INTRODUCTION
The QSI communications
module is a multiple capability
electronics package. The module
is available with the plain cover
plate or the display mount cover
plate. 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 (ow or
energy & scalable), RS485
(Modbus® RTU), temperature
inputs, BTU calculator.
• QSI2 is equipped with:
Bluetooth, **coil/digital
pulse input, pulse output
(ow or energy & scalable),
data logger, temperature
inputs, BTU calculator.
• QSI3 is equipped with:
Bluetooth, **coil/digital pulse
input, pulse output (ow scalable),
data logger, 4-20mA output.
**NOTE The coil/digital input
connections are for use with
equipment other than a QSE meter.
QSE meters automatically provide
coil/digital pulse input via the 10-pin
ribbon cable from the AFE PC board.
If the QSI electronics are used
in a manner not specied by the
manufacturer, the protection provided
by the equipment may be impaired.
GENERAL INFORMATION
QSI electronics are available
mounted to the meter you
ordered or as a kit that adapts the
electronics to other GPI meters.
The QSI electronics converts
the voltage (or pulses) from the
meter into usable information. In
addition to the multiple capabilities
of the module, it also supplies
the display (when installed) with
the information and power it
needs to function as designed.
The QSI module electronics
is powered by customersupplied 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
specications in this manual.
• Disconnect external power
before attaching or detaching
input or output wires.
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.

INSTALLATION
CAUTION: Installation near
high electromagnetic elds
and high current elds is not
recommended and may result
in inaccurate readings.
If you ordered your QSI module
electronics with a QSE meter, it
is installed at the factory. If you
ordered your QSI module electronics
separately (i.e. repair part), follow
the instructions below to install
on a QSE meter. If you ordered
your QSI module with one of our
several types of meter adapter kits,
follow the separate instructions
enclosed with the kit to install
the unit. In every case, please
review and thoroughly understand
all manuals and installation
instructions before proceeding.
To mount your QSI module (with or
without a display) to a QSE meter:
• Install the cover plate seal.
• Connect the QSI module PC
board connector to the AFE
module PC board connector
inside the meter housing with
the ribbon cable. The ribbon
cable connectors are polarized
and cannot be incorrectly
connected (see Figure 1).
• Install the cover plate with
screw holes aligned.
• Install the (6) cover plate screws
and tighten. Make sure the
cover plate seal is fully seated
before tightening the screws.
A ribbon cable connects the
QSI electronics within the cover
plate to the AFE electronics
within the meter body and allows
180 degrees of movement in
either direction (see Figure 2).

WIRING
All electronic options are associated
with a matching 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 ttings 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 ttings
that t your process and replace
the threaded plugs in the cover
plate with the ttings as required.
The threaded plugs installed at the
factory may be left in any unused
cover plate port indenitely.

It is recommended that a “removable”
thread-locker (uid, 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 ttings are used
for attaching ex conduit to the meter,
for those applications that require
cable runs to be enclosed in conduit.
• Cable to be provided by
customer to accommodate
job requirements. Cable is
not included with meter.
