5.4 VERIFICATION
This section describes the communication test, communication error check, analog output verification,
and configuration verification. It also contains subsections that involve manipulation of the process
pressures applied to the transmitter.
5.4.1 Communication Test
This test verifies that the HART Communicator and transmitter(s) can communicate properly. From user
configuration documentation, obtain transmitter IDs, addresses, and tags.
1. Turn on the HART Communicator by pressing the I/O key.
• If the Communicator finds a transmitter on a Point-To-Point Network, the Online menu with the
transmitter’s type and tag name is displayed. Go to Section 5.4.2.
• If the Communicator displays: No device found at address 0. Poll?, go to either
step 2 or 3, depending upon the type of network installed.
2. POINT-TO-POINT NETWORK
Check the following: Communicator connections, all other loop connections, power to transmitter,
transmitter address (0), and transmitter model number. Repair as necessary and repeat step 1.
3. MULTI-DROP NETWORK
Press Yes (F1) to enter digital mode and search for devices with polling addresses of 1-15.
• If the Communicator finds a transmitter on a Multi-Drop Network, the Online menu with the
transmitter’s type and tag name is displayed. Each transmitter connected to the loop can be
interrogated in sequence. Go to the next Section.
• If the Communicator displays: No device found. Press OK, check all loop connections,
power to transmitters, transmitter addresses (1-15), transmitter model numbers, etc. Repair as
necessary and repeat step 1.
5.4.2 Transmitter Selftest
To test the transmitter’s electronics, perform the following:
1. Establish communication; the Online menu displays. In the Online menu, Press 3 Device Setup.
2. In sequence, press 2 Diagnostics/Service, 2 Simulation/Test, 2 Test and finally 1 Selftest.
3. The message Selftest OK will be shown when the transmitter passes its selftest. If it does not pass, an
error message will be shown.
• If the transmitter passes, go to Section 5.4.3.
• If an error message is displayed, troubleshoot as necessary. Refer to Section 7 Calibration and
Maintenance as needed.
