3-5 Setting Output Specifications
3-5-1 Control Period
• Set the output period (control period). Though a shorter period provides
better control performance, we recommend setting the control period to
20 seconds or more taking the life expectancy in the case of relay output
into consideration. If necessary, readjust the control period by trial opera-
tion, for example, when the control period parameters are set to their
defaults.
• Set the control period in the “control period (OUT1)” and “control period
(OUT2)” parameters (initial setting level). Default is “20 seconds”.
• The “control period (OUT2)” parameter can be used only in heating/cool-
ing control.
• Whenever control output 1 is the current output, “control period (OUT1)”
cannot be used.
3-5-2 Direct/Reverse Operation
• “Direct operation” refers to control where the manipulated variable is
increased according to the increase in the process value. Alternatively,
“Reverse operation” refers to control where the manipulated variable is
decreased according to the increase in the process value.
For example, when the process value (PV) (temperature) is lower than the set
point (SP) (temperature) in a heating control system, the manipulated variable
increases by the difference between the PV and SP values.
Accordingly, this becomes “reverse operation” in a heating control system, or
alternatively, “direct operation” in a cooling control system.
• Direct/reverse operation is set in the “direct/reverse operation” parameter
(initial setting level). The “direct/reverse operation” parameter default is
“reverse operation”.
