What to do if Event counter 1 Number underruns above threshold Process value alarm on Siemens SITRANS P320?
- B
  Brianna KingSep 9, 2025
  The 'Event counter 1 Number underruns above threshold Process value alarm' on your Siemens Transmitter means that the number of times the process value has fallen below the limit (defined in 'Lower limit' and 'Monitored value' parameters) has reached the set threshold. The solution is to reset and acknowledge the event counter, examine the process conditions, and review the limit monitoring and event counter settings.

What to do if Event counter 1 Number underruns above threshold Maintenance alarm on Siemens SITRANS P320 Transmitter?
- N
  nrichardsonSep 8, 2025
  The 'Event counter 1 Number underruns above threshold Maintenance alarm' on your Siemens Transmitter indicates that the number of underruns of the process value, as defined by the 'Lower limit' and 'Monitored value' parameters, has exceeded its threshold. To fix this, reset and acknowledge the event counter, then check the process conditions and the limit monitoring and event counter settings.

What to do if Event counter 2 Number overruns above threshold Maintenance required on Siemens SITRANS P320?
- L
  Lisa TuckerSep 7, 2025
  If your Siemens Transmitter shows 'Event counter 2 Number overruns above threshold Maintenance required', it signifies that the process value has exceeded its defined limits ('Upper limit' and 'Monitored value') frequently enough to reach the threshold. You should reset and acknowledge the event counter, check the process conditions, and verify the settings for limit monitoring and the event counter.

What to do if the Siemens SITRANS P320 Transmitter is out of specification?
- T
  Tony FloydAug 22, 2025
  If the Siemens Transmitter detects deviations from permissible ambient or process conditions, it indicates that the measured value is unreliable, or deviations from the set value in the actuators are likely greater than anticipated. To resolve this, check the ambient temperature or process conditions. If possible, install the device at a different location.

What to do if Event counter 1 Number overruns above threshold Maintenance alarm on Siemens SITRANS P320?
- F
  Frank WebbSep 5, 2025
  The 'Event counter 1 Number overruns above threshold Maintenance alarm' on your Siemens Transmitter indicates that the number of overruns of the process value, which is set in the 'Upper limit' and 'Monitored value' parameters, has reached the specified threshold. To resolve this, reset and acknowledge the event counter, then check the process conditions and verify the limit monitoring and event counter settings.
