Prelude
This guide describes the functionalities of the products of the ATIM ACW-MR range. It explains the operating,
configuration, and installation modes of the products according to the different use cases.
ACW-MR product line
The ACW-MR range includes several types of radio equipment for pulse counting, change of state detection and fraud
detection, each intended for different uses.
All products in the range are available in LoRaWAN and Sigfox versions and are delivered with removable batteries.
They are configurable via internal switches and by sending Downlink messages from the network (only in LoRaWAN
version).
ACW-MR1
The ACW-MR1 is a device used for the remote reading of meters (gas, water, electricity, rain gauge...)
or for the remote detection of equipment status changes (e.g.: start/stop of equipment, opening/closing
of a door, a skydome, etc...).
For remote meter reading (Smart Metering), the ACW-MR1 must be connected to a pulse meter. If your
meter is not equipped with pulse outputs, many compatible pulse headers are available on the market.
In addition to its counting input, the ACW-MR1 is equipped with a dry contact input allowing to trigger
transmissions in case of change of state. This input can be used as a fraud detection in case of cable
cut.
The ACW-MR1 comes with a pack of 2 removable Lithium Ion 3.6V batteries, with a total capacity of
7.2Ah.
CAPT-OPTO
An optical head accessory is available for the ACW-MR1:
-a light guide to be clipped with a suction cup on any
electrical equipment equipped with an LED.

Installation of the OPTO cable
a. Description of pieces
b. Procedure
Fix the washer (F) on the location where the survey is to be carried out, so that the light
signal passes through the middle in the hole. It is important to clean the area and dry it to
ensure a reliable grip in the long term.
Position the part (E) on the washer so that the light signal is visible through the hole that
goes right through it. Alignment is essential.
Mount the cable (C) in the MR1 housing (A), lock the assembly by tightening the nut (B).
Finally, pass the clamping sleeve over the cable (C), place the other end of the cable at the bottom of the sleeve (E)
and clip parts (D) & (E) together to exert strong pressure against the adhesive washer (F).

ATIM_ACW-MR1_UG_EN_V1.6
Operation
a. Input 1: pulse counter
The ACW-MR1 has a metering input that can be connected to a dry contact or open collector type pulse emitter for
remote meter reading, and a dry contact input indicating an ON/OFF status.
Two modes of use are proposed:
1. Standard Meter reading
The sensor increments an index with each received pulse. Periodically (e.g. once an hour or once a day), it
transmits the index to the radio network.
2. Eco Meter Reading
The sensor increments an index with each received pulse. Periodically (for example every 10 minutes), it
memorizes the value of the index. When it has stored 6 values, it transmits them in a single frame to the radio
network.
NOTE
The index value is regularly saved in non-volatile memory to not being lost in case of power loss (for example when batteries
are empty). However, when a power loss is happening, the pulses received during the previous 10 minutes may be lost (in
addition to the pulses received during the power loss).
b. Output copy of the pulse in Mirror mode
The ACW-MR1 is equipped with an output to copy the pulse input. This makes it possible to be easily inserted
in an existing installation where there is already a pulse transmitter. In this case, the ACW-MR1 is inserted between
the meter and the pulse emitter.
The output terminals are called OUT1- and OUT1+ (galvanically isolated MOSFET dry contact).
c. Input 2: dry contact –detection of change of state
This input can be connected to a dry contact for change of state detection, in on-off mode. By default, if the sensor
detects a change of state on this input, it transmits an alert frame.
d. Input Optical head
The card is equipped with a phototransistor that detects the light pulses from the optical fiber if it is connected to
the cable gland (ACW-MR1/OPTO mode).
