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:

aAlarm 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.

bAlarm 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.

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

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

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