<Current Check>

NOTE
If you cannot use the automatic current scaling function described above, the former scal-
ing function in the BOS is still available.
<Current Check> verifies whether the measured value of the primary current I
matches the secondary current I
It runs cyclically in the monitoring unit during the production process and serves to moni-
tor the measured values of the primary current I
gun circuit.
In the event of any mismatch between the primary and the secondary currents that go
beyond a specified tolerance band (BOS scaling mask), an error message is generated.
This error must be reset just like any other error.
A few new parameters have been introduced for the current check function:
<Current Check Tolerance Band> (command current)
<Program Number, Previous Check> (actual current)
Secondary Current, Previous Check> (actual current)
Primary Current, Previous Check> (actual current)
CAUTION!
Make sure that the electrode gun is properly closed. Otherwise, there is a danger of
welding splashes!
Prerequisites:
-
Standard current scaling for the respective electrode must have been per-
formed previously.
-
The spot table must have been saved in the weld timer and the respective
programs must have been configured.
