Assignment of DIL switch settings on the card to the valve
types (see also label on the printed-circuit board)
Meaning of potentiometers "Zw" (R130) and "Gw":
– Adjustment of biasing current by means of potentiometer
"Zw" (R130)
• Turning clockwise → increase in biasing current
• Turning counter-clockwise → reduction of biasing current
– Adjustment of the max. command value by means of potenti-
ometer "Gw"
• Turning clockwise → increase in command value
• Turning counter-clockwise → reduction of command value

Note (X):
With type VT-VSPA1-1 (component series 10) switch BR22
must be set to “ON” and potentiometer “R130” turned to “left-
hand limit stop” before the correct characteristic curve can be
set.
With type VT-VSPA1-1 (from component series 11) and type
VT-VSPA1K-1, switch
S22 is ineffective. Po ten tio me ter "Zw"
needs not to be operated.
