CUTOFF
Factory setting:
AUTO CUT MIN value: 1%
AUTO CUT MAX value: 99%
MANU CUT MIN value: 2%
MANU CUT MAX value: 98%
When the percentage of set-point value is in the enabled range of CUTOFF, the valve actuator will be fully pressurized or
evacuated. The valve is fully closed when the percentage of set-point value is less than or equal to MIN setting parameter and is
fully open when the percentage of set-point value is greater than or equal to MAX setting parameter.
This function has the options of AUTO CUT function in the automatic mode and MANU CUT function in the manual mode.
Parameter MIN range: 0-25%, Parameter MAX range: 75-100%. When this function is enabled, the text “CUT OFF” is displayed
on the operating interface.
In the automatic mode, when the MIN data is 0%, CUTOFF for closing the valve is inactive; when the MAX data is 100%,
CUTOFF for opening the valve is inactive.
When this function is enabled, due to the actuator internal characteristics, the valve position will have some deviations after the
valve is fully closed or fully opened. As a result, the position value may be smaller than 0% when the valve is fully closed or
bigger than 100% when the valve is fully opened.
Use the arrow keys to scroll to CUTOFF and press the ENT key to open the selection menu. Use the arrow keys to navigate to
a specific function. Follow the same process to open AUTO CUT and MANU CUT. Press the EXIT key to return to the main
menu.
