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 to 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.)
