INTRODUCTION

GENERAL INFORMATION

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® RDU), 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.

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
specications 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 1/2-20 UNF threaded ports,
compatible with PG7 threads, for
wiring access to the electronics inside
the cover plate. The meter is shipped
with the ports environmentally
sealed with PG7 threaded strain
reliefs tted with mushroom plugs.
The mushroom plugs are inserted
into the cable glands of the strain
reliefs to maintain the seal until
the port is used for wiring. Strain
reliefs with mushroom plugs can be

4

left in any unused port indenitely.
Remove the mushroom plugs to
run cable into the cover plates.

The strain reliefs will accommodate
a cable diameter of 0.11 - 0.26
inches (2.79 - 6.6mm) and provides
an environmental seal around
the cable when tightened.

• Cable to be provided by
customer to accommodate
job requirements. Cable is
not included with meter
