4 displays are BCD-coded in multiplex technology controlled
 Program number display (with one dot) only if no fault- or electrode status
message is active.
 Status- and fault display refer following text: diagnosis for 7-display version 2
Diagnosis for 7-display version 2
Additional to the both displays of version1 come two further displays, which
show for the both guns the selected welding program number.
All 4 displays are controlled in multiplex technology, that means the displays
are refreshed cyclic.
Therefore are displays with memory necessary. The outputs X21/A05 to A08
are for the selection of the corresponding display.
The both additional displays show the selected welding program number.
They count with operate the belonging "+" respectively "-" key from 1 to 4,
forwards or backwards.
Selected is with Start_1 the welding program 1 to 4 and with Start_2 the
welding program 5 to 8.
After switch on of the welding control both counter stand on "1".
7.1.1 Program selection and electrode in dependence of the input
signal
Special features with function: Program selection and electrode in dependence of
gun code inputs and the input „ Program counter active ".
Control preferably for suspended station with 2 starts / 2 electrodes and 4
programs.
 The electrode assignment is done after memory delete as following:
program 1 / 2 is assigned to electrode 1,
program 3 / 4 is assigned to electrode 2.
 Program selection, see following table: Program selection version 1

Note
The inputs: Start 1 and Start 2 are locked against each other.
 The electrode maintenance concept respect the separate inputs and outputs
for electrode number: 1 and electrode number: 2.
