Installation
1.5
Intrinsic Safety Barrier
When the Fieldbus is in an area requiring intrinsic safety, a barrier must be inserted on the trunk
between the power supply and the DP/PA coupler, when it is Non-Ex type.
Use of
DF47
is recommended.
Jumper Configuration
In order to work properly, the jumpers J1 and W1 located in the
FI303
main board must be correctly
configured (See Table 1.1 - Description of the Jumpers).
J1 This jumper enables the simulation mode parameter in the AO block.
W1 This jumper enables the local adjustment programming tree.
Table 1.1 - Description of the Jumpers
Power Supply
The
FI303
receives power from the bus via the signal wiring. The power supply may come from a
separate unit or from another device such as a controller or DCS.
The voltage should be between 9 to 32 Vdc for non-intrinsic safe applications.
A special requirement applies to the power supply used in an intrinsically safe bus and depends on
the type of barrier used.
Use of
PS302 is recommended as power supply.
