
If necessary, enter a value used to specify the
high alarm limit in ‘
H. Lim.
’ and/or the low alarm
limit in ‘
L. Lim.
’. This is used to define the upper
and/or lower limits of the value recorded from
the parameter. If a limit is exceeded the
corresponding alarm in the BeMS will only be
asserted if ‘
H. Enab.
’ and/or ‘
L. Enab.
’ is
enabled (

).
Remember A configured low alarm limit value must be
less than the defined high alarm limit.

If necessary, enable (

) the high alarm limit
(‘
H. Enab.
’) and/or low alarm limit (‘
L.
Enab.
’). This control the high alarm and low alarm indication in the BeMS, when the
value recorded from the parameter asserts an alarm state determined by the value
defined in
‘
H. Lim.
’ and/or ‘
L. Lim.
’. If this field is disabled ( 
) an alarm state will not be
indicated.

If necessary, enable (

) the plot function. This
allows the Trend graph in the BeMS to plot 1000
