INTRODUCTION
QSI
The QSI communications module is a multiple capability electronics package and
has three versions (QSI1, QSI2 or QSI3) available; each with its own mix of
capabilities to better serve the customer (See Versions below).
The module is also available as a “display ready” version with no display installed,
but ready for the customer to install their own GPI “09” display.
•
QSI1:
Equipped with Bluetooth®, coil/digital pulse input, pulse output (flow
or energy & scalable), RS485 (Modbus® RTU), temperature inputs, BTU
calculator.
•
QSI2:
Equipped with Bluetooth, coil/digital pulse input, pulse output (flow
or energy & scalable), temperature inputs, BTU calculator.
•
QSI3:
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
QSI electronics are available factory installed on designated meters, or as modules
that will adapt the electronics to other FLOMEC meters.
The QSI electronics converts the voltage (or pulses) from the meter into usable
information to support the various capabilities of the modules. The modules also
supply the display (when installed on display ready versions) with the information
and power it needs to function as designed.
The QSI module electronics are powered by customer- supplied external power.
SAFETY
