User Manual
V4080 is digital fully programmable device from series 4080. It measures voltages from 0V to
270VAC/ 380VDC (if ordered specifically - 600VAC/ 800VDC). V4080 can measure its own power supply
(base, without options, minimum voltage 55VAC/80VDC) or voltage at additional external input (version
“L” or “H”). The device can be purchased with potential-free contacts for remote signalization if
measured voltage goes out of certain programmable limits (option “R”). V4080 is designed to be
mounted on boards in control rooms of electrical substations.

2. V4080 Work
V4080 starts working immediately after power up as described:
Initialization Mode
-Decimal point of least significant digit lights for
about 0.2s
-Display shows moving “Gineers” - for about 3s.
-The device enters normal work mode – shows
instant measured current, one of the LEDs
(low/normal/high) is lit, and if the device is with
“R”-option – one of the relay contacts is closed.
Work mode
The device shows the instant measured voltage
on its display. It continuously monitors and signals if value
is within certain programmed limits (low/hi) via front panel LEDs and relay contacts. If the value is
outside these limits, the display blinks with frequency about 2-3Hz (blinking can be turned off via user
menu). The device will alarm for value outside limits after period of time, set as number of consecutive
measurements out of the limits. It is made this way in order to avoid the possibility of false short-time

signaling. Then, for entering back into normal limits, the voltage must be within the limits plus
programmed hysteresis value, as shown on fig.1. There is no time delay when returning to “within
limits” mode.
V4080 programming
V4080 can be programmed via user menu. The user can enter in the menu by pressing the
“OK” key when the device is in normal working mode. IT IS FORBIDDEN to press any key when the
device is in initialization mode! If V4080 is with option “С” (V4080C), the menu requires user code; the
display shows ‘uSEr’, until “OK” key is depressed. After that the display shows “codE” and the device
waits for four-digit user code to be entered. If the entered code is valid, then the user is allowed to the
menu; and if the code is invalid, the user cannot have access to the menu and the device returns back
to normal working mode. Entering the code is basically four-digit parameter edit (see below). If the
device is without option “C”, user code is not required and the user is allowed to the menu, the display
shows the first parameter in the menu (Hi).
User menu parameters:
-low voltage level (Lo)
Below this level of input voltage V4080 signals for value below limits – with LED and relay
-high voltage level (Hi)
Over this level of input voltage V4080 signals for value above limits – with LED and relay
-display blinking when value is outside programmed limits (bLin)
turns on/off display blinking if the value is outside programmed limits
-hysteresis (HYSt)
This is the hysteresis between voltage entering and exiting “value outside limits” mode ad
signalization
-signalization delay (rdEL)
This is the number of consecutive measurements before the device signals that the voltage is
outside programmed limits
When entering user menu the display shows “Hi” – the first parameter in the menu. Other
parameters can be chosen by pressing ‘Ò’ key, and editing the chosen parameter can be done by
pressing ‘ОК’ key. Exiting the menu can be done only if parameter is not edited at the moment
(i.e. the user can exit the menu only when choosing parameter to edit) by pressing and holding ‘Ò’
key and briefly pressing ‘OK’ key when 'Ò’ is pressed. After exiting the menu V4080 continues to
work normally.
IMPORTANT: When the device is in the menu, it does not measure input value and
therefore does not alarm if the value is – or not – within the programmed limits. All of
the signals remain as they were prior entering the menu!
Parameter editing – if the parameter is chosen by ‘Ò’ key, with ‘OK’ key the user can edit
the parameter. If the parameter has several digits to be entered, with both the keys the digits are edited
one by one: after entering “parameter edit” mode the display shows the current value of the parameters
and the most significant digit is blinking. Blinking of the digit means that it is the current edited digit,
and pressing ‘Ò’ key increments it with 1. After reaching ‘9’ incrementing the digit resets its value to '0'.
Pressing ‘OK’ key confirms the value of this digit and goes to the next digit, which now blinks. After
confirmation of the last digit the parameter is saved and the user goes back to the menu to select
another parameter to edit.
If the parameter to edit has several values or options, then with ‘Ò’ key the user can go round
all the options/values and when selects the correct one, confirms it with the ‘OK’ key and goes back to
the menu.
If version of device is “Х” then no parameter can be edited by the user – all parameters are
written when produced and can only be read.
This table shows the factory default settings and limits for all the parameters in the menu:
Parameter(submenu) Display Limits Default value
High level Hi 0000-9999 1200
Low level Lo 0000-9999 0800
Display blinking bLin on/oFF On
Hysteresis HYSt 0000-0099 0010
Relay delay rdEL 0000-0099 0008
3. Mounting and electrical connection
V4080 should be mounted on
board with opening 43x90mm with
mounting kit, supplied with the device. All
connections must be made with isolated
cables with cross sectional area of
0.75mm2÷2.5mm2. The connections are
shown on the next figure:
С1 ‘Power'/’Voltage measure’
No Description
1, 3 Power supply/measured voltage
2Notused
C2 ‘Input voltage'
No Description
1 Input voltage, plus
2Notused
3 Input voltage, minus
С3 'Relays' – optional
No Description
1,2 NC “high value”
3,4 NC “normal value” (value within limits)
5,6 NC “low value”
If ordered with separate voltage measuring input C2 – measured voltage must be supplied to this input
and the device is powered on C1 with stated power supply; if not - V4080 measures its power supply.
C2 is mandatory for device with options “L” and “H”. C1, C2 and C3 are galvanically isolated with
break-through voltage above 1000VDC.
IMPORTANT: Only qualified personnel, familiar with safety instructions and this user manual
should be allowed to work with V4080!
