6.8.4
Tight Shut Open (TSHUT OP)
If the current input signal is higher than the specified TSHUT UP (Tight shut open) value,
the regulator set pressure will be input to the actuator as it is and the valve will be fully
open with the larger actuator force.
6.8.5
Tight Shut Close (TSHUT CL)
When the current input signal falls below the specified TSHUT CL (tight shut close) value,
the regulator set pressure is input to the actuator as it is, and the valve is tightly closed
by a larger actuator force to prevent leakage of the valve.
6.8.6
Custom Zero Setting Mode (CST ZERO)
CST ZERO is the value of the analog input signal corresponding to the start point of set
value for Split Range Control. It is the value of analog input signal (4 ~ 20mA, 0 ~ 20mA,
0 ~ 5V, 0 ~ 10V) which can be set by the user. For example, if the analog input signal is
selected (4 to 20mA) and CST ZERO is set to 50% CST END at 100%, the valve opening
will be 0 to 100% when the input signal is in the range of 12 to 20mA.
The deviation of the current between the zero point and the end point should be at
least 25%.
