Supplementation ----------------------------------------------------------------------------------------------------------------------------------------------------------------
• This unit has only a function to monitor the conditions of occurrence of upper/lower limit alarms and the history of upper/lower limit
alarms (date and time of occurrence and values upon occurrence) on the display unit.
• To monitor the current and electric power as instantaneous values, set the demand time limit to 0 second.
• The upper and lower limits can be set only on the display unit. They cannot be set by CC-Link.
• Each value upon occurrence and date and time of occurrence can be checked only on the display unit. They cannot be read by CC-Link.
On CC-Link, only the alarm status can be checked.
