Background
Our main indicator of the source of the fault is the machine LED light on the 15L’s electrical cabinet. It’s status indicates which subsystem to begin checking for the estop fault.
Dark - the estop circuit has been interrupted
Solid - communication with Pathpilot has dropped
Blinking 50/50 on/off - VFD has faulted
Blinking 10/90 on/off - turret tool change has failed

are not tripped. The 15L is equipped with two estop buttons:
On the front of the electrical cabinet
On the tray of the controller arm
Verify that fuses FU1, FU2, FU3, FU5, and FU7 are not blown and have a reading of between 0.1 and 1 ohm. Below or above 0.1 to 1 ohm indicate a fuse that needs to be replaced.
Verify that the 24v DC power supply is outputting at least 24v and less than 28v.
Verify that the main control board is receiving 24v DC power by measuring between terminals J5-1 and J5-2.
Communication with the controller has been interrupted
Verify that the DB25 cable is fully inserted to the machine and the controller.
Verify conductivity on the pins of each of the conductors in the DB25 cable and J4 cable.
If using a tower controller, check the Mesa card for solid red lights, indicating a hardware fault on the Mesa card.
VFD fault
Check the display of the VFD for the fault code.
Turret tool change has failed
...
Check for physical obstructions to tool change (like a part or chuck)
Turret lock switch adjustment (if turret reverses)
...
Verify that there are no physical obstructions that the turret could have hit
Verify that the turret is filled with oil
Oil for Gen 1 turret
Oil for Gen 2 turret
...
Turret control board/main control replacement (if turret does not reverse)
If the turret does not turn at all: verify that the turret control board is receiving power on J14-4 and J14-5.
Verify that the F1 and F2 fuses on the turret control board have a reading between 0.1 and 1 ohm. Below or above 0.1 to 1 ohm indicate a fuse that needs to be replaced.
Gen 2 - Verify that the motor will turn by taking the belt off and command a tool change
If the turret will turn forward but will not turn in reverse, the lock switch may need to be adjusted
