Mounting Instructions - Sony DK812AFR Bedienungsanleitung

2. Mounting Instructions

. If excessive torque is applied on the spindle when screwing in the feeler, the internal
mechanisms can be damaged. Therefore, screw in the feeler with your hands, and never
use a tool.
Except when using a flat feeler, it is recommended to either attach the supplied spring
washer (nominal size: 2.5) or use a screw lock to prevent loosening of the feeler (tightening
torque reference value: 0.05–0.06 N·m).
. The recommended dimension for the measuring unit mounting hole is ø9.7 ±0.15 mm
(0.38" ±0.006" dia.).
. The mounting plate thickness is as follows.
DK812F Series: 6 to 11 mm (0.24" to 0.43")
. The mounting parallelism affects the measuring accuracy. The mounting plate parallelism
and the squareness to the measuring surface should be held within 0.02 mm/14 mm
(0.0008"/0.55").
. Be sure to use the supplied tightening nut, wave washer, clamp spanner and pin to mount
the measuring unit (Fig. 1).
Note
The tightening torque should be roughly that needed to completely flatten the wave washer.
Recommended tightening torque:
Maximum tightening torque:
. Fix the cable in a suitable position to prevent possible cable breakage. Never handle the
cable by forcibly pulling or bending it. (Inside bend radius 40 mm/1.57" or more)
. If the spindle is to be fixed to the machine, use coupling DZ-191 which is optionally
available. Refer to the DZ-191 Instruction Manual regarding the mounting procedure.
. Use the fitting to be attached to the measuring unit as shown in Fig. 2. Especially, the
length of the M4 screw section to be inserted into the measuring unit should be 4.5 mm
(0.18") or less. If the screw is too long, the measuring unit may be damaged.
. After the stem is secured, do not apply force in the rotational direction. This could cause
a failure.
