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)

1:33 (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.
