Introduction
1.1.
Overview
The PFM 200N Series has been specially engineered for testing virtually every known type of dropout pulses in
automotive applications.
One special feature of this device is the capability of the generator to switch a load in parallel to the DUT during
the dropout test.
For example, the PFM 200N series is for testing of E10 Short interruptions and E13 Pin Interruption for the
following tests:
- OEM LV 124 Version 2.20 (2013-02)
- VW 80000 2013-06
Note: Due to changes in LV 124, the 2009 version of the standard is no longer supported by the PFM 200N100.1
and PFM 200N200.
Additional standards refer to LV 124 und LV 148:
- BMW GS 95024-2-1 (2010-01)
- BMW GS 95026
- LVA 320: 2014
- Mercedes-Benz MBN LV 124-1
- VW 82148
Another feature of the PFM200N100.1, as well as the PFM 200N200 is a very fast switching time for other
dropout tests such as:
- BMW QV65013
- GMW3172
Finally, we the PFM 200N100.1 and PFM 200N200 fully support switching of BAT- lines for standards that require
it, such as:
- Renault 36-00-808/--M
- Nissan 28401 NDS02

Safety
2.1.
Safety Instructions
In order to guarantee your personal safety, and the safety of personnel in your surroundings, it is
imperative that you read and understand the following safety instructions.
EM TEST devices are related to excess voltage category II.
Symbols on the device
DANGER
Warning of voltages that might involve the risk of electric shock. Pay special attention
to the User’s Guide.
CAUTION
Warns of a possibly dangerous situation. Careful attention should be made to avoid
damage to the device, device under test or its surroundings

Note
Important information about the operation of the device. Carefully read the User’s
Guide.
PE
Protective Earth Connector
Mains Power
The mains power that is used shall not exceed 230V +15% between hot and neutral. The protective earth
connection is made over the power cable and may not, under any circumstances, be removed.
Earthing of the Device and CDN
The device is earthed through the protective earth connection of the mains cable. Therefore, use only mains
sockets where you are sure that the protective earth is correctly used. It is important to verify earthing before
using the device. Any additional CDNs are to be earthed with the provided earth connectors.
Without a proper protective earth, conductive parts of the device may incur dangerous voltages. This may also
affect components that appear to be isolated.
Use Only Tested Mains Cables
Use only the original mains cable or a cable with proper markings to ensure safe operation. Do not use damaged
cables.
Use only Fuses of Specified Type
Solely for use with fuses that meet the specified type found on the mains connector or consult the User’s Guide.
Pay special attention to the type, voltage and current required.
Do not remove covers.
Do not use a device that is open. This is for your safety and the reproducibility of the test results.

Read this guide carefully before putting this device into operation.

2.2.
Care During Testing
All tests using high voltage or EMC generators are immunity tests for electrical devices. The device under test
(DUTs) can react incorrectly which may lead to a dangerous situation. The user is responsible to take care to
avoid the risk to man and material.
One must carefully follow all relevant international guidelines and requirements for the protection of people. This
is especially important in unusual setups or where pulses may be coupled.
People at risk are prohibited from using the system; for example, people with pacemakers.
Long cables leading to the DUT can radiate and effect devices in the area, including devices that do not belong to
the test setup. It is the user’s responsibility to decide if and when the use of an area is acceptable for EMC
testing.
Tests can lead to sparks. It is strictly forbidden to perform tests in areas where there exists a risk of explosion.
While the PFM 200N series produces no dangerous voltages, the very fast switching of inductive loads will result
in large inductive kickback that can be dangerous to life. The output of the PFM 200N is equipped with a GDT
(Gas Discharge Tube) that is designed to suppress voltage over 120V.
2.2.1.
Switching Off
- The generator has limited internal protection.
Switching off of the DUT is accomplished with an electronic switch that contains a current measurement that
can be overloaded to 400 A when the DUT power is switched off.
CAUTION
In extreme cases, like when using an automotive battery into a short, can result in currents well
over 400 A. In these cases, the electronic switch can no longer switch off.
Therefore, additional protection, like an inline fuse, is recommended to ensure safety when using
an automotive battery.
The user must provide a breaker for the DUT. Special adapters with switching and breakers are available, but
must be specified by the user.
- To couple a disturbance on a data or signal line, the coupling method must first be carefully defined.
- If a data or signal line is not to have pulses coupled, the lines shall be removed entirely from the CDN!
2.2.2.
Danger to the Device Under Test (DUT)
The pulses can lead to an unexpected condition of the DUT that results in a dangerous situation.
Therefore, the following conditions should be carefully observed:
•Stop the test when the DUT behaves abnormally.
•Due to an internal defect, high voltage components may make contact to the DUT housing.
•Cables and connectors can be overloaded by overvoltage.
•Internal destruction of components can lead to fire or explosion.
•Accidental operation of the DUT can cause dangerous situations.
DANGER
Never approach a DUT during test!
2.2.3.
Input Capacitance
In order to achieve the necessary switching time, the PFM 200N series contains capacitance at the battery input
PF1. Ripple tests may not be performed when the PFM 200N is connected because the capacitive reactance of
this buffer capacitor will cause the VDS 200Q or VDS 200N to go into current limit. The VDS 200Q series is
prepared with a jumper to easily isolate the PFM 200N when it is not needed. It is strongly recommended to
remove the PFM 200N from the test setup when it is not needed.

PFM 200N Dropout Simulator
The generator serves as the switching unit for dropout testing both power and signal lines required by
various requirements.
5.1.
Switch for DUT Battery Voltage
- Power Switch (S1P) for currents from 100 mA to 100 A (Inrush 400 A for 200 ms)
- Voltage ± 100 V DC
- Switching time < 1 µs (PFM 200N) < 200 ns (PFM 200N100.1 and PFM 200N200)
- Bidirectional switching capability
- Switch (S1N) on the ground line
- Integrated shorting-switch with < 100 mΩ during switch off (S2)
- Additional switchable impedances (R1…Rx), for predefined impedances of the on board power
system
5.2.
Switches for Data and Signal Lines
- Switch (S1 to S16) for currents from 100 µA to 2 A (Inrush 5 A for 200 ms)
- Bidirectional switching capability
- 16 switches for each sign or data lines
- Max. ± 40 VDC
The generator may only be used with AutoWave

Battery Lines
Switch S1 and S2 from the standards LV 124 and LV
148 have a slightly different name in the PFM 200N
Series and its associated software. Switch S2N in the
PFM 200N, used to interrupt the ground line, is not
found in the LV requirements, instead other standards.

Testing according to LV 124 and LV 148 using the autowave.control Software
Tests according to E-10, E-13 and E-14 uses an AutoWave for control. The user must use
AutoWave.control version 5.6.0 or newer.

Locating the Standard Tests for LV 124 and LV 148
LV 124 and LV 148 in the Standards Library
The standards LV 124 and LV 148 are found in
the Standards Library under Automotive –OEM.
Each standard contains various versions.

Selecting a Test
The user may choose the needed version and
test routine. Tests that do not user EM Test
equipment will not be found here. Each test step
is listed individually.
The example in Figure 6.2 the selection of a test:
LV 124(2013-02), E-10 Test Case 1 that includes
a dropout from 100ms to 2s.
Preview
In the right window of AutoWave.control a
preview of the selected test is displayed including
some general information about the selected test.
The picture in the preview window shows the test
run in a simplified way. The user has the
possibility to check the voltage profile of the test
run in a visual way.
