What to do if block alarms will not work on Emerson Rosemount 8800D Measuring Instruments?
- D
  Daniel DawsonJul 27, 2025
  If the block alarms on your Emerson Measuring Instruments aren't working, it could be due to several reasons: 1. **Alerts Not Enabled:** The FEATURES_SEL setting might not have Alerts enabled. You'll need to enable the Alerts bit. 2. **Notification Level:** The LIM_NOTIFY setting may not be high enough. Ensure it is set equal to MAX_NOTIFY. 3. **Fault Propagation:** The STATUS_OPTS might have the Propagate Fault Forward bit set. Clear this bit to allow alarms to occur.

Why mode will not leave OOS on Emerson Measuring Instruments?
- J
  John RaymondAug 6, 2025
  If the mode on your Emerson Measuring Instruments won't leave OOS (Out of Service), there are a couple of potential causes: * **Target Mode Not Set:** Ensure that the target mode is set to something other than OOS. * **Memory Failure:** If there's a memory failure, BLOCK_ERR will show the lost NV Data or Lost Static Data bit set. Try restarting the device by setting RESTART to processor. If the block error persists, it is recommended to call the factory.

How to fix communication problems with Emerson Measuring Instruments using HART?
- J
  Jacob WilliamsAug 16, 2025
  To troubleshoot communication problems with your Emerson Measuring Instruments when using a HART-based communicator: * Ensure a minimum of 10.8 Vdc is present at the transmitter terminals. * Inspect the communications loop. * Verify the presence of a loop resistor (250 to 1000 ohms) and measure its value (R) along with the loop power supply voltage (V). Confirm that [V - (R x 0.024)] > 10.8 Vdc. * Check if the transmitter is in multidrop or burst mode. * If you have a three-wire pulse installation, remove the pulse connection. * If the issue persists, consider replacing the electronics.
