Introduction These operating instructions contain information and directions which are necessary for safe operation and use of the instrument. Before using the instrument, the operating instructions must be carefully read and all points contained therein must be followed correctly. Non-observance of the operating instructions, as well as warnings and directions included therein, may result in severe injury to the user or damage to the instrument.
8 Initial Start-Up The PROFITEST PVSUN is supplied with power from four AA batteries (1.5 V IEC LR6). The batteries must be inserted before the instrument can be used. ➭ Remove the battery compartment lid on the back of the instrument by loosening the two Phillips head screws. ➭ Insert the batteries. Be sure to observe the polarity symbols which are embossed into the floor of the battery compartment. ➭ Replace the battery compartment lid and retighten the screws.
➭ Switch the PROFITEST PVSUN test instrument on. The module’s open circuit voltage U0 appears at the display. Example Warning! Disconnect the solar module under test from the system before performing measurement. U0: 995 V ISC: --RISO: --Note In the case of incorrect polarity, a warning symbol appears to the right of the voltage display. Example U0: Pol ISC: --RISO: --- ! ! Attention! Insulation measurement per EN 62446 is executed between short circuited (+) / (–) and () terminals.
Minimum Permissible Limit Values for Insulation Resistance Relative to Insulation Test Voltage per EN 62446 System Voltage (U0 x 1.25) Test Voltage Limit Value < 120 V 250 V 0.5 M 120 to 500 V 500 V 1 M > 500 V 1000 V 1 M Note If the limit value is fallen short of, < 1 M or < 0.5 M appears for RISO. Example Example U0: 0 V ISC: 0.0 A RISO: --Uiso = 1000 V Executing the Insulation Resistance Measurement ➭ Press the RISO/250V/500V/1000V key and read the measured value from the display.
10 Data Storage with PROFITEST PVSUN MEMO The PROFITEST PVSUN MEMO test instrument is equipped with an internal memory for the storage of 10,240 data records. The stored data can be read out via a USB port for subsequent evaluation from a PC. Furthermore, the included PC software allows for the creation of individual test structures. 10.
11 Application of PC Software Individual test structures can be created at the PC with the included software. This structure makes it possible to assign measurements to the objectes and strings of different units and buildings. For use at the construction site, the respective test structures are first transferred to the test instrument via the USB interface.
12 Measurement of irradiation, temperature and inclination with PROFITEST PVSUN-SOR (optional) Warning! Hot surfaces may cause burns. Insulation Resistance Measurement RISO Test voltage 250 V DC Measuring range 0.5 Mto 1 M 1 M to 20 M 1 M to 20 M Resolution 0.1 M 1 M Accuracy (1% rdg. + 1 d) (1% rdg. + 2 d) (1% rdg. + 2 d) Limit value > 0.5 M > 1 M > 1 M No. of measurements 500 V DC 1000 V DC 1 M Approx.
14 Maintenance 14.1 Battery Replacement 15 If the battery level indicator displays only minimal remaining battery capacity (only one segment appears, see figure at right), the batteries must be replaced. ➭ Switch the instrument off and disconnect it from all measuring circuits. ➭ Remove the battery compartment lid on the back of the instrument by loosening the two Phillips head screws. ➭ Remove the depleted batteries. ➭ Insert new batteries.
