How to troubleshoot no signal on Onicon F-1100?
To troubleshoot a 'no signal' issue with your Onicon Measuring Instruments, start by verifying that the meter is inserted correctly into the pipe and that the electronics enclosure is parallel with the pipe. Next, check the 24 V supply voltage and ensure correct wiring to the control system, referring to the wiring diagram. Finally, inspect the turbines for any debris.
What to do if analog signal is incorrect on Onicon F-1100?
If the analog signal on your Onicon Measuring Instruments seems high or low and does not correspond to the frequency output, check for a ground loop or offset voltage. Disconnect the analog signal input to the control system and measure the analog outputs directly from the flow meter. Re-connect the signal input to the control system and measure the analog signals again. Any difference between these readings indicates a potential ground loop or offset voltage.
Why is the reading too high on my Onicon Measuring Instruments?
If the reading on your Onicon Measuring Instruments is too high, it could be due to several factors. First, ensure there is adequate straight pipe run upstream of the meter. Verify the pipe size and contact the factory if it differs from the calibration tag. Also, check that the meter is inserted correctly into the pipe and that the electronics enclosure is parallel with the pipe. Confirm the wiring to the control system is correct and that output signals agree. Ensure the control system is programmed for the correct flow range or scale factor, and inspect the turbines for debris.
Why no flow rate on Onicon display module, but control system displays it?
If your control system displays the flow rate, but there is no flow rate indication on the local display module or BTU Meter for your Onicon Measuring Instruments, verify that all wires from the flow meter were connected to the display module or BTU meter. Specifically, ensure that the frequency output wire (green) is connected, as it is essential for any ONICON display or BTU meter to function correctly.
