34 AK2-SC 255 Reference Manual RS.8D.M1.22
Each alarm has three fields:
[Alarm level] (List box)
Disabled: The alarm is deactivated, but any settings
remain in memory, so that they will be at hand when
the alarm is reactivated.
Log only: When the alarm occurs, the fact will be
recorded in memory, but the alarm will not be commu-
nicated beyond the SC 255 (over telephone line or
network).
Normal: When the alarm occurs, it will be communi-
cated beyond the SC 255 one time over telephone line
or network, to the locations specified in the alarm
routing screen.
Critical: When the alarm occurs, it will be communi-
cated beyond the SC 255 multiple times to each
destination defined in the alarm routing screen at the
interval set in the alarm routing screen (from 10 to 99
minutes; the default is every 10 minutes).
<Delete>: The alarm settings will no longer appear
on the screen.
[Trip value] (for temperatures, -999.9 to 999.9; for %, 0 to 999.9)
The level at which the alarm timer begins. As long as
the value remains beyond the alarm limit, the timer will
continue to accumulate. Whenever the value falls
within the alarm limit, the timer will be reset to zero.
[Trip time] (0 to 999) The number of minutes that must expire
(with the alarm value beyond the trip value) before an
alarm occurs. Whenever the value falls within the
alarm limit, the timer will be reset to zero.
