EPM-07 / EPM-07S
General
EPM-07/07S is a microprocessor based device which developed for measuring
the parameters in an electrical network. Measured parameters are displayed
in 4 displays separately EPM-07S has an MODBUS serial communication
interface.
Using of EPM-07/07S:
Parameters (V ; V ; A; W; VAr; VA; Cos ; kWh, kVarh, THD) are monitoredLN LL j
in L1, L2, L3 displays by scrolling UP/DOWN buttons. Total Active ( W), TotalS
Reactive Power ( VAr), Total Apparent Power ( VA) and Frequency (HzS S )
values and average values of these parameters are monitored in 4th display.
Note: VLN LL or V should be selected for displaying the frequency value.
Monitoring Min.- Max. and Max. Demand Values:
Min. and Max. values are defined for V , V , A, W, VAr, VA, W, VAr, VA.LN LL S S S
Demand values are defined for A, W, VAr, VA, W, VA, VAr.S S S
If measured instant value is smaller than min. value which was stored before,
it is stored as new min. value. If measured instant value is greater than max.
value which was stored before, it is stored as new max. value.
Demand value is the average value of the measured values in demand time
(15 minute).
If one of defined parameters is displayed (ie. W) when deman button is
pressed min., max or max. demand values are displayed. When an undefined
parameter is displayed (ie. Cos ) if demand button is pressed, instant valuej
is continued to display.
H-L-M LEDs
H-L-M LEDs are dedicated to displaying the min., max. and max. demand
values according to selected parameters.
H: Maximum Value, L: Minimum Value, M: Max. Demand Value
Energy Pulse Outputs
EPM-07/07S has 2 Energy Pulse Outputs. These outputs give the pulses only
for E-1 (Energy Counter).
Pul1 and Pul2: In o-1 (Pulse1), o-2 (Pulse2) menus which are in the pulse
menu, device give pulse according to selected energy parameters as [Active
energy (ACt, A-I, A-E), Reactive energy (rEA, r-L, r-C)].
Please refer to the pulse menu for the coefficients of energies.
FUNCTIONS OF BUTTONS
In the monitoring mode, it is used to pass between (V , V , A, W,LN LL
VAr, VA, Cos , kWh, kVarh) parameters.j
At the programming mode, it provides to increase value of desired
parameter and pass to the next menu.
In the monitoring mode, it is used to pass between (VLN, VLL, A, W,
VAr, VA, Cos , kWh, kVarh) parameters.j
At the programming mode, it provides to decrease value of desired
parameter and pass to the prevides menu.
If user password is activated and set button is pressed for 3
seconds, a pin code is required in order to enter to the menu.
(This menu is not available in the devices which are adapted
with CT-25.)
In this menu, current transformer ratio is set between 1 - 2000.
Current Transformer Ratio Setup
Note: If the current transformer is not used between the system
and EPM-07/07S, current transformer ratio is entered as 1.
Example: If a current transformer which has a ratio of 250/5A is
used between the system and EPM-07/07S; Current transformer
ratio is entered as 50 (250/5).

Digital Inputs
EPM-07/07S has 2 digital inputs. Digital inputs have 2 fun ctions:
- When a remote device has activated, situation of this device which is
conncected to the digital input, can be monitored according to data register
(Battery, thermostat, circuit breaker and motor position).
- When the digital inputs have activated in Energy Count menu, device will
control the Energy Counters ( It is used for measuring of energyExample:
separately at the using of network and generator).

In displaying mode, it is used for; passing the instant values which
are displayed for min., max. and demand values in displaying mode,
turn back to the previous menu turn back to the previous digit, when
changing the numerical values and quiting the programming mode
without saving.
Press SET button; trA Fo Ctr menu is displayed (In CT-25 adapted
devices, trA Fo trn is displayed instead.)
( trA Fo Utr menu can be displayed by scrolling the UP/DOWNNote:
buttons.)
Enter the blinking digit value by scrolling UP/DOWN buttons.
Switch to the other digits by using SET button, use ESC button to
go to previous digit. After you entered the last digit press SET
button, Pýn ACt oF is displayed. on can be selected by scrolling
UP/DOWN buttons.

activating the new data please follow the below steps).
Press SET button for 3 seconds (trA Fo menu is displayed)
Press ESC button one by one until SAU E SEt yES is displayed.
Press SET button. When SAU E SEt yES is displayed, if you press
ESC button or choose no option instead of yES option by using
UP-DOWN buttons, new data will be cancelled and previous value

Calculation Methods for Active / Reactive Power Values
If the led on the most right side blinks it represents that active powers / reactive
powers direction is negative.
There are two methods for calculating total active and total reactive powers :
1) Active / Reactive power can be calculated by summing import and export
values and displaying as a single value.
2) Active / Reactive power can be calculated according to direction as
import / export.
Note :
1) The dot at the most right digit of the fourth display (During W isS
displayed) represents that displayed value is export active power value.
Vice versa, displayed value is import active power value.
2) The dot at the most right digit of the fourth display (During VAr isS
displayed) represents that displayed value is capacitive reactive power
value. Vice versa, displayed value is inductive reactive power value.
3) The displayed parameter will not change if power is off after 30 seconds
of stand-by (ie. W).
Failure to follow those instructions will result in death or serious injury.
- Disconnect all power before working on equipment..
- When the device is connected to the network, do not remove the front panel.
- Do not try to clean the device with solvent or the like.Only clean with dry cloth.
- Verify correct terminal connections when wiring.
- Electrical equipment should be serviced only by your component seller.
- No responsibility is assured by manufacturer or any of its subsidiaries for any consequences arising out of the use of this material.
- Only for rack panel mounting.
- Fuse must be F type and limit value doesnt exceed 1A.
Precautions For Installation and Safe Use
In CT-25 (120A) compliant models, only CT-25 current transformer must be used.
Other type of CTs have a high risk to damage to device.
No responsibility is assured by the manufacturer or any of its subsidiaries for any consequences arising out of the use of this material.
