How to Adjust the Dead Bands
A deadband is an area of regulaon range where no acon occurs. The purpose
is to prevent involuntary power feeding to the coils. If no deadband is dened,
the electronics is feeding random signals to various coils, and if the deadband is
set too narrow, even a small unintenonal movement of the lever can cause a
harmful addional reacon.
As an example: A small side movement of the joysck can cause the rotator to turn
when the aempt was to rise or lover the main boom of a forest crane.
Seng the deadbands will always recall, by the program selected current values.
Because the current values starts from low, at all lever direcons of the joysck ( even
the thumb roll ) shall all hydraulic movements start smooth from a low level, without
any preset speed. The current starng from low level will lead to a relavely long lever
movement for gaining a required current for start in some funcons. To adjust these
funcon to start smooth, immediately aer the deadband, please read the manual at
page 29.
The procedure to set the deadbands / returning the factory
sengs:
(the hydraulic pressure can be on because the joysck will not give any out
signal) Note: At the referred switches A and B, A is marked with a cavity.
 Switch off the power from the joystick
 Press and hold A and B switches.
 Turn on the power to the joystick, still holding A and B pressed until
the red light come on after 5 seconds. Then let off the switches.
 To set the deadbands at the joystick move the lever apr. 10 mm in
every direction, also the roller apr. 2 mm forward and back.
 Press A switch to register the deadband values (just press, don’t hold)
 The red light will flash to indicate the registered values.
 Move the lever to the maximum position in all directions, also the
roller.
 Press A switch to register the maximum lever values.
 The red light will now be on for 1 second to indicate the finished
procedure.
 The joystick is now ready for use.
Note: The length of the deadbands can be set longer than 10 mm if wanted
but not shorter to avoid earlier menoned unintenonal movements.
