Reset energy meter (Addr. 507)
The real, apparent and reactive energy meters can only
be reset simultaneously.
Set "001" for address 507 to reset the energy meter.
If you reset the energy meter, the data will
be lost.
To avoid data loss, you should read
and save the measured values before de-
letion using the GridVis software.
C
Phase sequence
The voltage phase sequence and the phase L1 frequen-
cy are displayed on the screen.
The phase sequence shows the three-phase system se-
quence. The rotary field usually rotates to the "right".
The voltage measurement input phase sequence is che-
cked and displayed in the UMG 96RM-EL. If the string
moves in a clockwise direction, this means that the ro-
tary field rotates to the "right"; if the string moves in a
counter-clockwise direction, this means that the rotary
field rotates to the "left".
The field rotation can only be determined when
the measurement and operating voltage inputs are fully
connected. If a phase is missing or two equal phases are
connected, then the phase sequence is not determined
and the string is not moving.

ply frequency (50.0)

Prior to commissioning potential produc-
tion dependant contents of the energy
counter and min/max values have to be
deleted.
