+ Set value: Dead band,
–Set value: Overlap band
• Available when Heating/Cooling control output is selected from the Block function
(Console software).
• Setting range: -100.0 to 100.0
( ),
DC current, voltage input: -1000 to 1000 (The placement of the decimal point follows the
selection.)
Output rate-of-change
0 %/second
• Sets the change value of output MV for 1 second.
• Setting the value to 0 disables the function.
Not available if the output is in ON/OFF control.
• Setting range: 0 to 100 %/second
[Output rate-of-change]
For Heating control, if PV is lower than SV, output is generally turned from OFF to ON as
shown (Fig. 8.2-2).
If Output rate-of-change is set, the output can be changed by the rate-of-change (Fig.
8.2-3).
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.
