3.1 Panel przedni

Rysunek 1: Front Panel of the LM8-RR4D Load Cell Indicator. It features a large red LED display for Process Value (PV) and a smaller green LED display for Set Value (SV). Indicators for 'LM' (Limit), 'g', 'AL1', 'AL2', 'AL3', 'T' (Tare), and 'Kg' are also present. Control buttons include 'SET', 'M' (Mode/Shift), 'Up', and 'Down'.

• Wyświetlacz PV: Large red LED display showing the current measured weight (Process Value).
• Wyświetlacz SV: Smaller green LED display showing the set point or parameter value (Set Value).
• Wskaźniki: 'g' (grams), 'Kg' (kilograms), 'T' (Tare), 'AL1', 'AL2', 'AL3' (Alarm indicators), 'LM' (Limit).
• Pikolak:
  • ZESTAW: Enters parameter setting mode or confirms settings.
  • M (Mode/Shift): Used to cycle through modes or shift digits during setting.
  • W górę (▲): Zwiększa wartości lub umożliwia nawigację po menu.
  • W dół (▼): Zmniejsza wartości lub umożliwia nawigację po menu.

3.2 Rear Panel & Wiring Terminals

Rysunek 2: Rear Panel of the LM8-RR4D Load Cell Indicator, displaying numbered screw terminals for power, load cell input, and relay outputs. The wiring diagram is also visible on the label.

The rear panel provides all necessary connections for power, load cells, and relay outputs. Refer to the wiring diagram printed on the device label for specific terminal assignments.

4. Konfiguracja i instalacja

4.1 Montaż

The LM8-RR4D is designed for panel mounting. Ensure adequate space for ventilation and wiring connections. Secure the device firmly in the panel cutout.

4.2 połączeń przewodów

Przed wykonaniem jakichkolwiek podłączeń należy upewnić się, że zasilanie jest odłączone. Refer to the wiring diagram on the device label and Figure 2 for terminal identification.

1. Power Supply (AC 220V/110V): Connect the appropriate AC power supply to the designated terminals (e.g., 110V/220V, N, L). Ensure the voltage matches your local supply and the device's setting.
2. Load Cell Input:
   • Podłącz wzbudzenie ogniwa wagowegotage wires (EXC+, EXC-) to the corresponding terminals.
   • Connect the load cell signal wires (SIG+, SIG-) to the corresponding terminals.
   • The device supports 1 to 4 load cells. For multiple load cells, ensure they are wired in parallel correctly.
3. Relay Outputs (AL1, AL2):
   • Connect your external control devices (e.g., alarms, solenoids) to the AL1 and AL2 relay output terminals.
   • Each relay typically has Common (COM), Normally Open (NO), and Normally Closed (NC) contacts. Wire according to your application's requirements.
4. Communication (Optional, if available): If your model includes RS485 communication, connect the A and B lines to the respective terminals for data transmission.

After all connections are made, double-check wiring for correctness and security before applying power.

5. Instrukcja obsługi

5.1 Włączanie

Once wired, apply power. The LED display will illuminate, showing the current weight (PV) and potentially a set value (SV).

5.2 Podstawowa obsługa

• Zeroing/Tare: Pressing the 'M' button briefly may perform a tare function, setting the current weight to zero. Consult the full manual for specific tare procedures.
• Wybór jednostki: The 'g' and 'Kg' indicators suggest unit selection. This is typically done through parameter settings.

5.3 Parameter Setting and Calibration

The LM8-RR4D requires calibration to ensure accurate weight readings. This involves setting zero and span points using known weights.

1. Wejdź w tryb ustawień: Press and hold the 'SET' button for a few seconds to enter the parameter setting mode. The SV display will show a parameter code.
2. Nawigacja po parametrach: Use the 'Up' (▲) and 'Down' (▼) buttons to scroll through different parameter codes.
3. Dostosuj wartość parametru: When the desired parameter code is displayed, press 'SET' again to view its current value. Use 'Up' (▲) and 'Down' (▼) to adjust the value. The 'M' button may be used to shift digits.
4. Zapisz i wyjdź: Press 'SET' to confirm the value. To exit the setting mode, press and hold 'SET' again, or the device may automatically exit after a period of inactivity.

Specific parameter codes and their functions (e.g., zero calibration, span calibration, decimal point, filter settings, alarm set points for AL1/AL2) are detailed in the comprehensive product manual.

6. Konserwacja

• Czyszczenie: Clean the device exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Kontrola: Periodically check wiring connections for looseness or damage. Ensure the mounting is secure.
• Rekalibracja: If accuracy drifts or after significant environmental changes, recalibrate the device using known weights.
• Składowanie: If storing the device, do so in a dry, dust-free environment within the specified temperature range.
