FIGURE 2-3 Analyzer Terminal Block Designations
3.1 Flow Sensor(s)
☞
☞
The analyzer can be used with up to four GLI impeller or
non-GLI flow sensors in any combination. Non-GLI sensors
must have a 0-2000 Hz. output such as provided by a pad-
dle wheel, turbine, vortex, and other flow sensors.
Wiring Tip!
Route each sensor cable in 1/2-inch,
grounded metal conduit to protect it from moisture,
electrical noise, and mechanical damage.
For installations where the distance between sensor and
analyzer exceeds the sensor cable length, indirectly
connect the sensor to the analyzer using a junction box
and interconnect cable.
NOTE:
Do not route the sensor cable in any conduit con-
taining AC or DC power wiring (“electrical noise”
may interfere with the sensor signal).
Refer to Figure 2-4 and connect the Sensor A cable (or in-
terconnect) wires to Terminals 10 and 11 on TB1, matching
polarity as indicated. Connect additional sensors to their
respectively-marked terminals.
