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 dispense with fuses en-
tirely. 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.
