The FRER Q15E2 meter is housed in a compact enclosure suitable for DIN rail mounting. It features a clear LCD display, control buttons, and various terminal connections for power, measurement inputs, and communication.

Figure 1: FRER Q15E2 Multifunction Meter. This image displays the FRER Q15E2 meter from an angled front-top perspective. The device is beige-colored with a rectangular 2-line LCD screen labeled 'Q15E2' above it. To the right of the screen are three blue buttons: an arrow pointing right, an arrow pointing up, and an 'ENTER' button. The top of the meter features multiple screw terminals, including those labeled '64 65 B- A+ RS485' for communication, '82 83 + -' for auxiliary power, and '60 61 62 63 OUT 1 OUT 2' for outputs. The bottom of the meter also has numerous screw terminals for electrical connections, including those labeled 'L1', 'L2', 'L3', and 'N'. A warning triangle symbol is visible on the top left corner.

4. സജ്ജീകരണം
4.1 മൗണ്ടിംഗ്
The Q15E2 meter is designed for standard 35mm DIN rail mounting. Ensure sufficient space for ventilation and wiring connections.
- Hook the top edge of the meter onto the DIN rail.
- Push the bottom edge of the meter firmly until it clicks into place on the rail.
4.2 വയറിംഗ്
All wiring must be performed with the power supply disconnected. Refer to the wiring diagram provided with the product for specific connection details. The following describes general connections:
- സഹായ ശക്തി: Connect the auxiliary power supply to terminals 82 (+) and 83 (-). Verify the voltage matches the meter's specifications.
- വാല്യംtagഇ ഇൻപുട്ടുകൾ: Connect the phase voltages (L1, L2, L3) and neutral (N) to the corresponding terminals at the bottom of the meter.
- Current Inputs: Connect the secondary windings of current transformers (CTs) to the designated current input terminals. Ensure correct polarity.
- RS485 ആശയവിനിമയം: Connect the RS485 communication bus to terminals 64 (B-) and 65 (A+).
- ഡിജിറ്റൽ ഔട്ട്പുട്ടുകൾ: Connect external devices to terminals 60-63 for digital output functionality as required.

5.1 പവർ ഓണാണ്
Once all wiring is complete and verified, apply power to the auxiliary power input. The meter's LCD display will illuminate and show initial readings or a startup sequence.
5.2 ഡിസ്പ്ലേ നാവിഗേഷൻ
The Q15E2 uses three buttons for navigating through its menus and displaying various parameters:
- മുകളിലേക്കുള്ള അമ്പടയാള ബട്ടൺ: Scrolls through parameters or menu options upwards.
- വലത് അമ്പടയാള ബട്ടൺ: Scrolls through parameters or menu options to the right, or enters a submenu.
- എന്റർ ബട്ടൺ: Confirms a selection or enters a parameter editing mode.
Press the Right Arrow button to cycle through different measurement screens (e.g., Voltage, Current, Power, Energy). Use the Up Arrow button to view different phases or specific values within a screen. Press ENTER to access configuration menus (if enabled).
5.3 പാരാമീറ്റർ കോൺഫിഗറേഷൻ
To configure settings such as CT ratios, communication parameters, or output functions, access the configuration menu. This typically involves pressing and holding the ENTER button for a few seconds or navigating to a specific menu item. Follow the on-screen prompts to adjust parameters. Always save changes before exiting the configuration menu.
6. പരിപാലനം
The FRER Q15E2 meter is designed for long-term, reliable operation with minimal maintenance.

7. പ്രശ്നപരിഹാരം
This section addresses common issues that may arise during the operation of the Q15E2 meter.
7.1 No Display or Blank Screen
- Check Auxiliary Power: Ensure the auxiliary power supply is connected correctly to terminals 82 and 83 and is within the specified voltagഇ ശ്രേണി.
- വയറിംഗ് പരിശോധിക്കുക: Confirm that all power connections are secure and correctly wired.
7.2 Incorrect Readings
- CT അനുപാതം: Verify that the Current Transformer (CT) ratio configured in the meter matches the physical CTs installed.
- Wiring Polarity: Check the polarity of current transformer connections. Reversed polarity will result in negative power readings.
- വാല്യംtagഇ കണക്ഷനുകൾ: വോളിയം ഉറപ്പാക്കുകtage inputs are connected to the correct phases and neutral.
7.3 Communication Issues (RS485)
- വയറിംഗ്: Check RS485 wiring for correct polarity (A+ to A+, B- to B-) and secure connections.
- Baud Rate/Parity: Ensure the meter's communication settings (baud rate, parity, stop bits) match those of the master device.
- ഉപകരണ വിലാസം: Verify the Modbus address of the meter is unique on the bus.
If issues persist, contact FRER technical support.
