ENTES EPM 07S digital powermeter User manual

Below you will find brief information for digital powermeter EPM 07S. The EPM 07S digital powermeter is a 3-phase device designed for measuring voltage, current, power, energy, and power factor. It features a Modbus communication protocol for data transfer and a user-friendly interface for setting up parameters. Additionally, it provides energy pulse outputs for integration with external systems, demand monitoring, and maximum demand recording.

EPM-07S DIGITAL POWERMETER
FUNCTIONS OF BUTTONS
When W led lights,it shows max.power values which are measured
instantaneously and it shows total average demand values.
Also it is used for moving upwards in the menu.
When W led lights,it shows min.power values which are measured
instantaneously and it shows total average demand values.
Also it is used for moving downwards in the menu.
It is used for passing between parameters such as VL-N, VL-L, A, W, VAr,
VA, kWh, kVArh, cosj. When it is pressed for 5 seconds, adjustment
mode is entered. In the adjustment mode it is used for saving parameters
and moving to the sub menu.
In the adjustment mode, it is used for entering to the upper menu or
it is used to quit from the adjustment mode without saving the values.
EPM-07S is a 3-phase digital powermeter and energymeter which measures:
-Phase-Neutral voltage (VL-N)
-Active Power (W)
-Active Energy (kWh)
-Phase-Phase voltage (VL-L)
-Reactive Power (VAr)
-Reactive Energy (kVArh)
-Current (A)
-Apparent Power (VA)
-Cosj
These values are displayed by using SET button (
) First 3 displays show L1,
L2 and L3 phase values and the 4th display shows total value of each selected
measured value ( V L - N , V L - L , A, W, VAr, VA, kWh, kVArh or Cosj).
EPM-07S also measures Maximum Demand, Demand, maximum and minimum
values of power. EPM-07S has MODBUS serial interface.

Current Transformer Ratio Setup
In this menu, current transformer ratio is adjusted.
Note: If the current transformer is not used between the system and EPM-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-07S; Current transformer ratio is entered as
= 250/5
= 50 .
Press SET button 5 seconds
(Ctr menu is displayed)
Operating Principle:
Press SET button (The number which
is the last digit of second display
blinks)
EPM-07S displays the energy and power values by multiplying voltage and current
ratios by values read from input. So, the displayed values are the real values of the
system.
By using UP-DOWN buttons enter to
the first digit of desired value.
Energy Pulse Outputs
EPM-07S has 2 Energy Pulse Outputs; Pul1, Pul2.
Pul1 (Reactive Energy Pulse Output): A 400msec. pulse output is given, if measured
energymeter value increases 1 KVArh. Pul1 is used for Reactive Inductive energy
values.
Pul2 (Active Energy Pulse Output): A 400msec. pulse output is given, if measured
energy meter value increases 1KWh. Pul2 is used for both (Active Import) and
(Active Export) energy values. Min. pulse period is 1.6 sec.
Press SET button (First number of
the third display blinks). If you did not
enter the fourth digit correct, you can
reentry by pressing the ESC button.
000
By using UP-DOWN buttons, enter
to the third digit of desired value.
Demand and Maximum Demand
Demand is average of power for the demand time. Demand time can be changed
between 1-60 minutes.
Maximum demand is the max. value of the average power values measured during
demand time. If the new average value exceeds the maximum demand value, the
new demand value is recorded as maximum demand.
Press SET button (The number which is in the middle of the third
display blinks. If you did not enter the third digit correct, you can
reentry by pressing the ESC button.
By using UP-DOWN buttons, enter to the second digit of
desired value
Watching of Min.,Max. and Demand Values:
Min. and Max. values are defined for Active Power (W),reactive power (VAr) and
apparent power (VA). Demand values are defined for total active power (SW),total
reactive power (SVAr) and total apparent power (SVA). When these power values
are displayed, if UP button is pressed, maximum demand values for total active
/ reactive / apparent power are displayed. If DOWN button is pressed demand
values for total active / reactive / apparent power are displayed.
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 smallest value of the measured values in demand time. If
the smallest value of the measured values (for example 15 minutes) in demand
time is greater than the demand value which was stored before, it is stored as
new demand value.
When one of defined parameters is displayed, if UP/DOWN button is pressed,
min., max or demand values are displayed. When an undefined parameter is
displayed, if UP/DOWN button is pressed, instant value is continued to display.
For example when power factor is displayed, instant values are continued to
display because min., max. and demand values are undefined for this parameter.
Press SET button (The number which is the last digit of third display
blinks). If you did not enter the second digit correct, you can reenter by
pressing the ESC button
By using UP-DOWN buttons, enter to the last digit of desired value.

MPR-SW Software is designed for use with EPM-07S device and analyze its
measurement values. MPR-SW is able to view realtime measurements and parameters
on a PC screen. The software records all parameters and values into a database for
future graphical analysis. The Graphical Analysis is designed flexible for view past
records in hour,day and month periods. Inductive/Reactive and Capacitive/Reactive
values can be viewed on the main window. Energy reports can also be viewed
between specific dates.
You may change setup parameters using the MPR-SW Software: Set Transformer
ratios, Reset Energy and Demand values and change the device address up to 247.
MPR-SW can communicate with multiple (max. 247) EPM-07S devices.

Clicking the START button on the main window, starts the real time analysis of
EPM-07S device values. SETTINGS button is for setting up communication
parameters (Adress, Parity, Baud Rate) between the PC and EPM-07S device. Both
side parameters should be the same for correct data transmission. There are CLEAR
ENERGY and CLEAR DEMAND buttons for resetting those values. Transformer
ratio is able to setup with the TRANS.RATIOS button on the main menu.

Frequently asked questions

The EPM 07S is a digital powermeter designed for measuring voltage, current, power, energy, and power factor in a three-phase electrical system.

The EPM 07S utilizes the Modbus RTU protocol for communication with a computer via an RS-485 serial interface.

The EPM 07S has two energy pulse outputs: Pul1 for reactive energy and Pul2 for active energy. Pul1 is used for reactive inductive energy values, and Pul2 is used for both active import and export energy values.

The demand time can be programmed between 1 and 60 minutes using the 'dt' menu, which allows you to customize the averaging period for power measurements.

Yes, the EPM 07S provides options to clear energy and demand values through the 'Clr dE' and 'En' menus, respectively.
