Table: MaintAlerts condition text
Condition Text in MaintAlerts	Meaning	Action
Calibration Data Questionable	One or more calibration values outside of valid range or no manufacturing calibration data is present.	Logic solver card should be returned to Emerson.
Modules Not Executing at Configured Scan Rate	The logic solver has set the actual scan rate longer than the configured scan rate based on the estimate of execution time at download.	Change the logic solver scan rate to match ACT_SCAN_TIME diagnostic parameter value. Re-download.
Non-Volatile Memory Battery or Chip Failure	NVM battery or chip failure has been detected during periodic test, or not able to restore saved parameter records after powerup or reset, or a CRC error occurred when writing a parameter record.	Check the value of DIAG_STATUS and CONTROL_STATUS. If the condition is in DIAG_STATUS, the logic solver card should be returned to Emerson. If the condition is in CONTROL_STATUS and the card is in an unconfigured state after powerup, download the logic solver.
Channel Error	OINTEG is Bad on one or more channels.	Check the values of channel STATUS parameters for more information. Problem can be in the card or in the field.
SISNet Error	Any condition other than High Error Rate is active in P2P_STATUS.	Check value of P2P_STATUS. Transmit errors indicate a problem with this card. Receive and Synchronization errors may be associated with another card. Contact technical support if the condition is persistent or repeats.
Partner Not Available	Partner card is not responding to heartbeat messages or is responding but is not configured.	This condition can be due to a temporary situation such as a proof test being underway. If the condition persists longer than two minutes, the partner may have a fatal error. Check the value of PAST_ERROR on the partner card. This condition is active if the Partner Not Present condition is active.
Partner Not Present	Partner card is not responding to heartbeat messages.	This condition is due to the partner card not being in the slot, in the slot but in a failed or unpowered state, in the process of powerup testing, or having a problem with the redundancy link.
Card Not Communicating	One card of a redundant pair is not communicating with the controller. Not applicable to a simplex logic solver.	Condition can be expected if one card is in a failed or unpowered state, or is having a problem communicating with the controller. If the latter occurs on an Active logic solver, an uncommanded switchover will occur and will be indicated in PAST_ERROR.
Card Not Fully Operational	The same PAST_ERROR condition was present on back-to-back resets.	Check the value of PAST_ERROR and refer to the action for it.
