FY301 - Operation, Maintenance and Instructions Manual
3.4
Device Configuration
Besides the configuration services for equipment operation, the FY301 allows self-configuration.
Services from this group are related to: write protection, security position, flow characterization function,
local indication and table configuration.
WRITE PROTECTION: The configurator only shows that the writing is authorized if the W2 jumper
from main board is connected to the pins under the word DOWN.
CHARACTERIZATION FUNCTION – It changes the valve flow characteristics. For example, if
equal percentage flow characterization is applied to a valve with linear flow characteristics, it will
work as an equal percentage valve. Manufacturer documentation contains the valve inherent
characteristic. The options for applied flow characterization are:
LINEAR UNALTERED
Equal percentage 1:25
Equal percentage 1:33
Equal percentage 1:50
Quick opening 1:25 (Hyperbolic)
Quick opening 1:33 (Hyperbolic)
Quick opening 1:50 (Hyperbolic)

LOCAL INDICATIONS - The FY301 local indicator has three well-defined fields: information field
with icons informing the active status of the configuration, 4 ½ numerical digit field to value
indication and alphanumeric field with 5-digit for status information and units.
The FY301 accepts up to two local indicator configurations, showed with a 2 second pause between
each one. The parameters that can be selected to visualization are showed below:
PARAMETERS DESCRIPTION
PV % Process variable in percentage.
PV (mm) Process variable in mm.
SP % Setpoint in percentage.
SP(mm) Setpoint in mm.
TABLE CONFIGURATION - Through the Table button, a flow characterization curve with up to 16
points can be configured. This allows the construction of a special flow characterization curve, like
linear combinations and equal percentage or other characterizations.
