SMAR FY301, Инструкция по эксплуатации и техническому обслуживанию

Страница: 31 / 82

Configuration
3.3
The TSO stands for "Tight Shut Off", which assure the valve is totally closed, avoiding leakage on the
valve seat. If the TSO value is 5% the valve will only start moving from the close position (for instance)
on 5% of the controller signal. The TSO D stands for "Tight Shut Off Deadband". When the value is 1%,
the valve will start to move from the close position on 6%. On 4% the valve shall close totally.
Configuration Resources
By means of the Hart
®
Configurator, the
FY301
firmware allows the following configuration features to
be accessed:

Positioner’s Identification and Manufacturing Data;

Remote movement;

Special characterization function according to a 16-point configurable curve;

Flow characterization (Linear, equal percentage and quick opening);

Monitoring of all device variables: input, setpoint, deviation and modulated output temperature;

Diagnostic (Preventive maintenance);

Positioner diagnostic and fail determination;

PID Controller Configuration;

Device Configuration;

Device Maintenance.
The operations between the configurator and the positioner, do not interrupt the valve positioning, and
do not disturb the positioner operation. The configurator can be connected to the same pair of wires as
the 4-20 mA signal, up to 2 kilometers away from the positioner.
Identification and Manufacturing Data
The following information about the
FY301
manufacturing and identification data is available:

TAG
- 8-character alphanumeric field for identification of the positioner.

DESCRIPTION
-
16-character alphanumeric field for additional identification of the positioner. May
be used to identify service or location.

MESSAGE
- 32-character alphanumeric field for any other information, such as the name of the
person who made the last calibration, some special care to be taken, or if a ladder is needed for
physical access to the positioner.

DATE
- The date may be used to identify a relevant date, such as the last calibration, the next
calibration or the installation. The date is presented in the American standard e.g. (Example: Oct
30, 2003) is automatically assumed after the choice of these items.

UNIQUE ID
- Used to identify the device and in construction of Hart
®
long address.

DEVICE INFORMATION
- This button allows to read device identification and data recorded in the
factory.
NOTE
These information items cannot be modified. They are read directly from the circuit memory.
Monitoring
This function allows remote monitoring up to 4 different of positioner variables at the same time. The
time to start the reading is around 5 seconds. The values are always updated. Altogether, 20 items
could be monitored. These items are: valve actual position in percentage, input in percentage of
adjusted current range (before the limits and flow linearization), input current in mA or %, device
temperature in Celsius and in Fahrenheit degrees, etc..
