The control RS200L possesses an integrated protection circuit against uncontrolled movements. It is
activated if during normal operation an emergency stop signal is given to the dock leveller or if voltage
supply is interrupted. After release of the emergency stop or power up, the dock leveller the valve stay
closed, until the push button leveller up button is activated.
8. Overload protection
The control RS200L possesses an integrated overload circuit for the hydraulic unit. Each phase is
examined for overload. As soon as this is the case, the contactor switches automatically off. Further the
circuit is secured against phase failure. Both errors are signalled by the red LED LE1.
