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.
X Restore the electrical connection and fix the connection cable into place.

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.

Settings
X Check the function and correct position of the reference sensor. The sensor must trigger when the
catch actuator is just below the sensor. (Reference point).
X To do this, open the SITEST main view and select the function=>
SITEST Settings
.
X In the input area
Axis,
select the button
Feed axis
.
X In the input area
Travel range
select the button
Reference bero
.
The feed axis will be moved so that the catch actuator switches the reference sensor.The reference
point will be calculated.
In the SITEST main view, function=>
SITEST inputs/outputs 1,
the display
Reference sensor,
feed axis
will be activated.
A dialog box will open and the calculated reference point will be shown.The permissible limits
(minimum/maximum position) will also be shown.The reference point must be within these limits.
X Check the permissible limits against the value actually measured.
X If necessary, correct the mechanical position of the reference sensor and repeat the measurement
procedure.
X If the value is within the permissible limits, save the data by clicking on
Accept
.
X Seal the two mounting bracket fastening screws with locking varnish.
X Insert the connection cable into the ferrite core
(one loop).
X Press the two halves together so that the
fixture engages.
