Technical Reference Manual, General
In addition to protection, measurement, control and condition monitoring functions,
the feeder terminals are provided with a large amount of PLC functions allowing
several automation and sequence logic functions needed for substation automation
to be integrated into one unit. The data communication properties include SPA bus

communication, LON
higher-level equipment. Further, LON communication, together with PLC
functions, minimizes the need for hardwiring between the units.

If the environmental conditions differ from those specified in section "Technical
data", as to temperature and humidity, or if the atmosphere around the feeder
terminal contains chemically active gases or dust, the terminal should be visually
inspected in association with the secondary testing. The visual inspection should
focus on:
• Signs of mechanical damage to the feeder terminal case and terminals
• Dust on the feeder terminal cover or case
• Signs of corrosion on terminals, on the case or inside the feeder terminal
For information about the maintenance of feeder terminals, refer to section
"Service" on page 87.
Feeder terminals are measuring instruments and should be handled with
!
care and protected against moisture and mechanical stress, especially
during transport.

The REF 54_ feeder terminals are adapted to specific applications by using the
Relay Configuration Tool included in the CAP 505 tools. This tool is used for
configuring the basic terminal, protection and logic function blocks, control and
measurement functions, timers and other functional elements included in the logic
functions category (refer to section "Feeder terminal configuration" on page 23).
The MIMIC picture, alarm texts and LED indicators are configured with the Relay
Mimic Editor (refer to section "MIMIC configuration" on page 24).
The configuration of LON network is described in section "LON network
configuration" on page 26. If the application includes no horizontal communication,
network variables are not needed and the section about LON network configuration
is thus not relevant.
The customer can configure the REF 54_ feeder terminal according to own
functional requirements and preferences or utilize the pre-engineered configuration
solutions.
For more detailed information about the configuration, refer to the Configuration
Guideline and the tool-specific manuals (refer to section "References" on page 96).
