PS REF 2:
Front panel
General description:
The AC motor controller unit generates a dual sine wave output to control rotation and speed
of two AC synchronous motors. The signal is generated by a sophisticated computer based
program. This allows for 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. The
PS is factory preset. Connect the motor cable to the motor output.
It may take few hours for a new turntable to settle at the correct speed. When the PS is
unplugged, the preset speeds will be stored.
PS (Motor controller unit-MCU) connection:
Position the MCU in such a way, that it will be convenient for operation of the turntable. You
should, however, allow space above for ventilation, of at least 10-20 mm.
The cable which connects the motor controller unit and turntable has a five pin DIN plug,
which should be inserted and locked into the connectors at the rear of the MCU and turntable.
Connect the mains cable into the mains and then switch on the MCU at the rear panel, which
is left permanently on. A red light and green display will light up on the front panel.
Operation:
1. Press the power button at the rear of the MCU firmly. After 10 sec the MCU is ready. The
display will show 33 and above the start button a red LED will be shown. You can keep the
MCU switched on all the time.
2. By pressing the start button the red LED will turn green and the platter should start rotating.
To stop platter simply press the start button again. The red LED will show and the platter will
stop rotating.
3. Press the speed button and the selected speed will change from 33 to 45. Press again and it
will return to 33.
4. Do not press the start button before the mains switch is on.
