The duty cycles of the PWM signals are pre-configured for each NOX model, but
these may be adjusted as required.
Minimal duty cycle: The valve coils require a minimum electrical potential to open.
If the minimum is set too low, a long dead time will result. This means that the
function will only start once the joystick is seriously deflected.
Maximum duty cycle: Normally, valves have the highest oil flow at 90% duty
cycle, i.e. 90% is the ideal maximum duty cycle. If the maximum speed is reduced
and more linear movement results, the maximum duty cycle may be reduced.
WARNING
Risk of serious injuries through unexpected tilting or rotating of the tiltrotator!
•
Only allow correspondingly trained personnel to adjust the duty cycle.
1. Tap the
Tilt
,
Rotate
,
Extra 1
,
Extra 2
and
NOO
buttons.
2. In each case, adapt the minimum and maximum duty cycle.
3. Tap the
Select model
button and select the NOX model anew to reset the
settings to the standard values.

Carrying out automatic calibration
If the tiltrotator has a rotation sensor, automatic calibration can be carried out.
The valve values for the tilting, rotating and for the pressure reduction valve are
automatically set during automatic calibration.
1. If the pressure reduction valve used is not standard, ensure that the type of
pressure reduction valve is set, see "Setting the pressure reduction valve".
