Operator Controls
Independent Print Start Push Button:
This push button permits manual cycling of a selected print
station. Please note that the
“Single/Double” toggle switch for
the selected print station must be set to either “Single” or
“Double” position in order for the print station to operate. When
the “Single/Double” toggle switch is selected to “Single” the
print head will make one complete flood/print cycle. When the
“Single/Double” toggle switch is selected for “Double” the
selected print head will make two (2) complete flood/print
cycles. The
“Independent Print” push button is also used
during screen frame setup to check registration etc. as follows:
During screen frame installation and setup, place the selected
“Single/Double” toggle switches to the middle or “OFF”
position. Then press the “Print” push button. The index carousel
will raise so that screen registration or placement may be
checked. To lower the index carousel, press the green
“Reset”
push button located at the right of the control panel under the
“Emergency Stop” push button.
Emergency Stop Push Button:
This large, red mushroom-shaped push button is designed to stop
the system operation
only in an emergency situation . Do not use
this push button to stop system operation under normal
operating conditions.
To stop the system in an Emergency situation, press the red
mushroom-shaped button
“In” . This will result in all print
stations shutting down, the retraction of the index fork and shut
down of all system operation. Once pushed
“In” the Emergency
Stop push button will remain locked in this position to prevent any
further operation of the system. To resume system operation once
again, turn the red mushroom shaped Emergency Stop Push Button
clockwise one quarter turn, until it pops out then press the green
“Reset” push button.
Reset Push Button:
The green colored “Reset” push button is pro-
vided to “reset” the control system logic in the
event of a Emergency Stop command or activa-
tion of one of the safety devices. This push but-
ton also is used to lower the index table during
set-up procedures.
Single/Double Selector Switch:
The “Single/Double” toggle switch commands the
selected print head to print either one complete
flood/print cycle or two (2) flood/print cycles. Generally,
this switch is used when it is desired to deposit a thicker
coating of ink, such as in flash cure applications, or
whenever increased ink opacity is desired. Each individual
print head in the system may be set independently for
either
“Single” or “Double” print mode using these toggle
switches.
NOTE: When this toggle switch is selected for the
middle, or “OFF” position, the particular print station
will not operate.
