General Information

EPM-34 is designed to measure the phase currents in 3 phase systems.

Applications of EPM-34

1) It can measure Phase Currents (IL) in 3 phase systems.

2) You can observe demand and max. demand values of measured currents with

2 different periods, also the calculation time for demand and max. demand values
can be determined from the dE-t (demand time) menu.

3) Current transformer ratio can be programmed,

[1....1000 (for X/5A), 1....5000 (for X/1A)]

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

change of the setting by unauthorized person.

Specific Functions of Buttons:

While device is in the measurement mode, some buttons and button groups have
below special functions.

In order to set CT ratio. In the measurement mode;

Press SET button (Ctr is displayed.)

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 4th digit value by scrolling UP/DOWN buttons.

Press SET button (4th digit of second display blinks. If you set 3rd
digit value incorrect, you can set again by pressing ESC button.)

Press SET button for 3 secs.(CUr- rEnt trF menu is displayed)

Press SET button (Ctr menu is displayed)

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

Current Transformer Ratio

In this menu, current transformer ratio is set.

[1 ...... 1000 (for X/5A) between, 1 ...... 5000 (for X/1A)] a can be entered

Note: If the current transformer is not used between the system and
EPM-34, CT ratio must be set as 1.
For example: If a current transformer with 30 A / 5 A is used between
the system and EPM-34, CT ratio must be set as 6. (30/5=6)

Press SET button (1st digit of second display blinks)

By using UP/DOWN buttons, find SAUE SEt yES

Current transformer secondary value setting

In this menu, current transformer secondary value can be set as 5A
or 1A.

Note: If the secondary value is changed from 5A to 1A, Ctr (current
transformer ratio) value is set as 5 times of previous value automatically.
If the secondary value is changed from 1A to 5A, Ctr (CT ratio)
value is set as 1/5 times of the previous value automatically.
