Effective June, 2001
We will only be concerned with System Config and Protection
settings here.
Select the category and press the Enter pushbutton to proceed. The
actual setting of values will be covered in Section 2.5.5.
2.5.4 Minimum Program Requirements
Default settings are provided to minimize the number of manual
programming steps for typical applications. For more complex
applications cases, the use of computer generated setting files
simplifies the setting process. The user programs through the RS-
232 front panel port by use of the PowerPort
TM
Windows

based or
PowerNet
TM
Software program. This subject is treated more
extensively later in the manual.
2.5.5 Functions Which Must be Programmed
The FP-5000 comes pre-configured with default or factory settings.
The phase and ground overcurrent functions are the only protection
functions enabled. All other protection functions are turned off and
must be set to enable their operation. The I/O comes pre-configured
as default from the factory for the most common applications. The
I/O can be changed per the requirements of the user’s application.
For now we assume that the default settings will be adequate
except for the following list of functions, which the user must
program in order to handle the specific characteristics of your
system. Since only one protection setting Group is enabled, we
need only program the one group of protection settings and the
values necessary to define the proper operating environment of the
FP-5000. Please refer to Table 2.1 Minimum List of Functions
Which MUST be Programmed for those items.
