there are two different mechanisms to determine if the slide is in enough to push the pins down. one is a microswitch somewhere. the other is like i have. a dime sized magnet glued to the top of the slide near the hole for the slide pins. when the hall effect sensor detects the magnet, it says that slide is in far enough. when the magnet comes unglued and comes off, it will not put the pins down. if you get a loose magnet near the sensor when playing with the slide, the hydraulic pins will go down and easily punch nice round holes in the top of the slide. dont ask how i know.

i was having some problems with my bedroom slide pins engaging and i moved the magnets and it worked fine.
