4. CABLE FOR OPTO FIBRE OPERATION ( NOTE ! OPTION ).
For opto fibre control the remote control system is complemented with an opto fibre cable,
battery pack and battery charger. This means that light is used to send the control information
( not electrical impulses ).
The control unit is connected to the electronicbox via a thin opto fibre cable. The cable has
circular type contacts (Ampehenol / Hirchmann) at each end and the opto fibre electronics is
built in and integrated into the contacts.
Opto fibre cable is used in those cases where the use of traditional control cable is not allowed. This can be
during work under or near to electrical power lines or ground cables where contact or flash-over between
control unit and crane could be fatal.
With opto fibre cable the control unit and electronicbox ( crane / vehicle ) are not electrically connected, i.e. are
totally isolated and galvanically separated.
( Radio control gives the same personnel protection ).
