6.5.2.4 Alarm Settings

☛ Set the entities [High high alarm], [High alarm], [Low alarm], [Low low alarm],

and

[Alarm hysteresis] to the desired values.

For definitions, see FIGURE 6-10

FIGURE 6-10 Alarm and hysteresis definitions

 All above mentioned entities MUST be set as the defaults are

extremes (1E+12). If they are not, no errors will be displayed, but the

[Commissioned] entity will be <False>.

 If the alarm entities are correctly set, but the [Alarm hysteresis] is not,

then any alarms that would raise will never be set off! So watch the

[Commissioned] status.

 Be aware that the alarm status is only visible in the [Primary value]

entity (innage)! It is not visible in the [Secondary value] entity (ullage).

 Although the GPU-protocol always contains the alarm status, the

current software only passes the actual alarm status to this protocol if

the gauge is set to innage control. So when ullage status is asked for

by the GPU-protocol, NO alarm statuses are displayed.

Workaround solution: Set the GPU records to innage.
