8.1 Error codes and messages
• This product is designed to indicate an error status on
the front panel (See the following figure) as shown in the
following table when an error occurs and it can be self-
examined.
• In the case of welding errors that are not covered in the
following table, see “Troubleshooting” table.
DANGER
Touching the current-carrying parts may cause a fatal electric shock or
burn injury.
To prevent a physical accident, such as an electric shock, burn injury, etc., make sure
to observe the followings.
• Make sure to turn off the power and other switches of all devices * for safety reasons before taking
any actions for correcting an error.
* : Means this product, the distribution box and other related devices (jigs, robots, etc.)
• As for the inside inspection, make it at least 5 minutes after turning the power off in consideration of
electric discharge from a capacitor.
CAUTION
• When the power switch is turned off automatically, contact sales distributor or Pana -
sonic representatives without turning it on again.
• The power switch uses a non-fuse circuit breaker. If over-current occurs for some
reasons, the power is turned off automatically (tripping). Do not turn it on again.
• (It is dangerous to turn the power on again without removing the cause of such over-
current.)
Notice Do not turn the power on with the top panel and/or side panel of this product removed.
The electromagnetic force may cause troubles (deformation, mechanical contact, etc.) to the inside devices and parts,
and may break them and/or affect their functions and performance.

Those error code is also indi -
cated on the 7-segment LED on
the PC Board (ZUEP1398)
