SELECTION OF THE WORK PROGRAM
• = input active
The programs that can be selected are 31, when using input REC5 as additional recall input, or 15 if
using input REC5 as parity check. The use of input REC5 as parity check is activated in the
"Installation" Menu (see specific paragraph) in which the type of parity is also selected: Even or Odd.
The parity check consists in checking that the number of activated inputs, for recalling a program, is
even or odd.
Example:
Recall of Prog. N. 06 with even parity check.
To recall program 6 you must activate two inputs, REC2 and REC3, but since parity is odd you must
also activate input REC5 to obtain an odd number of active inputs.
To properly recall the welding programs, either activate the direct recall inputs before the start
cycle signal or simultaneously.
