Function Check Alarms
A Function Check alarm indicates that the device is temporary non-valid due to some activities, for
example maintenance, on the device.
There are five parameters associated with FD_CHECK_ALM, they are described below.
FD_CHECK_MAP
The FD_CHECK_MAP parameter contains a list of informative conditions that do not have a direct impact
on the primary functions of the device. Below is a list of the conditions:
1. Check function
FD_CHECK_MASK
The FD_CHECK_MASK parameter will mask any of the failed conditions listed in FD_CHECK_MAP. A bit
on means the condition is masked out from alarming and being broadcast to the host through the alarm
parameter.
FD_CHECK_PRI
FD_CHECK_PRI designates the alarming priority of the FD_CHECK_ALM, see “Alarm priority” on
page 78 . The default is 0 and the recommended values are 1 or 2.
FD_CHECK_ACTIVE
The FD_CHECK_ACTIVE parameter displays which of the conditions is active.
FD_CHECK_ALM
FD_CHECK_ALM is an alarm indicating that the device output is temporary invalid due to on-going work
on the device.

The FD_RECOMMEN_ACT and RECOMMENDED_ACTION parameters display text strings that will give a
recommended course of action to take based on which type and which specific event of the alerts that is
active (See
