18.9 Notes
18.9.1 Note 1
The fluorescent lamps’ circuit is based on 230v. Except with certain ’UL’ models, there are always
230v at the lamps’ socket on the amplifier panel independent to the factory set mains voltage! Lamp,
starter and ballast is a matched group, never use replacements of other wattage! Check for a
defective starter before you check for a defective lamp.
18.9.2 Note 2
Some actual low tension power readings (averages). Numbers left of/are effective (R.M.S.) values,
read with a moving iron instrument. Numbers right of/are mean integrated values, read with a
moving coil instrument.
18.9.3 Note 3 A
A selected record can be located properly only as long as the light gate is working properly. The
counting pulses can be checked easily by observing the LED indicator Z which has to light up
rhythmically when the carrier is rotating (unlock the carrier latch manually for a check).
LED Z is dark whenever the carrier stops but has to light up as soon as a tooth tip of the carriers’
base plate has passed the carrier latchs’ front edge for about 1 - 2mm. For a check lift the carrier off
its friction drive wheel a little, unlock the carrier latch with the other hand and advance the carrier
slowly manually.
