When the required settings have been selected, press the TEST key to
begin the sequence.
Note: The DL9110 / DL9118 will determine the fault voltage that
may appear on the protective conductor during the test. If
the fault voltage is greater than 25V the DL9110 / DL9118 will
indicate >25V on
the LCD, but the user may proceed with the
test. If the fault voltage is great than 50V, this is indicated on
the LCD and the test is inhibited.
If the fault voltage is less than 50V the test sequence will proceed and
the trip times are shown in the primary display. The fault voltage is
measured and not calculated.
When the sequence is completed, the RCL key (F3) is used to recall the
measurements.
5.11 RCD Trip Time Tests
The DL9110 / DL9118 will only allow the Earth Loop
Impedance test to be performed if the correct voltages
are detected between phase-neutral (PN illuminated),
phase-earth (PE illuminated) and neutral-earth (NE
not
illuminated).
Leakage currents in the circuit following the residual
current
protection
device
may
influence
the
measurement.
