ALARM TYPE AND ACTION (if alarm function is present)
Caution: In any critical application where failure could cause expensive
product loss or endanger personal safety, a redundant limit controller is
required.
When setting an alarm value for an absolute alarm (A 1 t = A b S ), simply set the value at
which the alarm is to occur.
When setting the alarm value for a deviation alarm (A 1 t = d E ), set the difference in value
from the Set Point desired. For example if a low alarm is required to be 5 degrees below
the Set Point, then set A 1 L o to -5. If a high alarm is required 20 degrees above the Set
Point, then set A 1 H i to +2 0 . If the Set Point is changed, the alarm will continue to hold the
same relationship as originally set.
