Maintenance and care
10.3.1 Steps for replacing the I/O module
When the I/O module is dismantled, advanced electronic components are accessible.
Protect these from electrostatic discharge, contamination and moisture.
If possible use anti-static floor mats and workbench covers.
When working on the S3000, touch a bare metal surface from time to time to discharge
static charging of your body.
Only remove the components of the S3000 from their anti-static packing immediately
prior to installation.
Note that no liability can be accepted for damage caused by electrostatic discharge.
The I/O module is only allowed to be replaced by qualified safety personnel in a clean
environment.
Mount the I/O module as per the following instructions to ensure that the housing is
sealed to IP 65.
How to replace the I/O module:
Disconnect the system plug and remove the S3000.
Take the S3000 to a clean place (office, repair shop or similar).
First clean the outside of the S3000.
This prevents foreign bodies entering the device when it is opened.
Undo the fixing screws for the I/O module.
Take hold of the I/O module with one hand at the recess for the connector to the system
plug.
With the other hand take hold of the I/O module at the dismantling aid on the underside
of the device.
Pull out the I/O module parallel to the mounting shaft.
Remove any contamination from the sealing surface and the mating surface for the
sensor head. For this purpose if possible use a plastic cleaner that does not leave
residues (see section 13.3 “Accessories/spare parts” on page 163).
Remove the I/O module from the packaging, ensure that you take adequate ESD
protection measures during this process.
Check the surfaces for cleanliness and the seal for correct seating
Insert the I/O module in the mounting shaft parallel to the rear of the sensor head.
During this process use the three surrounding sides of the shaft for orientation.
Guide the I/O module along these surfaces to the connector. During this process slide
the I/O module parallel to the rear of the sensor, avoid tilting. The I/O module can be
connected without the need to apply force.
When the I/O module is flat against the rear of the sensor head (distance approx.
1 mm), tighten the screws in stages, diagonally, to 10 to 12 Nm.
Re-commissioning the S3000:
Correctly re-mount the S3000 (see chapter 5 “Mounting” on page 66).
Connect the S3000 system plug.
– If you have replaced the I/O module for the same I/O module variant, after power up
the S3000 automatically reads the saved configuration from the system plug (see
section 9.3 “Re-commissioning” on page 124).
– If you have replaced the I/O module with a different I/O module variant (e.g. Standard
with Advanced), you must perform an initial commissioning (see section 9.1 “Initial
commissioning” on page 120).
