<Reduced Current Scaling>
With this process, the primary current is scaled (adjusted) in the timer to the secondary
current.
The process may be initiated e.g. following the replacement of electrodes by the RC con-
trol setting the
<Reduced Current Scaling>
signal.
Sequence of Reduced Current Scaling:
Prerequisites:
-
Automatic current scaling for the respective electrode must have been per-
formed previously.
Sequence:
-
The electrode must be selected in the I/O field.
-
The gun assigned must be closed.
-
The
<Reduced Current Scaling>
input signal must be set.
Now, the timer is in
<Reduced Current Scaling>
mode. No starts or pro-
gram selections entered in the I/O field will be accepted.
This sequence is the same as the sequence of standard current scaling.
However, there is no external weld current meter required because only the
primary and the secondary currents are measured. In this case, the secon-
dary current is the reference current to which the primary current is scaled.
-
Upon correct completion of the reduced current scaling process, the
<Cur-
rent scaling/check finished>
signal becomes high and is held until the
<Reduced Current Scaling>
input signal is reset.
Current scaling involves the re-determination of 1 value.
Toroid sensitivity: Scaling of the primary current to the secondary current scaled pre-
viously. This value is shown under
Basic Setup - Electrode Setup
in the BOS.
You can view the results of the last scaling operation for the respective electrode in the
”Scaling Results” window under the ”
Electrode Setup
” window in the BOS. Standard scal-
ing results will be overwritten.
No WC signal is output during a reduced current scaling operation.
If an error occurs:
The notes under ”Current Scaling” apply correspondingly.
