Product Details

AEW100 wireless energy meter

Product Description

1 Overview

AEW 100 wireless measurement module is mainly used for metering three phase active energy on low voltage network. There are functions like RS485 communication and wireless communication on 470MHz in order to help customers check, get and manage the value of energy consumption. This kind of production has the advantage of higher accuracy, more compact and easy installing. It can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of distribution on different areas and different loadings.

4.2 Installing description

1 The mutual inductor adapts the specification of AKH-0.66/K-20 and AKH-0.66/K-36. L1, L2, L3 prick in to A, B, C phase respectively, and especially the A phase and N terminal powered for the AEW100. And A, B, C phase transmits the voltage and current to AEW100 by mutual inductor, and then the AEW100 transmits the single to PC via RS485.
2 The mutual inductor adapts the specification of AKH-0.66/K-10 and AKH-0.66/K-15.

3-phase 4-wire (voltage and current connected via CT)

5 Operating and display
There are 6 LED lights on the surface of the meter represent for L1, L2, L3, pulse, communication, wireless respectively.
L1 light on means L1 phase powered;
L2 light on means L2 phase powered;
L3 light on means L3 phase powered;
Pulse light on each time means one electric pulse output;
Communication light will flash while communicating via RS485;
Wireless light will flash while communicating via wireless module.

FAQ

Common errors check and solve

1 The meter do not light after powered, or one path of voltage indicator do not light.

Suggestion: Please turn the screw to ensure that the meter needle has been punctured and contacted with the cable inner
conductor cable.

2 Meter's wireless communication failure

Suggestion: Please connect RS485 interface on the meter and USB convert to 485 serial port to read the parameters, and
confirm whether the parameters are the same as the upper terminal wireless configuration (channel and spread spectrum
factor). If different, please modify the meter's wireless parameters and retest the master terminal after the same, and if
the same, it may be the meter and master terminal are in a relative long distance. It is too far to communicate or the scene
is seriously disturbed. We can try to use the external antenna at the same time, or consider the newly added wireless
master terminals, and then test it.
