Alarm type 

High limit alarm: The alarm action is  deviation setting from the SV. The alarm is activated 

 

if the input value reaches the high limit set value. Character indication:   

Low limit alarm: The alarm action is  deviation setting from the SV. The alarm is activated 

 

if the input value goes under the low limit set value. Character indication: 

 

High/Low limits alarm: Combines High limit and Low limit alarm actions. When input value 

 

reaches high limit set value or goes under the low limit set value, the alarm   

   

is activated. Character indication:

 

 

High/Low limit range alarm: When input value is between the high limit set value and low 

limit set value, the alarm is activated. Character indication:

 

 

Process alarm: Within the scale range of the controller, alarm action points can be set 

 

at random and if the input reaches the randomly set action point, the alarm is 

 

activated. 

 

Character indication: Process high alarm 

, Process low alarm 

 

Alarm with standby function: When the power to the controller is turned on, even if the input 

   

enters the alarm action range, the alarm is not activated. (If the controller is   

   

allowed to keep running, once the input exceeds the alarm action point, the   

standby function will be released.)
