INTRODUCTION

IMPORTANT NOTES

1. This manual is for installation on single phase or split single phase 120V/240V electrical systems only. The

CT installation described in this manual will not work for three phase service. This also applies to
120V/208V panels which uses two phases of a three phase source.

2. Safety is paramount! Read all safety notices and make sure you fully understand and follow the safety rules.

GEM MODELS

You should first determine which communication option (if any) is installed
in your GreenEye Monitor: “GEM”, “GEM-WE” or “GEM-E”

Base model “GEM”

Strictly uses RS-232 for communication with the DashBox or other
data host. All GEM devices have RS-232 by default.

This model is identifiable by the fact that there is no antenna

connector such as “GEM-WE” model and the lack of the additional
reddish circuit board like the “GEM-E”. See picture on the right.

Introduction

WiFi/Ethernet “GEM-WE”

Has the option of WiFi, Ethernet or RS-232 for communication with
the DashBox or other data host.

You can easily identify this model by the presence of a WiFi antenna
connector. See picture on the right.

Ethernet Only “GEM-E”

Has the option of Ethernet or RS-232 for communication with the
DashBox or other data host.

This model is easily distinguishable by the presence of the reddish
colored circuit board installed. Notice that the Ethernet connection
is done on the module and NOT the jack on the blue GEM board.
Additionally, the black barrel jack on the module is not used or
functional.

Important Safety Information

Read All Safety Rules Before Installing!

IMPORTANT SAFETY INFORMATION

WARNING !

All safety rules described below must be obeyed. Read safety information carefully before proceeding with the
installation of the GreenEye Monitor and associated current transformer.

The GREENEYE MONITOR (GEM) is a low voltage device. This requires that all external connected signals be a low
voltage (<50V) and provided by Class II approved power supply.

All of our power supplies are UL, CSA or UL/c approved for use in USA and Canada. Our current
transformers (CT) are UL/c listed. No direct line connections to the GEM are allowed. All signals
must be galvanic isolated from the power-line.

Never install the GEM inside an electrical panel. A separate “low voltage” panel may be used when needed.

The GREENEYE MONITOR (GEM) installation requires the installation of current transformers (CT) installed inside the
electrical service panel. This portion of the installation MUST be performed by a qualified electrician or individual. The
installer must follow all local safety codes and use proper safety practices and equipment.

The qualified installer must be aware that main panels may still contain dangerous voltage levels even though the main
breaker is in the “OFF” position.

The following rules MUST be obeyed!

 Any work performed inside the electrical panel must be done by an electrician or qualified individual. This

individual will be familiar with the local electrical code and perform the installation accordingly.

 NEVER install the GreenEye Monitor (GEM) inside the electrical panel. Only low voltage (12VAC or less)

galvanic isolated connections are to be made to the GREENEYE MONITOR (GEM) terminals.

 The current transformer (CT) leads must exit the electrical panel through an appropriate box connector, strain

relief or bushing. The CT leads must be properly anchored on the outside of the panel.

 The portion of the CT leads inside the panel must not have any damage, cuts or wear to the outside

insulation.

 The CT leads inside the electrical panel must be routed in such a way that its insulation will not be rubbing

against live terminals. Care must be exercised not to pinch the CT leads especially when re-installing the panel
cover.

 Do not install the CTs in panels with voltages greater than 300V.
 Do not install the GREENEYE MONITOR (GEM) in a wet location.

GEM Mounting Location

NEVER Install the GREENEYE MONITOR (GEM) Unit Inside the Electrical Panel

GEM MOUNTING LOCATION

Find suitable mounting location for the GEM. Do not mount the GEM inside breaker panel!

WARNING !

Make sure the CT lead will reach the furthest circuit breaker.

Determine the best mounting location for the GEM taking into consideration the length of the CT leads. Some CT models
have longer leads than others. The two large main panel CTs such as
SPLIT-100 or SPLIT-200 have longer leads than Micro-CTs do, so it may
be preferable to locate the GEM at the opposite end of the panel feed
where the large CTs are installed. See diagrams below.

 Page 6

DashBox Location

The DashBox is located within two feet from the GEM

DashBox is located a distance from the GEM by extending the STS Cable

The DashBox is located near the GEM and connects using WiFi

DASHBOX LOCATION

The possible location for the DashBox depends on the GEM’s communication options (if any) installed. All GEM models
have RS-232 ports and qualify for “Option 1”. This option is recommended because it allows the DashBox to collect data
independent of the network status or even without a network.

OPTION 1: RS-232 CABLE
(RECOMMENDED)

Model: GEM / GEM-WE / GEM-E

This option uses RS-232
communication between the GEM and
the DashBox. All GEM models are
compatible with option.

The STS Cable is 3 feet long therefore
the DashBox should be mounted
within two feet of the GEM.

The STS cable may be extended to
allow the DashBox to be located in
another room. It is recommended to
use CAT 5 or CAT 6 network cable to
extend the RS-232 STS cable.

 Page 7

OPTION 2: TCP CONNECTION

Model: GEM-WE / GEM-E

Option 2 uses the network as the path for data
from the GEM to be sent to the DashBox. This
option is only possible with GEM models listed
above.

The GEM can be connected to the network via
Ethernet Cable or in the case of WiFi/Ethernet
GEM models, WiFi connected.

Option 2 is not as reliable as Option 1 which
consists of an RS-232 connection since any
network downtime will affect data collection.

NOTE: GEM-E is not capable of WiFi connection.

PANEL LAYOUT

A generalized panel layout sheet is located on the last page of this document. Print a copy and fill in the information for
each breaker. This will greatly simplify setting up the GEM CTs and DashBox channels later. Each field is defined below.

The picture (below) shows part of the channel info sheet on the left and a section of breakers represented.

FIELDS

Panel #

Load Description

CT #

CT Model

“Panel #” is the breaker slot number on the panel itself

“Load Description” is the name of the appliance, outlet, light, etc. connected to this breaker

“CT #” is the number on the CT leads. This allows the installer to know which CT leads represent each

channel when it comes time to connecting the leads to the GEM.

Not all CTs have numbered labels attached. If this is the case, it is advisable to put a small piece of
masking tape at the end of the CT leads after the CT has been installed and the leads have been routed
outside of the panel

“CT Model” is the Brultech model number of the CT

Amps

“Amps” is the amperage rating of the circuit breaker

240V-120V-240V

Circle the voltage that represents the breaker. If it’s a 240V breaker it is typically coupled with a breaker
adjacent to it. In this case, circle the two together as shown in the picture above.

 Page 9

Read and understand the safety information before the CT installation!

CT INSTALLATION

WARNING !

Read the Important Safety Information chapter at the beginning of this document
before proceeding with CT installation!

CT ORIENTATION

The CT orientation is best understood by looking at the picture on
the right. For each of the CT styles the CTs are shown mounted in
opposite direction.

Paying attention to the side of the CT where the leads exit, notice
that in one case this side faces toward the circuit breaker and in the
other case, away from the breaker.

If only one CT is connected to a given channel, the GEM doesn’t care
about orientation.

All CTs may be installed in any direction but once the CTs have been
installed, make note of the CT orientation for both CTs when two CTs
are connected to a 240V load to be monitored by a single channel.

CT Installation

240V LOADS

You can monitor a 240V load with only one CT if the load is balanced.
A balanced load is one that does not use a neutral conductor
therefore the current which flows through one line is identical to that which flows through the other. If you are not sure
if the load is balanced, use two CTs. If using a single CT for the 240V load, orientation is irrelevant.

Typical 240V Balanced Loads

Central air condition system, water heater, baseboard heater, water pump

Typical 240V Unbalanced Loads

Clothe dryer, electric range

ROUTE THE CT LEADS

Neatly route all of the CT leads through one of the many “knock-out” holes of the GEM enclosure. In some installations,
the leads may enter the GEM through the back of the GEM enclosure.

 Page 10

CT Termination

CT TERMINATION

GEM TERMINAL STRIPS

NOTE: The CT leads must be stripped approximately 10mm (0.4”) and have a
gauge size between 18 and 26 AWG.

The GEM uses spring loaded terminal blocks. The CT leads must be stripped the
proper length. If the leads have stranded wire, it is preferable to “tin” the wire
beforehand to prevent dealing with frayed ends. (Tinning is the process of
adding solder to bond all of the strands together).

The CT leads are inserted into terminal block while pressing down on the
corresponding orange tab (see picture below).

1. Align the two lead ends with the terminal holes. This can be done one lead at a time however it may be easier

inserting both leads at the same time, providing they are tinned with no frayed ends.

2. Press down on the orange TAB(s) corresponding to the lead or leads to be inserted, using a small “flat blade”

screwdriver.

3. Insert the leads into the terminal block while making sure the leads are perpendicular. In most cases, both CT

leads can be inserted at the same time. If the lead was stripped back 10mm, then the stripped section should be
entirely inside the block with only the insulation visible.

4. Release the pressure to the spring tab.

5. Finally, tug slightly on the leads to make sure they are secure.

 Page 11

CT TERMINATION

The picture on the right shows the terminal block. Each block has four terminals.
Terminal 1 is at the bottom. The terminals that the CT will be connected to are
dependent on the type of CT used.

Two types of current transformers are used with the GEM: Types A and Type B.

The difference between each type has to do with the type of signal which represents the
sensed current:

TYPE A CT: The measured current is represented by a voltage output signal.

(SPLIT-60, SPLIT-100, SPLIT-200, SPLIT-400/600, SPLIT-170)

TYPE B CT: The measured current is represented by a current output signal.

(Micro-40, Micro-50, Micro-80, Micro-100)

CT Termination

SINGLE CT CONNECTION

When only one CT is connected to the GEM it doesn’t matter which color lead goes to each terminal.

 Page 12

CT Termination

CONNECTING TWO CTS ON ONE CHANNEL

Two Type “A” CT Connection

The following CT models are “Type A”: SPLIT-30, SPLIT-60, SPLIT-100, SPLIT-200, SPLIT-400/600, SPLIT-170

When connecting two CTs to a given channel, the CT orientation and lead color needs to be taken into account to
prevent the signal of one CT from subtracting from the other.

When two CTs from a 240V load are connected to the GEM as shown in the diagram to the right, the rule for the CT lead
color code is as such:

If the two CTs are installed facing opposite directions:

Terminals 1 & 3 will have the same color lead
Terminals 2 & 4 will have the same color lead

If the two CTs are installed facing the same direction:

Terminals 1 & 4 will have the same color lead
Terminals 2 & 3 will have the same color lead

This rule is based on a 240V load which means that one CT is on phase A and the other on phase B.

If both CTs are connected to two different loads which happen to be on the same phase, then the rule described is the
opposite!

Example:

Two SPLIT-200 CTs are connected to the main feeder. They are installed with both CTs facing the main panel
breaker.

 The solid black lead of CT#1 is connected to terminal #1 and the other lead to terminal #2
 The solid black lead of CT#2 is connected to terminal #4 and the other lead to terminal #3

 Page 13

Power Supply and Wall Transformer

Two Type “B” CT Connection

The following CT models are “Type B”: Micro-40, Micro-50, Micro-80,
Micro-100

When two CTs from a 240V load are connected to the GEM as shown in the
diagram to the right, the rule for the CT lead color code is as such:

If the two CTs are installed facing opposite directions:

Terminals 2 will have the same color lead from each CT
Terminals 3 will have the same color lead from each CT

If the two CTs are installed facing the same direction:

Terminals 2 will have dissimilar color lead from each CT
Terminals 3 will have dissimilar color lead from each CT

This rule is based on a 240V load which means that one CT is on phase A and the other on phase B.

If both CTs are connected to two different loads which happen to be on the same phase, then the rule described is the
opposite!

Example: Two Micro-80 CTs are connected to the electric stove. They are installed with both CTs facing the breaker.

 The white lead of CT#1 and the black lead from CT #2 are connected together to terminal #2
 The black lead of CT#1 and the white lead from CT #2 are connected together

to terminal #3

SPLIT-30 CT Connection

The SPLIT-30 is a “Type B” CT and the connection method for Type B
described above applies.
The only difference is the addition of a capacitor inserted in terminals 1
and 4.

POWER SUPPLY AND WALL TRANSFORMER

Plug the 5Vdc power supply and the 12Vac wall transformer into a receptacle near the
panel.

1. Plug the 5Vdc cable into the barrel jack (top right of picture)

2. Fully plug the 12Vac cable into the 3.5mm jack (bottom right of picture). It is

absolutely important to make sure that the plug is fully inserted!

GEM Setup Procedure

NETWORK SETUP (GEM WITH WIFI/ETHERNET)

If the GEM is connected to the DashBox using RS-232 (STS Cable), then skip this chapter.

The next step is to have the GEM send packets directly to the DashBox which are both connected to the same network.
The GEM needs to know the IP address and port number of the DashBox. The DashBox IP was determined earlier.

For GEM with WiFi/Ethernet option

Model: GEM-WE

Perform the next steps ONLY if the GEM uses a WiFi/Ethernet module!

1. Select the “Network” menu

2. Enter the DashBox IP address (determined earlier) in the “Host IP Address or URL Address:” box

3. Enter “80” for the port number (don’t include the quotation marks)

4. Click “Save”

GEM with Ethernet only option

Model: GEM-E

Perform the next steps ONLY if the GEM uses an Ethernet only module!

1. Open the GEM Network Utility program downloaded from the Brultech website

2. Select the “Ethernet Only” tab

3. Click “Search”. The GEM will be discovered and the fields populated

4. Enter the DashBox IP address (determined earlier) in the “Server IP” box. Ex: 192.168.0.48

5. Enter 80 for the “Remote Port” number

6. Click “Save”

Having completed these steps, the GEM is now sending data packets to the DashBox over the network.

Net Metering

NET METERING

SETTING CHANNEL POLARITY

By default, all GEM channels will display a positive value regardless of CT polarity. Grid connected solar or wind power
generation may generate more power than consumed. This results in a reversal of the electrical flow. The GEM can read
the direction of flow and show it as a positive amount when consuming and a negative amount when selling to the grid.

To allow the GEM to net meter, the “Main Panel” and “Solar” inverter channels need to be set to “Polarized”. The

screen shot below shows channels “1” and “27” set to “Net Metering” which will make the channels power polarized.

Procedure to change a channel to “Net Metering” (refer to screen shot above):

1. On the GEM Setup page, click the “Channel Option” menu

2. Enter the channel number for the “Main Panel” feed

3. Click the “Net Metering” radio button

4. Click “Save”

The area indicating the channel number will now change from blue to green. You can click “Live Data” to see if the main
panel channel is displaying the proper polarity. The watt value should be positive if consuming power and negative if
selling generated power. There is a 50/50 chance that the polarity is wrong. If so, then toggle the polarity(next).

TOGGLING THE POLARITY

In the “Toggle Single Channel Polarity” box:

1. Enter the channel number that is showing the wrong polarity

2. Click “Save”

Notice next to the channel number, the value in the brackets has now changed from “0” to “1” or from “1” to “zero”.
Once you have set your polarized channels, be aware that the PT (12Vac wall transformer) can affect this. See next

 Page 28

Net Metering

EFFECT OF THE PT ON POLARITY

It is important to understand that the polarity of the PT (12Vac wall transformer) will change the polarity of any channel
that is “net metering” enabled (highlighted in green). For instance, if the wall transformer (PT) is unplugged turned 180
degrees and re-plugged such that the 120V receptacle blades are reversed, all net metering enabled channel polarities
will change. See Error! Reference source not found. below.

Temperature Sensors

TEMPERATURE SENSORS

1-WIRE BUS

The GEM reads temperature using a “1-Wire” bus network. This system requires only three wires to address many
temperature sensors connected to a common line (see diagram below). The GEM design accommodates up to eight
sensors.

COMPATIBLE SENSORS

The GEM can accept the following two very common temperature sensors:

1. DS18B20

2. DS18S20

These are both very common and low cost. The DS18B20 is the most popular type.

 Page 30

Pulse Count

PULSE COUNT

The GEM has four pulse count inputs. Pulse counter #1 and #2 are totally isolated from the GEM ground and circuit. If
using any of these inputs, a DC pulse signal between 3V and 24VDC is required.

Pulse counters #3 and #4 are “dry” contact type counters. These inputs require switch contacts not connected to any

power source, such as relay contacts or magnet switch contacts. Very low voltage from the circuit (5VDC) is used to
complete the circuit.
