Abstract

A safety switch allows for greater safety and greater ease in operating a machine where multiple operators may be required. The safety switch allows multiple operators in different locations to exercise control over the machine, reducing the risk of accidents and improper operation of the machine.

Claims (38)

1. A method for controlling a machine, the method comprising:

receiving a connection of the machine at a master control module, the master control module configured for selectively providing power to the machine;

receiving a connection of a main switch and a secondary switch at the master control module, wherein the main switch and the secondary switch are in different locations;

selectively providing power to the machine when both the main switch and the secondary switch are actuated; and

selecting whether actuation of both the main switch and the secondary switch provide power to the machine or whether actuation of only the main switch provides power to the machine.

2. The method of claim 1 , further comprising displaying operational parameters of the machine at the master control module.

3. The method of claim 2 , wherein the machine comprises a wire puller and wherein the operational parameters comprise a force applied to a wire by the wire puller.

4. The method of claim 1 , further comprising providing an indicator at the master control module to show at least one of whether the machine is operating, whether the main switch and the secondary switch are actuated, or whether actuation of the main switch only provides power to the machine.

5. The method of claim 1 , further comprising providing an indicator at the secondary switch to show whether the main switch is actuated.

6. The method of claim 1 , wherein the master switch and the second switch are momentary contact switches.

7. A method for controlling a first machine, the method comprising:

receiving a connection of the first machine at a master control module, the master control module configured for selectively providing power to the first machine;

receiving a connection of a main switch at the master control module;

receiving a connection of a secondary switch at a slave control module in communication with the master control module, wherein the master control module and the slave control module are in different locations;

selectively providing power to the first machine when both the main switch and the secondary switch are actuated; and

selecting whether actuation of both the main switch and the secondary switch provide power to the first machine or whether actuation of only the main switch provides power to the first machine.

8. The method of claim 7 , further comprising:

receiving a connection of a second machine at the slave control module; and

selectively providing power to the second machine when both the main switch and the secondary switch are actuated.

9. The method of claim 8 , further comprising:

providing a sensor at the slave control module; and

when the sensor detects an occurrence of an event, ceasing power to the first machine and the second machine.

10. The method of claim 9 , wherein the first machine is a wire puller, the second machine is a wire feeder, and the occurrence of the event is a wire exiting a conduit.

11. The method of claim 8 , further comprising displaying operational parameters of the second machine at the slave control module.

12. The method of claim 8 , further comprising:

providing a sensor at the slave control module; and

when the sensor detects an occurrence of an event, providing an indication at the master control module.

13. The method of claim 7 , further comprising:

receiving a connection of a second machine at the slave control module;

providing power to the second machine when only the secondary switch is actuated; and

providing power to the first machine and the second machine when both the main switch and the secondary switch are actuated.

14. The method of claim 7 , wherein the master control module and the slave control module communicate wirelessly.

15. The method of claim 7 , further comprising providing an indicator at the master control module to show at least one of whether the first machine is operating, whether the main switch and the secondary switch are actuated, or whether actuation of the main switch only provides power to the machine.

16. The method of claim 7 , further comprising providing an indicator at the slave control module to show whether the main switch is actuated.

17. The method of claim 7 , further comprising ceasing power to the first machine when the master control module is unable to communicate with the slave control module.

18. The method of claim 7 , further comprising displaying operational parameters of the first machine at the master control module.

19. The method of claim 18 , wherein the first machine comprises a wire puller and wherein the operational parameters comprise a force applied to a wire by the wire puller.

20. The method of claim 7 , wherein the master switch and the second switch are momentary contact switches.
