MTU Wiring
•
General - Many MTUs connect to the
meter by means of a 3-conductor, 22gauge solid conductor wire. The wire is
housed in a PVC jacket with UV
inhibitors. A black-jacketed wire is
supplied on single-port MTUs and for port
1 of dual-port MTUs. A grey jacket is
used for the port two input to dual port
MTUs.

Wire Length – MTUs are provided with a
standard wire length of 12 feet. Additional
wire may be used if necessary. A
maximum run of up to 500 feet can be
used to position the MTU in a favorable
location. Use like-colors for cable jackets
and individual wires when extending MTU
wiring.
Some specific meters may impose other
wire length limitations. Consult the meter
manufacturer.
Wire Routing - Wires should be attached
to walls with 9/16” staples. If wire
clearance holes are needed to route wire
from the meter to the MTU, drill a ¼” hole
using an appropriate drill bit. The installer
is responsible for the selection of an
appropriate location for any hole to be
drilled.
Note: Wiring must be in accordance with
all national and local codes.
Wire Protection - A drip loop below the
MTU is not required.
Inspect wire to ensure that routing and
stapling have not caused wire damage.
Pull the wire lightly at each staple to
make sure that the staple is not set too
tightly.
Any splices made to wire must be
suitable for the environment and made in
accordance with national and local codes.
Page 5
MTU Instructions
General Installation and Wiring Guidelines
They must be secure and made in
accordance with the connection supplier’s
instructions. Generally, gel-filled
Insulation Displacement Connectors
(IDCs) such as 3M ScotchLok or AMP
Tel-Splice connectors should be used on
all wire-to-wire connections.
Since MTU transmissions are similar in
nature to cellular phone signals, a cellular
phone can be used to help to determine if
a location is suitable for MTU mounting.
If the cellular phone signal drops
dramatically or indicates no signal at the
desired location, it is possible that the
MTU signal will also be blocked at this
location. In this case, the MTU will have
to be mounted in a different location,
possibly on the outside of the structure.
Keep the MTU away from all other
electrical wires.
Note: Do not mount the MTU under
wiring such as Romex, AC power wires,
cable TV wire, or telephone wire. Do not
allow these wires to lay on top of, or in
front of the MTU.
Splices located outdoors or in meter pits
should be further protected through the
use of a direct burial kit. This consists of
a gel-filled plastic tube that houses the
individual wire-to-wire splices to provide
additional protection from the elements.
Note: Keep the MTU six inches away
from metal items such as pipes, conduit,
electric meters, electrical boxes, and
downspouts.
Make sure screws used to mount the
MTU do not protrude and pierce or
otherwise damage any wires, cables, or
pipes.
MTU Positioning and
Mounting
General - MTUs must be positioned and
mounted properly to ensure optimum RF
signal propagation. Each MTU contains
an internal antenna near the top front
surface of the sealed enclosure. As a
result, the MTU should always be
mounted vertically and the STAR logo
should face the installer.
Page 6
Use of Spacer – There are two primary
styles of MTUs. The Original Flatpak
STAR MTU requires the use of a spacer
(Hexagram Part Number 056-5155H1)
when the MTU is mounted on any surface
other than wood. The NEW Flatpak
STAR MTU is a modified design that can
be directly mounted to a variety of
surfaces without the use of a spacer.
See the examples below for additional
information.
MTU Instructions
General Installation and Wiring Guidelines
NEW Flatpak STAR MTU – An example
of the NEW Flatpak STAR MTU is shown
below. These MTUs are approximately
6.5” x 4.25” x 1.5” thick, and can be
mounted on most surfaces without the
use of a spacer.
Original Flatpak STAR MTU – An
example of an Original Flatpak STAR
MTU is shown below. These MTUs are
6.5” x 5.5” X 1” thick, and require a
spacer if mounted on any material other
than wood.
Note: Do not use a spacer when
mounting an Original Flatpak STAR MTU
on wood.
Page 7
MTU Instructions
General Installation and Wiring Guidelines
Outdoor Mounting
MTUs mounted outdoors are typically
mounted to the side of buildings, to a
stationery post, to the piping surrounding
the meter, or to a pit lid.
Mounting to a Buiding or Post
If the unit is being mounted to the outside
of a building, the MTU will be connected
to wires that lead from the inside to the
outside of the building. If existing wire is
used, it must be of the same quality as
specified in MTU Wiring. It must also be
in good condition, without breaks,
damage, or corrosion.
Step 1 – Select a mounting location for
the MTU that will allow optimum signal
transmission.
Step 2 – Run wiring from the MTU to the
meter. If a splice is required, it may be
placed inside or outside. For special
circumstances, contact your supervisor.
If using existing wiring, remove any box
that houses the outside wires.
Step 3 – Mount the MTU on the side of
the building.
•
The MTU must be mounted
level, vertically with the STAR
logo facing the installer. Allow a
1” space between the top of the
MTU and the overhang of the
siding above it. This is critical
for proper radio signal
transmission.
•
Use a Spacer (Hexagram Part
Number 056-5155H1) if
mounting an Original Flatpak
STAR MTU on a non-wood
surface.
Page 8
CAUTION!
Do not over tighten screws.
Excessive torque will crack
the MTU enclosure. Do not
tighten screws beyond the
point that the MTU touches
the mounting surface.
Step 4 – Make the appropriate
connections to the meter. Refer to the
specific MTU Instruction for the meter in
use.
Bar or Pipe Mounting
Particularly in outdoor gas applications, it
is sometimes convemient to mount the
MTU to the connecting piping. With the
Original Flatpak STAR MTU this is easily
done using a bar-mount spacer and two
18” long tie-wraps, (See Recommended
Supplies.)
Step 1 - Thread the tie-wraps into the bar
mount spacer as shown here.
MTU Instructions
General Installation and Wiring Guidelines
Step 2 - Attach the spacer to the MTU
using #10-32 stainless steel screws, nuts
and washers. Tighten the screws to 12 to
15 in-lb. On a standard drill driver with 0
to 24 torque settings, this is typically the
#10 setting.
Pit-Lid Mounting
For water or gas meters located in meter
pits, MTUs can be mounted to the lower
surface of the pit lid if an approved, nonmetallic pit lid is used. In these
applications, the MTU is mounted with it’s
front surface facing the bottom surface of
the lid, as shown below
Original Flatpak STAR MTU
Step 3 - Wrap the tie wraps around the
bar as needed, pulling the ties around
(through the spacer plate) as they are
tightened.
Step 4 - Adjust the MTU as needed and
pull the tie wraps tight.
When NEW Flatpak STAR MTUs are
mounted in this manner, spacers are
used between the MTU mounting tabs
and the lower surface of the pit lid, as
shown below.
Revised Flatpak STAR MTU
Step 5 - Trim off the excess tie wrap,
leaving about a ½” tab.
Step 6 – Once Installation is complete,
program the MTU using the STAR
Programmer Software and your MTU
Programmer.
Page 9
MTU Instructions
General Installation and Wiring Guidelines
A long spacer is available, for use when
the lower surface of the pit lid is a flat,
solid surface. A short spacer is used
when the lower surface of the pit lid in
use has a ribbed construction.
Do not mount the MTU if large metal
objects, such as heating ducts, block both
the front and rear of the MTU. If
absolutely necessary, a single large metal
object may be located several feet away
from the MTU.
Unfinished Basement
Step 1 – Select a mounting location for
the MTU that will allow optimum signal
transmission. In unfinished basements,
this is typically high on a ceiling joist, at
least a few inches away from outside
walls.
Contact Hexagram for information on
approved non-metallic pit-lids.
Indoor Mounting
For an inside mount, mount the MTU
vertically on a ceiling joist. It is important
to mount the MTU as high as possible.
Note: The MTU must be mounted above
grade.
Because the outside wall of a building
can have metal siding or foil insulation,
keep the MTU a few inches away from
the outside wall. Transmissions easily
pass through wood and masonry.
Do not install an MTU inside if the
basement has a metal ceiling or foil-lined
insulation in the ceiling or if it has foil on
the sidewalls running from grade to
ceiling. This will prevent the signal from
transmitting effectively.
Large metal objects such as heating
ducts, steel cabinets or metal ceiling
structures can block MTU transmissions.
Select locations that are at least five to
ten feet away from objects such as these.
Page 10
Step 2 – Mount the MTU.
• The MTU must be mounted
level, vertically with the STAR
logo facing the installer. Allow a
1” space between the top of the
MTU and any overhang above
it. This is critical for proper
radio signal transmission.
• Use a Spacer (Hexagram Part
Number 056-5155H1) if
mounting an Original Flatpak
STAR MTU on a non-wood
surface.
CAUTION!
Do not over tighten screws.
Excessive torque will crack
the MTU enclosure. Do not
tighten screws beyond the
point that the MTU touches
the mounting surface.
MTU Instructions
General Installation and Wiring Guidelines
Step 3 – Run wiring from the MTU to the
meter. Carefully staple the wire to the
wall every 18” and at every change in
direction using 9/16” staples. All turns
are to be at right angles. If wire must be
run on masonry, secure it with wire clips.
Run wires parallel to the joist. If a joist
must be crossed, run at a 90 degree
angle. If the MTU input cable must be
extended, use an appropriate splice.
Make sure inner conductors are not
nicked during stripping.
Step 4 – Make the appropriate
connections to the meter. Refer to the
specific MTU Instruction for the meter in
use.
Finished Basement
Step 1 – Select a mounting location for
the MTU that will allow optimum signal
transmission. In Finished basements,
this may be high on a ceiling joist in an
unfinished section of the basement or
high on an interior wall near a window or
outside wall, but at least a few inches
away from outside walls.
CAUTION!
Do not over tighten screws.
Excessive torque will crack
the MTU enclosure. Do not
tighten screws beyond the
point that the MTU touches
the mounting surface.
Step 3 - Run wiring from the MTU to the
meter. Run all wiring behind the wall if
possible. Carefully staple the wire to the
wall every 18” and at every change in
direction using 9/16” staples. All turns are
to be at right angles. If wire must be run
on masonry, secure it with wire clips. Run
wires parallel to the joist. If a joist must be
crossed, run at a 90 degree angle. If the
MTU input cable must be extended, use
an appropriate splice. Make sure inner
conductors are not nicked during
stripping.
Step 4 – Make the appropriate
connections to the meter. Refer to the
specific MTU Instruction for the meter in
use.
Note: Ceilings may contain metal.
Therefore, the MTU should be placed 2 to
3 inches down from a plaster or ‘dropped’
ceiling.
Step 2 – Mount the MTU.
• The MTU must be mounted
level, vertically with the STAR
logo facing the installer. Allow a
1” space between the top of the
MTU and any overhang above
it. This is critical for proper
radio signal transmission.
• Use a Spacer (Hexagram Part
Number 056-5155H1) if
mounting an Original Flatpak
STAR MTU on a non-wood
surface.

MTU Instruction
for Rockwell/Equimeter/Sensus Gas Meters
Tools Required
To mount the MTU to these meters, you
will need the following tools and
equipment:
•
•
•
•
•
Step 4 – Turn the MTU over and insure
that there is a pre-applied gasket on the
back of the MTU as shown below.
Cordless drill ⅜”, variable
speed, with adjustable torque
settings
#2 Phillips bit
Safety goggles
Phillips screwdriver
Slotted screwdriver
Installation Procedure
Before installing the MTU, anti-tamper,
safety, and security hardware must be
removed from the clear register cover.
Step 1 - Remove the existing clear
register cover by removing the four
screws. Discard the screws and cover.
Step 2 - Remove the register by
removing the two screws. Set the register
aside. Discard the screws.
Step 3 - Insert the four 10-24 x 1⅛”
screws through the holes on the MTU as
shown.
Note: Couplers are pre-assembled to the
MTU. Insure that the couplers are firmly
attached to the shaft and that the coupler
on the front side of the MTU contains the
magnet. Also, verify that the plastic
washer is in place between the rear
coupler and the MTU.
Step 5 - Position the MTU on the meter.
Rotate the coupler so that the gear tooth
on the coupler engages with the gear
teeth on the gas meter. Orientation is not
critical, but you should be able to feel the
teeth “bite” when you turn the coupler
from the front of the MTU.
Step 6 - Tighten the four 10-24 x 1-⅛”
screws to 12 to 15 in-lb. On a standard
drill driver with 0 to 24 torque settings,
this is typically the #10 setting. Tighten
corner to corner.
Step 7 - Check the coupler. It should
have slight play — it should not bind or
turn too freely.
Page 16
MTU Instruction
for Rockwell/Equimeter/Sensus Gas Meters
Step 8 – Select gear to fit between the
register and the MTU without binding.
Typically, the correct gear can be
selected based upon the type of index in
use, as shown in the following table.

below. Hand tighten to a torque not to
exceed 3-5 inch-pounds. Make sure the
index register gear and the MTU coupler
gear are engaged.
Place the selected gear into the coupling.
The head of the pin on the gear needs to
be facing out.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Power tools are not
recommended for use on
steps 9-12.

MTU Instruction
for Rockwell/Equimeter/Sensus Gas Meters
Step 11 - After you feel engagement
between the index register gear and the
MTU coupler gear, tighten the register
screws until they are snug.
Step 12 - Place the new cover over the
register so that the top label or arrow is
on top and the vent holes are on the
bottom. Align the cover with the mounting
holes on the MTU, press it into place, and
insert the #10 x 1” screws. Hand tighten
to a torque not to exceed 3-5 inchpounds. The gasket should be
compressed slightly.

MTU Instruction
for American Meter Company Gas Meters
Tools Required
To mount the MTU to these meters, you
will need the following tools and
equipment:
• Safety glasses
• Phillips screwdriver
• Slotted screwdriver
Installation Procedure
Before installing the MTU, all anti-tamper,
safety, and security hardware must be
removed from the clear register cover.
Step 1 - Remove the existing clear
register cover by removing the four
screws that hold it. Discard both the
screws and the cover.
Step 2 - Remove the register by
removing the two screws that hold it. Set
the register aside. Discard the screws.
Step 3 - Mount the register onto the MTU,
fastening the register to the mounting
holes shown here with the #8 x 3/8”
screws provided.
Start one of the two screws into the
mounting hole, and then slide the register
beneath the screw aligning the wiggler on
the register with the MTU coupler.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Use of Power tools is not
recommended.
Page 26
Then insert the second screw and tighten
both screws to a torque not to exceed 3-5
inch-pounds.
Note: On some odometer-style registers
like the one shown below, slight
protrusions on the back of the register
assembly can interfere with proper
alignment of the register. Should this
occur, use a diagonal cutting plier to trim
the two wire guides on the MTU to the
right of the coupler. Trim these guides as
close to flush with the MTU enclosure as
possible. (See MTU photo below.)
MTU Instruction
for American Meter Company Gas Meters
Step 4 – Check that the register is
properly engaged by rotating the coupler
on the back of the MTU and observing
the register dials.
Step 5 – Next, Insert the two ¼-20 x 1
1/4” machine screws through the holes on
the MTU as shown here.

may damage the MTU enclosure.
Because of this, power tools are not
recommended for this procedure.
Step 6– Turn the MTU over and place the
gasket on the back of the MTU so that it
aligns over the two screws.
Step 9 - Check the coupling one more
time. It should have slight play — it
should not bind or turn too freely.
Step 7 – Next, position the MTU on the
meter. Tighten the two ¼-20 x 1 1/4”
mounting screws most of the way, and
then rotate the register dials slightly to
engage the wiggler on the gas meter. The
wiggler must engage with the rear coupler
on the MTU as shown in these
illustrations. (Coupler shown detached
from the MTU for illustration purposes
only.)
Step 10 - Place the new cover over the
register so that the top label or arrow is

Introduction
STAR Submetering MTUs with Pulse
Adapters provide accurate, highresolution data for point-of-use allocation
billing for a wide variety of HVAC
appliances.
Note: Only on-off devices are suitable for
application of these pulse adapter MTUs.
•
Voltage Sensing Pulse
Adapters can be applied to
gas appliances that are
controlled by a standard
24VAC gas valve.
• Temperature Sensing Pulse
Adapters can be applied to
gas water heaters, fireplaces
and other HVAC appliances
that do not have 24 VAC
controls
These units produce an extremely
accurate pulse at a rate of 10 seconds
per pulse (0.1 Hz or 6 pulses per minute)
when the specified input conditions
(voltage or temperature) are met. These
pulses are counted by the MTU which
periodically transmits the accumulated
count to nearby Data Collector Units.
Note: The submetering MTUs discussed
in this instruction are for indoor use (dry
locations) only.
Page 44
Connecting Voltage Sensing
(Type P) Inputs
Voltage Sensing (Type P) inputs are
provided with a 2-wire connection that
can be wired across (in parallel with) the
24 VAC gas valve solenoid of the furnace
or other HVAC appliance.
Simply connect the RED and BLACK
wires across the gas valve solenoid.
Once connected in this way, a voltage of
between 18 and 30 VAC applied across
the valve solenoid will cause the MTU to
begin pulsing and recording usage.
CAUTION
Do not connect the white wire
of the MTU when connecting
voltage sensing inputs. Cut
the white wire back to the
cable jacket. Connecting the
white wire may damage the
MTU.
Typical Furnace Application
This procedure covers a typical
installation of a voltage/current sensing
pulse adapter on a gas furnace.
Step 1 - Turn the furnace setting to "Pilot"
so that it will not operate during the
installation process.
Step 2 - Mount the MTU on a wall, joist or
other convenient location near the
furnace to be monitored. Run the cable
from the MTU to the gas valve solenoid of
the device. Trim or extend the MTU
cable, as needed. Care must be taken to
protect the cable from damage by hot
surfaces or sharp sheet metal. Use
insulated staples or cable ties as needed.
Note: Be sure to follow all General
Mounting & Wiring Guidelines outlined in
Publication 471-2000.
MTU Instruction
for STAR Submetering MTUs with Pulse Adapters
Step 3 – Connect the RED and BLACK
leads from the MTU across (in parallel
with) the 24 VAC control input to the gas
valve. On most gas valves, these
connections can be made at the terminals
on the gas valve solenoid.
Step 4 – Program the MTU using the
MTU Programmer as outlined in the
Programming section of this document.
Step 5 - Return the furnace setting to
"Run".
Connecting Temperature
Sensing (Type T) Inputs
Temperature Sensing (Type T) inputs are
provided with a two wire connection
designed to be directly connected to a
Type E thermocouple that is supplied with
the temperature sensing MTU. When the
thermocouple reaches a temperature of
110◦ - 130◦ C (230◦ - 265◦ F), the MTU will
begin pulsing and recording usage.
● The VIOLET lead is the positive
side and must be connected to the
RED wire of the MTU Input Cable.
● The RED lead of the thermocouple
is the negative side and must be
connected to the BLACK wire of
the MTU input cable.
Typical Hot Water Heater
Application
This procedure covers a typical
installation of a temperature sensing
pulse adapter on a gas hot water heater.
Step 1 - Turn the hot water heater setting
to "Pilot" so that the heater will not
operate during the installation process.
Step 2 - Insert the copper thermocouple
sleeve into the space under the draftinducer cone at the top of the water
heater. Position the tip of the
thermocouple INTO the center of the flue
as shown below. ( ½ to ¾ of an inch)
By convention, Type E thermocouples are
supplied with two color-coded leads.
Page 45
MTU Instruction
for STAR Submetering MTUs with Pulse Adapters
Gently shape the copper sleeve on the
thermocouple so that it does not contact
the metal surface of the draft hood or the
top of the hot water tank as shown in the
side view illustration.
Step 3 - Clean the surface area of the hot
water heater under the thermocouple.
Dry thoroughly. Locate and mount the
two pressure sensitive hold-downs in the
cleaned area. Locate one hold-down at
the approximate center of the copper
sleeve and the other at the very end so
that they firmly anchor the thermocouple.
Thread a cable tie through the slot in the
hold-downs to fasten the thermocouple.
If necessary, gently form the copper
sleeve to facilitate mounting while
insuring that the tip of the thermocouple is
in the center of the flue and the copper
sleeve is not in contact with metal
surfaces.
Step 4 - After the thermocouple sleeve is
secure, route the thermocouple wire near
the inlet or outlet water pipe. Use the
third cable tie to secure the thermocouple
wire to the pipe as a strain relief.
Step 5 - Mount the MTU on a wall, joist or
other convenient mounting location using
two screws. Run the cable from the MTU
to the end of the thermocouple wire. Trim
excess MTU cable, as needed. Care
must be taken to protect the cable from
damage by hot surfaces or sharp sheet
metal. Use insulated staples or cable ties
as needed.
Note: Be sure to follow all General
Mounting & Wiring Guidelines outlined in
Publication 471-2000.
Step 6 - Splice the MTU wire to the
thermocouple wire using the two IDCs
provided.
Page 46
● Connect the VIOLET
thermocouple wire to the RED
MTU wire.
● Connect the RED thermocouple
wire to the BLACK MTU wire.
Do not remove the insulation from either
the MTU wires or the thermocouple wires;
the IDC is designed to pierce the
insulation.
Step 7 – Program the MTU using the
MTU Programmer as outlined in the
Programming section of this document.
Step 8 - Return the hot water heater
setting to "Run".
Typical Burner/Fireplace
Application
This procedure covers a typical
installation of a temperature sensing
pulse adapter on a burner or fireplace.
Step 1 - Set burner or fireplace control so
that the appliance does not come on
during installation.
Step 2 - Fasten thermocouple so that the
tip is near, but not in, the flame when the
gas is burning. Use metal clamps or wire
fasteners to secure the thermocouple.
(NOTE: Clamps or wire fasteners are not
provided by Hexagram. Individual
installation conditions will determine the
type of fastener to be used.) A location
must be selected that allows the
thermocouple tip to reach at least 130° C
(400° F). However, the tip temperature
must not exceed 350° C (660° F). If a
pilot light is present, keep the
thermocouple at least 6" away from the
pilot flame.
Step 3 - Route thermocouple wire away
from the appliance.
MTU Instruction
for STAR Submetering MTUs with Pulse Adapters
Step 4 - Mount the MTU on a wall, joist or
other convenient mounting location well
away from the heat source using two
screws.
CAUTION
The MTU must be located
away from the appliance and
ONLY in a location that
remains at room temperature.
Run the cable from the MTU to the end of
the thermocouple wire. Trim excess MTU
cable, as needed. Care must be taken to
protect the cable from damage by hot
surfaces or sharp sheet metal. Use
insulated staples or cable ties as needed.
Note: Be sure to follow all General
Mounting & Wiring Guidelines outlined in
Publication 471-2000.
Step 5 - Splice the MTU wire to the
thermocouple wire using the IDCs
provided. Use a cable tie(s) to provide
strain relief for the wiring.
● Connect the VIOLET
thermocouple wire to the RED
MTU wire.
● Connect the RED thermocouple
wire to the BLACK MTU wire.
Do not remove the insulation from either
the MTU wires or the thermocouple wires;
the IDC is designed to pierce the
insulation.
Step 6 - Secure the MTU wire. Verify
that the MTU cable does not run near the
burner and does not enter any region
where the temperature will exceed 70° C
(160° F).
Step 8 - Reset the burner or fireplace
control so that the appliance can run.
Programming
Note: The 501-7786PT2 MTU requires
Star Programmer Software version 6.0.0
and meter table version 3.85 or higher.
Step 1 - Turn on the Psion MTU
Programmer by pushing On/Esc.
Note: A “Communication Error”
message may occur:
● If an attempt is made to read
and/or program the MTU and the
MTU is receiving input from the

Page 56
The NTG MTU is a special purpose MTU
designed specifically to support the
advanced capabilities of Neptune’s ECoder solid-state register. This MTU
provides the following special functions
when coupled to an E-Coder Plus register
and properly programmed.
•
8-Digit Readings – The NTG MTU
reads and transmits the full 8-digit
reading from the E-Coder at the
programmed read interval, typically
every 12 hours. A full range of
read intervals are supported,
including temporary read intervals
for temporary monitoring purposes.
MTU Instruction
for Neptune and Schlumberger Water Meters
•
Alarm Polling – The NTG MTU
also automatically polls (reads) the
E-Coder alarm indicators every 15
minutes. This happens
automatically, independently of the
standard read interval mentioned
above. If the NTG MTU detects
any change in the alarm status
of the E-Coder Plus register, an
alarm transmission is generated
immediately, reporting the change
in alarm status to the DCUs.
Compatibility with Neptune
E-Coder Registers
Hexagram’s NTG MTU is compatible with
Neptune E-Coder Plus solid state
registers revision 05.98 or higher.
Checking E-Coder Revision
Level
To check the revision level of an E-Coder
register, use your hand to block all light
from striking the E-Coder’s solar cell for
approximately 20 seconds. Then,
remove your hand allowing light to strike
the solar cell. The E-Coder’s display will
briefly flash all 8s, and then reveal a
display like that shown below.
The four digit number at the right of the
display is the revision level. In the
illustration above, the revision level
shown is 05.98.
Compatibility with Neptune
ARB-V and ProRead
Registers
Upon initial installation, an NTG MTU can
also be used with meters equipped with
Neptune’s ARB-V or ProRead registers.
These are standard absolute encoder
registers without the advanced
capabilities of the E-Coder register.
When used with ARB-V or ProRead
registers, the NTG MTU operates in
standard mode, providing 6-digit readings
and no specialized alarm polling.
Note: Auto/ProRead registers must be
programmed by the manufacturer for 3wire mode.
It is important to note that once an NTG
MTU is programmed to function in the
advanced mode with an E-Coder register,
it can no longer be returned to standard
operation. To caution the user, the
display shown below will appear when
first programming an NTG MTU for use
with an E-Coder:
CAUTION!
Once an NTG MTU is
programmed for use with an
E-Coder it can no longer be
used with other (non-E-Coder)
registers.
Page 57
MTU Instruction
for Neptune and Schlumberger Water Meters
Once the user selects Yes on the above
screen and successfully completes
programming the NTG MTU for use with
an E-Coder Plus register, the NTG MTU
can no longer be used with an ARB-V or
ProRead register. From this point
forward, only E-Coder meter types will be
available for selection when programming
this NTG MTU.
Error Codes
When an E-Coder meter type is selected
while programming an NTG MTU with the
MTU Programmer, the MTU attempts to
communicate with the register using a
special protocol that reads the status of
the E-Coders leak, tamper and reverse
flow detection indicators. If the MTU
cannot successfully communicate with
the register, an error code will be
displayed on the MTU Programmer, as
shown below.
Pressing Enter in response to this
display will display the current settings for
the MTU, including the error code, as
shown below.
Page 58
This error indicates one of the following
problems:
•
Attempting to use an E-Coder
meter type with a register that is
not an E-Coder.
•
A defective E-Coder register.
•
Improper wiring between the NTG
MTU and the E-Coder. (Refer to

Installation Procedure
Step 2 - When wiring to the IPT, support
the IPT off of the work surface on the
outside (topside) of its base so that
pressure is not applied to the center drive
shaft. Remove the cable clamp (screw)
from inside the base.
Step 3 – Trim the stripped ends of the
MTU cable to ¼” or slightly shorter. When
inserted into the terminal block, only a
small amount of bare wire should be
visible. Bare wire should not extend
beyond the walls of the terminal block.
This will present a shorting potential.
Step 4 – Feed the MTU input cable
through the sealtight strain relief in the
base of the IPT. Loop the cable so that
stripped ends of the wires can be easily
inserted into the terminal block screws.
The screws should already be open
enough. Place cable clamp over the wire
as shown.
There are two parts to this procedure.
First, the MTU must be wired to the IMAC
Pulsimatic Transmitter (IPT). Once this is
complete, you can then install the
Pulsimatic Transmitter onto the Rockwell
gas meter.
Wiring the MTU to the Pulsimatic
Step 1 – Unpack all of the components
required to install the IPT. This should
include the IPT itself, gasket and a
hardware kit that includes (2 each) brass
threaded rods, stainless flat-washers and
hex nuts.
Step 5 – Insert the BLACK and WHITE
wires into the COM terminal screw.
Tighten the screw.
Step 6 – Insert the RED wires into the NC
BLU terminal screw. Tighten the screw.

screws as they will not be re-used.
Remove the cover. If the cover has the
tamper seal bosses, this cover will be
need to be replaced.
Step 8 – Tighten the nut on the sealtight
strain relief. You will need to tighten the
nut almost fully down (as shown) before it
will bite on the MTU cable.
Step 9 – Check that all wired terminal
block screws are tight.
Step 10 – Depending on the installation
location, you may be able to mount the
MTU at this time. During installation, the
IPT body should be supported so as not
to hang (apply tension) on the MTU
cable. During the installation, do not allow
the heavier body of the IPT to suddenly
jerk the MTU cable as this could
potentially damage the cable internally.
Step 2 – Loosen and remove the screws
securing the index to the index plate.
Save these screws as they will be reused. Remove the index and set aside.
Step 11 – Install the MTU into its
intended location per the recommended
procedure found in the standard
Hexagram MTU installation manual.
Page 69
MTU Instruction
for Rockwell/Equimeter Model 750-10000 Gas Meters
Step 3 – If the index cover screws were
difficult to remove, the threads in the
index plate may need to be cleaned out
before installing the hardware that retains
the IPT. Use the blind-hole tap to
carefully clean out/ clean up the threads
of the (2) cover holes. Blow out the holes
with compressed (canned) air.
NOTE: It is not necessary to clean the
index mounting-hole threads as these
holes are not reused.
Step 6 – Place the IPT (middle set of
holes) over the mounting studs. Make
sure that the IPT drive pin engages the
fork of the meter drive foot.
Step 7 – Mount the register onto the base
of the IPT using the same screws that
originally secured the register to the index
plate (meter head). The drive foot of the
index must engage the fork of the IPT
drive shaft. Tighten/torque the screws to
approximately 4-5 ft-lb.
Step 4 – Thread the (full thread) ends of
the securing studs (2) into the index cover
screw holes of the index plate. Lightly
snug the studs by grasping them by the
flat that is machined into the top of the
stud. Apply the gasket over the studs as
shown.
NOTE: If the index cover that was
removed has the security cap boss
extensions, this cover will need to be
replaced with an index cover without the
security cap bosses.
Step 5 – Before setting the IPT over the
mounting studs, you must align the shaft
drive pin of the IPT so that it will engage
inside the fork portion of the meter drive
foot.
Page 70
Step 8 – Although not necessary, it may
be desired to keep water or dirt from
collecting in the unused corner mounting
holes. If closing them is desired, use a
permanent outdoor rated non-shrinking
putty or caulk such as an RTV.
MTU Instruction
for Rockwell/Equimeter Model 750-10000 Gas Meters
Step 9 – Place the index cover onto the
studs. It will fit over the index one way
only. Apply a flat washer and nut onto
each stud. Snug, and then tighten these
nuts an additional ½ to ¾ turn maximum.
The finished torque value is 25 – 30 inchlb.
Step 10 – Install Wire/Lead security seals

Step 2- Loosen and remove the four
screws securing the index base plate
assembly to the meter. You may discard
these screws as they will not be re-used.
Remove the index box and base plate
assembly from the top of the meter.
Installation Procedure
There are two parts to this procedure.
First, the pulser must be mounted to the
meter. Once this is complete, you can
mount the MTU remotely or directly on
the pulser using the adapter provided. If
you are mounting the MTU on the pulser,
it can be mounted at either the front or
back of the meter.
Step 1 – If necessary, remove tamper
seals from any of the 4 screws that
secure the index base plate and the two
screws that secure the index box to the
base plate.
Note: If the index base plate has integral
security towers like the one on the left
below, it must be replaced with the flat
style index base plate like the one shown
on the right.
Page 108
Step 3 – Disassemble the index box from
the base plate by removing the two
screws that secure the index box to the
base plate. You may discard these
screws as they will not be re-used.
Step 4 – If the index box and/or base
plate mounting screws were difficult to
remove, the threads in the meter head
may need to be cleaned out before
installing the new hardware that will retain
the index base plate, the pulser and the
index box. Use the blind-hole taps to
carefully clean the threads of the index
box and base plate mounting holes.
CAUTION!
The index base plate
mounting holes use a #18-18
thread. The index box
mounting holes use a #12-24
thread. Be sure to use the
proper tap for each hole.
Using the wrong tap will result
in damage to the meter head.
MTU Instruction
for American Model AL800-AL5000 Gas Meters
After using the tap, blow out the holes
with compressed (canned) air.
Step 5 – Place the index base plate onto
the head of the meter. Align the index
base plate with the index plate mounting
holes on the meter head and the large
opening in the base plate is centered over
the drive mechanism.
Step 6 – Break out the tab for either the
front or rear wire exit on the bottom edge
of the pulser body, depending on how you
plan to mount the MTU. (See the
illustration below.)
Step 7 – Assemble the couplers and
shaft to the pulser body as shown in the
illustration below. Ensure that the
magnet is mounted on the Tall Coupler,
and that the retaining shaft is securely
snapped into both the Tall Coupler and
the 2-Pin Drive Disk.
Step 8 – Place the pulser on the index
base plate, aligning the bottom coupler on
the pulser with the wiggler on the meter.
Align the corner mounting holes on the
pulser with the mounting holes on the
index base plate.

gasket on the back of the MTU with the
adhesive surface facing the MTU so that
it aligns over the three mounting screws
and the raised gasket surface of the
MTU.

for Actaris/Sprague/Schlumberger Gas Meters
Step 5 – Next, assemble the couplers
and shaft to the MTU. Place the flat,
disc-shaped coupler on the shaft and
insert the shaft through the front (register)
side of the MTU.
Tighten both screws to a torque not to
exceed 3-5 inch-pounds.
Then snap the magnet holder on the shaft
from the back of the MTU. Ensure that
both couplers are firmly attached to the
shaft.
Step 6 – Now, mount the register onto
the MTU (see illustration below) fastening
the register to the MTU with the #10 x
3/8” screws provided.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Use of power tools is not
recommended.
Step 7 – Check that the register is
properly engaged by rotating the coupler
on the back of the MTU and observing
the register dials.
Start the two screws into the mounting
holes, and then slide the register beneath
the screws, making sure that the wiggler
on the register is aligned with the MTU
coupler.

for Actaris/Sprague/Schlumberger Gas Meters
Step 8 – Next, thread alignment studs
into the threaded mounting holes on the
left and right side of the adaptor, as
shown below.
Step 10 – Now, slide the clear register
cover over the alignment studs while you
hold the MTU in position with your free
hand.
Step 11 - Next, insert one of the #10-24 x
2” screws through the top-center hole on
the clear register cover. Tighten this
screw just sufficiently to hold the MTU
and register cover to the meter.
Step 9 – Next, slide the MTU over the
alignment studs, positioning the coupler
on the MTU to ensure that it engages
correctly with the wiggler on the gas
meter.

for Actaris/Sprague/Schlumberger Gas Meters
Step 12 – Next, remove one of the
alignment studs and replace it with
another one of the #10-24 x 2” screws
provided. Continue in a similar manner,
replacing the other alignment stud with a
#10-24 x 2” screw. Tighten all three
screws to a torque not to exceed 12 -15
inch-pounds. The gasket should be
compressed slightly. Be careful not to
over tighten the screws. Excessive torque
may damage the MTU enclosure.
Because of this, power tools are not
recommended for this procedure.
Step 14 – Once Installation is complete,
program the MTU using your field
programmer and the STAR Programmer
Software.
Step 13 - Replace any anti-tamper,
safety, or security hardware onto the
plastic cover as required.
