Allegro IOT Interpreter LR9 Module

CAUTION
This device complies with part 15 of the FCC Rules. The User and the Installer should be aware that changes and modifications to the equipment not expressly approved by Master Meter could void warranty and the user’s authority to operate the equipment.
Professionally trained personnel should install the equipment.
The antenna used for this transmitter must be installed to normally provide minimum separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
ATTENTION
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

Industry Canada (IC) Compliance Notice
This device complies with FCC Rules Part 15 and with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent Isotropically radiated power (EIRP) is not more than that necessary for successful communication.

This Class B digital apparatus complies with Canadian ICES-003.

Functional Description

The Allegro IOT Interpreter LR9 Module is battery endpoint for the application of automatic water meter reading. The primary function of the module is to measure consumption of FAM water meter.
All processed data is sent via built-in radio.
Several operational modes are available based on production configuration, standard mode transmits four times a day 24-hourly meter reads.

Installation

Install the FAM Flow Tube with Plug in the line, make sure the arrow on the Flow tube is pointing in the direction of water flow, Figure 3.
When installing the FAM Flow Tube with Plug, be sure to vertically level the Plug for future replacement with FAM Measuring Unit. Turn tap on to release any trapped air in line to the house/apartment. After air is released spot check for leaks around the installation, Figure 4.
Install the FAM Tube with Measuring Unit in the line; make sure the arrow on the Flow tube is pointing in the direction of water flow. Before completely tightening the couplings or soldering, make sure the Measuring unit is vertically level, Figure 5.
After Installing and leveling the meter vertically, check to see if the Measuring unit is level horizontally. Level the Measuring Unit by loosening the locking nut clockwise, adjusting the Measuring Unit and tighten nut counter clockwise, Figure 6.
Loosen the Locking Nut with FAM wrench and take plug out Figure 7.
Replace both O-rings that are in the Flow Tube with new ones that were shipped with the FAM measuring Units. Apply a little lubricant on o-rings during this procedure, Figure 8.
Position FAM Measuring Unit to Flow Tube; be sure the Measuring Unit is seated properly when mated with Flow Tube and that it is vertically level, Figure 9.
Hand-tighten Locking Nut by keeping the Measuring Unit vertically in position, Figure 10.
Tighten Locking Nut with FAM wrench until snug; do not over tighten. For leveling with level refer to F1 and F2, Figure 11.
Allegro IOT Interpreter LR9 register should be in Storage mode indicated by “Stor” display on LCD, see Figure 12.
Attach magnet to register (6 O’clock, Figure 13) for 17 seconds then remove magnet to activate Allegro IOT Interpreter LR9 register.
Unit is now activated and trying to join LoRaWAN network automatically, joining process is indicated with “J”, Figure 14.
