When the error is reset, the error information for display usage between the last error reset (or
from when the power was turned on) up to this error reset is discarded.
The error reset is sent to the DC power supply at that time, but if the DC power supply remains in
an abnormal state, the error display will return after being cleared. The monitor display after the
error reset is shown in the monitor type (power/current, SET/voltage) before the error reset.
The error reset method is as follows.
1) From the upstream PLC, input error reset signal high -> low (must continue for 100 ms or
longer)
