4-2 Setting Output Specifications
4-2-1 Control Output Method
The time-proportional output method is used for the control output.
The MV determines the percentage of time that the output is ON during each
control period.
Note Control responsiveness improves as the control period is short-
ened, but if relays are being used for heater control, the relay life-
time will also be shortened so we recommend using a control
period of at least 20 seconds.
Note If the parameter is set to 0, the period will be 0.5 s.
4-2-2 Alarm Outputs (TC2 Units Only)
Output 3 and output 4 from TC2 Units are used to output alarm 1 for the
channel assigned to the TC2 Unit.
Example for the Following Groups
• If alarm 1 for channel 6 turns ON, output 3 from the TC2 Unit with com-
munications unit number 3 turns ON.
• If alarm 1 for channel 10 turns ON, output 4 from the TC2 Unit with com-
munications unit number 4 turns ON.
