Maintenance
Note
Don’t open the device. The producer warranty will be forfeited if the device is opened.
Cleaning other optical surfaces:
¾
If an external reading pulse generator with a sensor (e.g. photoelectric reflex switch) is
used, make sure to clean the relevant optical surfaces (
). Contamination on
these surfaces can cause switching errors.
Incremental encoder
If an incremental encoder is used, check the correct position on the conveyor.
¾
Ensure that the incremental encoder always contact the conveyor so that the friction
wheel turns without slipping.
7.2
Maintenance
The ICR does not require any maintenance except the described cleaning measures.
Its self-monitoring functions ensure fault-free operation over long periods of time.
Any faults or malfunctions are listed as error codes in the error memory. They can be
requested using command strings
.
7.3
Disposal
Irreparable devices or devices that are no longer required are to be disposed of in an
environmentally-friendly manner:
1.
Always observe the applicable national waste disposal regulations.
2.
Remove the ICR housing.
3.
Remove the electronic modules and the connection cable.
4.
Remove the glass panel from the reading window and send it to be recycled.
5.
Send the chassis and cover (zinc
)
to be recycled.
6.
Send the electronic modules and connection cable for disposal as special waste.
At present SICK AG does not take back devices which have become unusable or
irreparable.
