ceed, the red light signals an error (Error code 3). If the process was success-
ful the green light is shown.
The process is controlled in the welding segment either with the current for
normal steel or with a lower current for high strength steel. The decision cri-
terion has been created in the segment "pre pulse". The process is not, in op-
position to usual procedures, time- oriented. The energy at the electrode caps
is balanced and compared with the energy- target value in the database. With
the achievement of the target energy within the presetted critical time the
process ends.
During the welding, following signals could appear:
a) green; code 10 (the resistance is between the reference resistance
and the presetted maximum resistance)
b) green after yellow; code 11 (resistance is higher than the
presetted maximum resistance)
If the resistance by reaching the target energy lower than the reference
resistance, there is a bypass on the workpiece and the virtual machine
calculates the seize of the bypass and add the correct energy value.
a) green after yellow; code 12 (energy was added because of a
bypass)
b) green after yellow; code 13 (process ended without adding
energy)
c) green after yellow; code 14 (process ended with adding energy)
The segment post heating stopps the process. The currentflow- and time
are different at normal- and high strength steel.
Status signals ERROR x, CODE y; are displayed in the debugger mode,
af_hv09 ( cell 181 with VM1 ).
