 Switch the connected M4000
off for at least 1 minute and
back on again.
If the error continues to occur:
 Check the connection to the
M4000 connected. The UE403
switching amplifier receives it
voltage supply from the ESPE
connected.

or
 Check the connection to the
M4000 connected for short-
circuits or cross-circuits.
 Check the voltage supply for
overcurrent.
 Switch the connected M4000
off for at least 1 minute and
back on again.
If the error continues to occur:
 Replace the UE403 switching
amplifier.
Internal error of the
UE403
 Carry out an extended
diagnostics with the aid of the
CDS.
If an internal error is diagnosed:
 Replace the UE403 switching
amplifier.
9.4 Extended diagnostics
The CDS software (Configuration & Diagnostic Software) supplied with the M4000
Advanced multiple light beam safety device contains extensive diagnostic facilities. It
allows you to narrow down the problem if the error is non-specific or if you experience
usage downtime problems. Detailed information to be found …
• in the online help function of the CDS (Configuration & Diagnostic Software).
• in the user manual for the CDS.
How to conduct an extended diagnostics of the UE403:
 Connect the PC/Notebook in which the CDS has been installed to the UE403 switching
amplifier or to the M4000 Advanced.
 Carry out a diagnostics on the M4000 Advanced receiver.
