The Challenger Series II is a blend of exciting technology
that incorporates microprocessor controls and a unique
servo driven index system that offer the ultimate in maxi-
mum production efficiency. The following is a description of
a single cycle operation of your new press, followed by a
description of all control functions.
Cycle Sequence -
Position the table so that the Index “On” Proximity Switch,
located on the base of the machine, is “On” . Release the
Emergency Stop Button and press the green “Reset” but-
ton. The index fork (clevis) will cycle in and engage one of
the index cam followers located on the bottom of the index
table. Turn one print station switch
“On” by placing the tog-
gle switch to the “Single” print position. Depress the mode
switch to “Manual” and release.
The press will perform the following functions:
• The index servo drive assembly will rotate
the carousel until the next cam follower
again activates the index
“On” proximity
switch.
• Simultaneously, the flood stroke of the print
station is started and completed.
• Next, the carousel is lifted into the print
position and activates the Table Proximity
Switch; this starts the print stroke. At the
same time, the index servo drive is
returning to the start or standby position for
the next cycle.
• At the completion of the print stroke, the
carousel lowers with the cam follower
settling into the index fork (clevis) ready for
the next cycle.
The combination of full microprocessor controls—and the
use of proximity switches to indicate the position of all com-
ponents at any time—permits our Engineers to provide you
with a “plain language” self-diagnostic system unavailable
on any competitive semi-automatic textile press.
Control Panel Functions:
The Main Control console for the M&R Challenger Series II
contains all controls for operation of the entire system. The
individual controls and their functions are described as fol-
lows.
Main “ON/OFF” switch location. (See figure 1)
Print Station Control Switches:
To the extreme left of the Main Control panel, the individual
Print Head control switches and push buttons are located.
These include
“Independent Print” , “Single/Double” print
stroke and “Front/Rear” print carriage stop. (See
illustration on page 25)
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. (See illustration on page 25)
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.
