The system will not start running until all the errors detected at the power
supply have been eliminated.
To eliminate these errors, their cause has to have disappeared and, then
an “error reset” must be carried out. This “RESET” may be activated from
the RESET button that the power supply has on top of the status display
and the switches for selecting the DC BUS voltage.
