Resetting to factory defaults (window 99)

The factory defaults are reset by entering “dEF” in window 99. If window 99
shows “USr” it indicates that the settings have been changed to user specific set-
tings.

View alarm message (window 00)

In an alarm condition, the window 00 appears automatically. The window indi-
cates the following alarm conditions. Window 00 flashes at all times.

When the monitor is switched on (power up), the voltage on phases L1, L2 and
L3 is checked. If the wrong voltage is detected, an LU (undervoltage) or OU
(overvoltage) alarm is generated. No relay alarm will be indicated or activated.
