Proximity Switch Location & Function
INDEX TABLE UP PROXIMITY SWITCH - (Lift “ON” Prox)
This proximity switch is mounted to a bracket located in the
middle area of the indexer assembly. The function of this
proximity switch is to signal the PLC that the index table has
reached its fully raised, or print position. A small L.E.D. on
the side of the proximity switch illuminates whenever the
proximity switch senses the proximity of the registration
mounting bracket as the index table raises. (See illustration
at left)
FORK OFF PROXIMITY SWITCH -
This square shaped proximity switch, referred to as the
“Fork Proximity Switch” is used to signal the PLC when the
index capture fork clevis is dis-engaged from the index
table. A small L.E.D. on the switch illuminates confirming
the switch operation and the fork clevis position. The switch
is mounted to the index clevis assembly. (See illustration at
right)

INDEX “ON” PROXIMITY SWITCH -
This proximity switch is referred to as the “Index ON” prox-
imity switch. The function of this proximity switch is to sig-
nal the PLC that the index table is aligned with the print sta-
tions by sensing the index cam follower bearing mounted to
the bottom of the index carousel plate. In addition, this
proximity switch also provides a signal which tells the PLC
that the index table has reached its fully lowered position. A
small L.E.D. on the side of the proximity switch will illumi-
nate when the switch senses the index cam follower bear-
ing. (See illustrations at right)
