A2 type selection
• Selects an A2 type.
• Available only when A2 (option) is added
• Action selection and default value are the same as those of A1 type selection.
A1 action Energized/Deenergized selection
• Selects Energized/Deenergized status for A1.
• Not available if No alarm action is selected during A1 type selection
• Energized:
A2 action Energized/Deenergized selection
• Selects Energized/Deenergized status for A2.
• Not available if No alarm is selected during A2 type selection or if A2 (option) is not added
• Action selection and default value are the same as those of A1 action Energized/
Deenergized selection.
A1 hysteresis setting
• Sets hysteresis for A1.
• Not available if No alarm action is selected during A1 type selection
• 0.1 to 100.0 ( )
For DC input, 1 to 1000 (The placement of the decimal point follows the selection)
A2 hysteresis setting
• Sets hysteresis for A2.
• Not available if No alarm is selected during A2 type selection or if A2 (option) is not added
• Setting range and default value are the same as those of A1 hysteresis setting.
A1 action delayed timer setting
• Sets action delayed timer for A1.
When setting time passes after the input enters alarm output range, the alarm is activated.
• Not available if No alarm action is selected during A1 type selection
• 0 to 9999 seconds
A2 action delayed timer setting
• Sets action delayed timer for A2.
When setting time passes after the input enters alarm output range, the alarm is activated.
• Not available if No alarm is selected during A2 type selection or if A2 (option) is not added
• Setting range and default value are the same as those of A1 action delayed timer setting.
Direct/ Reverse control action selection
• Selects either Reverse (Heating) or Direct (Cooling) control action.
• Reverse (Heating):
AT bias setting
• Sets bias value during PID auto-tuning.
• Not available if input type is DC current or DC voltage.
• 0 to 50
Setting item not used: This item is indicated when Serial communication (option) is
Output status selection when input abnormal
• Selects the output status of OUT1 and OUT2 (option) when DC input is overscale or
underscale. See "Input abnormality indication" on pages 17, 18.
• Available only for DC current output with DC input
• : OFF(4mA) or OUT1(OUT2) low limit
: Outputs a value between OFF(4mA) and ON(20mA) or between OUT1(OUT2)
low limit value and OUT1(OUT2) high limit value, depending on a deviation.
OUT/OFF key function selection
• Selects whether OUT/OFF key is used for control output
OUT/OFF function or for Auto/Manual control function.
•
ARW function
ARW (Anti-reset windup) prevents overshoot caused by the integral action. The smaller the ARW value, the less
the overshoot caused by the integral action in the transition status, however it takes time until stabilization.
Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at a location where control
is desired, the sensor measuring temperature ma y deviate from the temperature in the controlled
location. When controlling with plural controllers, the accuracy of sensors affects the control. Therefore,
sometimes the measured temperature (input value) does not concur.
In such a case, the control can be set at the desir ed temperature by adjusting the input value of sen sors.
