2. Safety
2. 1 Intended use
The voltage and frequency monitoring relay VMD460-NA is used for system
and network protection (NS protection) of CHPs, wind, hydroelectric and photovoltaic systems feeding power into the grid.
If inadmissible voltage and frequency values occur on the supply side, the
VMD460-NA has the task of disconnecting the power generation system from
the distribution network by means of a coupling switch.
The voltage and frequency monitoring relay is to be installed and connected
directly at the central meter panel.
The VMD460-NA utilises a separate supply voltage connection.
Power generation systems with an output of > 6 kW
require a separate asymmetry monitoring.
2. 2 Electrically skilled person

Function
3.2 Description of function
The power generation system is only allowed to connect to the public grid
when the country-specific connection conditions are met. Mains voltage and
mains frequency must be within the defined tolerance range.
The devices utilise several separately adjustable measuring channels for:
Voltage drop protection U <, U<<
Rise-in-voltage protection U >>, U10> / U> (depending on standard)
Frequency decrease protection f <, f<<
Frequency increase protection f >, f>>
This satisfies the requirements for static and dynamic network monitoring.
In case of infringements of a limit value or a remote trip signal, the relay K1
(and K2, if necessary) switch and the alarm LEDs light. Reconnection to the
grid is carried out when the national connection conditions to the grid are
met. Pressing the test button ensures that the relays are checked and the required test (trigger test) of the relays K1 and K2 is carried out.
3.2.1 Calculating the average value of overvoltage
(VDE-AR-N 4105, CEI 0-21, C10/11)
The overvoltage U10 is determined by averaging the last 10-minute measuring interval. Always the highest 10-minute average value value U10> of each
of the three voltages monitored between L1-N, L2-N, L3-N will be indicated.
3.2.2 Self test, automatic
The device runs a continuous self test during which internal malfunctions are
detected and shown on the display as error codes. The alarm relays are not
switched during this test.

Function
3.2.10 Passive islanding detection (df/dt)
The VMD460-NA uses a passive method for islanding detection (three-phase
voltage and frequency monitoring).
df/dt
The monitoring of the rate of change of frequency "ROCOF" (df/dt) is an
islanding detection function.
If a section of the network is disconnected by the energy provider, it may happen that the power generation systems located in this section unintentionally
feed this section of the network.
Underfrequency and overfrequency monitoring might not be sufficient to detect this dangerous, uncontrollable state, since the generators try to keep the
frequency at the nominal frequency level.
Due to the unbalance between generated and consumed energy, however,
the frequency fluctuates around the nominal frequency. If this happens at a
certain minimum speed, this is an indication of islanding, hence the power
generation system will be disconnected by the VMD460-NA.
As soon as the rate of change of frequency is below the response value

4. Installation, connection and commissioning
Danger of electric shock!
Make sure that the installation area is disconnected
from any electrical source .
Consider the data on the rated voltage and supply
voltage as specified in the technical data!
4.1 Unpacking
Unpack all the parts supplied with the system. Avoid sharp-edged tools
that may damage the content of the packaging.
Compare your order with our delivery note to check that you have
received all products in full. The article numbers and type designation
printed on the nameplates provide an easy means of uniquely identifying each device.
Check all parts supplied for any evidence of damage in transit.
Equipment damaged in transit must not be used. If a device has sus-
tained damage, please contact Bender. Details of who to contact are
indicated on the delivery documents.
When storing the devices in an environment where the temperature is
wintry and cold:
Leave the devices to stand for 3 to 4 hours at room temperature before
connecting the power supply. When the devices are moved from a cold
to a warm environment, condensation will be evident on all parts.
Putting damp devices into operation risks damaging electrical components and there is a danger of electric shock on contact.
4.2 Back-up fuses
Equip the supply voltage of all system components with fuses. IEC 60364-4-43
requires protective devices to be used to protect the component in the event
of a short circuit. We recommend the use of 6 A fuses.

5.4.2 History
The fail-safe history memory stores up to 300 events (alarms, tests) with information about alarms and acknowledgements and the time the event happened. If the history memory is full, the oldest entry will be deleted in the
event of an alarm to create space for the new entry (FIFO principle).
For details about erasing the entire history memory manually, refer to
"Chapter 5.4.4 System" on page 38.

Response values for NS protection may only be changed in
consultation with the network operator!
Settings can be password protected. If the password is activated (enabled), all
settings continue to be displayed. When an attempt is made to change settings, the password entry screen appears automatically:
Once a valid password has been entered, access will be granted to settings in
all menus (except the Service menu) until menu mode is exited.
If you can't remember your password, contact the Bender Service.
In principle, all preset response values can be changed, if this should be necessary. The values can be changed in the third level of the menu (column
"twice ") using .
There are two different ways to exit the setting menu:
Save and exit: „“

6. Maintenance
Repeat test of the trigger circuit by the system operator
The system operator must ensure that the equipment required for parallel
operation with the low-voltage network is always in proper technical condition. To this end, it is required to have an electrically skilled person check the
protective devices for proper functioning at regular intervals. This requirement is deemed to be satisfied for normal and environmental conditions if the
test intervals mentioned in BGV A3 are adhered to. The repeat test shall include at least the following:
Check of the environmental conditions (pollution, mechanical or isola-
tion damage).
A tripping control of the coupling switch.
Press the "TEST" button to trigger the coupling switch.
Tripping must be visualised by the coupling switch.
The trigger circuit NS protection/coupling switch, in the wiring diagram of this
operating manual consisting of K1/K2 and coupling switch 1/coupling switch
2, separates the power generation system from the public low-voltage grid.
By checking the trigger circuit regularly, sticking of the contactors can be
detected at an early stage.
