IntheManualmode(includingO/S),thevalueofOUTintheAutomodejustbeforeachangeto
the Manual mode is held, or the value written to OUT is output.
If the mode is switched from Manual to Auto, the output value of OUT that is linearly changed with
respect to the value of PRE_OUT for time set by BAL_TIME is output. The PRE_OUT always
indicatestheresultsofcalculation.AfterelapseofBAL_TIME,OUT=PRE_OUTisestablished.
Note that if the value of BAL_TIME is changed during the linear change of the OUT value, it is not
reected.ThevalueofBAL_TIMEwillbereectedonlyafterthemodeischangedthenexttime.
