Basic Function Check
Check that all systems involved are working properly, starting with the proximity switches.
In keypad mode (K) move the X-axis into the proximity target
using the left arrow on the keypad. The proximity switch will
have a red LED lit until it comes across the proximity target,
when it will turn off. Moving off the top of the target should
cause the LED to come back on. This should also be evident in
the ShopBot position screen when looking at input “2”, the light
will turn from black (normally closed) to green (open).
In keypad mode (K), move the Y-axis into the proximity target
using the down arrow on the keypad. The proximity switch
will have a red LED lit until it comes across the proximity
target, when it will turn off. Moving off of the target should
cause the LED to come back on. This should also be evident
in the ShopBot position screen when looking at input “3”.
In keypad mode (K), move the Z-axis into the proximity target using “Page Up” on the keypad. The
proximity switch will have a red LED lit until it comes across the proximity target, when it will turn off.
Moving off the top of the target should cause the LED to come back on. This should also be evident in the
ShopBot position screen when looking at input “5”. Input “5” will appear green until the target is hit then the
input goes black.
