Messages of Abnormal Operations

Under abnormal communications, the power meter can send out messages via Modbus (codes shown
below), informing the reason why the main station experienced abnormal situation.

Abnormal Message Code

Name

Description

0x01

Illegal Function

Illegal functional code

0x02

Illegal Data Address

Address of data read or written is illegal

0x03

Illegal Data Value

Illegal data format

(such as incorrect data length)

0x04

Slave Device Failure

Slave device fails to follow commands

Based on start/stop status for the 29 types of alarm settings (register location 0x3E~0xFF) under
abnormal situations, the power meter records the type and time of the alarm occurred in the register
location 0x0A01~0x0ACF. The types of alarms and their descriptions are as follows:

Alarm

Number

Alarm Type

Description

1

Over-current

Average current is higher than alert value

2

Low current

Average current is lower than alert value

3

Over natural current

Natural current is higher than alert value

4

Over line voltage

Average line voltage is higher than alert value

5

Low line voltage

Average line voltage is lower than alert value

6

Over phase voltage

Average phase voltage is higher than alert value

7

Low phase voltage

Average phase voltage is lower than alert value

8

Over-voltage imbalance

Rate of voltage imbalance is higher than alert value

9

Over-current imbalance

Rate of current imbalance is lower than alert value

10

Over active power

Total active power is higher than alert value

11

Over reactive power

Total reactive power is higher than alert value

12

Over apparent power

Total apparent power is higher than alert value

13

Active power factor (leading)

Power factor under leading load is lower than alert value

14

Active power factor (lagging)

Power factor under lagging load is lower than alert value

15

Displacement power factor (leading)

Displacement power factor under leading load is lower

than alert value

16

Displacement power factor (lagging)
