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.
