Abstract
Abstract A method of, and apparatus for, controlling the startup, the normal operation and the stopping of all spinning positions of an open-end spinning machine provided with an electronic control unit supplied with power via a supply line. Control circuits extend from the electronic control unit to devices which influence the course of the spinning position. In the event of failure of the electronic control unit the normal operation is maintained.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
In a method of controlling the start-up, the normal spinning operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit supplied with power from a power source via a power line, and control circuits extending from the electronic control unit to devices which influence the operation of the spinning positions, the improvement comprising maintaining the normal spinning operation of the spinning positions of the open-end spinning machine in case of failure of the electronic control unit by continuing to supply power for the normal spinning operation from said power source to at least some of said control circuits.
Claim 2
Dependent Claim
106 words
In a method of controlling the start-up, the normal spinning operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit supplied with power from a power source via a power line, and control circuits extending from the electronic control unit to devices which influence the operation of the spinning positions, the improvement comprising maintaining the normal spinning operation of the spinning positions of the open-end spinning machine in case of failure of the electronic control unit by continuing to supply power for the normal spinning operation from said power source to at least some of said control circuits.
Claim 3
Dependent Claim
44 words
The method as defined in claim 1, further including the step of providing a shunt connection between the supply line and at least some of the control circuits extending between the electronic control unit and the devices influencing the operation of the spinning positions.
Claim 4
Dependent Claim
28 words
The method as defined in claim 1, wherein the normal spinning operation of the spinning positions is maintained during repair of the failure of the electronic control unit.
Claim 5
Independent Claim
121 words
An apparatus for controlling the start-up, the normal operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit, a power supply line for delivering power to the electronic control unit, control circuits extending between the electronic control unit and the spinning positions for influencing the operation of such spinning positions, a relay provided with a self-holding contact, a switch connecting the relay with the electronic control unit, first contact means and second contact means, said relay being operatively connected with the first contact means for opening at least some of said control circuits and with said second contact means for connecting at least some of said control circuits with the power supply line.
Claim 6
Independent Claim
121 words
An apparatus for controlling the start-up, the normal operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit, a power supply line for delivering power to the electronic control unit, control circuits extending between the electronic control unit and the spinning positions for influencing the operation of such spinning positions, a relay provided with a self-holding contact, a switch connecting the relay with the electronic control unit, first contact means and second contact means, said relay being operatively connected with the first contact means for opening at least some of said control circuits and with said second contact means for connecting at least some of said control circuits with the power supply line.
Claim 7
Dependent Claim
20 words
The apparatus as defined in claim 4, further including a manually-operated switch for connecting the relay with the supply line.
Claim 8
Dependent Claim
18 words
The apparatus as defined in claim 4, wherein said electronic control unit comprises insertable and exchangeable electronic modules.
Claim 9
Dependent Claim
32 words
The apparatus as defined in claim 6, wherein the electronic modules include operating and display elements for the simulating testing of such electronic modules without being connected with the electronic control unit.
Claim 10
Independent Claim
124 words
An apparatus for controlling the start-up, the normal operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit, a power supply line for delivering power to the electronic control unit, control circuits extending between the electronic control unit and the spinning positions for influencing the operation of such spinning positions, a relay provided with a self-holding contact, at least one first contact connected with an associated one of said control circuits, at least one second contact connected with another one of said associated control circuits, said relay being operatively connected with the first contact for opening its associated control circuit and with said second contact for connecting its associated control circuit with the power supply line.
Claim 11
Independent Claim
124 words
An apparatus for controlling the start-up, the normal operation and the stopping of all spinning positions of an open-end spinning machine comprising an electronic control unit, a power supply line for delivering power to the electronic control unit, control circuits extending between the electronic control unit and the spinning positions for influencing the operation of such spinning positions, a relay provided with a self-holding contact, at least one first contact connected with an associated one of said control circuits, at least one second contact connected with another one of said associated control circuits, said relay being operatively connected with the first contact for opening its associated control circuit and with said second contact for connecting its associated control circuit with the power supply line.
