Troubleshooting

To return to normal operation:

1.Reconnect the 4-wire cable between the core processor and the transmitter (see Figure B-3or Figure B-4).

2.Replace the core processor lid.

Note: When reassembling the meter components, be sure to grease all O-rings.

11.25Checking sensor coils and RTD

Problems with sensor coils can cause several alarms, including sensor failure and a variety of out-of-range conditions. Testing the sensor coils involves testing the terminal pairs and testing for shorts to case.

11.25.1Remote core processor with remote transmitter installation

If you have a remote core processor with remote transmitter (see Figure B-1):

1.Power down the transmitter.

2.Remove the end-cap from the core processor housing.

3.At the core processor, unplug the terminal blocks from the terminal board.

4.Using a digital multimeter (DMM), check the pickoff coils listed in Table 11-13 by placing the DMM leads on the unplugged terminal blocks for each terminal pair. Record the values.
