The F4 key will call up Limit Programming.
OFF-RATIO WARNING & ALARM SETTINGS
Since the EMO 500 is primarily a Ratio Monitor, Limits 1 and 2 are factory set to be
triggered by an off-ratio condition.
Default values are set at Limit 1 = Warning 5% and Limit 2 = Alarm 10%.
For example: If the RATIO WARNING is programmed at +/- 10%, then the LIMIT 1
contact will close when this event occurs. LIMIT 2 will be similarly activated by the
value programmed in the RATIO ALARM. Note - Press key #5 to review the current
ratio alarm settings and key #9 to review the limit status. Off-ratio alarms can be reset
easily by pressing either F3 (Reset A) or F4 (Reset B).
