Example 2: P1210 = 7 and error of longer duration
When using setting 1210 = 7, note the following:
a) If, during a restart attempt of the SED2, the ON command is withdrawn, the SED2 stops immediately and
“r oFF“ is constantly displayed. When the ON command is active again, the restart process is resumed.
b) If an error occurs, “r oFF“ might appear on the display for a short moment (although the ON command is
constantly present). In this case, the short display of “r oFF“ is instantly replaced by the static display of
“buSY“, and the restart process is resumed.
