SmartPAC 2 Fault Messages
The information, or "checksum," created for the tool number loaded has
become corrupted. This can occur when SmartPAC 2 has been turned off
while you are in the middle of programming a setup, or when you have not
properly exited (by pressing RESET) from a Programming or Run menu.
This can also occur when you upgrade SmartPAC 2. Sometimes the
information in the older firmware does not correspond properly with the
new firmware.
SmartPAC 2 creates a checksum for a tool number to check that the
data stored in memory for the tool is the same as the data that comes out of
memory when you load the tool number. The checksum value calculated
when data went into memory must be the same as the value calculated
when the data is loaded.
These checksum values may not match if SmartPAC 2 has been turned off
while you were in the middle of programming or adjusting settings for a
tool. It will also happen if the stored tool number settings got damaged due
to an internal SmartPAC 2 malfunction.
Go back into programming and review the tool number setup in question.
Make sure that all the information you programmed is correct; then reload
this tool number. If the problem was caused because the system was
turned off while in Program or Run modes, perform these steps:
Press the RESET key to clear the fault message.
Go to Program mode, and select "Program/load tool numbers."
Select the tool number in question from the tool number display.
Select "Modify the tool information" from the next display.
Select "Counters" from the next display.
Press RESET. SmartPAC 2 will create a new checksum for the tool
number.
Select the tool number again, bring up the display of cams, and verify that
all settings are correct.
Reload the tool number. You should not get this fault message.
If the problem is due to a system malfunction, the tool number settings
will have to be created again from scratch. If this happens more than once,
contact Wintriss Tech Support for assistance.
