Operation

Join Zigbee Network

Step 1:

• Operate your ZigBee Controller (Gateway) to add a device.

Step 2:

• Press the button on the device 5 times continuously.
• If the device is not connected to a network, it will directly enter network paring mode, the LED will flash quickly;
• If connected to a network, it will automatically exit the network, the LED will flash 3 times to indicate a successful network exit. After a few seconds, the device will automatically enter network pairing mode, the LED will flash quickly.

Step 3:

• Wait for this process to finish. If the connection is successful, the LED will flash 3 times, otherwise the LED will go off.
• Re-powering the device: if the LED flashes quickly, the device isn’t connected to a network; Otherwise, it has been connected to a network.
• When the device is working properly, the LED flashes slowly with a frequency of 1s. When EEPROM reading is abnormal, the LED flashes once within 1.5s.

Exit ZigBee Network

Method 1:

• Operate your gateway to delete the device, the LED will flash 3 times to indicate a successful network exit. Method 2: Press the button on the device 5 times continuously, the LED will flash 3 times to indicate a successful network exit.

Factory Reset

• Long press the button for over 10s, the LED will flash slowly then stay on for 3s to indicate a successful reset.

Note:

• After the device exits the Zigbee network, the device’s bind table will be cleared. Electrical consumption data will not be cleared unless the device is restored to factory settings or receives a “Reset to Factory Defaults Command” after being added to the network.

Wiring

1. Three-phase wiring way
2. Mono-phase wiring way

Terminals Introduction

• A: Phase A and power supply input B: Phase B input
• C: Phase C input
• N: Neutral terminal
• IA: Phase A current transformer input
• IB: Phase B current transformer input
• IC: Phase C current transformer input
• IN: Neutral current transformer input
• LA: Phase A live (110-240 V) wire
• LB: Phase B live (110-240 V) wire
• LC: Phase C live (110-240 V) wire
• N: Neutral terminal
• L: Mono-phase live (110-240 V) wire
• N: Neutral wire

Note:

• To obtain a value for the combined phase power, one of the phases A, B, or C must be connected.
• The direction of the combined phase current transformer can be ignored, but the A, B, and C phase current transformers have a specific direction when clamped to the lines.
• If the direction is reversed, the active power and power factor will be negative. The current direction for wiring should pass through the current transformer in the S1->S2 direction, as shown in the following figure:

FAQs

Q: What is the power consumption range of the power meter?
A: The power meter is designed for a power input range of 100-240Vac.

Q: How do I reset the device to factory settings?
A: Press and hold the Reset Key on the device for 10 seconds to perform a factory reset.
