Maintenance required alerts
A Maintenance required alert indicates that the device or some part of the device needs maintenance
soon. If the condition is ignored, the device will eventually fail. There are five parameters associated with
FD_MAINT_ALM, they are described below.
FD_MAINT_MAP
The FD_MAINT_MAP parameter contains a list of conditions indicating that the device or some part of
the device needs maintenance soon. The priority is not the same as the MAINT_PRI parameter described
below. It is hard coded within the device and is not user configurable.
Note that maintenance alarms are not enabled by default for the Rosemount 2240S.
Below is a list of the conditions:
1. Auxiliary Device Measurement Close to Limit
FD_MAINT_MASK
The FD_MAINT_MASK parameter will mask any of the failed conditions listed in FD_MAINT_MAP. A bit
on means that the condition is masked out from alarming and being broadcast to the host through the
alarm parameter.

The default is 0 and the recommended values are 3 to 7.
FD_MAINT_ACTIVE
