[031] Low Power; [033] Insufficient Pickoff Signal - Emerson Micro Motion 5700 Configuration And Use Manual

Configuration and Use Manual
MMI-20025166
Cause
The firmware or configuration loaded in the transmitter is incompatible with the board type.
Recommended actions
1. Ensure that the correct board is installed.
2. If this alarm occurred in conjunction with an effort to load a configuration into the transmitter, confirm
that the transmitter is of the same model as the one the configuration came from.
3. Reboot or power-cycle the transmitter to see if the alert clears.
4. If the alert persists, replace the transmitter.
5. If the problem persists, contact customer service.

17.13.18 [031] Low Power

Alert
Core Low Power
Cause
The enhanced core processor is not receiving sufficient power. This alert will not clear until you reboot or
powercycle the transmitter.
Recommended actions
1. Check the wiring between the sensor and the transmitter.
2. Measure the voltage at the core processor terminals and ensure that it is receiving a minimum of 11.5
volts at all times. If it is not, verify the power wiring to the transmitter.
3. Verify that the transmitter is receiving sufficient power.
a) If it is not, correct the problem and reboot or power-cycle the transmitter.
b) If it is, this suggests that the transmitter has an internal power issue. Replace the transmitter.

17.13.19 [033] Insufficient Pickoff Signal

Alert
Tube Not Full
Cause
The signal from the sensor pickoffs is insufficient for operation (enhanced core processor only).
Recommended actions
1. Check for two-phase flow.
2. Check the sensor tubes for plugging or coating.
3. Check for fluid separation by monitoring the density value and comparing the results against expected
density values.
4. Ensure that the sensor orientation is appropriate for your application. Settling from a two-phase or
three-phase fluid can cause this alert even if the flow tubes are full.
