Helios W2T

[Christian Larsson]

I got a Helios, a rather late,
marked Si-lectron on notes, anyone know anything?
everything seems to work except Wersi Vision I have not started.
There are micro switches S4 / 1 to S4 / 6 with drawbars settings,
is it possible to save your own drawbars settings there?
about how?

Hi,

The label "Si-lectron" is only a label from factory who made the wiring harness " PR 20 ".
This is only the wiring harness of the Soundcomputer component.

With the micro switches You can chose between the 6 possible drawbar programms.
To change any drawbar programm You must do this by change the resistor values on the
presets boards which are pluged on the drawbars. They were named PZ (number).
One of these programs ( programm 6 ) You can change by the trimmpots on the boards.
Each position between 0 - 8 of a drawbar refers to a certain resistor value.
This is documented in the Manual of the Soundcomputer.
So changing any Drawbar setting means to solder the recommended value of the resistors
to each drawbar of this programm.

The Wersivision is a component of the organ which only drives the piano. The wersivision itself
doesn´t produce any sound. So when the piano doesn´t work the wersivision also can´t work proper
So You have to activite a Soundbutton of the piano of upper manual piano.
The button Auto trigger and a direction up or down must be selected in switch field of the
wersivision.
Then You must play a key or a chord in lower manual . All pushed keys of the chord will then sound
from lowest key of the manual to the highest key if the button " Upstairs " is pushed an will sound
down from highest to lowest key when the button "downstairs " is pushed.
If the button either up/down is selected too the keys will run up and down when upstairs pushed
or down and up when downstairs is pushed.
If the button CIRCLE is pushed too to up or down button the sound will run in a circle permanently
and only stop when th button Auto Trigger is OFF.
The Speed can be vari with the APPERGIO TIMER Poti ( besides Slalom and VCF Slider )
But if the drumcomputer is started the wersivision will automaticly continue with the tempo of drums.

In beginning of the Helios generation 1976 Wersi itself produces all the wiring harness.
Because of rising demand they had to delegate the production of the wiring harness besides
parallel own production.
One of these companies was " Si lectron" as shown on label.
