3) 

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.
