Test 6

Test of RCD Type B of the EVSE system
82. Connect the instrument to the adapter as shown in the
diagram on the display (input B4 to input N , input B3 to
input E and input B1 to input L1 ). Use the three
selectors of the adapter and set the following
positions:
 PP State  13A,20A,32A or 63A
 CP State  C
 Fault  OK
RCD 15/10 – 18:04
6/6 – B Type RCD Ramp test
83. This test is carried out by the instrument by
only
considering standard STD (G) RCDs, of type B and in
Ramp mode ( ) 0° ( +), no display of contact voltage
Ut, rated current selectable among the following
values: 6,10,30,100,300,500,650mA
. Please refer to §
Errore. L'origine riferimento non è stata trovata. for a
description of the setting of the test parameters.
Notice the presence of the correct voltage values
between L-PE and L-N as shown in the screen on the
side.

Press the GO/STOP key. The instrument will start
measuring and the display will show the message
“ Measuring …” . During this whole stage, do not
disconnect the test leads of the instrument from the
system being tested. The following screen appears on
the display:
When the RCD trips and breaks the circuit, in case the
tripping time and the tripping current are within the limits
reported in § 12.4, the instrument gives out a double
acoustic signal which indicates the display of the
message “
OK ” and of the screen to the side.
