REMOTE CONTROL FOR BATTERY-OPERATED HYDRAULIC POWER SYSTEM
First Claim
1. A remote control unit for controlling a battery-operated hydraulic power system, the remote control unit comprising:
- a hydraulic actuator command circuit configured for generating a command signal for commanding operation of an hydraulic actuator of the battery-operated hydraulic power system;
a battery level control circuit configured for receiving a control signal representing a battery level of a battery, or of a group of batteries, of the battery-operated hydraulic power system; and
an operator assistance module, operably connected to said battery level control circuit, said operator assistance module configured for generating at least one operator assistance event, said operator assistance event being associated to said battery level.

Abstract
A handheld wired remote control unit for battery-operated hydraulic power systems comprises a hydraulic actuator command circuit, a battery level control circuit and an audio/visual operator assistance module. The remote control unit generates a command signal in response to action on the remote control unit by an operator so that the hydraulic actuator can be operated. The battery level control circuit receives a control signal representative of a charge level of a battery that supplies energy to said actuator, and processes it. The audio/visual operator assistance module thus generates an operator assistance event related to the charge level of the battery, such as a flashing light or a buzzing sound. A battery cut-out circuit in the operator assistance module prevents operation of the actuator when the battery level is too low.
