PV 3 - Measuring equipment BENNING - Free user manual and instructions

USER MANUAL PV 3 BENNING

Please read the detailed operating manual (see section 6.1) before operating the PV tester! This operating manual is intended for qualified technical personnel! Qualified technical personnel is competent to identify risks and to prevent possible hazards. Improper han- dling involves the risk of injury! Always wear personal protective equipment (PPE) when carrying out the test.

Warning of dangerous electric voltage! Absolutely observe all safety instructions!

The connection to the PV generator is made exclusively in accordance with the connection figure of the operating manual. Only use the included PV measuring leads or the measuring leads with attached alligator clips for safe contacting of the PV generator.

The PV generator must be isolated from the electric power supply (PV inverter)!

The PV module/PV string must not exceed the maximum opencircuit voltage of 1500 V DC, the maximum short-circuit current of 40 A and the maximum DC power (P = U x I) of 45 kW. Measuring at PV strings connected in parallel might involve damages of the BENNING PV 3!

Do not disconnect any measuring leads from the PV generator as long as the test is being carried out. Failure to do so might result in a dangerous electric arc or damage to the BENNING PV 3!

The BENNING PV 3 must not be switched off during the test.

are intended exclusively for the connection with PV genera- tors (PV module, PV string, PV field).

WARNING! Be careful when working with bare conductors or main line carrier! Contact with live conductors will cause an electric shock! Remember that work on electrical components of all kinds is dangerous. Even low voltages of 30 V AC and 60 V DC may be dangerous to human life.

Before starting the appliance tester up, always check it for signs of damage. Do not use a damaged BENNING PV 3! Damaged measuring leads must be replaced!

Only use safety measuring leads, which are supplied with the BENNING PV 3.

The included measuring leads are designed for 1500 V systems which are insulated from the main electric supply (PV inverter). Always wear personal protective equipment (PPE) when connecting or disconnecting the measuring leads!01/ 2019 BENNING PV 3

Use the BENNING PV 3 only in compliance with the intended use specified in this docu- mentation. If the BENNING PV 3 is used in a manner not specified by this document then the protection provided by the equipment may be impaired.

Use the BENNING PV 3 under dry ambient conditions only.

Before opening the battery compartment, all measuring leads must be removed! Electrical danger! Before commissioning, the battery compartment must be properly closed.

Do not use pointed objects to remove the rechargeable batteries from the BENNING PV 3. Damaged batteries can leak and increase the risk of fire!

Before the first use and before each use, fully charge the rechargeable batteries. Only use rechargeable 3.7 V 18650 lithium-ion batteries (accumulators, protected version). Unprotected 18650 lithium-ion batteries increase the risk of leakage and damage to the BENNING PV 3.

5.3 Coupling with BENNING SUN 2 (optional accessories)

OFF Remove other electronic devices in direct vicinity. Switch off the BENNING PV 3 and the BENNING SUN 2.

Press and hold both keys of the BENNING SUN 2.

Simultaneously press and hold both keys

of the BENNING PV 3. The BENNING SUN 2 sends a coupling signal with the individual serial number of the device. The BENNING PV 3 stores the signal for future radio connection and signals successful coupling via an acoustic signal and by showing “connected” on the display. The coupling process only takes a few seconds. The "W/m

" symbol is shown on the LC display

5.4 Activating/deactivating the radio transmission of 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 enabled. Note: The automatic switch-off ("APO”) is enabled.

5.5 Measurements on the PV generator

1. Connect the BENNING PV 3 to the PV gen-

erator by means of the included measuring leads.

2. The PV open-circuit voltage is measured auto-

matically if a DC voltage is applied.

3. In case of reversed polarity of the DC voltage,

the polarity indication is flashing and the “ ” symbol is shown on the display

4. As soon as a voltage of > 30 V is applied,

the warning symbol is flashing. Attention! Dangerous voltage

to start the automatic measurement.

6. The measured values will be shown on the

for approx. 20 seconds or until a key is pressed. Note: If the DC voltage is applied with reversed polarity or outside the measuring range (< 5 V or > 1500 V), the measurement is blocked.

5.6 Storing measured values

to store the displayed measured values to the next free storage location. The BENNING PV 3 can store up to 999 display indications. Successful storage will be confirmed by the “STORE” symbol. If there is no more storage location available, an acoustic signal is emitted.01/ 2019 BENNING PV 3
