2.6. Valve control
iPAK2 has eight discrete outputs (AV1 – AV8) that can be operated independently during a weld
sequence. The valves are categorised as WAV, MOTOR
1
or AUX valves.
 A WAV valve turns on at start of sequence and turns off at the end of the Hold interval.
 A MOTOR valve turns on after the 2
nd
stage test (see Configuration section), and turns
off at the start of the Hold interval.
 An AUX valve may be programmed to come on during any interval of the weld
sequence, including the Off time in repeat or roll-spot mode.
