The control unit is comprised of manouevre levers for proportional control, switches for
ON/OFF and function changing, micro-operation and emergency stop. ( See separate headings
below ).

The manoeuvre levers give fully variable proportional operation and are sprung loaded to
return to zero position, i.e. "dead-man’s-handle". When the manoeuvre levers are moved from
zero position the respective hydraulic function starts to operate slowly and increases in speed
as the lever is moved further from zero position and vice versa as the lever is moved back
towards zero position. If any levers are not included for a particular installation, a cover plate
can be mounted for the unused lever locations.
