11.3Micro Motion customer service
To speak to a customer service representative, contact the Micro Motion customer service department. Contact information is provided in Section 1.10.
Before contacting Micro Motion customer service, review the troubleshooting information and procedures in this chapter, and have the results available for discussion with the technician.
11.4Transmitter does not operate
If the transmitter is not receiving power, all three LEDs on the user interface will be off.
1.Check the DeviceNet connector (see Section 11.7.1).
2.Ensure that the network is providing sufficient power to the device.
If at least one LED is lit, perform all of the procedures in Section 11.7.
If the procedures do not indicate a problem with the electrical connections, contact the Micro Motion customer service department.
11.5Transmitter does not communicate
If the transmitter does not appear to be communicating, the wiring may be faulty or the communications device may be incompatible. Check the wiring and the communication device. See Chapter 4 for ProLink II and Pocket ProLink, or Chapter 5 for a DeviceNet tool.
If you are trying to communicate via the IrDA port, ensure that the port is enabled, that
