|
A009 | Transmitter | Transmitter in | • Allow the flowmeter to warm up (approximately 30 |
| Initializing/Warming | mode | seconds). The error should disappear once the flowmeter |
| Up |
| is ready for normal operation. |
|
|
| • If alarm does not clear, make sure that the sensor is |
|
|
| completely full or completely empty. |
|
|
| • Check the sensor circuitry. See Section 11.20. |

|
|
|
|
A011 | Zero Too Low | See A10 | • Ensure that there is no flow through the sensor, then retry. |
|
|
| • Cycle power to the flowmeter, then retry. |
|
|
| • If appropriate, restore the factory zero to return the |
|
|
| flowmeter to operation. |
|
|
|
|
A012 | Zero Too High | See A10 | • Ensure that there is no flow through the sensor, then retry. |
|
|
| • Cycle power to the flowmeter, then retry. |
|
|
| • If appropriate, restore the factory zero to return the |
|
|
| flowmeter to operation. |
|
|
|
|
A013 | Zero Too Noisy | See A10 | • Remove or reduce sources of electromechanical noise, |
|
|
| then retry. Sources of noise include: |
|
|
| - Mechanical pumps |
|
|
| - Pipe stress at sensor |
|
|
| - Electrical interference |
|
|
| - Vibration effects from nearby machinery |
|
|
| • Cycle power to the flowmeter, then retry. |
|
|
| • If appropriate, restore the factory zero to return the |
|
|
| flowmeter to operation. |
|
|
|
|
A014 | Transmitter Failed | Many possible causes | • Cycle power to the flowmeter. |
|
|
| • The transmitter might need service. Contact Micro Motion. |
|
|

|
A016 | Line RTD | The value computed for | • Check the sensor RTD circuitry. See Section 11.20. |
| Temperature | the resistance of the Line | • Verify that process temperature is within range of sensor |
| RTD is outside limits | and transmitter. | |
|
|
| • If the problem persists, contact Micro Motion. See |
|
|
| Section 11.3. |
|
|
|
|
A017 | Meter RTD | The value computed for | • Check the sensor RTD circuitry. See Section 11.20. |
| Temperature | the resistance of the | • Verify that process temperature is within range of sensor |
| Meter/Case RTD is | and transmitter. | |
|
| outside limits | • Check the characterization. Specifically, verify the FCF |
|
|
| and K1 values. See Section 6.2. |
|
|
| • If the problem persists, contact Micro Motion. See |
|
|
| Section 11.3. |
