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 Emergency Stop button on the operator box, 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.
d. Follow correct lockout/tagout procedures.
2. Unplug and firmly reseat connectors.
7.12 POWER DISTRIBUTION SUBSYSTEM
Electrical power is run through a single power cord to the Main Disconnect switch. This switch controls all power to the machine, the
coolant pump, and the PathPilot controller.
To troubleshoot the power distribution subsystem, read the following:
7.12.1 The Controller Won't Power On 60
7.12.2 The Coolant Pump Won't Run 61
7.12.1 The Controller Won't Power On
Cause: The PathPilot controller isn't plugged in to an outlet.
Probability How-To Steps Need More?
High
Reseat the power cord connection at both the outlet and the controller.
It's possible that the power cord could
become loose from movement.
Cause: The CB3 circuit breaker tripped.
Probability How-To Steps Need More?
Medium
If the monitor and the controller both don't have power, examine the
power cords for damage or exposed wires, and then reset the CB3 circuit
breaker.
CB3 affects the monitor and the
controller.
Cause: The video cable is disconnected from the PathPilot controller.
Probability How-To Steps Need More?
Low
Reseat the video cable connection at both the monitor and the PathPilot
controller.
If the monitor is disconnected, it could
seem like a controller power issue.
