More Information
The voltage relays MK 9064N and MH 9064 of the varimeter family pro-
vide a solution for an optimised monitoring of the function of an electrical
device. Single-phase AC and also DC can be measured, undervoltage,
overvoltage and voltage window are monitored and the measured value
is displayed on the front.

The unit needs a connected auxiliary supply.
It is designed for single phase AC/DC measurement.
The LED indicate 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 9064it 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. M11095

Removing the terminal blocks with cage clamp terminals
1. The unit has to be disconnected.
2. Insert a screwdriver in the side recess of the front plate.
3. Turn the screwdriver to the right and left.
4. Please note that the terminal blocks have to be mounted on the
belonging plug in terminations.

Dangerous voltage.
Electric shock will result in death or serious injury.
Disconnect all power supplies before servicing equipment.
- Faults must only be removed when the relay is disconnected
- The user has to make sure that the device and corresponding compo-
nents are installed and wired according to the local rules and law
(TUEV, VDE, Health and safety).
- Settings must only be changed by trained staff taking into account the
safety regulations. Installation work must only be done when power is
disconnected.
- Observe proper grounding of all components
