KRS Footswitch Description
The Hall Effect Transducer has an operational life of up to 50 million actuations as compared to a normal resistance potentiometers currently used, which only have an operational life of less than 1 million actuations.
The Foot Switch features intelligent software to monitor the limit switches and Hall Effect Sensor and then in turn, outputs the correct signals to the Drive system and the shuttle car electrics. If an error is detected the software will disable the outputs which in turn will stop the vehicle.
The Electronic hardware also has a micro monitor watch dog system which checks the health of the microchip and the program running inside it. There is also a power up check that is carried out, that will disable all the outputs if the software finds an error in the footswitch or if it is not in the neutral position. The software will disable all the outputs (Forward, Reverse, Neutral and the Analogue Control Output) from the footswitch.
Also featured within the Footswitch is an Optional serial port which allows the end user to interface directly with the vehicle’s controller PLC if available. This then allows the user more information for a higher level of diagnostic capability than before.
The Footswitch unit is packaged complete with the mechanical arrangement so that it can be installed directly into most existing enclosures found on typical underground mining machines and is also easily integrated into above ground machinery requiring this type of control.
The internal centering spring automatically returns the footswitch to the neutral position when the operation force is removed. The centering spring works in conjunction with external centering springs and linkages found on most shuttle cars.
