adjustment of Z height may be necessary after changing an ink cartridge, due to slight
manufacturing variations between cartridges.
The Z UP and Z DOWN buttons can also be used to move the inker up or down by
depressing and holding down either button. This function is useful to quickly raise inker
Z height when changing cartridges, but great care should be taken not to “run” the inker
down into the wafer surface in this mode.
External Switch Input
There is a second input on the rear of
the unit for use with a foot switch.
Upon activation, the foot switch sends
a > 50mSec switch closure signal
(across pins 1&3) to the controller,
enabling an inking sequence. There is
a 50-millisecond delay between the
end of the sequence and the
recognition of the next switch closure.
No other adjustments or settings need
to be made.
Rear Panel Puff Pulse Selector
In normal operation, after a pause in
inking activity, a “puff pulse” of air is
introduced into the cartridge air line to
keep ink from being drawn back out
of the cartridge’s Teflon tubing by a
vacuum effect, due to valve closure.
This pulse is calculated differently
when using the A4 cartridge, than
when using existing A5-A8 cartridges.
Place the switch in A4 mode when
using the A4 cartridge to place small
dots. When using A5-A8 cartridge
types, place the switch in A5-A8 mode to duplicate the puff pulse operation of the older
350-0018 Motorized-Z pneumatic controller.
