4.2 Replacing Spare Parts

Service Manual SIPLACE LDU-X Linear Dipping Unit 11/2017 43

► Loosely screw the motor into place

with the 4 screws and washers. Take

care to align the motor properly. To do

this, make sure that the rectangular

part of the housing at the rear of the

motor, on the right-hand side, points

inwards.

► Once the motor has been correctly

aligned, tighten the 4 screws. Make

sure that the alignment is not changed

while you tighten the screws.

► Before assembly, align the motors

and couplings so that the flattened

side of the motor shafts (1) and one of

the two grub screws (2) for the coup-

ling point upwards.

 NOTICE!

A reliable connection is only formed if

one of the grub screws touches the

flattened side of the motor shaft!

► Carefully push the motor shafts into

the couplings.

► Align the motors and couplings so that

there is a gap of around 1 mm

between the couplings and the motor

mount.

► Tighten the grub screws. Make sure

that the set gap does not change dur-

ing tightening.

 CAUTION!

Make sure that the coupling does not

grate against the motor mount!

► Refit the motor fixing plate (see4.2.29.6 "Fitting the Motor Mount" [}61]).

► Refit the base plate (see 4.2.29.7 "Fitting the Base Plate" [}61]).

► Restore the press-fit connections for the LDU-X control board, reassemble and refit the LDU

base (see 4.2.29.9 "Assembling and Fitting the LDU Basis" [}63]).

► Fit the side covers (see 4.2.29.10 "Fitting the Side Covers" [}65]).

CAUTION

► Whenever you loosen the couplings, you will need to remeasure the positions of the

axes.

► Whenever you dismantle the base unit, you will need to level the LDU-X out again on

the machine (see operating instructions)!

4.2.20 Replacing the proximity switch

Overview

Proximity switch assembly [03068930-xx]

1. Proximity switch

2. Cable to LDU-X controller

Equipment required

●

Standard tools

●

Allen key, sizes 5, 3 , 2 and 1.3

●

Spare part: proximity switch assembly [03068930-xx] with 4 adhesive labels

NOTICE

Adhesive label

There is only one model that is used for all 4 proximity switches in the LDU-X. The switch

can be clearly marked with the labels provided.

Removal

► Remove the side covers (see 4.2.29.1 "Removing the Side Covers" [}57]).

► Remove and dismantle the base unit, separating it into top and bottom sections and unplug all

press-fit connections to the LDU-X control board (see 4.2.29.3 "Removing and Dismantling the

LDU Basis" [}58]).

► Dismantle the base plate of the upper section of the base unit (see 4.2.29.4 "Removing the

Base Plate" [}60]).

1. Proximity switch RLIM1 (fitted to

mounting plate (5))

2. Proximity switch LLIM2 (Z axis up)

3. Proximity switch RLIM2 (Z axis down)

4. Proximity switch LLIM1

5. Mounting plate for proximity switch (1)

6. Proximity switch dip plate

7. Proximity switch tray

To replace (1):

► Loosen the screw fastening the

mounting plate (5), on which the prox-

imity switch is fitted.

► Loosen the screw fastening the prox-

imity switch and remove the switch

from the plate.

To replace (2), (3), (4), (6) or (7):

► Loosen the screw fastening the prox-

imity switch to be replaced.

► Make sure you know in which cable

duct the cable for the defective prox-

imity switch is run.

► Now loosen the relevant fastening

screws (1) or (2).

► Carefully pull the cable of the defect-

ive proximity switch out of the cable

duct and remove the proximity switch

concerned.

Installation

CAUTION

Important installation instructions

► Before fitting, mark the sensor cable with the relevant label (see old cable), so that this

can be clearly identified.

► When fitting the sensor, make sure that this lies flush against the respective edges.

► Installation is performed by following the above instructions in the reverse order.
