Instructions for the FP-6000 Protective Relay
“Enter” Pushbutton
The “Enter” pushbutton allows
the user to view the display
menus, which are chosen by the
up/down arrows. It also is used
in the programming mode to
change setting values and save
the settings. Once a setting is
chosen by the up/down arrows,
the “Enter” pushbutton is used
to enter that setting. If the
“Enter” pushbutton is not
pushed when changing a
setting, that setting will not be
changed.
4.4 RS-232 Communications Port / Front Panel
Communication
The FP-6000 communications port (located on the bottom right of
the front panel) is a straight through DB9 RS-232 communica-
tions port. It’s used to view the status of the FP-6000 and to
download setpoints via Eaton’s Power Port Communications soft-
ware and a personal computer. It is also used for upgrading firm-
ware using the Flashloader program. PowerPort software can be
obtained from the Eaton Internet site, www.eaton.com/electrical.
The FP-6000 transmits communications on pin 2 and it receives
communications on pin 3, making it a Data Set or Data
Communication Equipment (DSE/DCE) under the definitions of
the RS-232 standard. The FP-6000 does not use the RS-232
hardware control lines. Although the FP-6000 operates with the
“3-wire” connection, a standard off-the-shelf serial cable will
allow communication. See Figure 9 for the DB9 cable
connections. An example of an off-the-shelf cable is the
RadioShack
®
, 26-117B, Male DB9 to Female DB9 Shielded RS-
232C Cable.
See Section 10 for a detailed description of the FP-6000
communications and the Eaton PowerPort software.

Connectors.
4.5 Battery for Trip Indication
Beneath the front panel communications port lays a receptacle
for a lithium disc-style battery. The battery is used when there’s a
control power failure to latch the FP-6000 trip state and to
operate the front panel trip LED. The FP-6000 can last 72 hours in
this state on a completely charged lithium battery. When the
FP-6000 is energized, the trip latch and LED indicators are
powered by system power, preserving the batteries capacity.
