16.10.3 mAO below 4 mA
Cause
• Output not powered
• Open in wiring
• Bad output circuit
• Process condition below LRV
• LRV and URV are not set correctly
• Fault condition if Fault Action is set to Internal Zero or Downscale
• Bad mA receiving device
Recommended actions
1. Check your process conditions against the values reported by the device.
2. Verify the receiving device, and the wiring between the transmitter and the receiving device.
3. Check the settings of Upper Range Value and Lower Range Value.
4. Check the Fault Action settings.
5. Verify channel configuration for the affected mA Output.
16.10.4 Constant mAO
Cause
• Incorrect process variable assigned to the output
• Fault condition exists
• A loop test is in progress
• Zero calibration failure
• mA Output Direction not set correctly
Recommended actions
1. Verify the output variable assignments.
2. View and resolve any existing alert conditions.
3. Check the direction parameters.
4. Check to see if a loop test is in process (the output is fixed).
5. If related to a zero calibration failure, reboot or power-cycle the transmitter and retry the zeroing
procedure.
16.10.5 mAO consistently out of range
Cause
• Incorrect process variable or units assigned to output
• Fault condition if Fault Action is set to Upscale or Downscale
• LRV and URV are not set correctly
Recommended actions
1. Verify the output variable assignments.
