EMD-1ZBS Electricity Power Reader
Introduction
The Energy Meter is a ZigBee Electricity Power reader designed to be used with a digital watt hour meter
supporting LED pulse output port. The E-meter reads the LED pulse from the watt hour meter and transmits the
data to ZigBee network coordinator.
The Energy Meter utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless communication
protocol that is reliable, has low power consumption and has high transmission efficiency. Based on the
IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network and coordinated for
data exchange and signal transmission.
The Energy Meter serves as an end device in the ZigBee network. It can be included in the ZigBee network to
transmit signal upon activation, but cannot permit any other ZigBee device to join the network through the Energy
Meter.
Parts Identification
1. LED indicator
The LED indicator lights up in the following conditions:
- Flashes quickly:
The Energy Meter received LED signal.
- Flashes once:
The Energy Meter is reset.
- Flashes twice:
The Energy Meter has successfully joined a ZigBee network.
- Flashes every 20 minutes
The Energy Meter has lost connection to current ZigBee network
2. Mounting Holes
3. Battery compartment Cover
Remove the cover to insert 2 Alkaline AA 1.5V batteries to power up the
Energy Meter.
4. LED Sensor Jack
Plug the Sensor into this jack to receive LED signal from the watt hour
meter.
5. Function Button
- Press the button once to transmit supervision signal.
- Press and hold the button for 10 seconds then release to reset the
Power Meter.
6. IR Sensor
Attach the IR sensor to the watt hour meter, and plug into the IR sensor
Jack to read data from the watt hour meter.
Features
Battery and Low Battery Detection
The Energy Meter uses 2 Alkaline 1.5V batteries as its power source, It feature Low Battery Detection
function. When the battery voltage is low, the Energy Meter will transmit Low Battery signal to notify ZigBee
network coordinator.
When changing battery, after removing the old batteries, press the function button a couple times to fully
discharge before inserting new batteries
Supervision
T
he Energy Meter will transmit a supervision signal to report its condition regularly according to user setting.
The factory default interval is 30 minutes. The user can also press the Function Button once to transmit a
supervision signal manually.
