Configuration
3.5
Advanced Configuration
This function affects valve advanced configurations. With advanced configuration is possible to
configure the valve type, if it is air-to-open or air-to-close, valve action, setpoint limits and split-range.
Device Maintenance
This group includes maintenance services, related to obtainment of necessary information to the device
maintenance and performance test. Some of the available services are: position adjustment and valve
performance test, general information about the actuator and the valve, operations count, password
level, code number model and performance.
Trim
There are two trim operations: Current trim and Temperature trim. Current trim allows to calibrate the
positioner input current reading and Temperature trim is the temperature reference to the positioner
temperature sensor.
There are two current trims available:
•
4 mA TRIM:
is used to adjust the input current reading correspondent to 0%.
•
20 mA TRIM:
is used to adjust the input current reading correspondent to 100%.
Setup
This function allows to calibrate the value travel automatically (Auto Setup), the points of the totally
opened or totally closed travel with higher precision (lower and higher position), to adjust the opening
and closing times and the proportional and integral actions of PI control, the state of air supply, the
magnet, the sensor Hall, setup and the piezo voltage conditions.
During the setup process, the local display, if installed, will show the setup progress, in which the
positioner takes the following steps:
10%
- It opens or closes the valve, depending on the initial value of the piezo voltage;
20%
- The positioner checks if the flat cable is connected, or if the position sensor is working properly.
In case of error, the message “HALL” will appear at local indicator;
30%
- The positioner checks whether the magnet is used linear or rotary valve;
40%
- At this point, the positioner opens or closes the valve, depending on the initial position. Case the
spool is obstructed or if the positioner has no air supply, the message “FAIL MOVE” will appear in the
local indicator.
50%
- At this moment, the positioner checks if the magnet is connected to the valve. If not, the
message “MGNT” will appear in the local indicator;
60%
- The positioner places the valve to 50
%.
The setup process could remain at this step if the Kp
value is low;
70%
- At this moment, the valve is close to 50%
.
The setup process could remain at this step, if the Kp
value is high;
80%
- The positioner adjusts its internal references to place the valve in 50%
.
The setup process could
remain at this step, if the Kp value is high;
90%
- The positioner checks if the magnet is correctly mounted (arrow in arrow). If not, the message
“MGNT” will appear in the local indicator;
100%
- End of setup;
Multidrop Configuration
ADDRESSING
-
FY301
contains a variable that define the device address in a Hart
®
network. Hart
®
addresses assume values from "0" to "15", the addresses "1" to "15" are specific addresses to
multidrop connection. When
FY301
is configured to multidrop , it means that the local indicator is
showing “MD” and the address is an value from "1" to "15".
FY301
is factory configured with address "0".
