3.6.3 Replacing the WPTC Lock Sensor Closed [03047285-xx]

Settings

X The sensor must be fitted so that it switches reliably when the locking strip (5) is closed.

X Close and open the locking strip (5) manually. The sensor must switch when the lock is closed.

X The LED on the sensor will show the status:

 LED shines = switched

 LED does not shine = not switched.

X Use SITEST to check whether the correct output was switched.

X To do this, open the SITEST main view and select the function=>

SITEST inputs/outputs 1

 The display

WPTC lock sensor closed

must be active.

X Open the lock.

 The relevant display must be off.

Spare part

 Anti-twist lock proximity switch for magazine

carrier [03047285-01]

Overview

1. Reference sensor, feed axis

2. Feed axis limit switch on tower side

3. WPTC lock sensor closed

4. Ferrite core for EMC interference suppression

at feed axis reference sensor

Removal/installation

X Loosen the two fastening screws (1) on the

sensor.

X Watch the plate beneath (3). Make sure that it

does not fall out and get lost.

X Loosen the cable clamps and remove the

cable ties.

X Unthread the connection cable as far as the

control unit back plane and unplug it from the

terminal strip.

X Fit the sensor so that the sensor surface (4)

points to the locking strip (5).

X Align the sensor parallel to the mounting

bracket (2). Do not dismantle the mounting

bracket.

X Restore the electrical connection and fix the

connection cable into place.

3.6.4 Replacing the WPTC Present in Tower Sensor [03047284-xx]

Settings

X Check the sensor function.

X To do this, push a waffle pack tray carrier (WPTC) by hand into the tower. The sensor must switch

when the waffle pack tray moves past it.

X Move the waffle pack tray back and forth inside the tower guidance. The sensor must switch reliably.

X Move the waffle pack tray to the right and left inside the tower guidance. The sensor must recognize

the WPTC reliably. The LED on the sensor must shine continuously.

X The LED on the sensor will show the status:

 LED shines = switched

 LED does not shine = not switched.

X Use SITEST to check whether the correct output was switched.

X To do this, open the SITEST main view and select the function=>

X Remove the waffle pack tray.

 The relevant display must be off.

sensor mounting bracket (2).

X Loosen the cable clamps and remove the

cable ties.

X Unthread the connection cable as far as the

control unit back plane and unplug it from the

terminal strip.

X Fit the sensor so that the sensor surface (4)

points to the side.

X Align the sensor parallel to the mounting

3.6.5 Replacing the Reference Sensor, Feed Axis [03047273-xx]

Installation

X Loosely screw the reference sensor onto the mounting bracket.

X Note the installation position. The sensor surface must point downwards.

X Run the connection cable through the feed-through hole in the mounting bracket. This cable feed-

through hole serves as a strain relief for the connection cable.

X Fit the mounting bracket with the two fastening screws.

X Leave a sufficiently large loop of cable, so that you can fit the cable in the ferrite core.

X Align the reference sensor parallel to the top edge of the mounting bracket and tighten the two

fastening screws on the reference sensor.

Spare part

 Reference point proximity switch for feed axis

[03047273-01]

Overview

1. Reference sensor fastening screws

2. Mounting bracket

3. Actuator

4. Ferrite core for EMC interference suppression

at feed axis reference sensor

5. Cable feed-through hole on mounting bracket

Removal

X Loosen the two screws (1) fastening the

proximity switch mounting bracket (3).

X In order to remove the cable at the cable feed-

through hole (5), you need to also remove the

mounting bracket (2).

X Loosen the two screws (1) sealed with locking

varnish, which fasten the reference sensor

mounting bracket.

X To do this, you need to push the feed axis

toothed belt (2) a little to the side, so that you

can reach the two fastening screws (1) . Make

sure that the toothed belt is not buckled or

damaged.

X Remove the connection cable at the cable

feed-through hole (3) on the mounting bracket

(4).

X Open the ferrite core (5) at the fixtures

provided, with the help of a screwdriver.

X Unthread the cable clamp and remove the

ferrite core. Keep these in a safe place for later

installation.

X Unthread the connection cable as far as the

control unit back plane and unplug it from the

terminal strip.
