UNPACKING/INSPECTION
Inspect
•
After unpacking the unit, inspect carefully for any damage that may
have occurred during transit. Check for loose, missing or damaged
parts. Shipping damage claims must be filed withcarrier.
•
See General Safety Instructions, and all Cautions, Warnings, and
Dangers as shown.
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
QSI electronics are mounted into the cover plate of the meter you ordered. The
QSI electronics converts the voltage (or pulses) from the meter into usable
information.
The QSI module electronics is powered by customer supplied external power.
SAFETY
•This product is not approved for use in hazardous locations.
•Be sure O-rings and seals are kept in good repair.
•When applying power, adhere to specifications in this manual.
•Disconnect external power before attaching or detaching input or output wires.

INSTALLATION
CAUTION: Installation near high electromagnetic fields and high current fields is
not recommended and may result in inaccurate readings.
NOTE: There is no external visual difference between QSI1, QSI2, or QSI3
communications suites when they are installed.
NOTE: If you ordered a QSI communications suite with your meter, it was installed
at the factory. Please review and thoroughly understand all manuals and
installation instructions before proceeding.
WIRING
All electronic options are associated with a flat style of meter cover plate. This
cover plate has four threaded ports, compatible with PG7 threads, for gaining
wiring access to the electronics inside the cover plate.
The meter is shipped with the ports environmentally sealed with a threaded plug
and seal. Remove one or more of these plugs as required to install the supplied
port fittings below.
Each meter is supplied with cable gland strain reliefs with O-rings and 1/2 NPT
adapters with seals for use in the threaded ports of the meter cover plate.
Select the port fittings that fit your process and replace the threaded plugs in the
cover plate with the fittings as required.
NOTE: The threaded plugs installed at the factory may be left in any unused cover
plate port indefinitely.
It is recommended that a “removable” thread-locker (fluid, stick, tape, spray, etc.)
be used when installing the strain reliefs or adapters into the cover plate ports.
STRAIN RELIEFS
The cable gland strain reliefs will accommodate a cable diameter of 0.11 - 0.26
inches (2.79 - 6.6mm) and provide an environmental seal around the cable when
the dome-nut is tightened.
NPT ADAPTERS
The 1/2 NPT adapter fittings are used for attaching flex conduit to the meter, for
those applications that require cable runs to be enclosed in conduit.
NOTE: Cable to be provided by customer to accommodate job requirements.
Cable is not included with meter.
