Step 7 - Wind Direction Test
The CX-1102 will display automatically System Setup Wind Direction\Page 7.
Setup State {MP-59} will equal 8.
Setup State {MP-59}
Wind State {MP-48}
WindCO Volts {MP-37}

WindEncPlrty {CP-264}
Wrap Polarity {MP-70}
Sig Polarity {MP-71}
Wind Dirn {MP-61}
NOTE: The Help key accesses the Help screen and gives you a brief description of the parameter or
subject that is highlighted (active) on the screen. Press the Help key again to return to the previous screen.
REMINDER: The Wind Under Wrap input MUST be shorted to common if the wind axle will have web
material fed onto the roll from the bottom rather than the top of the roll. This needs to be done so the
proper polarity can be determined in the following step.
If the wind axis is under CX-1102 control:
This test sets the Control Output and Encoder polarities so a positive command equals forward direction.
NOTE: The Keypad will be disabled while this test is moving the wind axis.
The CX-1102 will now display “KeyLk” (flashing) in the lower center of the display.
NOTE: The web must be threaded into the machine (and dancer), and the dancer in the (relaxed) full
position with the web material tight against the dancer.
WARNING
Prepare the machine for motion.
Alert everyone present.
1) Momentarily close the KeyLk input. The CX-1102 will send a positive command to the Wind axis, for
forward direction. The CX-1102 will montior the Dancer content for movement away from the Full position.
If the Dancer does not move after X number of rotations of the Wind roll, the Wind axis is stopped.
If WindCO Mode {CP-285} is set to Unipolar, this test Fails.
If WindCO Mode {CP-285} is set to Bipolar or Unipolar Reversing, WindCOPolarity {CP-287} and
WindEncPlrty {CP-269} are changed, and a positive command is issued to the Wind axis again
for forward rotation (maximum of 2X number of rotations). The CX-1102 will montior the Dancer
content for movement away from the Full position.
