Preventa XU - XUSLBR5A0520 has the error code 23, which it´s not at user´s manual. What´s the meaning of this error and how to solve it?

The error code 23 or starting by 2* cannot be displayed on the XUSLB/D type 4 curtains. Please check which is the correct error and use the XUSLB/D user manual to diagnostic and solve the issue in the application. Probably that the customer sees "23" error code instead of "32" error code on the IBI's (individual beam indicator).
