Neptune E-CODER User manual

E-CODER® Quick
Install Guide

1: General Instructions
The E-CODER®is an electronic absolute encoder
register designed for use with Neptune's Automatic
Reading and Billing (ARB®) System. This register
operates with Neptune's R900®and R450™ MIUs,
providing advanced features such as leak, backflow,
and tamper detection.
With the E-CODER register, both the homeowner and
the utility can use the following features:
lNine-digit display for visual reading
lEight digits for billing
lWater flow indicators
lIntermittent and continuous leak detection icon on
the LCD panel
This guide helps you identify and read information
displayed on the E-CODER register. It also helps you
recognize the common causes of leaks and instructs
what to do if you find one. This guide contains steps to
determine whether a leak is fixed after repairs.

3: Wiring the Inside Set Version
Follow these steps to run a three-conductor cable
from the E-CODER®register to the MIU.
1. Connect the three-conductor wire to the encoder
register’s terminals as described in the
manufacturer’s instructions, using the color code
in step 3. The encoder terminal uses three wires:
black, green, and red.

Neptune recommends Novagard G661
or Dow Corning Compound #4.
Novagard may cause irritation to eyes
and skin. If swallowed, do not induce
vomiting; dilute with one to two glasses
of water or milk and seek medical
attention. Please refer to MSDS
Novagard Silicone Compounds &
Grease Inc. 5109 Hamilton Ave.
Cleveland, OH 44114, 216-881-3890.
For copies of MSDS sheets, call
Neptune’s Customer Support at
[phone].
7. Place the terminal cover
on the register, ensuring
the wire is routed
through the strain relief.

4: Wiring the Pit Set Version
Complete the following steps to wire the pit set
version. The following figure shows the components
required for installation.
Figure 8: Installation Components
Figure 9: Scotchlok™ Connector
1. Hold the
Scotchlok™
between your
finger and thumb
with the colored
cap facing down.
Do not strip the colored insulation from
the wires or strip and twist the bare
wires prior to inserting them into the
connector. Insert the insulated colored
wires directly into the Scotchlok
connector.
- 7 -

2. Take one non-
stripped black wire
from the pigtail and
one from the
receptacle / MIU and
insert the wires into
the Scotchlok
connector until fully
seated.
Figure 10: Seating
Connector Wires
Figure 11: Crimping Tool
3. Place the connector
color cap side down
between the jaws of
the crimping tool. For
part numbers, see
Table 2 on page 14.
4. Check to ensure that
the wires are still fully
seated in the
connector before
crimping the
connector.
Figure 12: Improper
Connections
5. Squeeze the connector firmly with the proper
crimping tool until you hear a pop and gel oozes
out the end of the connector.
6. Repeat steps one through five for each color wire.
See Table 1 on page 9for the wiring configuration
to connect Neptune®MIUs or competitor MIUs to
the E-CODER®.

5: Installing Networked Receptacle /
Dual Port MIUs
Enhanced R900®v4 MIUs are not dual
port capable. These instructions apply
only to v3 MIUs.
The Dual Port R900 and R450™ MIUs work only with
Neptune®ProRead™ or E-CODER®registers. Each
register must be programmed in “RF Network” mode
prior to installation.
E-CODER registers cannot be
programmed while connected together
in a network. Program them separately
before making the network connection.
The designations HI and LO are
Neptune's designations for the high (HI)
flow or turbine side of the compound,
and the low (LO) flow or disc side of the
compound.
- 10 -

The settings can also be used to
designate the primary (HI) and
secondary (LO) meters in a dual set
application.
Programming the HI Register
Complete the following steps using the Neptune field
programmer to select the ProRead Program tab for
programming.
1. Select RF Compound HI
format.
2. Select connectivity 2W.
3. Match the Dial Code 65.
4. Type the appropriate
register ID.
5. Program the register.
6. Read or query the
register to confirm
correct programming as
shown in this figure.
Figure 17: HI Register
- 11 -

Programming the LO Register
Use the Neptune field programmer to select the
ProRead Program tab for programming.
Figure 18: LO Register
1. Select RF Compound LO
format.
2. Match the Connectivity
2W.
3. Match the Dial Code 65.
4. Type the appropriate
Register ID.
5. Program the register.
6. Read or query the register
to confirm correct
programming.

6: Wiring Networked Registers
Complete the following steps to wire the networked
registers.
1. Connect each color wire with the appropriate color
wire from the pigtail and both registers, until all
three colors have been successfully connected.
Figure 19: Interconnection of Like Terminals
Remove any bare or non-insulated wire.
Insert only insulated wire into the splice
connector.
Observe proper polarity as shown in the
above figure, when wiring the registers
so that all terminals are interconnected
with wires of the same color: red, black,
or green.
2. Proceed with "Activating the E-CODER®" on page15.

7: Crimping Tool Manufacturers
To apply the Scotchlok™ connectors, you need a
proper crimping tool. The following table shows a list
of various manufacturers and model numbers.
To reduce fatigue, use a tool within each
splicing group with the highest
mechanical advantage indicated within
the parentheses ( ).
Manufacturer Model Number
3M lE-9R (10:1)
lE-9BM (10:1)
lE-9C/CW (7:1)
lE-9E (4:1) E-9Y (3:1)
Eclipse Tools 100-008
Table 2: Crimping Tools
Use of normal pliers or channel locks is
highly discouraged because they do not
apply even pressure and can result in an
improper connection.
- 14 -

8: Activating the E-CODER®
To read the E-CODER®you must first activate it.
Complete the following steps to activate the E-CODER.
1. Expose the E-CODER to sunlight or activate with a
flashlight for five seconds.
If you can power on the LCD, but there
is insufficient light to read the ASCII, the
LCD displays LO Light.
Figure 20: LCD Displays LO Light
Verify the following LCD displays the :
lAll-Segment test
lVersion number
lFlow rate
The display alternates between the reading and the
flow rate.

10: How to Tell if Water is in Use
To determine if water is in use, complete the following
steps.
1. Watch the flow indicator for two minutes.
2. Determine which of the following conditions exists.
If the arrow is:
lFlashing, then water is running very slowly.
lContinuously on, then water is running.
lNot flashing, then water is not running.
What To Do In Case of a Leak
The following checklist can be helpful if the E-CODER®
leak indicator shows a possible leak.
Check all faucets for possible leaks.
Check all toilets and toilet valves.
Check the ice maker and water dispenser.
Check the yard and surrounding grounds
for a wet spot or indication of a pipe leaking.
