Safety Precautions

DANGER Hazardous Voltage. Will cause death or serious injury. Only to be used by

qualified personnel.

Turn off and lock out power supplying equipment before installing AFCI.

Safety Instructions

1. AFCI circuit breakers must be installed and serviced by a qualiﬁed electrician only.

2. To be installed only on a single phase 120VAC grounded system.

3. To prevent severe shock or electrocution, always turn the power off before working on or inside

equipment.

4. Replace all doors and covers before turning on power to this equipment.

Do not open. No user serviceable parts inside. If damaged, please return to Siemens Industry Inc. at:

 Parkway Lane

Peachtree Corners, GA , USA

WARNING: This device is only for use on single phase V circuits. DO NOT connect to higher

voltage electrical supplies. Connecting this device to any circuit with voltages above V will

cause damage to the equipment and could result in injury or death.

CAUTION: DO NOT use if device appears damaged in any way.

Hazard of Equipment Damage. Will cause Damage to the AFCI Module. Do not reverse-feed or

back-wire. Do not subject to megger, high voltage, or hi-pot test. Remove the breaker before

hi-pot occurs on the system or on the circuit.

Risk Of Danger

It is important that users of this device read, understand, and follow all warnings, cautions, safety

information, and instructions in this manual before operating this device. Failure to follow instructions

could result in death or serious injury.

Quick Start Guide AFCI Diagnostic Circuit Breaker

Purpose

The purpose of the Arc Fault Circuit Interrupter (AFCI) Diagnostic Breaker is to help identify and diagnose

why AFCI breakers may be tripping. AFCI breakers monitor electrical signals on the wiring for conditions that

are present during an arc-fault event. Commonly, this is due to loose, frayed, or damaged wiring. Some-

times, this can be attributed to inadequate filtering of RF noise from devices in the home. The diagnostic

tool helps pinpoint the root cause by taking measurements of these signals.

Setup

Connecting your Mobile Device to the Diagnostic Breaker

. Replace AFCI breaker that is known to trip

with Diagnostic Breaker

. Turn Diagnostic Breaker ON.

. To begin pairing, press and hold PTT

button on breaker until the PWR LED

begins to blink. This takes approximately

 seconds.

. When breaker is available, it will populate

as shown in the image. If the screen does

not populate, click the refresh icon at

the top of the screen.

Android

• Tap the breaker to connect

• Device will auto connect

iPhone

• Tap the breaker to connect

• When asked for a PIN to pair, enter

AFCI Diagnostic Circuit Breaker Quick Start Guide

Menu Overview

Status Screen

The Status screen will provide basic data about the breaker connected. The most useful section for this

screen is the RF Noise Level. Watch for levels that fluctuate or exceed the Green bars for any potential

unwanted trip issues. In addition to RF Noise, the Load Current can be monitored.

RF Noise may cause unwanted tripping with

enough Load Current. The more bars, the more

likely RF noise interference is causing unwanted

tripping.

Use waveform data (using the Record tab) to help

determine if the noise is an issue.

Breaker connection status is displayed at the top of

the App.

NOTE: The phone must remain within  feet of

the breaker to maintain connection.

In addition to RF noise, the Load Current can be

monitored.

There are  menu options located at the bottom

of the screen.

Capturing Data

Download a previous Waveform Capture – Last Trip Waveform

Use this setting if the breaker was installed and has recorded a trip event.

After the breaker trips, reconnect to the breaker by turning the breaker OFF then ON. Next press the bluetooth

icon in the top right corner. If the breaker does not reconnect, follow the steps described in the Connecting

you Mobile Device to the Diagnostic Breaker section of the guide.

Next, follow the steps below:

. Tap Record from the bottom menu options.

. Under the Settings header, click the

arrow to expand the menu options.

. Choose “Last Trip Waveform” as the Trigger

Source.

. Tap Save Settings.

. Expand Record Info and enter site

information.

. Expand Graph.

. Scroll down until you see the blue Record

button:

Setting Up a Waveform Capture – Last Trip Waveform (continued)

Once you tap the Record button, the app will display

“Waiting for capture”, as shown in the image.

A few seconds later, the breaker should display the

message “Fetching records”. Then, the graph will update

with the information that was stored from the last trip

event.

If you do not see the “Fetching Records” prompt. You may

be too far away from the load center. Ensure you are

within  ft. of the load center.

After the breaker loads the data, a graph will be displayed,

showing Load Current and RSSI (RF noise).

Tap the icon to save the graph to your mobile device

to view later or share later using the History tab.

Tap the icon to share the data via email.

TIP: You can also pinch to zoom on the graph to change

the x-axis and y-axis scaling.

Setting Up a Waveform Capture – Manual Trigger

Use the Manual Trigger option if you would like to capture a live snapshot of the diagnostic breaker. This

may help identify RSSI (RF noise) that exists in the background contributing to arc-like characteristics.

If no trip can be captured, use Manual Trigger.

This setting is used to manually capture data at

the moment “Record” is pressed.

. Tap Record from the bottom menu

options.

. Under the Settings header, click the

arrow to expand the menu options.

. Choose “Manual Trigger” as the Trigger

Source.

. Tap Save Settings.

A few seconds later, the breaker should display the

message “Fetching records”.

A waveform from the manually triggered event will then

be displayed in the Graph section.
