Smart Positioner YT-3100 Product Manual Auto Calibration 1 (AUTO 1) 9.6.2 AUTO 1 is used to set only the origin and end points. It does not change the PID and other parameter values that already have been set. This is usually used when the origin and end points of the already calibrated positioner have changed slightly.
Smart Positioner YT-3100 Product Manual Travel Zero (TVL ZERO) and Travel end (TVL ENd) 9.6.4 This is a manual adjustment of the zero point or endpoint of the valve after auto calibration. Once you enter the TRAVEL ZERO (or TRAVE END) setting, press the UP/DOWN button to change the zero point (or endpoint) of the valve, and then press the ENTER button to save it.
Smart Positioner YT-3100 Product Manual Manual Operation (MAN OPER) It is used to manually raise or lower the valve stem by operating the UP or DOWN buttons. This can be used to observe the move of valve stem without any external input signals. When engaged, the current input signal to the positioner has no effect on the positioner.
Smart Positioner YT-3100 Product Manual Manual Operation by MV (MAN MV) 9.7.2 The input to I/P converter is incremented or decremented by the UP and DOWN buttons based on the currently entered I/P input value, which moves the stem of the valve up and down. Once out of the menu by <ESC>, the positioner is controlled again by an input signal.
Smart Positioner YT-3100 Product Manual Control Parameters (CTL PARM) Followings are the values changeable at the Control Parameters Mode. 1) Dead Band (dEAdbANd) 2) Forward P parameter (KP UP) and reverse P parameter (KP dN) 3) Forward Integral time parameter (TI UP) and reverse Integral time parameter (TI dN)
Smart Positioner YT-3100 Product Manual Forward Integral time parameter (TI UP) and reverse Integral time parameter (TI dN) 9.8.3 TI parameters are an integral value that add the error correction signal to the existing calibration signal, TI UP is applied when the valve moves in the direction of increasing the output air pressure, and TI DN is applied when the valve moves in the direction of decreasing the output air pressure.
Smart Positioner YT-3100 Product Manual Auto Dead band Mode (AUTO db) 9.8.5 This function is used to suppress a hunting for valves with high static friction. The initial value is OFF and it shall be set to 0 % to activate the auto dead band automatically. The value is changed to a proper value once this mode is activated.
