10. Maintenance
Generally, the Double Sheet Detector R1000 UDK20 requires no special or regular maintenance.
If new types of sheet metal and dimensions are to be processed, then a new teach-in for new programs to
be stored is necessary, see also section 7.7.2 "Program parameter 8 - Teach-in".
In the following cases a new teach-in for all programs becomes necessary:
•
If a sensor exchange was not done according to the instructions in the following section "Sensor
exchange"
Note: Changes in metallic sensor brackets can change the measured value. Sensor
brackets made of metal with higher conductivity extract more energy from the sensor
(and vice versa) due to the eddy current effect. Thus the stored programs lose their
validity.
10.1 Sensor exchange
In order to continue using the taught programs, the following must be observed:
•
Before the sensor is removed, its installation position must be exactly documented. This applies
especially to the installation position with regard to the measuring axis.
•
The original installation position in all directions has to be restored. This applies especially for the
gaps to the sheet.
Attention: If the original sensor positions cannot be restored, then the teach-in has
to be repeated for all programs.
After a sensor exchange the zero adjust must be made again. Procedure:
For a 1P-control unit with one sensor:
1.
Ensure that no sheet is in front of the sensor
2.
Press the MENU key, select "change" and confirm with ENTER key
3.
Enter the password
Change to "program parameter" and confirm with ENTER key
4.
5.
Ensure that no sheet is in front of the sensor
6.
Change to "zero adjust", select "on"
7.
Control unit shows "remove sheet", Confirm with ENTER key
8.
Control unit shows "zero adjust: active", then "zero adjust: off"
9.
Leave programming with MENU key
