2 – Vertical Load Configuration
2 – 1.Operating Principle
.
In order to of fset the downward movement of the arm before it is raised,
a vertical load compensation must be implemented.
. This compensation adds a current offset which may be positive or
negative depending on mechanical configuration.
. The required option is selected using a strap.
. The offset value is defined by resistor R120 = 80K
