Troubleshooting
11.3 Micro Motion customer service
To speak to a customer service representative, contact the Micro Motion Customer Service
Department. Contact information is provided in Section 1.8.
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.
11.4 Transmitter does not operate
If the transmitter does not operate at all (i.e., the transmitter is not receiving power, or the status LED
is not lit), perform all of the procedures in Section 11.14.
If the procedures do not indicate a problem with the electrical connections, contact Micro Motion
customer service.
11.5 Transmitter does not communicate
If you cannot establish communication with the transmitter:
• Check connections and observe port activity at the host (if possible).
• Verify communications parameters.
• If all parameters appear to be set correctly, try swapping the leads.
• Increase the response delay value (see Section 6.12.5). This parameter is useful if the
transmitter is communicating with a slower host.
11.6 Zero or calibration failure
If a zero or calibration procedure fails, the transmitter will send a status alarm indicating the cause of
failure. See Section 11.10 for specific remedies for status alarms indicating calibration failure.
11.7 Fault conditions
If the analog or digital outputs indicate a fault condition (by transmitting a fault indicator), determine
the exact nature of the fault by checking the status alarms with ProLink II software. Once you have
identified the status alarm(s) associated with the fault condition, refer to Section 11.10.
