Description
Sets the alarm limits for the delta column pressure (pre-
column pressure minus post-column pressure). When
enabled and the delta column pressure falls outside the
set pressure limits, an alarm will be triggered and the
method will be paused. Low alarm is only triggered if
the pressure first exceeds the Low alarm limit for ten
seconds continuously then falls below the Low alarm
limit.
Note:
•
Setting the Low alarm to 0 deactivates the low
pressure alarm.
•
Instruction Alarm delta column pressure is available
only when Column valve V9-C or V9H-C (5-columns)
is selected in the component list.

enabled and the pre column pressure falls outside the
set pressure limits, an alarm is issued and the method
will be paused. Default values for the alarm limits are
set by the values in the column list when a column is
selected in the method and Alarm pre column pressure
is set as a variable. Low alarm is only triggered if the
pressure first exceeds the Low alarm limit for ten sec-
onds continuously then falls below the Low alarm limit.
