5. Орнотуу
5.1. Орнотуу
- Электр энергиясын өчүрүү: Before starting any wiring, ensure that the power supply to the circuit where the smart switch will be installed is completely disconnected at the main breaker.
- Монтаждоо: Secure the EWB2CH-B1 module in a suitable enclosure or mounting location, ensuring it is protected from environmental factors and accidental contact.
5.2. Электр зымдары боюнча нускамалар
Refer to the labels on the device for correct terminal identification. The device has an 'Input' section for power and an 'Output' section for dry contact switching.
- Power Input (DC/AC 7V-32V): Connect your DC or AC power supply (within the 7V-32V range) to the designated 'Input' terminals. Observe polarity if using DC.
- Dry Contact Output (NO, COM, NC): Each channel (R1 and R2) provides three terminals:
- ЖОК (Негизде ачык): The circuit is open (disconnected) when the switch is off, and closed (connected) when the switch is on.
- COM (жалпы): The common terminal for the switch.
- NC (Нормалдуу жабык): The circuit is closed (connected) when the switch is off, and open (disconnected) when the switch is on.
After wiring, carefully inspect all connections to ensure they are secure and correct before restoring power.
6. Иштөө нускамалары
6.1. Кол менен иштөө
The EWB2CH-B1 features two manual buttons, R1 and R2, corresponding to each channel.
- Которуу/күйгүзүү: Pressing a button (R1 or R2) will toggle the state of its respective channel's dry contact output (from open to closed, or closed to open).
- Статус көрсөткүчтөрү: Each button has an associated LED indicator that shows the current state of the channel.
6.2. EWELINK App Control and Pairing
To control the device remotely and access smart features, you need to pair it with the EWELINK application.
- Download EWELINK App: Download the EWELINK app from your smartphone's app store (iOS or Android).
- Катталуу/Кирүү: Create an account or log in to your existing EWELINK account.
- Жупташтыруу режимине кирүү: Power on the EWB2CH-B1. Press and hold one of the manual buttons (e.g., R1) for approximately 5-7 seconds until its LED indicator starts blinking rapidly. This indicates the device is in pairing mode.
- Колдонмого түзмөк кошуу: In the EWELINK app, tap the '+' icon to add a new device. Follow the on-screen instructions to select the device type and connect it to your 2.4GHz Wi-Fi network.
- Контролдоо: Once successfully paired, the device will appear in your EWELINK app. You can now control each channel independently, set schedules, timers, and integrate with other smart home features.
7. Техникалык тейлөө
- Тазалоо: Ensure the device is powered off before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Программалык камсыздоонун жаңыртуулары: Periodically check the EWELINK app for available firmware updates to ensure optimal performance and security.
- Туташуу текшерүү: Occasionally inspect wiring connections to ensure they remain secure.
8. Кыйынчылыктарды
- Түзмөк күйбөй жатат:
- Verify the power input voltage is within the DC/AC 7V-32V range.
- Check all power connections for proper contact and polarity.
- Cannot Pair with EWELINK App:
