Input Wiring<br />
Turbine <strong>Flow</strong>meter Input<br />
The Turbine Input 1 on the main circuit board provides the turbine flowmeter input signal generated<br />
by a magnetic pickup, enabling the <strong>Scanner</strong> <strong>2000</strong> to calculate and display instantaneous flow rates and<br />
accumulated totals. Wire as shown in Figure 3.4.<br />
Note If the expansion board option is installed, a second turbine input is available. See Figure A.17, page A-12,<br />
for Turbine Input 2 wiring instructions.<br />
