12.4 FREQUENTLY FOUND PROBLEMS
There are several frequently found problems with all electromechanical machinery. Among the problems that have occurred, we've found
that the following are more frequent than others:
l
Loose Wires
Note: Before you begin the two-finger pull test, we recommend taking photos of the inside of the electrical cabinet to serve
as a visual reference while reconnecting any loose wires.
To determine if a wire is loose, use the two-finger pull test:
1. Power off the machine and the PathPilot controller.
a. Push in the machine's red Emergency Stop button, which removes power to motion control.
b. From the PathPilot interface, select Exit.
c. Turn the Main Disconnect switch to OFF on the side of the electrical cabinet.
2. With your thumb and index finger, hold the wire close to its termination point, and gently tug each wire.
3. If the wire comes loose, re-terminate and reconnect it before moving on to other wires.
l
Poor Cable Connections
An improperly seated cable may allow some functions to work but cause others not to. We have found that the ribbon cables’ plug
connections can become loose during the shipping process.
1. Power off the machine and the PathPilot controller.
a. Push in the machine's red Emergency Stop button, which removes power to motion control.
b. From the PathPilot interface, select Exit.
c. Turn the Main Disconnect switch to OFF on the side of the electrical cabinet.
2. Unplug and firmly reseat connectors.
l
Limit Switches
The X- and Y-axes have one limit switch located mid-travel, which actuates at the end of travel in each direction. The Z-axis has one
limit switch located at the upper limit of motion.
To learn more about the limit switches, see "Axes Drive Subsystem" (page237).
