iTR326A operation
operation display
The ETU needs to display various operation parameters, setting parameters and other values on the
panel
Use LED digital tube to display the value, and use LED indicator to indicate the type of value displayed
ammeter maximum current display
By default, the intelligent controller enters the maximum current display mode of the ammeter to
display the maximum phase current
When the operation display is not the maximum current display mode, there is no key operation within
10 minutes, and the maximum current display mode will be returned automatically

parameter setting and display mode
Parameters (user parameters) that users can set on site can be realized through key operation and LED
digital tube and indicator light display
setting and display of protection parameters
The protection parameters can be set by the user on site. The parameter setting is realized by four
buttons (i.e.
