Air pressure status list:
Note, ordinary pressure and vacuum value in list are
valid only after sucking material at least one time when running, or it will display
invariable 0; ordinary pressure is the pressure detected before sucking material;
vacuum value is the absolute value of that pressure after sucking minus ordinary
pressure, bigger value indicates better effect, effect is judged by partition the
range of this value;
(4)
MHead 1\2 threshold 1:
I.e. lower limit of vacuum value, no material is
determined if vacuum value is below this value when running, and machine will
retry, otherwise indicates material is sucked;
(5)
Nozzle 1\2 threshold 2:
I.e. upper limit of vacuum value, bad material is
determined if vacuum value is below this value when running, and material will be
thrown away, otherwise indicates good suction and material will be mounted;
Note, threshold 1 must smaller than threshold 2, threshold 2 must smaller than
detected vacuum value when suction OK, threshold 1 must greater than detected
vacuum value when no material. Recommended values: threshold 1 must less than
detected vacuum value when suck empty material; threshold 1 less 0.2 than threshold 2,
