12.3 KEY CONFIGURATION
CAUTION!
„ The A type OCR is composed of 6 keys and its LCD illuminates for 30s when a key is pressed during its operation.
„ After 30 seconds idle, it returns to the Measurement display.
„ If the ESC/RESET key is pressed during a power failure, the BATT LED will light up indicating the battery residual
charge.
„ If you press the ESC/RESET key while the unit is energized, only the status of the LEDs can be checked, not the
battery residual charge.
„ Only the BATT LED lights up when the ESC/RESET key is pressed. The other LEDs light up for 1 to 2 seconds after
releasing the ESC/RESET key.
„ If the ABW Compact trips on a fault, the identification of the fault cause is indicated by the LEDs.
„ At this moment, the indication LEDs are operated by a separate battery built into the OCR. Therefore, after finding out
the cause of the failure, turn off the LEDs by pressing the ESC/RESET key.

1. The current of R, S, T, N phases are displayed alternately every 3 seconds
2. At this very moment, the inverted triangle moves sideways from left to right to show which
phase is being currently displayed on the LCD, and the bar graphs
below represent the load rate of each phase in scale (40% ~ 110%).
Pressing the TAP key displays only the value of one phase on the screen and the phase value
displayed stops changing. The triangle sign (∆) will appear in the upper right corner of the LCD
screen.
※ This screen freezing can also be applied to other screens.
The phase that will be exclusively displayed can be selected by pressing the cursor up/down.
