The Sollatek Three Phase Automatic Voltage Regulator (AVR) www.s ol la tek . c om Instruction Manual Issue: July 2021 Important: This manual contains important safety instructions.
The unit should be positioned such that a free flow of air is available. It is especially important to Trouble Shooting ensure that cooling fan outlets are free from obstruction. A free space of at least 300mm should be Safety left in all directions around the AVR. False Starting Shut Down Cable and terminals...
See diagram 2.6.1 the door of the AVR should indicate a valid output voltage. If this is not the case switch off the power immediately and refer to the troubleshooting section of this manual. The AVS indicators on the door (if Outgoing connections fitted) should show ‘on’...
21kVA. The parameters monitored by the Three Phase AVS are: The standard Three Phase AVR provides an output which is stable to within + 4% given an input a) Value of the Mains Voltage voltage variation of + 27% from a defined nominal. Although it is likely that voltage stability of + 4% The normal condition is when the values of the mains voltage of all the phases are within certain will meet most customers’...
This ensures that the supply to the AVR cannot be re-connected unintentionally by component failure If it is found that the AVR keeps trying to start but turns off immediately, this is most likely to be due or supply disruptions. This is particularly important if the bypass is used to enable maintenance to be to poor wiring to the AVR or in the building.

AVS delay setting _______________________________________ 20% full load. AVS must be operational for this test. 11. Connect two phases to the input of the AVR. Connect the third phase via the variac. Adjust the variac voltage Inspected by (SUKL Engineer) _______________________________________ to 230V.

Ensure the AVR is isolated from the supply and load before commencing 1. On certain AVR models it will be necessary to remove the rear panel to access the AVS PCB. 2. Note all wiring colours and positions and AVS settings.

The AVR should be disconnected from Mains and Load before commencing this test. 17. Increase the variac until the AVR output is 241Vac +/- 0.5V. SLOWLY turn P1 anticlockwise until the output voltage drops (to approx. 222V). LED LD2 should now be on.

2. Increase input volts to 230V. 3. Two LEDs on selected phase of DSP should be illuminated. The DSP is situated at the rear of the AVR. It may be necessary to remove the back panel to access the DSP.
