DIGITAL OUTPUT
This tab allows you to configure the parameters related to the digital outputs:
QuickTune
QuickTune Mobile
Digital Output tab
•
OUT.A Function:
Allows you to define
out.A
output function: “Off”, “Control Output 1”, “Control Output 2”, “Alarm 1”, “Alarm 2”, “Alarm 3”,
“Alarm 4”, “Timer 1”, “Timer 2” or “Modbus-Coil” (see
section).
•
OUT.B Function:
Allows you to define
out.B
output function: “Off”, “Control Output 1”, “Control Output 2”, “Alarm 1”, “Alarm 2”, “Alarm 3”,
“Alarm 4”, “Timer 1”, “Timer 2” or “Modbus-Coil” (see
section).
7.3.2.3
CONTROL
This tab allows you to configure the parameters related to the control mode:
QuickTune
QuickTune Mobile
Control tab
•
Control Mode:
Allows you to define the control mode: “Manual” or “Automatic” (see
section).
•
Control Action:
Allows you to enable the control logic to be used: “Heating (Reverse)”, which turns on the control output when the PV is below
SP, or “Cooling (Direct)”, which turns on the control output when the PV is above SP. Available only for “Automatic” control mode.
•
Control Hysteresis:
Allows you to define a hysteresis value for ON/OFF control mode (To define an ON/OFF control mode, the
Proportional
Band
parameter of the Tuning tab must be set to 0.0). Adjustable between 0 and the measurement range width of the selected input type.
•
Lower limit of SP:
Allows you to define the lower limit for the Setpoint adjustment. Allows you to define the minimum value of the PV indication
range and limit the SP adjustment of the available
linear analog signal inputs
(0-20 mA, 4-20 mA, 0-50 mV, 0-5 V and 0-10 V).
•
Upper limit of SP:
Allows you to define the upper limit for the Setpoint adjustment. Allows you to define the maximum value of the PV indication
range and limit the SP adjustment of the available
linear analog signal inputs
(0-20 mA, 4-20 mA, 0-50 mV, 0-5 V and 0-10 V).
•
Enables control and controller outputs:
Allows
you to enable control and outputs.
