Index On
Proximity
The
Index On
proximity switch is mounted to the
indexer base and is positioned so that it reads the
cam follower bearings on the carousel plate as the
indexer revolves. When this proximity switch is
actuated, the control system then raises the index
carousel up into the registration forks and print
position.
When the print heads all complete their flood/print
strokes, the index carousel lowers and this
proximity switch again reads the cam follower on
the carousel plate.
When the
Index On
proximity switch reads the
cam follower, the indicator at the right changes to
red. This confirms the correct operation of the
Index On
proximity switch. If the indicator does
not change to red when this proximity switch is
reading the carousel plate cam follower, then the
operation of the proximity switch and/or the switch
cables may be faulty. Inspect and/or replace the
proximity switch and/or cables to correct the
problem.
Lift Up
Proximity
Switch
The
Lift Up
proximity switch is mounted to the
upper indexer print head support and is positioned
so that it reads the index carousel registration cam
follower bearings as they engage in the
registration fork. When this proximity switch is
actuated, the control system then signals the print
heads to begin the print stroke.
When the
Lift Up
proximity switch reads the cam
follower, the indicator changes to red. This
confirms the operation of the
Lift Up
proximity
switch.
If the indicator does not change to red when this
proximity switch is reading the registration cam
follower, then the operation of the proximity switch
and/or the cables may be faulty. Inspect and/or
replace the proximity switch and/or cables to
correct the problem.
Fork Off
Proximity
Switch
The
Fork Off
proximity switch is mounted to the
index drive engagement fork assembly and is
positioned so that it reads the index fork clevis
when the index engagement fork is retracted.
When the
Fork Off
proximity switch reads the fork
clevis, the indicator changes to red. This confirms
the operation of the
Fork Off
proximity switch.
If the indicator does not change to red when this
proximity switch is reading the fork clevis, then the
operation of the proximity switch and/or the cables
may be faulty. Inspect and/or replace the proximity
switch and/or cables to correct the problem.
