Troubleshootioing

5.1 Identifying a Problem/Symptom

Use Table 5-1 as a guide to find and correct a problem when it occurs. Most problems are not

related to transmitter failure. It is important to be methodical when tracking down a problem.

If you experience a problem that you cannot solve using this guide, call the Drexelbrook 24-

hour Service 215-674-1234. You may also E-mail us: [email protected]. Further

service information may be found at our World Wide Web address www.drexelbrook.com.

When you contact us, be prepared to give the service person as much information as you

can about the model numbers, serial numbers, application requirements, and the materials

Section 5

5.2 Troubleshooting Connections

When troubleshooting the connections, verify the following items.

1. Loop devices are wired in series.

2. There is at least 250 ohms total loop resistance for HART communications.

3. There is at least 19 VDC available for the transmitter when a loop current of 20 mA is

flowing.

4. The open circuit voltage does not exceed 30 VDC

5. Power the unit from a portable source. 3 – 9 volt batteries in series will produce 27 VDC
