AIM-R100 Residual Current Monitoring Product
1 Introduction
Residual current monitoring products are suitable for medical class 2 and class 1 places and other places that
need to monitor the residual current, mainly used for monitoring the residual current of TN-S distribution system
mains and branches. When the residual current value exceeds the preset threshold, the system will send an alarm
signal to remind the staff to deal with it according to the actual situation, so as to eliminate the potential safety
hazards such as electrical fire and electric leakage shock caused by the residual current and provide clean, safe and
continuous power supply for the equipment. The residual current monitoring products are also the monitoring
instruments developed by Acrel with rich product design experience and strict reference to the requirements in the
standards and specifications. The product conforms to the enterprise standard Q31/0114000129C025-2017

5.2 Method of installation
In addition to the AID150 centralized alarm and display instrument, the residual current monitoring products
are best centrally installed in the distribution cabinet. AIM-R100 residual current monitor uses 35mm standard
guide rail to install, AKH-0.66/L-20 residual current transformer uses screws (attached) directly fixed installation.
When the AID150 centralized alarm and display instrument is used in the operating room, it can be embedded in
the wall and installed next to the information panel in the operating room for medical personnel to view; When
AID150 is used in other medical places, it is recommended to install in the nurse station. It can also be installed in
other locations that are easy to monitor. External wiring of the AID150 centralized alarm and display instrument
includes two DC24V power supply lines and two RS485 communication lines, which are drawn from the
distribution cabinet. Pipelines should be reserved during construction. In the centralized monitoring, the RS485
communication between the AIM-R100 and AID150 should be connected hand in hand.
5.2.1 Installation method of AIM-R100 residual current monitor
The AIM-R100 residual current monitor is installed with guide rail and fixed with buckles, as shown in the

5.4 Typical wiring method
Description:
(1) Each residual current monitor can be equipped with at most 12 AKH-0.66/L-20 residual current
transformers.
(2) Terminals 1 and 2 of the AIM-R100 residual current monitor and terminals 1 and 2 of the power supply
of ACLP10-24 DC24V power supply shall be connected to AC220V, which can be directly connected to the bus
bar as shown in the figure above, and connected to fuse protection of 6A.
(3) Terminals 13 and 14 of the AIM-R100 residual current monitor are connected to the remote reset button,
which is used for the automatic reset of the instrument to ensure the safety and reliability of the system.
(4) When applied to single-phase branches, AKH 0.66/L-20 needs to pass through two lines of L and N of
each output circuit, and the PE line does not need to be worn in; When applied in three-phase three-wire branch,
the transformer passes through three wires A, B and C. When applied to three-phase four-wire, the transformer

passes through four wires A, B, C and N. Residual current transformer output lines connected to the
corresponding terminal of AIM-R100, connecting to 100Ω resistance to empty terminal to avoid causing false
alarms.
(5) terminal 15, 16 of the AIM-R100 residual current monitor and Terminals A and B of AID150 centralized
alarm and display instrument can be connected with 2x1.5 mm2 shielded twisted-pair cable. When AID150
centralized alarm and display is used to monitor multiple AIM - R100, the connection mode of the communication
line should be hand in hand (A to A, B to B, one by one), RS485 bus between the end of the first two
communication terminal should be matches with a resistance, recommend and appendant resistance is 120 Ω.
5.5 Matters needing attention
(1) The residual current monitoring products, except for the AID150 centralized alarm and display
instrument, should be centrally installed in the isolated power cabinet or distribution cabinet. centralized alarm
and display instrument generally select wall installation.
(2) During installation and wiring, the wiring diagram shall be strictly followed. It is better to press and
connect the wiring with the needle-type sleeve joint, then insert the corresponding terminals of the instrument and
tighten the screws to avoid abnormal working of the instrument due to poor contact.
(3) the empty loop of AIM-R100 must be connected to 100Ω resistance, avoid the break line fault alarm.

7 Communication Protocol
7.1 Communication protocol introduction
The device uses Modbus-RTU communication protocol, which defines check codes and data sequences in
detail, all of which are necessary for specific data exchange. The Modbus protocol uses a master-slave responder
connection (half duplex) on a single communication line, which means that signals are transmitted in opposite
directions on a single communication line. First, the signal of the master computer is addressed to a unique
terminal (slave), and then the reply signal from the terminal device is transmitted to the host in the opposite
direction.
Modbus protocol only allows communication between the host computer (PC, PLC, etc.) and terminal

equipment will not occupy the communication line when they are initialized, but only respond to the query signal
arriving at the machine.
7.2 Introduction to function code
7.2.1 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.

7.2.2 Function code 10H: write register
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.
