Ankerui ADL Energy Meter

1Ankerui ADL Energy MeterOverview:

The ADL200 single-phase electronic energy meter is mainly used to measure single-phase active energy in low-voltage networks, and can also measure voltage, current, power, and other electrical quantities. It can also be equipped with RS485 communication function to facilitate users' electricity monitoring, collection, and management. It can be flexibly installed in the distribution box to achieve sub item energy measurement, statistics, and analysis for different areas and loads.

Diagnostic analysis and troubleshooting methods for 6 common faults

6.1 Auxiliary power supply failure

Fault manifestation: The instrument flashes or does not light up after being powered on

Ankerui ADL Energy MeterTroubleshooting:

1. Check whether the wiring of the auxiliary power supply is consistent with the wiring diagram of the instrument, and whether there is any looseness or detachment in the wiring.

2. Use a multimeter to measure whether the input voltage of the auxiliary power supply is within the normal operating voltage range of the instrument.

6.2 Signal input fault

Fault manifestation: The instrument displays inaccurate power or energy counting after being powered on.

Troubleshooting: Switch the instrument display interface to the power (active power P, power factor λ) interface, check if the power display is negative and if the power factor is between 0.9-0.95, and then check if the current signal line inlet and outlet are reversed (i.e. the current inlet must be consistent with the instrument inlet), and be consistent with the wiring diagram on the instrument.

6.3 Communication Failure

Fault manifestation: The instrument cannot communicate normally with the upper computer after being powered on.

Troubleshooting:

The voltage value between the communication outputs A and B of the measuring instrument should be between+(4.4-4.5) V.

2. Check if the communication wiring method is correctly connected according to the wiring diagram requirements (i.e. the communication wiring terminals A/B of the instrument should correspond to the communication serial ports A/B).
