General
1.1.
Purpose
The compact OCS 500Nx generator is a multifunction compact generator that simulates conducted
electromagnetic interference effects for immunity testing to international, national, and manufacturers’standards.
The system is designed for full compliance conducted electromagnetic compatibility (EMC) test requirements.
The application range is for testing of industrial, light industrial, household or commercial equipment, including
many product family and product standards as per following basic standards
Only qualified personnel who deal with attendant hazards in impulse generators, are allowed to perform
installation and servicing. Before put in service the attached safety and user manual must be readed and applied.
The Safety and user manual are an essential part of the equipment and must be available to the operator at all
times. The user must obey all safety instructions and warnings.
It is the user’s responsibility to ensure that the test rig does not emit excessive electromagnetic interference (EMI)
that might affect other equipment. The test system itself does not produce any excessive radiation; however, the
injection of interference pulses into the EUT can result in the device and/or its associated cables radiating EMI.
To avoid radiating unwanted interference the standards organizations recommend that the test setup be located
in a Faraday cage.
1.2.
Safety label on the device
Please take note of the following explanations of the symbols used in order to achieve the optimum benefit from
this manual and to ensure safety during operation of the equipment.
This symbol warns of a potential risk of shock hazard. The symbol on the instrument
shows, that that it can source 1000 volt or more, including the combined effect of
normal and common mode voltages. Use standard safety precautions to avoid
personal contact with these voltages.
This symbol indicates where a caution is required. Refer to the operating instructions
located in the manual in order to protect against personal injury or damage the
equipment
CAUTION
The CAUTION symbol indicates a potential hazard. It calls attention to a procedure,
practice or condition which, if not followed, could possibly cause damage to equipment.
Such damage may invalidate the warranty. If a CAUTION is indicated, do not proceed
until its conditions are fully understood and met.
WARNING
The WARNING symbol indicates a potential hazard. It calls attention to a procedure,
practice or condition which, if not followed, could possibly cause bodily injured or
death. If a WARNING is indicated, do not proceed until its conditions are fully
understood and met.
Attention
Before using this equipment, read the operating manual and the
separate delivered safety manual carefully

1 EUT power mains supply input - Neutral
The neutral N is conducted to the EUT via the coupling/decoupling network to the front panel output N.
2 EUT power mains supply input - Phase
The phase of the power mains supply for the EUT is connected to the lack banana connector L. The 3-phase
device has all power mains supply ports on the lower part at the rear side.
3 SYNC input
Input port for an ac synchronization voltage, to which the events shall be synchronized. If no voltage is available
the tests will start automatically in asynchronous mode. Normally the Sync input shall be connected directly from
the L power mains input (2) of the EUT. The input voltage range is 10 to 250Vac
4 EUT power mains supply input –Protective Earth (PE)
The protective earth PE is conducted directly to the front panel output PE.
5 Reference earth connection PE
The generator must be connected to the reference earth plane of the test set up.
6 Warning lamp
A voltage free contact is available for external warning indications (warning lamp). The relays contact
(250V / 5A) will switch after pressing TEST ON button.
7 Ventilation
After long term duration tests the generator should keep on running for some minutes to cool down the system.
8 Safety circuit
A test can only be started if the safety circuit is closed. By opening the safety circuit during a running test, the
test will be stopped immediately and the high voltage will be switched Off and grounded. For s
The safety circuit will not switch off the EUT Mains supply. For switch off the EUT mains a similar safety circuit
must be used as described in a rack solution in the safety manual.

Using the USB interface the user can have emc problems during EMC tests Our experiences says, that usually
the computer USB port is disturbed by interference’s. Therefore a high quality USB cable (USB 2.0 standard)
must be used.

11 Fast damped output for I/O lines
Coaxial output plug for the fast damped oscillatory wave to a capacitive coupling clamp for testing I/O lines.
12 Direct HV and COM output
The HV and COM output are the designed for an external using of the impulse. This output is floating and is
used for external coupling/decoupling networks or magnetic field antenna.
Attention
The direct HV and COM output of the generator is located at the front panel of the instrument. It
is not allowed to connect these outputs to any other coupling/decoupling network than
manufactured by AMETEK CTS, e.g. the types CNV or CNI.
Before to connect any external networks to this output the operator must contact the
manufacturer. Any damages due to this matter are not covered by warranty.
The direct pulse output shall also not be used to connect the generator directly to any power
conducting lines.

1 EUT power mains supply input - Neutral
The neutral N is conducted to the EUT via the coupling/decoupling network to the front panel output N.
2 EUT power mains supply input - Phase
The phase of the power mains supply for the EUT is connected to the lack banana connector L. The 3-phase
device has all power mains supply ports on the lower part at the rear side.
3 SYNC input
Input port for ac voltage pulse synchronization to the mains. If no voltage is available the tests will start
automatically in asynchronous mode. Normally the Sync input shall be connected directly from the L power
mains input (2) of the EUT. The input voltage range is 10..250 Vac
4 EUT power mains supply input –Protective Earth (PE)
The protective earth PE is conducted directly to the front panel output PE.
5 Reference earth connection
The generator must be connected to the reference earth plane of the test set up.
6 Warning lamp
A voltage free contact is available for external warning indications (warning lamp). The relays contact
(250V / 5A) will switch after pressing TEST ON button.
7 Ventilation
After long term duration tests the generator should keep on running for some minutes to cool down the system.
8 Safety circuit
A test can only be started if the safety circuit is closed. By opening the safety circuit during a running test, the
test will be stopped immediately and the high voltage will be switched off and grounded. For s
The safety circuit will not switch off the EUT Mains supply. For switch off the EUT mains a similar safety circuit
must be used as described in a rack solution in the safety manual.

Description of the menus
The simulator is operated by an easy menu control system. Seven function
keys are available to select parameters and functions. All functions are
indicated on the display; max. 8 lines and 40 characters.
The selected parameter is blinking and can be changed by turning the knob (Inc. /Dec.).
The takeover of the input value occurs after about 500ms encoder downtime. This allows
the operator a brief check of the correct input value.
➔ : The digit to be changed can be selected with the cursor (➔).
- Settled values are direct indicated on the screen.
- Status on the bottom lines shows the desired status after pressing the function
key.
ESC: ESC will take you back to the previous level in the menu and set the displayed
values. The latest settings are stored automatically and will be recalled when the
menu is selected again.
EXIT: The firmware will reset to the main screen.

Phase synchronization in 3-phase system
The built in hardware phase synchronization is between the sync input and PE.
The user must connect the synchronize line L1 with the sync plug.
The synchronization is based on a 3-phase system where neutral is connected to
PE in the supply system.
As Standard line L1 is connected to the sync plug. For coupling other lines, the
OCS500 hardware will not shift the phase angle in relation to the used coupling.
The tables below shows the correction angels considering the phase in a 3-phase system with connected L1 to
the sync input. The user must set the correction angle value manually.
Synchronization: L1 to Sync input
