We have a simple machine we are building, but it is different from other machines we have built in the past. Normally we do fully automated cells, with little or no operator interaction. We have a simple Camco indexer that will spin a table within the operators work envelope. Is it enough in the US for the safety to just disable the "Enable" control circuit or does it have to cut power to the motor directly when the 2 hand safety relay isn't made?
The manual for the indexer states that the enable circuit must be disabled BEFORE motor power is cut. How does one achieve this? Timers? Seems silly for a 2 hand safety circuit to have timers.
I know a lot of these questions here get jumped on in a rude way because it's hard to be specific about safety when you don't see the whole picture. I'm not going to stand in court and say 'some guy from Control.com told me this was okay'. What I'm looking for is where one would even find this information at?
I appreciate any help from someone more senior than I, as I am just starting out in this path.
