Steps for replacing the I/O module
Important information
NOTICE
When the I/O module is dismantled, advanced electronic components are accessible.
No liability can be accepted for damage caused by electrostatic discharge.
b
Protect the components from electrostatic discharge, contamination and moisture.
b
If possible use anti-static floor mats and workbench covers.
b
When working on the device, touch a bare metal surface from time to time to dis‐
charge static charging of your body.
b
Only remove the components of the device from their anti-static packing immedi‐
ately prior to installation.
NOTICE
•
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 IP65.
Approach
1.
Disconnect the system plug and remove the safety laser scanner.
2.
Move the safety laser scanner to a clean location (office, maintenance shops or
similar).
3.
First clean the outside of the safety laser scanner. This prevents foreign bodies
entering the device when it is opened.
4.
Remove the fixing screws for the I/O module.
5.
Take hold of the I/O module with one hand at the recess for the connector to the
system plug.
6.
With the other hand take hold of the I/O module at the dismantling aid on the
underside of the device.
7.
Pull out the I/O module parallel to the mounting shaft.
8.
Remove any contamination from the sealing surface and the mating surface for
the sensor head. If possible use a plastic cleaner that does not leave residues.
9.
Remove the I/O module from the packaging and take adequate ESD protection
measures during this process.
10. Check the surfaces for cleanliness and the seal for correct seating.
11. 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.
12. Guide the I/O module along these surfaces to the plug connector. During this
process slide the I/O module parallel to the rear of the sensor head, avoid tilting.
The I/O module can be connected without the need to apply force.
13. 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.
Recommissioning the safety laser scanner
1.
Correctly re-mount the safety laser scanner.
2.
Connect the system plug of the safety laser scanner.
✓
If you have replaced the I/O module for the same I/O module variant, after power
up the safety laser scanner automatically reads the saved configuration from the
system plug.
✓
If you have replaced the I/O module with a different I/O module variant (e.g.,
Advanced with Professional), you must perform an initial commissioning.
