8.3 Setting Parameters using
DTM
When confi gure the parameters using FieldMate,
use the DTM (Device Type Manager) refering to the
following table.
DTM Name Device Type

DYF V4.1 0 x 37 4
8.4 Interconnection between
digitalYEWFLO and HART
Confi guration Tool
The HART Confi guration Tool can interface with
the digitalYEWFLO from the control room, the
digitalYEWFLO site, or any other wiring termination
point in the loop, provided there is a minimum load
resistance of 250 between the connection and
the receiving instrument. To communicate, it must
be connected in parallel with the digitalYEWFLO,
and the connections must be non-polarized. Figure
8.2 illustrates the wiring connections for a direct
interface at the digitalYEWFLO site. The HART
Confi guration Tool can be used for remote access
from any terminal strip as well.

WARNING
Be sure to set parameters as “Protect” on the
write protect function after fi nish of parameter
setting work. Refer to Section 8.9 “Software
Write Protect” how to use the write protect
function in detail.
IMPORTANT
If the power of fl owmeter is turned off within 30
seconds after parameters have been set, these
settings will be canceled. Accordingly, please
keep the power on for at least 30 seconds after
setting parameters.
NOTE
Before updating any setting, remember to
always check the data content you want to
change as described in Section 6.4 “Parameters
Description”.
