2. Error output function
When the error output specification function has concluded that the equipment has an error, it
halts the temperature controls and maintains the control output at a previously specified value.
There is an error in PV if any of the following conditions occur:
burnout upper limit / burnout lower limit / underage (PV< -5% FS) / overage (105% <PV)

4. Ramp SV function
The ramp SV function suppresses a sudden change in SV (step change) when changing SV .It
allows SV to change smoothly according to the set slope of temperature per unit of time.This
smooth SV change allows you to minimize the effect of the change on controls.
You can set both inclining temperature and declining temperature slopes, and choose from
"minutes" or "hours" for the time units.
You can also choose for the SV display to show the current value or the target value during
ramp SV.

set values have been previously decided.
