Problems
Platter not rotating:
Motor controller unit- check if the red LED is on
-green displays shows 33 or 45, if not re-plug MCU
- check connection cables from MCU to motor
Consult dealer or qualified electrician.
Very slow start:
Only one motor receives output from PS: MCU. Remove the platter and belt and check that
the motor pulleys are rotating. If only one motor pulley rotates, disconnect the mains and
connecting cables and check if there is a failure of the MCU. If both pulleys are rotating, try
to slow them down by braking with fingers and observe how much force is needed to slow
them down. If this is not much and if you can manage to rotate it in the opposite direction,
re-check MCU.
Wrong speed:
If you find out that your speed selection is out of range for some reason you should reset PS to
factory set outputs:
First check position of the belt and height subchassis.
Factory preset:
Turn the power off, wait 10 sec and then press and hold speed button, then press power on.
When display will shows CU, release the speed button. The display will now show FA and
then 33. Your PS is now preset for factory preset speeds.
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.
Suspension:
If you can not properly adjust the height of the top subchassis or if one corner is not moving, it
is possible that one or more of the adjustment knobs is out of adjustment range. The solution
is simple.
Remove the platter and belts and lift up the subchassis. Under each corner knob are silver
finished spikes, which fit into the top of the suspension reservoirs on the corners of the base
chassis. With another person holding the subchassis, or by positioning it on a soft surface,
check the height of the silver spikes. Holding a knob in one hand, rotate the spike along the
screw until the spike point is approximately level with the lower edge of the subchassis.
Adjust all four knobs and return subchassis, belt and platter and readjust the height.
