Deviation Alarm

Also the deviation alarm can only be done on a " Controlling system" because it links the value of the

threshold set point but in some ways is a cross between Process and Band alarm .

For this reasons the deviation alarm acts as a process alarm where the alert threshold is added or removed

from the set point.

Again there are

two possibilities

:

A)

deviation alarm

Up

[M > (SP + SA)]

B)

Deviation alarm

Down

[M < (SP – SA)]

Note:

The band and deviation alarms automatically moving the absolute value of the threshold when you change

the set point value.

The process alarm, however, is indifferent to changes of set points.
