BA524G-SS-PM bargraph.
One of the selectable bargraph formats

Fig 19 Displayed value and setpoints on bargraph
The bargraph area below the low alarm setpoint
and the area above the high alarm setpoint are
activated.
The displayed variable is represented
by an activated bar which moves between these
low and high alarm setpoints.
When the activated bar representing the displayed
variable is adjacent to the area representing the
low or high alarm setpoints, the bar flashes.
When a displayed variable equals the low or high
alarm the complete bargraph representing the
activated alarm flashes irrespective of whether the
alarm output has been delayed or cleared.
For this function to operate
5P1
must be
conditioned as a low alarm and
5P2
as a high
alarm;
5P1
must always be less than
5P2
.
Incorrect configuration is shown by a flashing
bargraph scale with no activated bars.
