9. For flow meters that provide a
frequency output, measure and
record output(s). Compare calculated
vs. displayed flow rates.
(F-1200 or FB-1200 only).Confirm both
turbines produce pulses
The average frequency output signal is a 0-15 VDC pulsed output
ranging up to 200 Hz and must be measured with a frequency counter or
oscilloscope. Measure DC Frequency (Hz) at T4 from terminal 6(+) to 7(-).
GPM = Frequency in Hz X 60 X Meter Factor in ppg (refer to calibration tag
for meter factor)
For the F-1200 or FB-1200 Dual Turbine model, also measure and record
the top and bottom turbine signals.
Top Turbine: T4-12(+) to T4-2(-) Bottom Turbine: T4-13(+) to T4-2(-)
Also measure DC volts on same terminals. 5 to 7 VDC is normal for a
spinning turbine, 0 or 14+ VDC indicates a stopped turbine. (1 to 4 VDC
could indicate a problem.)
10. Compare and record the displayed val-
ues with those shown on the building
control system. Scroll through the D-100 menu pages and confirm that the rate and total
current values and engineering units shown agree with the information
shown on the building control system display. Record the results.
End of standard commissioning. Please contact ONICON if any questions arise.
COMMISSIONING WORKSHEET
Please read all installation instructions carefully prior to proceeding with these steps. Wiring
diagrams are located in this manual. Use the following worksheet for checking off the
commissioning steps and recording measured values.
