LV 124 Test E-10 short interruption Text case 3
The LV124 is a cooperated standard of all German car manufacturers. The application note AN 213 describes in
detail the tests with E-10 and E-13. The following chapter describes the test using the BS200N100
EM Test proposal for Test case 3 with 0.1
Ω resistor
This proposal is not exact as it is in the LV 124 standard, because the 0.1Ω resistor is only during the interruption
time in the circuit. This disadvantage allows the using of smaller dc sources. It is not necessary to drive a
constant 110A current into the 0.1Ω resistor.

Test setup and cabling
DUT is connected wired with the PFS200 and BS200N100 as shown in figure 7.4.

BNC cable: PFS200 trigger to Trigger IN (BS200N100).
Settings on BS200N100:
Switch Mode: NO Normally Open
Trigger Mode: MAN / Ext.
Duration:
Synchronous with trigger signal PFS200 (Power ON BS200N100 as per note below)
Test:
ON
Power ON BS200N100:
The BS200N100 must work synchronous with the trigger IN signal. For set the
BS200N100 into the LV 124 mode, the user must press the
“Manual Trigger”
button
during connect the power to the BS 200N100. A short LED blinking with an acoustic
beep confirms the correct LV 124 mode. The potentiometer time setting is disabled in
this mode.
Function BS200N100
The Trigger IN controls the ON / OFF position of the
switch. The trigger signal is generated from the PFS200
power fail generator.
