 Alarm Outputs 

Two alarm outputs are provided in the machine, a maximum of 3 alarm outputs can be expanded. A total of 19 Independent alarm settings 
can be made as listed in the table. Additional settings are provided, such as alarm delay, alarm standby, alarm output hold, alarm reverse 
output, and alarm peak record, as described as follows:   
a

  Alarm Delay Setting: Sets alarm delay time. When the movement conforms to the alarm setting mode, controller will delay the 

generation of an alarm signal; an alarm will only be activated when the alarm conditions remains confirmed within the delayed period 
of time.   

b

  Alarm Standby Setting: An alarm detection will only be activated when the measured value falls within the ±5 range of the specified 

input value, so as to prevent an alarm activation on the start-up if the condition conforms to the alarm setting.   

c

  Alarm Output Hold Setting: The alarm message will be held when the alarm activates, unless the control switches off the alarm.   

d

  Alarm Reverse Output Setting: An alarm output can be set for NC( Normal close) or NO(Normal Open). 

e

  Alarm Peak Record Setting: For recording the peak value of the alarm signal.
