In this appendix, it is described how to replace a CU1-unit by a new one, and how
to enter existing supervisory values into the new unit. The new CU1-unit is calibrated

2 Switch the power off and replace the CU1 with a new one.

4 Carry out the normal startup routine to check that the setup routine was
carried out correctly.
5 Measure the load sensor voltages between CU1:2 and CU1:3 with the 0 %
and 100 % loads and write down the load sensor voltages on the CU1 control
page.
6 Update the old supervisory values from the old CU1 into the new one:
a) Change the CU1 into the beginning of the programming and
controlling mode by entering value 1-630 as password_1.
b) Enter value 2-000 as password_2.
c) Enter value 3-511 as password_3 and select function SUP5.
