Section 8 • Alarm and Trip Setpoints

Alarm and Trip Setpoints

Screens may have inverted colors for ease of
readability.
The blower controller continuously monitors opera-
tional and process data and annunciates an alarm and/
or shuts the blower down if any condition becomes ab-
normal. The alarm and trip points for some of the op-
erational and process data are adjustable by the user in
the alarm and trip setpoints screens. The alarm and trip
setpoints are interlocked such that a low alarm may not
be set lower than a low trip, and a high trip may not be
set below a high alarm.
Actual values of the specifi c operational and process
data is shown in the column in the middle of the screen.
Setpoints are only shown for applicable alarm and trip
points.
