Entes EVM-35-96 Scheda Tecnica

EVM-35  is designed to measure the phase-phase voltage, phase neutral voltage
of system.

Application of EVM-35
1)  It can measure voltage for each phase in 3 phase 
systems with neutral and without neutral.
2) Voltage transformer primer ratio (1-40000) and seconder ratio (1-300) can be
programmed

.

3) A password can be arranged from PASS CodE menu in order to prevent 

change of the setting by unauthorized person.

1... Display of L-1 Phase:It shows L-1 phase-neutral voltage and L1-L2 phase-phase

voltage.

2... Display of L-2 Phase:It shows L-2 phase-neutral voltage and L2-L3 phase-phase

voltage.

3... Display of L-3 Phase:It shows L-3 phase-neutral voltage and L3-L1 phase-phase

voltage.

4... V L-N LED: Phase-Neutral Voltage
5... V L-L LED: Phase-Phase Voltage
6... ESC Button. Used to quit from the menu. Also in the measuring mode, used to
scroll between L-N and L-L values.
7... DOWN Button
8... UP Button
9... SET button. It is used to enter into the menu and to save the values.
       If SET button is pressed for 3 seconds in the measurement mode, you can 
       enter into menus.

Primary and secondary values of Voltage Transformer ratio can
be programmed in this menu.

Note: Enter the primary value as 00100 and secondary value as
100 if there is no voltage transformer is used between EVM-35
and system.

For example; 

If there is 34500V/100V voltage transformer is used

between EVM-35 and system;
      Primary voltage transformer value =  34500,
      Secondary value = 100 is set.

Primary value for voltage transformer is programmed in this
menu. This value can be entered between 1-40000.

In order to enter the voltage transformer primary value; press
SET button for 3 sec. in measurement mode
(UoL- tAGE trF is displayed)

Press SET button, Prý menu is displayed. (New value is entered but it is

not executed yet. In order to set the new value, please follow below

steps.)

Press ESC button one by one until SAUE  SEt  no is displayed.

Press SET button while SAUE  SEt  yES is displayed. (If you press

ESC button or select “no” option instead of “yES”, new data is

cancelled and the previous data is set.)

Find 5th digit of the value which you want to enter by scrolling UP/DOWN
buttons.

Press SET button (most right digit blinks in 2nd display. If you set 4th

digit value incorrect, you can set again by pressing ESC button)

Find 1st digit of the value which you want
to enter by scrolling UP/DOWN buttons.

Find 2nd digit of the value which you want
to enter by scrolling UP/DOWN buttons.

Press SET button (2nd digit of second

display blinks. If you set 1st digit value

incorrect, you can set again by pressing

ESC button)

Press SET button (Prý menu is displayed)

By using UP/DOWN buttons, find SAUE SEt yES

Press SET button (Most left digit blinks in 2nd display.)

Enter the other digits similarly by scrolling SET, UP and DOWN buttons.

Secondary value of voltage transformer is entered in this
menu. This value can be entered between 1-300.

Press SET button, SEC menu is displayed. (New value is entered but

it is not executed yet. In order to set the new value, please follow below

steps.)

Press ESC button one by one until SAUE  SEt  no is displayed.

Press SET button while SAUE  SEt  yES is displayed. (If you press

ESC button or select “no” option instead of “yES”, new data is

cancelled and the previous data is set.)

Press SET button (Prý menu is displayed)

Enter the 3rd digit value by scrolling

UP/DOWN buttons.

Press SET button (3rd digit blinks in 2nd

display).

By using UP/DOWN buttons, find SAUE SEt yES

Find SEC menu by scrolling UP/DOWN

buttons.

Enter the 4th digit value by scrolling UP/DOWN buttons

Press SET button (4th digit blinks in 2nd display.

(If you set 3rd digit value incorrect, you can set again by

pressing ESC button).

Find 5th digit of the value which you want to enter by scrolling
UP/DOWN buttons.

Press SET button (most right digit blinks in 2nd display. If you set

4th digit value incorrect, you can set again by pressing ESC

button)

In order to enter the secondary value; press SET button for 3 sec.
in measurement mode (UoL- tAGE trF is displayed)

After making the connections of the device as given in user manual, voltage is
supplied. Required settings must be done by using menus in order to have the
correct measurements and applications.
