5. Инсталација и ожичење

5.1 Мере предострожности

• Ensure all power is disconnected before attempting any wiring.
• Connect the device strictly according to the provided wiring diagrams. Incorrect wiring can cause damage to the meter or the connected system.
• Не прекорачите номиналну запреминуtage and current parameters of the device.
• This device is for indoor use only. Avoid exposure to moisture or extreme temperatures.

5.2 Основни дијаграм ожичења

The meter requires connection to both the power supply and the load through the 100A/75mV shunt. The shunt is critical for accurate current measurement.

Image 5.1: Basic wiring diagram showing connections between power supply, shunt, meter, and load. Note the distinction between large and small terminals on the shunt; current sensor wires connect to the small terminals.

Important: Distinguish between the large and small terminals of the shunt. The current sensor wires must connect to the small terminals for proper operation.

5.3 Solar System Wiring Example

The KETOTEK meter can be integrated into various points of a solar power system to monitor different aspects of performance. Below are examples of how to connect the KT-D138 model to monitor charging, discharging, power generation, and load usage.

Image 5.2: Diagram illustrating four different connection points (1, 2, 3, 4) for the KT-D138 meter within a solar system, allowing monitoring of charging, discharging, power generation, and load usage.

1. Позиција 1: Monitors charging performance. When the battery is discharging, the meter displays 0. Energy accumulation stops until charging resumes.
2. Позиција 2: Monitors discharging performance. When the battery is charging, the meter displays 0. Energy accumulation stops until discharging resumes.
3. Позиција 3: Monitors the power generation of the solar system.
4. Позиција 4: Measures the load usage.

6. Упутство за употребу

The meter features a single button on the right side of the display for various functions.

• Контрола позадинског осветљења: Briefly press the button to toggle the backlight ON or OFF.
• Energy Reset: Press and hold the button for 5 seconds until the energy value (Wh) flashes. Release the button, then briefly press it again to reset the energy accumulation to zero.
• Волtage Alarm Threshold Setting:
  1. Press and hold the button for 3 seconds until the voltage value flashes. This indicates entry into the voltage alarm setting mode.
  2. Briefly press the button to adjust the voltage alarm threshold value. Each press increases the value.
  3. After setting the desired value, press and hold the button for 5 seconds to save the setting and exit the setting mode.
• Складиштење података: The meter automatically stores the last measured energy data when power is removed. This data is retained until manually reset.

7. Одржавање

• Keep the device clean and dry. Use a soft, dry cloth to wipe the display and casing.
• Avoid exposing the meter to direct sunlight, high humidity, or corrosive environments.
• Do not attempt to disassemble or modify the device, as this will void any warranty and may cause damage or injury.
• Store the meter in a cool, dry place when not in use.

КСНУМКС. Решавање проблема

• Мерач се не укључује:
  • Check all wiring connections to ensure they are secure and correct.
  • Проверите да ли је улазна волtage is within the specified range (DC 6.5V - 100V).
  • Ensure the power supply is active.
• Incorrect current reading:
  • Confirm that the 100A/75mV shunt is correctly installed in series with the load.
  • Ensure the current sensor wires are connected to the small terminals of the shunt.
  • Check for loose connections at the shunt or meter terminals.
• Екран је затамњен или трепери:
  • Уверите се да је улазна волtage is stable and within the operating range.
  • Briefly press the button to check if the backlight was turned off.
• Energy (Wh) value does not reset:
  • Follow the energy reset procedure carefully: press and hold for 5 seconds until flashing, then briefly press again.
