Maintenance setup and service
7.1.
General
The generator is absolutely maintenance-free by using a solid state semiconductor switch to generate transients
7.2.
Test set- up
When setting up the test national and international regulations
regarding human safety have to be guaranteed.
It is recommended to connect the simulator to the ground reference
plane of the test set-up.
The generators of the series 500, UCS, VCS, CSS, TSS and CNI, can
be linked together to a fully automotive test set-up.
The set-up communicates via the IEEE / GPIB bus and is controlled by
software. For setting up the system see the following figures:
Each generator can be operated individual as a single equipment.
7.3.
Fuse for the EUT power supply
The EM Test pulse generators have no built in fuse for the EUT power supply. It is in the scope of responsibility
of the user to protect the EUT external for the rated current.
The design of the external fuse must be match the following rules:
- fuse dimension must be
equal or
smaller
than the
rated EUT current
of the connected
test
generator
- fuse must be designed for
protect the connected EUT
device under test in malfunction
Example of external fuse
Fuse in the building is designed for
32A. A Fuse box with 16A fuse
protection is installed between the
building supply and the test
generator.
Test generator and EUT are now
fused for 16A rated current
Example
16A protection with a 100A
installation with a 3-phase fuse box.
The user has protected his
Equipment Under Test with this
additional fuse box for a rated current
of 16A.
7.4.
Insulating- or external transformer for EUT power supply
The recommended power of an external transformer must be
> 500VA
. The reason is the
capacitive current of the internal filter capacitors inside the UCS 500N5 / N7.
