Functional Description

The Allegro Cellular PIT_Unit X module is a battery endpoint for the application of automatic water meter reading. The primary function of the module is to record consumption of a water meter from an Encoder register.
The Allegro unit stores the meter reading in an internal log and pushes the data via the radio on a daily basis.

The standard working mode transmits daily 24-hourly meter reads, which include high-level detailed information like Consumption, Flow, Meter Alarms …

Installation

Remove the PIT lid, Figure 3.
Install the PIT booster Module into the Pit Lid, Figure 4.

Connect PIT_Unit X module cable to the water meter inside the Pit-Set, make sure both arrows are located in front of each other and tightly together, Figure 5.

Pay attention!
PIT_Unit X module may come with a variety of cables, plugs. In case of bare wire, connect the wires according to the Meter manufacturer’s guidance

Place a magnet on the PIT_Unit X module bottoms as illustrated

The LED will indicate (Figure 6) the process as described below.
When the magnet is sensed LED blinks several times slowly.
When the LED starts to blink fast (~after 10 seconds) magnet should be removed.

After the PIT Booster Module is magnet activated, it will automatically be ready to transmit based on the production schedule configuration.
Close the Pit Lid

FCC STATEMENT

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 a minimum separation distance of at least 20 cm from all persons and must not be colocated 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, under 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 following the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in an 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 to 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 chosen so 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.
Cet appareil numerique de la classe B est conforme a la norme NMB-003 du Canada.
