Troubleshooting
If Something Goes Wrong . . .
Some problems encountered when using the workcell are easy to identify and solve. Others require more
extensive help. This troubleshooting section is designed to assist an operator in solving problems before
seeking additional help. It is strongly recommended the operator check this section first if a mechanical or
electrical problem occurs. Remember, not every problem can be described in this section, but this should
be a good place to start.
NOTE: If a problem occurs while running a particular path program, consult the separate
PathMaster® Manual for information on debugging code problems.
Calling Technical Support
The technical support staff is always available to help solve any problems. The phone number is (518) 371-
2684. To assist in the troubleshooting process, it is best if as many of the following items are addressed
before calling for help:
1) Record all the information on the OIT when the error occurred.
2) Take note of the operation in progress when the machine developed trouble (when did it have
problems, what was it doing, etc.).
3) If the error was not serious, attempt to repeat the error. If the error does not repeat, the problem may
have been operator generated.
4) Use a terminal screen to communicate with the controller. Most troubleshooting necessitates issuing
commands directly to the controller.
5) If the problem is programming related, a hard copy or email of the program in question may be
requested by PVA. Please be prepared to send it. The PVA fax number is (518) 371-2688, or the
customer service representative will provide an email address, if all parties are email capable.
Fault Diagnostic
The PVA550™, PVA1000™, PVA2000™, and PVA3000™ models use a closed loop servo drive system
were as the PVA250™, PVA750™ and PVA2000C™ models use an open loop stepper drive system.
Listed below are are general fault diagnostic table for each type of system.
