<p>The present invention relates to a system (100) for controlling a quick coupler (101); which quick coupler is arranged at an tool arm and is arranged to assume a locked position in which at least one tool/accessory is locked to the tool arm and an unlocked position in which the tool/accessory is detached from the tool arm, which system comprises a first control unit (111) arranged to receive an input signal S1 and, after a first checking procedure (CM1), to output a first control signal S1 to at least one control means (121, 122), the system further comprises a second separate control unit (112) arranged to receive the input signal S1 and, after a second separate checking procedure (CM2), to output a second control signal S2 to the control means (121, 122), wherein the control means (121, 122) is arranged to control the quick coupler (101) to the unlocked position if the first control signal S1 and the second control signal S2 both indicate a value (V1, V2) which correspond to a valid signal for the unlocked position. Furthermore, the invention relates to a machine comprising such a system.</p> |
