Next season we hope to have a limited release of 500 Cordless Teth-Air systems. I case you have not heard about it, it is a wireless tether system to give the rider a working radius of about 5 feet around your sled, if you get farther the sled shuts down. The rider wears a small tag transnitter and the receiver is mounted on the machine. US patent US 7,034,696 B2
Here is where I need your help: In our design we utilize a small relay that will close for 3 seconds when the signal is lost. We have been testing on Doo's and simply short across the kill switch wiring. I hear that Cat is wired opposite and we need to open this circuit to kill the motor? This is no problem as our relay is single throw, double pole. The problem is we are concerned that the current in the kill switch curcuit will exceed what our 2 amp relay can handle?
Can anyone tell me if there is a low current tie in that we can use to kill the motor?
We do realized that on th old Doo's (pre DPEM) we will have to offer a 30 amp relay/ 9 volt battery option (wiring kit) as these old types simply short the coil and the current will melt our smaller relay.
Any input is appreciated.
