Troubleshooting
General The digital power sources are equipped with an intelligent safety system. This
means that apart from the fuse for the coolant pump, it has been possible to dis-
pense with fuses entirely. After a possible malfunction or error has been
remedied, the power source can be put back into normal operation again without
any fuses having to be replaced.
