Usage and display
The usage of the UMG 96 is carried out via the keys one and two. Measured values and programming data are
indicated on the liquid crystal display. You must distinguish between
Indication mode and
Programming mode.
By entering a password, you can avoid unintentional change of programming data.
Indication mode
In indication mode you can scroll through the programmed measured value indications by using the keys 1 and
2. When the device is delivered, you can call up all measured values shown in table 1. For each measured value
indication, up to three measured values are indicated. The measured value rotation allows to indicate all se-
lected measured values one after the other with a selectable changing time.
Measured values
One measurement is carried out each second. The average is build from the detected values and indicated.
By taking the mean of the measured values, a large change of the input signals of the indicated measured
values appears after 4 second, and can be reduced to 95% of the input signal. The indicated measured value for
reactive power can reach 95% of the input signal after 8 seconds at large changes!
Mean values
For currents and power, additional averaging times in the range of 5 to 900 seconds can be set. These measured
value are marked with a horizontal bar above the measured value.
Energying hours meter
The energying hours meter detects the time, which the UMG96 is under operation. The time can be measured
with a resolution of 15 minutes and indicate in hours.
The energying hours meter cannot be deleted.
Programming mode
In programming mode the settings, which are necessary for the operation of the UMG 96, can be indicated and
changed. Pressing the keys 1 and 2 simultaneously for about 1 second, you reach programming mode via the
password indication. If no user password is programmed, you reach the first programming menu directly. The
programming menu is marked with the text „
PRG
“ in the display.
With key 2 you can change over between the following programming menues:
- Currect transformers,
- Voltage transformers,
- Output K1, switching output / pulse output,
- Output K2, switching output / pulse output,
- Minimum pulse width,
- Averaging times (bimetallic function),
- Rotation time of measured value rotation,
- Measured value rotation and measured value selection,
- Delete minimum and peak values,
- Delete energy,
- LCD contrast,
- Software Release,
- User password.
If you are in the menu programming mode, and no keys are pressed within 60 seconds, or you press the keys 1
or 2 simultaneously for about 1 second, you return to the indication mode.
