14.10.4 Test Sequence PRCD-S (three-phase) – 18 Test Steps
Selection Examples
Simulation Interruption (Steps 1 to 10)
Simulation Conductor Exchange (Steps 11 to 16)
Simulation PE to Phase (Step 17)
Measurement of Protective Conductor Current with Current Clamp
Transformer (Step 18)
Semi-automatic Change of Fault Simulations (Statuses)
As an alternative to changing
manually between the fault sim-
ulations via the parameter menu
of the respective PRCD selec-
tion PRCD-S 1~, PRCD-K 1~ or
PRCD-S 3~ at the test instru-
ment, it is possible to switch
quickly and conveniently
between the fault simulations.
Select status parameter AUTO
for this purpose. After replying
to and storing each visual
inspection, an automatic
switch-over to the next fault simulation takes place. Individual fault
simulations can be skipped by pressing key I
ΔN
at the test instru-
ment or at the test plug.
15 Automatic Test Sequences – AUTO Function
Selecting Switch Position AUTO at the Test Instrument
When the rotary switch is set to AUTO, all existing test sequenes
in the instrument are displayed, see Figure 15.4.
If there are no test sequences in the instrument, message „NO
DATA“ appears.
15.1 General
Layout of the Test Sequences
If the same order of tests with subsequent report generation is to
be performed repeatedly, as is, for example, specified by certain
standards, we recommend using test sequences.
With the help of test sequences it is possible to compile auto-
matic test procedures on the basis of the manual individual mea-
surements. A test sequence consists of up to 200 individual test
steps which have to be processed one after the other.
Basically, a distinction is made between three types of individual
steps:
• Note (“visual Inspection” test step): the test procedure is inter-
rupted by a pop-up note for the test engineer. It is not contin-
ued before the test engineer acknowledges the note.
Example: Note prior to insulation resistance measurement:
„Disconnect the device from the mains!“
• Visual inspection, testing and report: the test procedure is inter-
rupted by a pop-up window of a passed/failed evaluation,
comments on and results of the evaluation are saved in the
database.
• Measurement (“user-evaluated measurement” test step): Measure-
ment like the individual measurements performed by the test
instruments with data storage and parameter configuration.
Creating Test Sequences with IZYTRONIQ
As of PROFITEST MASTER firmware version 1.7.0, test sequences
are created at a PC with the help of the included IZYTRONIQ soft-
ware, and are then transferred to test instrument. Any number of
test sequences can be created and stored at the PC in IZYTRONIQ.
Up to 10 selected test sequences can be transferred to the test
instrument.
No option for transferring test sequences from the test instrument
back to the PC has been provided for because sequences can
only be created, managed and stored at a PC.
General instructions regarding the creation of test sequences can
be found in the online help provided with IZYTRONIQ.
