8. SETTING HARD STOPS (Figures 4-7
and
4-8)
-
The two hard stops on the turntable chassis are
adjustable to align mounting plate receiver holes with
the locking pin for securing mounting plate position
after clockwise and counterclockwise rotation.
To adjust hard stops, proceed as follows:
WARNING: MOVING PARTS can cause serious
njury.
•
Keep clear of moving parts and pinch points.
Turntable operation is required to properly adjust hard
stops.
1.
Loosen bolts that secure adjustment plate to
hard stop mounting plate on both sides of turn-
table.
2. Loosen jam nuts on adjusting screws at rear of
base blocks.
3.
Manually
run the program for rotating mounting
plate
using the
BLOCK FORWARD
CON-
TINUOUS mode.
4.
Check mounting plate receiver hole position at
the locking pin location to determine direction of
hole misalignment.
IMPORTANT:
Hard stop adjustment for aligning
receiver holes with locking pin is correct when knocker
block moves approximately 1/32 in. (0.8 mm) away
from hard stop as locking pin enters receiver hole to
secure
mounting plate after
clockwise
or
counterclockwise rotation. If adjustment of hard stops
does not align receiver holes with locking pin, check for
proper index rotation of mounting plate (see Section
4-17 C).
5. Adjust hard stop for the side where knocker
block is located to correct receiver hole misalign-
ment.
