4.5 Voltage Test (option: PROFITEST 204HP/HV)
Electrical equipment at machinery must withstand a test voltage
applied between the conductors of all electrical circuits and the
protective conductor circuit for a period of at least 1 second, with
a value of twice the rated voltage of the equipment or 1000 V~,
whichever is greater. The test voltage must have a frequency of
50 Hz and must be generated by a transformer with a minimum
power rating of 500 VA.
Note
The PROFITEST 204+ must be used in combination with
the PROFITEST 204HP/HP-2.5kV high-voltage module
for testing in accordance with DIN VDE 0113.
The PROFITEST 204HV/HV-5.4kV is required for testing
with up to 5 kV.
The
PROFITEST 204+
automatically recognizes which type of
high-voltage module has been connected. Communication
between the basic instrument and the high-voltage module can
be tested as described in chapter 3.7.4.
!
Attention!
Inspect the test instrument, high voltage cables and
high-voltage pistols to assure flawless condition before
beginning work (see also chapter 11.4, page 67).
Note
Testing of measurement cables
The first test should be conducted on test probes with
short-circuited measurement cables. The instrument
must indicate a value of approximately zero

. This
serves to establish whether the measurement cables are
disconnected at any point.
4.5.1 Functions Test (test preparation)
Perform the following functions test in the indicated order from a)
through e).
a) Key Switch
➭
Set the key switch to “0”.
• Neither the green nor the red signal lamps may light up.
b) Voltage Test
➭
Set the key switch to “I”.
• The green signal lamps must light up.
➭
Select the voltage test with the keys.
TEST
Select the desired test.
Initialisation of high-voltage module
as a prerequisite for correct parameter input
➭
Press the START key.
The corresponding high-voltage module is recognized and dis-
played in the bottom left corner of the LCD provided it has been
correctly connected and the key switch is in the „I“ position.
The initialisation ensures that the parameter values that are sub-
sequently entered are within the limits applicable to the respective
high-voltage module.
