ASJ series residual current operated relay
1 Introduction
ASJ series residual current operated relay can be combined with low voltage circuit breaker or
low voltage contactor to form a residual current protection device, which is mainly used for the TT
and TN system distribution lines with AC 50Hz and rated voltage of 400V and below. It is used to
protect the electrical circuit form ground faults, prevent equipment damage caused by earth fault
current and electrical fire accidents, and can also be used to provide indirect contact protection
against personal electric shock hazard.
Products meet the requirements of GB/T 22387-2016 residual current operated relay.

4.2 Installation Instructions
4.2.1 Installation Steps
ASJ20 series instrument installation method is panel installation, both sides of the buckle
extrusion fixed, the specific operation is as follows:
1) On the switchboard, choose the appropriate place to cut the 45mm*45mm mounting hole;
2) Take out the remaining current relay and remove the fixed buckle;
3) Install the instrument into the distribution board, and then install it with a buckle.
The specific operation is shown in the figure below.
ASJ10 series meters are mounted by the standard DIN-35mm guide rail.

4.2.2 Installation of accessories
Accessories include residual current transformers and magnetic rings. The remaining current
transformer passes through all the phase lines and neutral lines, and is installed in the cabinet with a
firm fixation. The secondary side wiring is connected to terminals 40 and 41 of the instrument
through a magnetic ring. The installation method of the magnetic ring is shown in the figure below.
It is installed near the end of the instrument wiring and the wiring bypasses the magnetic ring for
two laps.

TT system
ASJ is recommended. The earth fault
current is very small and difficult to be
estimated, operating current can not be
reached, and the hazardous voltage will
appear on the shell.
TN-S
system
ASJ can be used. cut off the fault more
quickly and sensitively, improve the safety
and reliability. PE line is not allowed to pass
through the transformer.
TN-C
system
ASJ can not be used, if PEN line is not
iterative earthing, the ASJ refuse to operate;
if PEN line is iterative earthing, ASJ will be
misoperated.
TN-C-S
system
If it is the TN-C system in front of the point
F, ASJ is not allowed; if it is the TN-S
system at the back of point F, ASJ can be
used, but PE line cannot pass through the
transformer.
IT system
ASJ can be applied. The insulation
monitoring device is applied firstly and the
residual current device is applied to prevent
the reduction of insulation in the system and
make it the secondary backup protection,

8Communication Guide
8.1 Overview of Communication Protocol
ASJ10L-LD1A/C residual current operated relay uses Modbus-RTU communication protocol.
The protocol defines check codes, data sequences, etc. in detail, which are necessary for specific
data exchange. The Modbus-RTU protocol uses a master-slave acknowledgment connection (half
duplex) on a communication line, which means that signals are transmitted in opposite directions on
a single communication line. First, the host computer's signal is addressed to the only terminal
device (slave), then the response signal from the terminal device is transmitted to the host in the
opposite direction.
The Modbus-RTU protocol only allows communication between the host (PC, PLC, etc.) and
terminal devices, and does not allow data exchange between independent terminal devices, so that
each terminal device does not occupy the communication line when they are initialized, but only
responds to query signals reaching the local computer.
8.1.1 Transmission Mode
The information is transmitted asynchronously and in bytes. The communication information
transmitted between the master and the slave is in 11-bit word format, which consists of 1 start bit, 8
data bits (the lowest valid bit is sent first), no check bit, and 1 stop bit.
8.1.2 Information Frame Format
Address
Function
data
CRC
1 byte
1 byte
n byte
2 bytes
Address code: the address code is composed of one byte (8-bit binary) at the beginning of the
frame and the decimal is 0-255. Only 1-247 is used in the residual current relay, and other addresses
are reserved. These bits indicate the address of the user-specified terminal device that will receive
the host data from it. The address of each terminal device must be unique. Only the terminal to
which it is addressed will respond to the query containing the address. When the terminal sends back
a response, the slave address data in the response tells the host which terminal is communicating
with it.
Function code: the function code tells the terminal to which it is addressed which function to
perform. The following table lists the function codes used in this series of instruments as well as
their significance and function.
function
definition
Function
03H/04H
Read data
register
Get the current binary value of one or more
registers
10H
Modify multi
register
Set binary values into a series of multiple
registers
Data area: the data area contains the data required by the terminal to perform specific functions
or the data collected when the terminal responds to the query. The contents of the data may be
values, reference addresses, or set values. For example, the function code tells the terminal to read a
register, and the data area needs to indicate which register to start from and how many data to read.
The embedded address and data vary according to the types and the different contents between the
slaves.

14
CRC check code: the error check (CRC) field takes up two bytes and contains a 16 bit binary
value. The CRC value is calculated by the transmitting device, and then attached to the data frame.
The receiving device recalculates the CRC value when receiving byte data, and then compares it
with the value in the received CRC field. If the two values are not equal, an error occurs.
The process of generating a CRC is as follows:
1) Reset a 16-bit register as 0xFFFF (all 1), which is called CRC register.
2) The 8-bit of the first byte in the data frame is XOR with the low byte in CRC register, and
the result is saved back to CRC register.
3) Move the CRC register to the right by one bit, fill the highest bit with 0, and the lowest bit
is out and detected.
4) If the lowest bit is 0, repeat the third step (the next shift); if the lowest bit is 1, XOR the
CRC register with a preset fixed value (0xa001).
5) Repeat the third and fourth steps until eight shifts, this completes a complete octet.
6) Repeat steps 2 through 5 to process the next octet until all bytes are processed.
7) The final CRC register value is the value of the CRC.
In addition, there is a method to calculate CRC by using the preset table. Its main feature is that
the calculation speed is fast, but the table needs a large storage space. This method will not be
described here, please refer to the related materials.
8.2 Introduction to function code
8.2.1 Function code 03H or 04H: register read
This function allows users to obtain data and system parameters collected and recorded by the
device. There is no limit to how much data a host can request at a time, but it cannot exceed the
defined address range.
The following example reads a value from machine 01 at the address 0008H.

Function code 10H allows the user to change the contents of multiple registers. The time and
date in the meter can be written with this function number. The master can write up to 16 (32 bytes)
of data at a time.
The following example is a device with a preset address of 01 date and time of 12:00 on Friday,
December 01, 2009.From Monday to Sunday, 1 to 7 are used instead.
