWTB transmitter for voltage or current output as
shown (Remote zero wiring is optional):
Figure 5. Transmitter Output/Remote Zero Wiring
11. Select 20 mA, 5 V, or 10 V output using the OUTPUT
switch based on wiring configuration.

12. Configure output range and sensor PSIG using DIP
switches 1-7. DIP 1-3 set the sensor PSIG corresponding
to the PWTB ordered. DIP 4-7 are used to set the desired
output signal range. Both use the binary code system
outlined in the table.

13. Inspect the LCD for readings. The LCD toggles between
sensor A, sensor B, and PSID reading.
• A dash mark at the top left of the LCD indicates the
reading of sensor A.
• A dash mark at the bottom left of the LCD indicates
the reading of sensor B.
• PSID reading is displayed without any mark at the
left of the LCD.
14. O/R symbol will flash in the bottom center of the LCD if
the differential pressure reading is over range. Select a
larger PSID range to avoid clipping of readings if this
occurs.
