INTRODUCTION
The QSI communications module is a multiple capability electronics package. For
the G2 meter, the module is available with the plain cover plate only. The QSI
module has three versions (QSI1, QSI2 or QSI3) available; each with its own mix
of capabilities to better serve the customer (See Versions below).
•
QSI1 is equipped with Bluetooth®, coil/digital pulse input, pulse output (flow or
energy & scalable), RS485 (Modbus® RTU), temperature inputs, BTU
calculator.
•
QSI2 is equipped with Bluetooth, coil/digital pulse input, pulse output (flow or
energy & scalable), temperature inputs, BTU calculator.
•
QSI3 is equipped with Bluetooth, coil/digital pulse input, pulse output (flow
scalable), 4-20mA output.
This manual contains information and meter wiring diagrams for the three different
QSI electronics modules.
IMPORTANT NOTICE
QSI module electronics are very sensitive to electric noise if operated within 6
inches of some electric motors, relays, transformers or other sources of electronic
noise.
If the QSI electronics are used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
GENERAL INFORMATION
