Standards covered by RCB 200N1

specified in the normative Annex E of the Ford EMC-CS-2009.

1.1.

General

The RCB200N1 is an impulse generator who generates burst pulses using mechanical contacts. The pulses are

generated by opening and closing the relays contacts (RLY1). Therefore the amplitude and waveform are

random generated by the relays contact.

The randomness is additionally influenced by the choice of modes. With the pulse selection, the tendency of

amplitude and wave shape will be influenced. This is done by different attenuation of the pulse generator and the

tap at different locations in the circuit.

The DUT is connected internally depending on the pulse selection at different points in the circuit.

The RCB have been tested and approved by Ford Motor Company and found to be acceptable for use when

performing EMC testing per EMC-CS-2009.

Operation

3.1.

Power supply

The Box is powered from the BAT input13.0V (+0.5V / -1.0V). The power supply to the DUT is fused with the 20A

Fuse on the front panel.

The electronic is equipped with a reverse battery protection and will switch off automatically at approx. 18.5V

overvoltage, for protect the internal parts from overload.

3.2.

Test ON button

CI220 test

For CI 220 tests the TEST ON button will switch on the power to the DUT output

plugs.

Press the button again will finish the test (SEQUENCE or ENDLESS) automatically

and will return to STOP status.

RI 130 tests

During this test no DUT is connected to the DUT output plugs.

Therefore the TEST ON is inactive.

CI 260 tests

During this test DUTsupply voltage is switched as part of the test.

Therefore TEST ON is inactive.

3.3.

ID, PULSE and MODE settings

The edit of the following functions is only in STOP mode possible.

With pressing the button the LED display increments to the next setting. A cyclic rotation indicates all possible

settings of the selected test.

3.3.1.

Identity of the used test according Ford EMC-CS-2009 standard

RI 130 : Coupled Immunity

CI 220 : Immunity from Transient Disturbances

CI 260 : Immunity to Voltage Dropout

3.3.2.

PULSE

According to the selected ID, different Pulses are available.

Pulse application depends on the selected ID. The RCB 200N1 offers only the pulse

applications, defined in the selected ID. The following pulse are offered:

CI 220: A1, A2-1, A2-1 & C-1 (Mode 2 / 3), A2-2 & C-2

CI 260: F

A2-1 & C-1: M2, M3

A2-2 & C-2: M2, M3

RI 130 A2-1: M2, M3

A2-2: M2, M3

Mode 1

Represents a condition where the test pulse is

applied at a repetition rate of 0.2 Hz with 10% duty

cycle and 120s duration.

Figure 3.1 : Mode 1

Mode 2

Represents a condition where test pulses are

applied using pseudorandom timing sequences.

The time T is 50ms.

Figure 3.2 : Mode 2

Mode 3

Represents a condition where test pulses are

applied using pseudo- random bursts. The timing

sequence is identical as used for Mode 2.

3.4.

START / STOP

With the START / STOP button the user starts and stops the test sequence. The

release of the Start button will automatically release the TEST ON function and starts

the test directly.

During running a test the following LED indicates:

LED Sequence : Test is running and stops after the test duration

LED Endless: Test is endless running. Stop with Stop button

Power on DUT

Depends on the status of the power before the test start, the voltage will be switched

off after the test. Figure 3.4 illustrate the procedure of the power on handling after

the test.

3.4.1.

Sequence

The Sequence is the normal procedure for testing any DUT according the standard.

START: Press START/STOP button for begin a test sequence

STOP: Press START/STOP button for terminate at anytime a test sequence.

After pressing the START button, the test sequence will start. The LED Sequence is illuminated and indicates the

running test. At the test end the generator returns automatically into STOP mode.

The SEQUENCE duration is defined by the Ford standard for each PULSE and MODE.

The RCB200N1 offers an option for endless testing. This can be used for long duration tests during the

development or internal quality tests.

START: Press START/STOP button during about 2s till the LED Endless illuminates.

STOP: Press START/STOP button for terminate at anytime an endless test sequence.

Application with EXTERNAL trigger signal will set the RCB200N1 automatically in “ENDLESS” mode

3.4.3.

Stop

For stop a test the user has the following options:

START / STOP button: Stops the test and the supply voltage keeps at the DUT output terminal.

In case when the TEST ON was not enabled at the test start, the DUT supply voltage will

automatically switch off.

TEST ON button: Stops the test and switches off the DUT supply voltage.

TEST OFF will stop anytime a running test and interrupt also the DUT supply voltage.

3.5.

Trigger Internal - External

The RCB 200N1 offers an internal Trigger generator for the

pulse timing. The user is free to connect his own trigger

generator for drive the Relays. The trigger input

corresponds to the input E as per Ford EMC-CS 2009

Figure F-1.

Figure 3.5 shows the two methods and connection for

generate the trigger signal for RCB200N1 trigger.

A Internal Trigger: Using the binternal trigger generator

with a bridge from Trigger OUT to

Trigger IN BNC plug.

B External Trigger:Using an external and user

programmed trigger generator device,

connected direct to the Trigger IN BNC

plug.

Figure 3.5 : Block diagram of RCB 200N1 trigger

Internal Trigger

Figure 3.6: Internal trigger

Function: Using the internal trigger, the controller sense automatically the bridge

connection from Trigger OUT to Trigger IN. The internal processor will

generate the trigger signal for relays release.

Note: Internal/External trigger detection happens with a periodic pulse train

of three short pulses (<1µs) in the trigger out signal during stop

status. When these “Phantom pulses” are received at the trigger in

side, the controller detect internal Trigger. Otherwise the Ext Trigger

LED appears.

External Trigger

Figure 3.7: External trigger

Function: An external arbitrary generator can be used for generate the trigger

signal for relays release. The input is enabled after pressing the

START/STOP button. The relays can be controlled after TEST ON or

START button.

The LED Ext. Trigger Mode indicates the disconnected internal

trigger bridge.

Remark: Lifetime is only incremented if RCB 200N1 is switched to Start in

ENDLESS Mode.
