Alarm Output; Alarm History; Time Chart Of Alarm Output Function - Omron KE1 User Manual

 Alarm output
• Alarm output upper/lower limit threshold, alarm output hysteresis, alarm output on-delay
can be set.
• Setting hysteresis can prevent frequently turning ON/OFF an alarm even when a
measurement value varies near the alarm output judgment value.
• On-delay is a function that keeps the output OFF for the specified hours and minutes. Set
an optimum value.
• Setting the upper limit threshold of each alarm to the maximum value turns the upper limit
alarm function OFF, while setting the lower limit threshold to the minimum value turns the
lower alarm function OFF. The setting should be made to use only either upper limit alarm
or lower limit alarm.
* Do not use the alarm output function in cases related to safety, e.g., machine control, etc.,
because the function is assumed to detect errors and call attention by sounding a buzzer
or lighting a lamp.
 Alarm history
Histories of alarms generated in the past can be confirmed via communication.
Histories of only 20 alarms generated in the past can be read. If the number of alarms
generated exceeds 20, histories are deleted from the oldest one.
Alarm type, and time of alarm generation: The circuit in which an alarm was generated, and
Alarm release time:
