KUZMA LTD INSTRUCTION MANUAL FOR STABI XL 4 kit turntable The Stabi XL 4 KIT: converts Stabi XL2 turntable into Stabi XL 4 version. The difference is the addition of two extra motor towers to make 4 motor towers in total with 4 belts. These give more stable drive to the platter and there is a new better power supply. All this add 20kg to the total weight of the turntable. General Description: The kit is packed in two boxes. Some parts are very heavy so handle the box with care .
Unpacking: The boxes and some parts are very heavy, so handle very carefully and place parts on assembley surface. Contents: Motor towers 2x, belts 2x, motor towers support platform 2x, connecting cables 2x, PS XL II, motor positioner, instruction manual. Basic setup Motor towers: Remove the two brass motor towers with the black pulleys, being careful not to touch the pulleys with any force.
Power supply (PS XL 2=4=MCU): General description of PS: The AC motor power supply generates dual sine wave ouput to control rotation and speed of the AC sycnhronous motors. The signal is generated by quartz and controlled by a sophisticated computer based program. This allows for very smooth generation of the sine wave with very fine choice of speed. Each speed can be selected, finely adjusted independently and then stored in the memory. PS is factory preset.
Fine speed adjustment: Observe on a strobe disc if the bars are stationary. If not ( bars move in the same direction as platter rotation then the speed is too high) then press few times( there are very small steps- so keep pressing) the plus or minus buttons until the bars are stationary. On the display you will see a green dot in the right bottom corner indicating that change is in process. Using a sharp pen, press the store button and the green dot will disappear.
Fig.3 Problems: A.Speed:To reach correct speed, adjusted it on the PS. Also check that the distance of motors to the platter are correct. B.If the speed is totally incorrect: Reset to factory preset. Finally repeat factory preset and fine speed adjustment. Kuzma Ltd Hotemaze 17A SI-4205 PREDDVOR SLOVENIJA Phone: + 386 4 25 35 450 Fax: + 386 4 25 35 454 E mail: kuzma@s5.net www.kuzma.
