<p>PURPOSE:To operate plural machines to be controlled at the state of the best efficiency automatically without depending on the decision of an operator by indicating the operation time of the running machine to be controlled on an operation time indicator, and performing various kinds of operations based on this indication on the same operation indication panel by the operator. CONSTITUTION:For instance, when an operation time display switch 4-1 is operated, and a contact 4-1a is closed, a signal corresponding to the contact input is inputted to a controller 10, and on the one hand, the switch surface of the operation time indicating switch 4-1 is lighted steadily, and on the other hand, the operation time of a pump is indicated on an operation indicator 1. When the contact input is inputted from each contact of a input side, an operation display generates the signal corresponding to the contact input by the controller 10, and outputs and indicates this signal on each indicator or the like of an output side. Then, since the respective indicators 1, 2, 5, 6 are installed on the same operation indicating panel surface, the operation can be performed easily. Thus, plural machines to be controlled can be operated at the state of the best efficiency automatically without depending on the judgement of the operator.</p> |
