4.2.2 Alarm detection display
The alarm value setting is a possible measurement factor (demand current and harmonic, etc.), it displays in case
an input exceeds a set point.
Besides the usual measurement display, the detected factor is displayed on a screen upper case.
In addition, in case setting OFF (not use) as measurement factor, it does not detect.
And in the case of with an alarm-output option, it is possible to do an alarm output (relay make contact) to the outside
simultaneously with a screen display.
Alarm display possible factor) Demand current, Demand, Harmonic distortion factor (current, voltage),
Harmonic 5th conversion content (current, voltage),
Harmonic nth content (current, voltage n＝3, 4, 5, 7, 9, 11, 13, 15),
Voltage, Current leakage
General measurement display. General measurement display (Alarm detection)
・The example of a display at the case of the detection in each alarm factor.
In case the alarm factor is indicating by measurement at the main monitor or the sub-monitor, a measurement value
constitutes a blinking display.
The displays after an alarm return.
In case a return method is automatic reset setting：It returns to the usual measurement display.
In case a return method is manual reset setting
：A detection display and an alarm output hold (in case setting as an alarm output of applicable factor).
The return in this case needs alarm reset operation. Please refer to "4.3.7 Reset" about alarm reset.
