MAINT_ALARMS
A maintenance alarm indicates either the device or some part of the device needs maintenance. If the
condition is ignored, the device eventually fails.

MAINT_MAPPED parameter contains a list of conditions indicating either the device or
some part of the device needs maintenance soon. If the condition is ignored, the device
eventually fails. The following are the seven parameters mapped by default with
MAINT_MAPPED:

Field background load error
•
Surface Signal Strength Fault
•
Surface Signal Quality Fault
•
Interface Signal Strength Fault
•
Interface Signal Quality Fault
•
Sensor Param Write Failure
•
Background Not Set
•
Field Background not compatible
•
Un-reliable Sensor Communication

MAINT_MASK parameter masks any of the failed conditions listed in
MAINT_MAPPED. A bit on means that the condition is masked out from alarming and is
not reported.

MAINT_PRI designates the alarming priority of the MAINT_ALM. The default is 0.

MAINT_ACTIVE parameter displays the alarms that are active.

MAINT_ALM parameter indicates that the device needs maintenance. If the condition is
ignored, the device fails.

CHECK_ALARMS
It indicates that the output signal is temporarily invalid due to on-going work on the device.

CHECK_MAPPED parameter contains a list of informative conditions that do not have a
direct impact on the device's primary functions.

CHECK_MASK parameter masks any of the failed conditions listed in
CHECK_MAPPED. a bit on means the condition is masked out from alarming and is not
reported.

CHECK_PRI parameter designates the alarming priority of the CHECK_ALM. The
default is 0.

CHECK_ACTIVE parameter displays the check alarms that are active.

CHECK_ALM parameter indicates check alarms. These conditions do not have a direct
impact on the process or device integrity.

DEVICE_RESTART_REQUIRED parameter is used to ensure that all tuning parameter
modifications have been activated in the sensor board, a reset is required.
