Troubleshooting

11.14.4Checking for RF interference

If you are experiencing RF (radio frequency) interference on your discrete output, use one of the following solutions:

•Eliminate the RF source. Possible causes include a source of radio communications, or a large transformer, pump, motor, or anything else that can generate a strong electrical or electromagnetic field, in the vicinity of the transmitter.

•Move the transmitter.

•Use shielded cable for the discrete output.

-Terminate output cable shielding at the input device. If this is not possible, terminate the output shielding at the cable gland or conduit fitting.

-Do not terminate shield inside the wiring compartment.

-360° termination of shielding is not necessary.

11.15Checking ProLink II

Ensure that you are using the required version of ProLink II. ProLink II v2.3 or later is required for the Model 1500 transmitter with filling and dosing application. ProLink II v2.5 or later is required for meter verification, and for some of the features and functions described in this manual.

To check the version of ProLink II:

1.Start ProLink II.

2.Open the Help menu.

3.Click About ProLink.

11.16Checking the output wiring and receiving device

If you receive an inaccurate mA reading, there may be a problem with the output wiring or the receiving device.

•Check the output level at the transmitter.

•Check the wiring between the transmitter and the receiving device.

•Try a different receiving device.

11.17Checking slug flow

Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications. The presence of slugs can significantly affect the process density reading. Slug flow limits and duration can help the transmitter suppress extreme changes in reading.

Note: Default slug flow limits are 0.0 and 5.0 g/cm3. Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility of slug flow conditions.

If slug limits have been configured, and slug flow occurs:

•A slug flow alarm is generated.

•All outputs that are configured to represent flow rate hold their last “pre-slug flow” value for the configured slug flow duration.
