RCD Type AC Selective (Sinusoidal Waveform)
RCD Type A (Pulsating Waveform)
RCD Type A Selective (Pulsating Waveform)
RCD Type B (DC)
During selective tests, the DL9120 / DL9130EV will display a delay timer
which counts down from 30s to 0s. Pressing the Test key or turning the
rotary switch while the DL9120 / DL9130EV is counting will terminate the
count.
Increase Test Current (F4)
Increases the test current displaying the secondary display.
Decrease Test Current (F4)
Decreases the test current displaying the secondary display.
TEST
To start a test, press the TEST key, the test will be performed and the trip
current of the RCD will be displayed in the primary display.
5.13 RCD trip current (Ramp) Tests
The DL9120 / DL9130EV will only allow the RCD test to be
performed if the correct voltages are detected between line-
earth (L-PE illuminated), line-neutral (L-N illuminated) and
neutral-earth (N-PE
not
illuminated).
Potential fields from other earthing installations, large
voltages between the protective conductor and earth, large
voltage between the neutral and earth or leakage currents
in the circuit following the residual current protection device
may influence the measurement.
Equipment which is connected downstream of a residual
current protective device (RCD) may cause a considerable
extension of the operating time.
The DL9120 / DL9130EV will determine the fault voltage
that may appear on the protective conductor during the test.
If the fault voltage is greater than 25V the DL9130EV will
