5.2.5 Starting Automatic RCD Test with RCD
Tripping
The TELARIS RCD Analyzer is equipped with a fully
automatic RCD analysis. As a first step, during a
preliminary test, the contact voltage VC is measu-
red at a current of 40 % I∆N and extrapolated to the
nominal current. Thereafter, various AC residual
currents are generated and both trip time and
contact voltage are verified. The user must only
make sure to switch on RCD after tripping between
the individual test programs. Then, the RCD analy-
sis is automatically continued.
Connect test lead / mains connection cable
to test instrument.
Connect test lead / mains connection cable
to the EUT, as described in figure 1 or 2.
Select desired measurement function (Auto)
using function selection switch (31).
Set nominal residual current selection (20)
to desired nominal current (depending on
RCD).
Select contact voltage using key "VC/UL"
(19).
Touch contact electrode PE (21). Note dis-
play.
If the symbol "Socket Error" (4) appears a PE
error is present.
Press key "Start" (22).
The measurement is interrupted if the contact
voltage exceeds the pre-set contact voltage
limit. The following symbols appear: "Attenti- on (1), "UB>UL" (3) and "Err

I∆N:
.5x
After successful preliminary test the following is
displayed (14):
I∆N:
.5x
"Pr 1" equals 0.5x I∆N 0°, RCD must not trip
"Pr 2" equals 0.5x I∆N 180°, RCD must not trip
"Pr 3" equals 1x I∆N 0°, RCD must trip within
300ms (S-Type 130 ... 500ms)
(test-time 500ms)
"Pr 4" equals 1x I∆N 180°, RCD must trip wit-
hin 300ms (S-Type 130 ...
500ms)
"Pr 5" equals 2x I∆N 0°, RCD must trip within
150ms (S-Type 60 200ms)
"Pr 6" equals 2x I∆N 180°, RCD must trip wit-
hin 150ms (S-Type 60 ... 200ms)
"*Pr 7" equals 5x I∆N 0°, RCD must trip within
40ms (S-Type 50 ...150ms)
"*Pr 8" equals 5x I∆N 180°, RCD must trip wit
hin 40ms (S-Type 50 ... 150ms)
