color) on the left of the boar as shown in the figure2.3. When there’s no insertion or insertion of two points
underside, it’s high-level warning (warning current≥21.75mA)
；
When it’s the insertion of two points upside, it’s
low-level warning (warning current≤3.7mA).
Configuration Protection Jumper Setting
G0310 MODBUS to HART Gateway provides jumper setting of device configuration protection by JP1 WrD(in
red color) as shown in the Figure 2.3. When it’s the insertion of two points upside, it’s configuration protection. At
this moment no change of device configuration is allowed. It is allowed when there’s no insertion or insertion of
two points underside.

When HART intelligent instrument is running, it will compare PV and range upper and lower limiting value
constantly. When PV exceeds the limit, instrument will output fixed current. When PV is higher than upper limit, it
output 20.8mA
；
When PV is lower than upper limit, it output 3.8mA.
2.3 Internal load resistance
Terminal 13 and 14 connects 250
Ω
Internal load resistance, which has no connection with internal circuit. User
can use Internal load resistance to replace resistance in Figure 2.2. Then HART Modem can connect on terminal 13
and 14.
2.4 Recalibration
Users can make a recalibration on G0310 Modbus to HART gateway at test room or installation site before it
was put into application. The operation process is shown as in the Figure 2.4.
