System Test, Manual
This test is for your benefit, to verify that nothing broke in shipping.
Perform this test after attaching loader to GT, and before doing any critical alignment of the
hopper and loader. The only alignment requirement is that the pushrod moves freely in the
spindle liner bushing. Do not put any parts in the hopper yet.
Set disconnect on spindle cabinet ON; set CNC control ON. After boot-up, set servos ON.

2. Verify that green stacklamp is lit.
3. Push loader shuttle against adjustable home stop; verify that “Home” LED is lit.
4. Move the shuttle to “InPlace” sensor; the LED on sensor should light.
5. Move the shuttle to the “ Slow” sensor; the LED on sensor should light.
6. Move the shuttle to “ EoB” sensor ( End of Bar); the LED on sensor should light.
7. Push the shuttle right, until “ Eject” sensor LED lights.
