VOLTAGE MONITORING

EVM-05C

SP Menu (Set points)

High can be adjusted for each phase-neutral orSetpoints

phase-phase voltages separately.

If the voltage of phase-neutral or phase-phase is under the high

set value (Hi),output 1 relay is not activated,output 1 LED is on

and Hi LEDs are off.

If any voltage of the phase-neutral or phase-phase exceeds the

high set value, Hi LED blinks, output 1 relay activates at the end

of adjusted time(Hi Ond), Output 1 LED turns off and Hi LED turns

on continously.

If all phase-neutral or phase-phase voltages are below the high

set value (Hi) as a hysteresis(Hi Hys), output 1 relay releases at

the end of the adjusted time (Hi Ofd), output 1 LED turns on and

Hi LED turns off.

Specific Functions of Buttons:

While the device shows the Instantaneous value, pressing:

:Displays max. Voltage value set .

:Displays min. Voltage value set.

SET +

If the Latch function is selected ON, relay activates when the

value exceeds the adjusted value.Even if the voltage is below

the set value, output relay remains activated until pressing

these buttons at the same time.

ESC

Provides transition between VL-L and VL-N voltages.

:Displays max. Phase-phase voltage, while VL-L

LED is on.

Displays max. Phase-neutral voltage, while VL-N

LED is on.

:Displays min. Phase-phase voltage, while VL-L LED

is on.

Displaying min. Phase-neutral voltage, while VL-N

LED is on.

General Information

Low Set points can be adjusted for each phase-neutral or phase-

phase voltages separately.

If the voltage of phase-neutral or phase-phase is over the low

set value (Lo),output 2 relay is not activated,output 2 LED is on

and low LEDs are off.

If any voltage of the phase-neutral or phase-phase is under the

Low set value, Low LED blinks,output 2 relay activates at the

end of adjusted time(Lo Ond),output 2 LED turns off and low

LEDs turn on continously.

If all phases-neutral and phase-phase voltages are over the low

set value (Lo) as a hysteresis(Lo Hys), output 2 relay releases

at the end of the adjusted time (Lo Ofd), output 2 LED turns on

and Low LEDs turn off.

Low Voltage values are adjusted for each phase and phase-

phase voltages separately.However Lo Hys(hysteresis), Lo

ond(delay time) and Lo ofd are same values for all phase-neutral

and phase-phase voltages.

When the connection type of system is entered, Lo L-1,Lo L-2

Lo L-3 and Lo Hys values change automatically according to the

new connection.

Lo Hys:10 V, Lo L-1:180 V, Lo L-2:175 V, Lo L-3:170 V is

adjusted in star connection.If the connection type is changed

to the delta connection, the device calculates these values as

phase-phase voltage.

Lo L-1: L1-L-2 phase phase voltage:311 V

Lo L-2: L2-L-3 phase phase voltage:303 V

Lo L-3: L3-L-1 phase phase voltage:294 V

Lo Hys :17 V

Hi Hys:10 V, Hi L-1:250 V, Hi L-2:255 V, Hi L-3:260 V in star

connection.If the connection type is changed to the delta

connection, the device calculates these values as phase-

phase voltage.

Hi L-1: L1-L-2 phase phase voltage:433 V

Hi L-2: L2-L-3 phase phase voltage:441 V

Hi L-3: L3-L-1 phase phase voltage:450 V

Hi Hys :17 V

High Voltage values are adjusted for each phase-neutral

and phase-phase voltages separately. However Hi Hys(hysteresis),

Hi ond(delay on time) and Hi ofd (delay o time) are same valueff s

for all phase and phase-phase voltages.

When the connection type is set, Hi L-1,Hi L-2, Hi L-3 and Hi Hys

values change automatically according to the new connection.

EVM - 05C is designed to measure the phase-phase voltage, phase-

neutral voltage and the frequency of system.

It contains 2 output relays to warn the user against under/over voltage

and frequency.

Out 1 relay changes position according to the max.voltage or

max.frequency value set.

Out 2 relay changes position according to the min.voltage or min.frequency

value set.

The device contains the features of Instantaneous trip, Latch function

and adjustable delay time.

Network connection can be used with neutral or without neutral by

selecting or in setup menu.star delta connection

Application of EVM-05C

1-) It can measure voltage for each phase and frequency in 3 phase

systems with neutral and without neutral.

2-) You can observe the existence of phases by following the L1-L2-L3

LEDs on the device.

3-) Min and max. values measured are recorded and displayed.

4-) It warns the user through Output 1 and Output 2 relays when the

measured voltage and frequency values exceed the set value.

5-) It warns the user through Output 2 relay and LED caution by turning

on and off when there is a false phase sequence,

6-) Voltage transformer ratio can be adjusted between 1  4000.

7-) A password can be arranged from pin menu in order to prevent

change of the setting by unauthorized person.

Note:

Example:

Note:

Example:

The voltage value for set points can be adjusted 0300 V in

star connection and 0...500V in delta connection

If the set point value is set to zero (0) for any phase, the

warning is cancelled for the related phase.
