OUT1 rate-of-change
• Sets changing value of OUT1 MV for 1 second.
Setting the value to 0 disables this function.
• About OUT1 rate-of-change:
For Heating control, if PV is lower than SV, OUT1 MV is generally turned from
OFF to ON as shown in (Fig. 8.3-3).
If OUT1 rate-of-change is set, OUT1 MV can be changed by the rate-of-
change as shown in (Fig. 8.3-4).
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.
• Setting range: 0 to 100 %/second
Not available if OUT1 is in ON/OFF control.
