Safety advice
All accessories are intended for use with the Modula 6100 generator type. This generator produces high
voltage test pulses that have high energy. Therefore improper or careless handling can be fatal!
These operating instructions form an integral part of the equipment and must be available to the operating
personnel at all times. All the safety instructions and advice notes are to be observed.
Keeping responsibility to the instructions and recommendations that follow is imperative.
The safety advice referring to the generators also applies and must be complied with when using the
instruments together with all accessories.
Neither Schaffner EMV AG, Luterbach/Switzerland nor any of the associated sales organisations accept
any responsibility for personal injury or for material or consequential damage that results through
irresponsible or negligent operation of this equipment.
Safety measures
These operating instructions form an integral part of the instrument and must be studied carefully before
putting the device into use as well as being available at all times to the operating personnel.
The instrument must only be used by trained personnel.
Persons fitted with a heart pacemaker must not operate the instrument and should not be in the vicinity of
the test rig when pulses are triggered.
Arrange the working area in compliance with appropriate safety standards (e.g. VDE 104).
Connect an additional earth wire to the rear panel of the generator and to the coupling network.
The test rig must provide adequate insulation protection for up to 4.8kV. Particular care should be given to
the connections between the accessories and the equipment under test (EUT).
The EUT may only be tested when placed inside a suitable protective enclosure which should provide
protection against flying fragments, fire and electric shock.
The pulse voltage must not be able to find its way to unearthed metal objects in the event of the EUT
failing.
Only use the instrument in a dry room. Never leave the instrument unattended when it is switched on.
Do not open the instrument. Repairs and adjustments must only be carried out by qualified maintenance
personnel.

1 Manual step transformer INA 6501
The step transformer type INA 6501 is a standard accessory for the Schaffner Modula 6100 instru-
mentation series. It provides a convenient means for reducing the incoming supply voltage by pre-set
amounts. It is required for power quality testing (PQT) and is fully compliant with the latest revisions of IEC
61000-4-11:2004.
It is fitted with carrying handles as part of its overall good ergonomic design, which makes for ease of
handling. Further, the unit may be used in any of three operating positions; laying or standing on a work
bench, or for more permanent applications, it can be wall-mounted.
Care has to be taken in case of use in standing position, as the stability is
limited. The cabling connecting INA 6501 to mains and Modula presents a risk
of being unvoluntarly caught by the users which could cause the INA 6501 to
fall down.
The few control elements are readily accessible on the front panel. An EUT power on/off switch with a
power on indicator and a well-proportioned rotary switch to select the required voltage ensure easy and
intuitive operation.The unit has been designed for use in rugged industrial environments. Professional
quality connectors ensure user safety, additional system protection is provided by a 16A fuse located in the
front panel.
Thanks to the provision of an 80% voltage position and to the large overcurrent capabilities the step
transformer is fully compliant with the latest requirements called for in IEC 61000-4-11: 2004 standard.

Because of the capacitors in the internal coupler of Modula CDN 6501, earth leakage
currents of up to 4A can occur in the EUT power supply network. The test system
must therefore be correctly earthed and be powered from a supply that is not
protected by a residual current detector (RCD).

2 Automatic step transformer INA 6502
The step transformer type INA 6502 is a standard accessory for the Schaffner Modula 6100
instrumentation series. It provides a convenient means of reducing the incoming supply voltage by pre-set
amounts. It is required for power quality testing (PQT) and is fully compliant with the latest revision of IEC
61000-4-11 (2004).
Its control is fully automatic, driven from Modula master controller, using the mobile hand-held controller
MHC 6550 or WIN Modula software. Once detected by the Modula master controller and declared to the
driving software ModPDA or WIN Modula, the functions offered by INA 6502 are available in the software.
So the settings 0% - 40% - 70% - 80% will appear, as well as the possibility to switch EUT power on/off in
case an external switch (e.g. option INA 6581) is connectd to the circuit breaker option CIB is fitted in the
INA 6502.
INA 6502 comes fitted with carrying handles as part of it’s overall good ergonomic design, which makes for
ease of handling. Further, the unit may be used in any of two operating positions; laying on a work bench,
or for more permanent applications, it can be wall-mounted.
The unit has been designed for use in rugged industrial environments. Professional quality connectors
ensure user safety, additional system protection is provided by a 16A fuse located in the top panel.
Thanks to the provision of an 80% voltage position and to the large over current capabilities the step
transformer is fully compliant with the latest requirements called for in IEC 61000-4-11:2004 standard.
For proper operation of the plug and play detection mechanisms it is
strongly recommended to power on first the INA 6502 accessory and then
the Modula 6100 main frame. Powering on the Modula main frame before
the accessories may result in non-detection of accessories.

2.4 HW Detection
The INA 6502 is automatically detected by the Modula firmware during
the booting process. Its presence is visualised in ModPDA settings
screen as PQT – supply.
In case several PQT sources (INA 6502 – VAR 6501 – etc.) are
connected on the system bus and get detected by the modula firmware,
it will be up to the user to tell the software which source is actually used.
This can be done by clicking the field indicating PQT – supply, the
various detected possibilities will scroll through.
2.4.1 Operation
The parameter Uvar gets active once an INA 6502 has been detected by
the software. The entry of Uin is by default 230V and may be set to other
voltages. Uvar consist one of the 4 available variable voltage levels: 0% -
40% - 70% - 80% and can be selected by the user by acting on the up or
down arrow key.
Selecting “T Event” or “Rep.Rate” and stay on the unit (e.g. s, ms, a.s.o)
then the unit will change for an easier time seting

3 Automatic variable transformer VAR 6501
The automatic variable transformer type VAR 6501 is a standard accessory for the Schaffner Modula 6100
instrumentation series. It provides a convenient means for reducing the incoming supply voltage by
adjusting the incoming EUT supply voltage to arbitrary voltages. It is required for power quality testing
(PQT) and is compliant with the latest revision of IEC 61000-4-11 (2004).
Its control is fully automatic, driven from Modula master controller, using the mobile hand-held controller
MHC 6550 or WIN Modula software. Once detected by the Modula master controller and declared to the
driving software ModPDA or WIN Modula, the functions offered by VAR 6501 are available in the software.
So the settings of Uvar will be possible in Volts or % of Uin, as well as the possibility to switch EUT power
on/off in case an external switch (e.g. option INA 6581) is connected to the VAR 6501.
It is fitted with carrying handles as part of its overall good ergonomic design, which makes for ease of
handling. Further, the unit may be used in any of two operating positions; laying on a work bench, or for
more permanent applications, it can be wallmounted.
The unit has been designed for use in rugged industrial environments. Professional quality connectors
ensure user safety, additional system protection is provided by an 8A fuse located in the top panel.
For proper operation of the plug and play detection mechanisms it is strongly
recommended to power on first the VAR 6501 accessory and then the Modula 6100

in a non detection of the accessories.
