Short Instructions
BENNING PV 1-1+
Important information
m
Before using the BENNING PV 1-1+ please read the detailed
operating manual (http://tms.benning.de/pv1-1) carefully. The
BENNING PV 1-1+ should only be used by suitably trained
personnel.
c
The connection to the PV generator is made exclusively in accord-
ance with the connection figure of the operating manual.
Disconnect not required measuring lines from the BENNING PV 1-1+.
c
Before the measurement disconnect the PV generator from the
PV inverter!
The PV generator under test must not exceed the maximum open-
circuit voltage of 1000 V, the maximum short-circuit current of
15 A and the maximum DC power (P = Uoc x Isc) of 10 kW.
The measurements are to be carried out on the individual PV string!
It must be ensured that all switching devices and isolating devices
are open and that all PV strings are isolated from each other.
Only test a single PV string, never test multiple strings and beware
of parallel connections! High levels of capacitance within the circuit
under test can cause high currents to flow and may damage the test
instrument.
The PV generator may not contain any power optimisers. In the
event of a short circuit, power optimisers can generate transient
current peaks that significantly exceed the specified short-circuit
current (Isc) of the PV generator.
Non-observiance will result in damage to the BENNING PV 1-1+!
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.
Measured value memory (200 display screens)
-Store
Store all measurements currently on the LC display. In the RE-
CALL mode, the measuring results are called in reverse order.
-Recall
Recall the stored measured values on the LC display.

Setting the date and time
1. Turn off the BENNING PV 1-1+.
2. Press and hold the
-
key and then press simultaneously the
R
PE
-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
PE
-key to select a date field and time field
5. A blinking field shows that this field can be set.
6. With the -key and the
-
key, the value increases or decreases. With
each change, the second field is set to zero.
7. Turn off the device to save the setting.
Note:
If the BENNING PV 1-1+ has established a radio connection to the BENNING
SUN 2, the date/ time of the BENNING PV 1-1+ will be synchronized
automatically after 10 seconds to the date/ time of the BENNING SUN 2, if the
device detects a deviation of more than 1 minute. BENNING SUN 2 (master) →
BENNING PV 1-1+ (slave).
Setting the Auto Power Off (APO, Auto-Power Off)
1. Turn off the BENNING PV 1-1+.
2.
5. Then release the
Ω
NULL
-key to save the setting.
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.

2.
Couple the BENNING PV 1-1+ with the BENNING SUN 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.
4.
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+.
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+.
