Diagnosis

Using the master‐slave connection (X6, X7), a slave informs its master
only globally about an error state, not about the precise error cause. In
this case, the master disables its "ready" state (as the slave before­
hand).
In order to eliminate slave errors that cannot be reset by a simple "error
reset" at the master (see note below), the precise error cause must be
known and, if necessary, the error must be manually acknowledged di­
rectly at the slave (in case of non-self-acknowledging errors; see note
below).
For that reason,
• you can connect (X1) a laptop with installed user interface ("BOS" or
"LT IB" with the type PSI 6500.000), for instance, to the slave, read
the slave error via the user interface, eliminate and, if necessary,
acknowledge the error,
or
• you can connect all slaves to a higher-order welding processor (PC
with BOS user interface) via a programming bus interface, in addition
to the master. This centrally provides the possibility of displaying and
resetting the error for all units that are connected.
"An "error reset" at the master can be achieved via the user interface
or via the Reset button on the front panel.
