When setting the SV value, range for the setting will be limited to 0 ~ 200Ԩ.
Under ON-OFF and PID control conditions, the control output will be forced to shut off if the PV value exceeds the upper/lower limit.
(Alarm output is still normal)

Alarm Outputs
This controller features one or two alarm outputs. A total of 9 alarm settings can be made independently as shown in the table. Additional
settings are provided, such as alarm delay, alarm standby, alarm output hold, and alarm reverse output, as described below:
Alarm Delay Setting: Sets alarm delay time. When action conforms to the alarm setting mode, controller will delay generation of an alarm
signal. An alarm will only be activated when the alarm conditions remains confirmed within the delayed period of time.
a. Alarm Standby Setting: An alarm detection will only be activated when the measured value falls within ±5 range of specified input
value, so as to prevent an alarm activation on start-up if the condition conforms to the alarm setting.
