16.3 Resetting the Exhaust Fan Overload Relay
Machines with exhaust fans may have errors if the overload relays trip. Do these steps
to return to normal operation:
1. Set main power switch to “OFF”.
2. Open the electrical enclosure.
3. Examine the overload relay for a tripped flag.
4. Make sure that the current set point is set correctly on the overload relay.
Examine the rating on the exhaust fan housing for current draw.
5. If necessary, push the reset button to reset the relay.
6. Restart the machine. If the problem persists, refer to for more information.
16.4 Pneumatic Error Recovery Procedure
The system’s pneumatics are checked for errors every time they operate. The
pneumatics must be in their home position before the axes can home or move to the
standby position. If a pneumatic fails, an error will be shown.

1. Find the cause of the problem.
2. Correct the problem.
3. Select “Continue”.
4. Refer to the pneumatic actuator failure section in your workcell manual for

1. Find your error type.
2. Find the program line number.
3. Record info (error and line shown in the system messages window) and contact
PVA Technical support.
4. Select continue.
5. Do the startup/recovery procedure. Refer to Section 16.1.
6. Download the updated program and run it to see if the error was corrected.
NOTE: For more on error codes please refer to the Troubleshooting guide. For
more information on programming paths, refer to your PathMaster manual.

16.6 Position Error Recovery Procedure
A position error occurs when the difference between the commanded position and the
current position is more than the maximum allowable error limit for an axis.
You can get an error limit if the dispense/spray head hits a hard stop in Manual mode, if
the speed or acceleration is set too high, or if the axes drives are not powered. Make
sure the “Emergency Stop” button is not engaged. The motor stop codes are shown in
the system messages window.
NOTE: Refer to Section 16.8 for more information on stop codes.
Figure 99: Position Error
To correct the position error, do the steps that follow:
1. Engage the “Emergency Stop” button.
2. Open the access door.
3. Move the dispense head to the center of the work area. The Z-axis has a brake.
Turn the Z-axis motor coupling by hand to move the dispense head as
necessary.
4. Close the access door.
5. Disengage the “Emergency Stop” button.
6. Select “Continue” to clear the error.
7. Do the startup procedure.
