4.3 WiFi Network Connection (TUYA Smartlife App)

1. Download the 'TUYA Smartlife' app from your smartphone's app store.
2. Daftar atau log masuk ke akaun Smartlife anda.
3. Ensure the circuit breaker is powered ON. The 'Signal' indicator light should be blinking. If not, press and hold the 'Press 10s network' button until it blinks rapidly.
4. In the Smartlife app, tap '+' to add a device. Select 'Electrical' > 'Circuit Breaker (Wi-Fi)'.
5. Follow the on-screen instructions to connect the device to your 2.4GHz WiFi network.
6. Once connected, the 'Signal' indicator will become solid.

4.4 RS485 Modbus Connection (Optional)

For RS485 Modbus communication, connect the A and B terminals of the circuit breaker to your Modbus network. Refer to the Modbus protocol documentation for specific register addresses and communication parameters.

5. Arahan Operasi

5.1 Operasi Manual

To manually turn the circuit breaker ON or OFF, use the red toggle switches on the front panel. Push up for ON, push down for OFF.

5.2 Smartlife App Operation

Once connected to the Smartlife app, you can:

• Remotely turn the circuit breaker ON/OFF.
• Set schedules or timers for automatic operation.
• Monitor real-time current, voltage, dan penggunaan kuasa.
• Adjust protection parameters (OVP, UVP, OCP).

5.3 Ciri-ciri Perlindungan

The TOB1S-63 provides the following adjustable protection features:

• Lebih Voltage Perlindungan (OVP): Adjustable range 250-300V. The breaker will trip if the voltage exceeds this set limit.
• Di bawah Voltage Perlindungan (UVP): Adjustable range 150-200V. The breaker will trip if the voltage drops below this set limit.
• Perlindungan Arus Lebih (OCP): Adjustable range 1-63A. The breaker will trip if the current exceeds this set limit.
• Perlindungan Litar pintas: Non-adjustable, inherent protection against short circuits.

Adjust these settings via the Smartlife app interface for the device. After a trip event, investigate the cause before manually resetting the breaker.

6. Penyelenggaraan

The TOMZN TOB1S-63 circuit breaker requires minimal maintenance.

• Periodically inspect the wiring connections to ensure they remain tight and free from corrosion.
• Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
