The unit needs a connected auxiliary supply.
It is designed for single phase AC/DC measurement.
The LED indicates the state.
Green:
On, when auxiliary voltage present
Orange (flashes):
No measurement;
unit in input mode
Red (short On, short Off):
Failure overvoltage
If the measured value is higher then the upper end of scale value, the
display shows the fault message "OL"
The Device is programmable for AC- or DC- measuring.
On AC-measurement the rectified mean value is measured.
On sinusoidal input signals the RMS value is displayed.
After connecting the auxiliary supply to terminals A1-A2 the startup delay
disables the monitoring function so that changes on the input have no
influence on the relay output of the VARIMETER.
The device is in display (RUN) mode and continuously measures the actu-
al values. Pressing
Esc
for more than 3 sec starts the input mode.
If the setting value is exceeded the relay switches and the display indica-
tes this state. The display is inverted, flashes and shows the error.
The fault memory is selectable
With button
the fault memory can be deleted.
On the unit MH 9063 it is possible to assign different functions to the diffe-
rent relays so one can be used as pre-warning and the other as alarm out-
put. Relay output 1 switches when actual value exceeds the pre-warning
setting. If a second setting assigned to relay output 2 the unit gives an
Alarm signal.
