Proximity switches

[khaos]

All my proximity switches are lit up except when the pass near the sensors. Is this right? When trying to set up the zero using proxi switches it wont go/run as it says one of the proxi switches is triggered ... I have even moved the router and x car to the center of the table ...

Joe,
The Proximity switches for the PRS machines are normally ON all the time, except when they sense the target, then they turn off. Be sure that you've configured the switches correctly with the VN command (Normally Closed)

ok, This is resolved. My issue was that I had set the proxi switches exactly on the zero mark.

My proximity switches stay on until they come in contact with the targets and then they go out...the problem I have is that when I test them according to the manual, they go beyond the targets...help
thanks,

Dick,

Check to make sure that "Limits" are "On". Hit VN and set them to "On" if they aren't.

they are on Scott...any other ideas??

Make sure you have them wired per the manual. Validate that the "green light" image in the shopbot software turns red when the actual light goes out on the switch.

From the manual:

"• Use the KeyPad to back off the Proximity Switch. The LED should come back on. You
can test the “Limit” Function of the Proximity Switches with the KeyPad. First use the
[VN] Command to turn the Limit Switch functionality on. Now use the KeyPad to
drive into the switch. Your tool should stop. After hitting a switch, the KeyPad then
overrides switches if you use it again, so you can drive off the switch. After you have
driven off and released the arrow key. The switches will again function as limits."

You must let off the button after moving off the prox switch to reset the switch to work again.

Group-

I just received (Friday) my BT48, and all is going well. It's been uncrated, set in position, leveled, and now I'm going through "air motions".

One question about proximity/limit switches. Can you drive to "any" location without damage? I mean, do the proximity switches provide constant protection, or are they only a way to give a hint you're about to overrun travel in a given direction?

David...
Assuming setup as per instructions, the prox switches will work to bring the machine to a dead stop upon activation. This will work during both slow and fast moves. (dont ask how I know this) Make sure that there is the recommended distance from the prox's to the hard stops.
