Short Instructions
BENNING PV 1-1
Important information
m
Before using the BENNING PV 1-1 please read the detailed operat-
ing manual (CD-ROM) carefully.
The BENNING PV 1-1 should only be used by suitably trained per-
sonnel.
c
The connection to the PV generator is made exclusively in accord-
ance with the connection figure of the operating manual.
Disconnect not required safety tests leads from the BENNING PV 1-1.
c
The PV module/PV string must not exceed the maximum open-
circuit voltage of 1000 V DC, the maximum short-circuit current of
15 A and the maximum DC power (P = U x I) of 10 kW.
According to DIN EN 62446, the measurements have to be made for
each PV string.
Measurements made at PV strings which are connected in parallel
might involve an overload of the BENNING PV 1-1.
c
Disconnect the BENNING PV 1-1 from the test sample directly after
the test.
c
Do not touch the measuring probes! During insulating resistance
measurements, high electric currents might be applied to the meas-
uring probes.
c
Do not touch any metal parts of the test object during measure-
ment.
c
The PV generator must be isolated from the electric power supply!
Neither the positive nor the negative pole of the PV generator must
be earthed!
c
Via the 4 mm safety test leads, voltage measurements on mains
supply circuits are possible. Via the 4 mm test sockets, the
BENNING PV 1-1 must be used only in electric circuits of overvolt-
age category III with max. 300 V AC/DC for phase-to-earth measure-
ments. For this please disconnect the PV 1-1 measuring leads from
the PV test sockets before measuring.
c
Before starting the unit, always check it for signs of damage. Do not
use a damaged BENNING PV 1-1!
m
Only use safety measuring leads, which are supplied with the
BENNING PV 1-1.
c
The BENNING PV 1-1 is intended for making measurements under
dry ambient conditions only.

-key and
the
Auto
-key of BENNING PV 1-1.
3. The date format and time format is shown as follows:
MM.DD = month (1-12). Day (1-31)
YYYY = year
HH.mm = hours (0-23).minutes (0-59)
SS = seconds (0-59)
4. Press the
R

Radio connection to BENNING SUN 2 - wireless SUN link
The BENNING PV 1-1 is able to receive the measured values (insolation, PV mo
-
dule/ambient temperature and date/time stamp) of the insolation and temperature
measuring instrument BENNING SUN 2 (optional) via radio connection. For this
purpose, the BENNING PV 1-1 has to be coupled with the BENNING SUN 2 once.
Typical radio range of the BENNING SUN 2 in open space: approx. 30 m
Buildings/metal structures or interfering signals can reduce the radio range.
Coupling with insolation/temperature measuring instrument BENNING SUN 2
1. Remove all electronic devices in direct vicinity
2. Switch the BENNING PV 1-1 and the BENNING SUN 2 off.
3. Press and hold the two ON/OFF keys of the BENNING SUN 2.
4. Press and simultaneously hold the
R
PE
-key and the
Auto
-key of the
BENNING PV 1-1.
5. The BENNING PV 1-1 indicates the successful coupling by means of an
acoustic signal and by displaying the serial no. of the BENNING SUN 2
6. The "W/m
2
" symbol is shown on the LC display of the BENNING PV 1-1.
Decoupling from insolation/temperature measuring instrument BENNING SUN 2
1. Remove all electronic devices in direct vicinity.
2. Switch the BENNING PV 1-1 off.
3. Press and hold the
R
PE
-key and the
Auto
-key of the BENNING PV 1-1 for approx.
10 seconds.
4. The BENNING PV 1-1 indicates the decoupling from the BENNING SUN 2 by
means of an acoustic signal and by clearing the LC display.
5. The "R
PE
/Ω" symbol is shown on the LC display of the BENNING PV 1-1.
Activating/deactivating the radio transmission of the BENNING SUN 2
1. Couple the BENNING PV 1-1 with the BENNING SUN 2.
2. To activate/deactivate the radio transmission, press and hold the
-key of
the BENNING SUN 2 and simultaneously press the
-key. A flashing triangle
above the
-key shows that the radio transmission has been activated.
3. If the BENNING PV 1-1 is within the radio range of the BENNING SUN 2,
the measured insolation value (W/m
2
) is shown on the LC display of the
BENNING PV 1-1.
4.
Besides the electric variables (Vo/c, Is/c, R
ISO
), AUTO measurement by means
of the BENNING PV 1-1 additionally measures the insolation, the module and
ambient temperature as well as the date/time stamp of the BENNING SUN 2.
5. If the BENNING PV 1-1 is outside the radio range of the BENNING SUN 2, the
"W/m
2
" on the LC display starts flashing. Moreover, "_ _ _ _" is shown on the
LC display, if the measured insolation value is outside the measuring range.
Note:
If the BENNING PV 1-1 does not receive any radio signal from the BENNING SUN 2,
the display indications are stored with the date/time stamp of the BENNING PV 1-1.
