3.7.2 Earth
The earth connector of Ventura Vico is connected to the protective earth
conductor of the cabinet or system / machine element. Use the flat plug (6.3
mm x 0.8 mm) at the back of the unit.
Verify that the cross section is not less than 2.5 mm
2
. Use fine-wire cords -
they are the best to dissipate fault currents. Try to keep the lead to the
earthing terminal as short as possible.
A low-impedance earth conductor improves the dissipation of interference
received via external power supply cables, signal cables or cables of periph-
eral units.

External and internal potentiometers work in parallel. To make use of the en-
tire adjustment range, set the internal potentiometer to maximum brightness.
Verify that the external potentiometer's resistance is 4.7 k
Ω.
3.8.1 "DVI" Graphics Interface, "X3"
The DVI-D port transfers the digital screen data and can thus be used for
monitors with a digital DVI port.
If attached to the Ventura controller PC, special leads support lengths of up
to 20 m. Use an optional DVI extender to bridge larger gaps.
To ensure that the control and display monitor is correctly detected and ac-
tuated by the BIOS and operating system, it should be attached to the PC
when the PC is switched on.
