7)
READY message will appear when mains voltage U
L/N
(LOOP L/N) or U
L/PE
(LOOP L/PE) within
100
265 V or U
L/L
(LOOP L/L) within 100
460 V is present. Carry out the measurement by
pressing the
START
button.
8)
Test result (loop impedance) will be displayed in green colour equipped with green
symbol and
with beep-beep sound if measured/calculated I
SC
corresponds to entered limit mode and other
entered parameters. If measured/calculated I
SC
does not correspond to entered limit mode and
other entered parameters the result will be displayed in red colour equipped with red
symbol
and with longer beep sound. See the display outlook with test result on the figure 22.
9)
Save the test result by pressing the
SAVE
hard button twice, for further instructions see the
“MEMORIZING EXAMPLE” section.
10)
Press the
EXIT
hard key to clear displayed result, actual input voltage U
L/L
or U
L/N
or U
L/PE
will
start to be displayed again.
CAUTION
In case voltage U
L/N
(LOOP L/N measurement) or voltage U
L/PE
(LOOP L/PE
measurement) within required range 100
265 V is present at L/N/PE test
terminals (also displayed) but there is no READY message displayed, check if
energizing socket is correctly earthed!
In case voltage U
L/L
(LOOP L/L measurement) within required range 100
460
V is present at L/N test terminals (also displayed) but there is no READY
message displayed, check if energizing socket is correctly earthed!
If limit
mode STD is
selected (result is not evaluated), then the result will be
displayed in white colour.
The following specific information can be shown on the display during the measurement:
Information displayed
Description
VOLTAGE OUT OF RANGE
Input voltage U
L/N
or U
L/PE
out of required range 100
265 V (L/N or L/PE measurement) or out of required range
173
460 V (L/L measurement) after pressing the START
key.
FUSE F3!
Fuse F3 is blown.
HOT!
Internal load is overheated.
Wait to cool it down!
MEASUREMENT FAILED!
Input voltage failed during the measurement (disconnection
of test leads, installation fuse tripped etc.)
5.7. GLOBAL EARTH RESISTANCE / CONTACT VOLTAGE (RA)
• According to EN 60204-1, the conditions for protection against electric shock in installations with
automatic disconnection of mains voltage are:
• Measurement or evaluation of fault loop impedance and testing the over-current protection device
involved in the fault loop.
• Limit values are shown in the Table 10 of EN 60204-1.
