Replacement of Components and Modules
20.2. Changing the electronics module
NOTE!
Electrostatic sensitive components/modules!
• The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact
with electrostatically charged persons or objects may be hazardous to these components. In the worst case
scenario, they will be destroyed immediately or will fail after start-up.
• Observe the requirements in accordance with DIN EN 61340-5-1 to minimize or avoid the possibility of damage
caused by sudden electrostatic discharge!
• Also ensure that you do not touch electronic components when the supply voltage is on!
Removal procedure:
→
Open the housing following the instructions in Chapter "8. Opening and Closing the Housing".
→
If necessary, mark the electrical connections to ensure correct assignment during reinstallation!
→
If required, note the position of the DIP switches for the set color code and the DIP switches (8-switch block)
on the DeviceNet electronics module for baud rate and address. On the AS-i electronics module, note the AS
interface address and the jumper positions (power supply to AS interface).
→
If required, read out and note special settings by PC software.
→
Loosen all electrical connections on the electronics module (plug-type connections, screw-type terminal
connections).
→
Loosen the screw-type connection (Torx T10 screw) of the electronics module and store the screw in a safe
place.
→
Carefully press the electronics module forwards so that the contact pins on the position measuring system are
exposed.
