Introduction
Fault Trapper™ is a new class of tester intended to locate the distance to a circuit anomaly that is either intermittently causing a change in the circuit’s characteristics or blowing the circuit breaker.
Fault Trapper™ can capture and save up to two events (open and/ or short) per test session and save them separately. If the circuit breaker trips, the backup battery powers the Fault Trapper™ to allow for an orderly shutdown. The last faults can be viewed using the battery power. An In-Line Adapter is used to isolate the circuit being monitored from the breaker panel and all other breakers.
Key Features
• Unattended in-line monitoring of energized dedicated circuits up to 300 VAC and 40 amps
• Fault Location reported as distance from Fault Trapper™
• Detects a fault whether or not it trips the circuit breaker
• Timer logs elapsed time of tests
• Back-up battery allows capture of breaker trips/Unpowered display of results

Instructions for Use
After connecting in one of the configurations above and switching on the breaker(s).
1. Powering on Unit – Once the unit is powered by the AC power connection the battery level will be shown on the display. The unit will be ready at this point to run a test.
If there is no AC power connection the Display button can be used to power the unit on using battery power to show the results from a previous test.
2. Starting a Test
– While powered by the AC power connection press the Test button. The Fault Trapper will not run a test under battery power. The velocity of propagation used for distance measurement is 70% the speed of light, a nominal value for power wiring, and is not configurable.
Before you start, note the time.
The Fault Trapper displays the elapsed time from when you start the monitoring to when the fault occurs. You will need to know the starting time to determine when the fault occurred.
3. Test Running – When a test is started “zero’s” will be scrolling left to right in the test results area and the up down arrows on the left side will be flashing until a fault is shown.
Once a fault is found the up down arrows will continue to flash while the test is running while the distance to the last fault found is shown.
The lower left portion of the screen denotes the time. Before a fault is found the time will show how long it has been since the test started. Once a fault is found the last fault will be shown and the time will show how long the time was between the beginning of the test and the last fault found.

4. Stopping a Test – The three ways a test can stop are:
a. When the AC power goes down, b. The Test button is pressed c. The Ignore button is pressed.
When the AC power goes down the unit will run on battery power for long enough to finish scanning for the fault which may have caused the AC to power off (breaker trip). If a fault occurred within the last several seconds before the AC went down it will be classified as the “Breaker Trip Fault”, the “Voltage!” icon will be displayed when this occurs.
A non-breaker trip fault (if found earlier during the test) will also be saved. When the Test button is pressed during a test any fault found will be saved as a “Non-Breaker Trip Fault” and testing halted. A second press of the Test button will restart testing.
5. Ignore Feature – The ignore function allows for ignoring a fault location that is being reported under normal operation of the circuit. The primary use would be when a load which causes “faults” during testing that are not important and should be ignored to make it easier to find real wiring issues. One example would be an air conditioning compressor cycling on and off.
A fault that trips the breaker will be shown in the results regardless of whether or not the fault was ignored.
If the displayed fault is to be ignored, press the IGNORE button briefly. The test will stop running and alternate between displaying the current fault to ignore and displaying “IGN” until the
Setting an Ignore - To save an ignore
test is restarted.
location press the Ignore Button for a short time. When an ignore is set the Fault Trapper will alternate showing the distance to be ignored and “IGN” until testing is resumed. If the Ignore Button is pressed while a test is running the test will be stopped and the last fault found will be saved. If the test is not running the fault to be ignored must be chosen using the Display Button to toggle to the fault to be ignored and then a short press of the Ignore Button will save that location. The ignored location will continue through power cycles of the
Page 15 of 24

www.planumtools.com
Fault Trapper. When powered on with AC power the ignore location will be shown on the screen and “IGN” will be displayed in the lower left corner of the screen.
Clearing an Ignore – To clear an ignore location press and hold the Ignore Button until “CLR” is displayed on the screen.
6. Test Results - The Display button is used to show test results. If the AC power connection is off the unit will use the 9 volt battery to power on the display and show the results from the last test. There can be a “Breaker Trip” fault and a “Non-Breaker Trip” fault. The voltage icon will flash indicating that the fault shown caused the breaker to trip. Tap the Display button to cycle between the two faults (if there are more than one). Ft and M units can be toggled by holding down the Display and Ignore buttons for 3 seconds.

Displaying Results using DISPLAY Button
Testing Stopped with No Results
7. Battery Remaining – In the lower right portion of the screen is a battery icon with bars showing how much remains for the 9V battery. Three bars shows a full battery, two bars is between 33% and 66%, one bar is between 33% and 10%. A flashing battery outline icon shows that there is less than 10% battery life remaining.
Since the test runs for a short time after the AC power shuts off it is recommended to replace the 9V battery (with no AC power present) once the battery indicator shows one bar or a flashing battery outline icon.

Fault Trapper™ FAQ
Does the Fault Trapper Require Batteries?
- Yes, the Fault Trapper requires a 9V battery in the event of Power Loss from the wires under test. The Fault Trapper requires a high quality welded cell 9V battery such as Duracell®. Generic budget batteries may not be sufficient to power the Fault Trapper.
The Fault Trapper main unit does not power up when it is connected to AC power.
- Check that the Fault Trapper is connected correctly.
- Check the fuse in the 40A Adapter Module. If the fuse is blown, a replacement can be ordered from Digi-Key® at www.digikey.com, P/N F4603-ND.
The Fault Trapper does not see a fault when I short the wires to trip the breaker intentionally.
- If the ignore button has been pressed, the Fault Trapper will ignore the fault. Press and hold the Ignore button until the LCD displays “clr”, this clears the ignore feature.
Does the Fault Trapper and 40 Amp Adapter Module work in wet environments?
- No, the Fault Trapper and 40 Amp Adapter module must be operated in dry environments.
Can I use my own longer or shorter Banana Jack leader cable between the Isolation module and main unit?
- No. The impedance, length and voltage rating is critical to safe and correct operation of the unit.
My unit seems to work fine, but doesn’t save the last event detected.
- The battery must have enough energy to run the unit for 5 seconds on battery power alone. If your battery is low or poor quality, the unit may not be powered on long enough to save the results.
The Fault Trapper doesn’t report the breaker tripping because of sustained over-current loads; I thought it would tell me where the fault is.
- The Fault Trapper does not measure current. The Fault Trapper is designed to locate actual wiring faults. If the over-current event is

www.planumtools.com
from a wiring short (not just the load at the end of the run) it will be detected as a short at the event distance.
How can I get the latest information on my Fault Trapper?
- Go to www.platinumtools.com for manual updates, more FAQs, and other important information.
Will the Fault Trapper detect series and or Parallel arc faults?
- It depends on the nature of the connection/parallel arc event. When the Fault Trapper detects an open or loose wire connection for 5 half AC cycles in a row (33mS) it will be reported as an open fault. Parallel arc detection takes 5 half AC cycles with low impedance to be detected as a short fault. In the case of parallel arcing, if the shorting material is blown out, blown apart, vaporized or someway removed before the 5 half cycles, it may not be detected as a fault.
How far down a daisy-chained branch circuit would the Fault Trapper be able to detect faults?
- The Fault Trapper is optimized for monitoring homerun circuits. Using it to monitor circuits that extend beyond a homerun may detect a fault but the accuracy of displayed distance to the fault maybe affected.
Sometimes the circuit breakers are due to ground faults, will the Fault Trapper detect this?
- The Fault Trapper is capable of detecting electrical events due to shorts and opens between hot and neutral lines. It will not detect events due to ground-faults.
Most circuits in a breaker box use dedicated neutrals for each line, however, there are cases where two hot wires may share a common neutral. Would this compromise the Fault Trappers ability to detect a fault?
- The two hot wires have to be different phases, effectively a 240V line using 120V to the neutral from each phase instead of using the 240 available across the two hot wires. This should not be a problem for Fault Trapper. Connect Fault Trapper to Hot line to be monitored and the neutral bus as shown in 120V hook up section.
