1.3. Error display
See the following table for each "Error information" display and its contents (status). Display order is ①②③④⑤⑥ .
2. Displaying the protection history mode
2.1. Operation specifications
ERROR MODE(displaying the protection history)
When started up, the error information is displayed.
Starting up:
With the "MENU" and "STATUS" buttons pressed, press the "ON/OFF" button to turn the power on. The error (protection
history display) mode is set.
Then, press the "STATUS" button to turn on the FL display.
2.2. About the display on the FL display
When the "STATUS" button is pressed after setting the error (protection history display) mode, a history like the one shown
below is displayed, depending on the conditions.
(1) Normally (when there has been no protection incident)
(2) For ASO/DC (when the last protection incident was ASO or DC protection)
(3) For THERMAL (when the last protection incident was THERMAL protection)
When the "STATUS" button is pressed again after the above protection history is displayed, the normal display reappears.
