[OUT1 rate-of-change]
For Heating control, if PV is lower than SV, the output is generally turned from OFF to ON as shown in
(Fig. 7.2-2).
If OUT1 rate-of-change is set, the output can be changed by the rate-of-change (Fig. 7.2-3).
This control is suitable for high temperature heaters (which are made from molybdenum, tungsten or
platinum, etc., and used at approx. 1500 to 1800 ) which are easily burnt out from turning on
electricity rapidly.
