Quickstart
Multifunctional voltage relay
Intended use
The multifunctional voltage monitoring relay VMD461 monitors frequen-
cies, undervoltages and overvoltages in DC, AC and 3(N)AC systems. The
phase voltages and/or line-to-line voltages are measured as r.m.s. value
and are continuously shown on the device display. The measured value re-
quired to trigger the alarm relay is stored. The VMD461 features additional
measuring functions for:
 ROCOF df/dt
 Vector shift monitoring
 Unbalance monitoring
 Phase sequence monitoring
The corresponding ANSI codes for all available measuring functions are provided.
Configurable delay times allow considering special installation-specific properties (e.g. device-specific
start-up procedures). The VMD461 requires an external supply voltage.
The optional use of a CD440 coupling device extends the voltage range that can be monitored to DC/
3AC 1200 V or 1AC/3NAC 690 V. Any other use than that described in this manual is regarded as impro-
per. The quickstart does not replace the manual of the device. Download: www.bender.de/manuals

Danger of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
 An electric shock
 Damage to the electrical installation
 Destruction of the device
Before installing and connecting the device, make sure that the installation has
been de-energised. Observe the rules for working on electrical installations.

Wiring
Depending on the application, connect the device according to the following wiring diagrams..
Legend wiring diagrams
* Explanation: NC (closed in non-operating state)
NO (open in non-operating state)
off (switched off)
The VMD461 can be opera-
ted without a CD440 in ap-
propriate power supply
systems (230/400 V).
Risk of unwanted device
failure!
Do not supply device from the
monitored system. Pay attention
to maximum supply voltage.

Initial commissioning
When commissioning the device for the first time you have to:
 Select a language (English, German, French) (menu 4.2).
 Set date and time (menu 4.3).
You can only change settings in the menus after the settings listed above have been carried out
.
User interface
Legend
The contrast of the LC display can be adjusted to any ambient brightness.
Select the contrast ratio from an infinite loop display. Simultaneously press and hold
down the buttons "INFO" and "MENU" until the display text is clearly readable. After
reaching a black display, the contrast setting process starts again with a white dis-
play.
Element
Power On LED, green;
lights when the voltage supply is available and the device is in operation;
flashes when the device is being started or when an internal device error has occurred
ON Alarm LEDs, yellow: installation switched off
Only ALARM 1 lights: alarm relay K1 has tripped
Only ALARM 2 lights: alarm relay K2 has tripped
ALARM 1 and ALARM 2 light: response value violation of voltage or frequency, df/dt, vec-
tor shift detection, unbalance, phase sequence, remote trip

Toggling between the individual displays
You can toggle between the
different displays by using
the four device buttons. De-
pending on the type of dis-
play (standard display,
alarm display, menu display,
info display), the meaning
of the buttons is different.
The picture below illustrates
which button is to be
pressed for accessing the in-
dividual display. First, you
have to distinguish bet-
ween an alarm condition
and no alarm condition..
LEDs
The state of the VMD461 can be determined by means of the LEDs. The following table provides an over-
view of the possibilities.
MENU Standard display: Toggle between standard, menu and alarm display
Menu display: button
