9.7 Use of Multiple Setting Groups
The FP-6000 contains multiple setting groups for adapting to
different operating situations. Selection of the active setting
group can be either automatic or manual. Automatic setting
group selection can be initiated by a contact input or via
communications. Manual setting group selection at the front
panel is provided for applications where different settings are
required based on maintenance needs or seasonal power
requirements. A system configuration setting provides selection
of the control mechanism for selecting the active setting group.
The setting for Control of Multiple Setpoint Groups has four
options: Contact Input, Comm, Local and Local+Comm. The
reason for providing multiple setpoint groups is to permit a quick
change of settings and to minimize the risk of changing settings.
Changing the active setpoint group is a sub-menu option of the
Status/Control mode on the user interface if the Multiple Setpoint
Group Control is set to Local. Access is not limited by the security
door or password protection, as switching between the four logic
schemes is considered part of normal operation. The active
setpoint group will also be displayed using the Status/Control
mode on the user interface.
•
If the Multiple Setpoint Group Control is set to Contact Input,
the contact inputs are defined in the Contact Input setting
section. One or two contact inputs can control the setpoint
group selection. If only one is used, the input selects between
group 1 (Cin = Sel Set1 = 0) and group 2 (Cin = Sel Set1 = 1). If
two contact inputs are used, the combination of the two
contact inputs provides selection of group 1 (00), group 2 (01),
group 3 (10), or group 4 (11).
•
If the Multiple Setpoint Group Control is set to Local, the active
setpoint group is selected using a sub-menu option of the
Status/Control mode PB on the user interface.
•
If the Multiple Setpoint Group Control is set to Remote, the
active setpoint group is selected using a PowerNet slave action
command (3 D 0).
•
If the Multiple Setpoint Group Control is set to Local+Remote,
the active setpoint group is selected using either a sub-menu
option of the Status/Control PB or the PowerNet slave action
command (3 D 0). The active setpoint group is the group that
was selected last.
Logic gate outputs can be enabled for one setting group or for all
setting groups.
9.8 Default Settings
If no programming steps are taken, the inputs and outputs will
have default settings that are likely to satisfy the majority of user
applications with no setting changes required. Attempts to
program the inputs, outputs, or any logic will be prevented until
the user changes the System Configuration settings for I/O Config
or Prog Logic from Default to Custom. Attempting to access
Contact input CFG or Output Config within the Set or
Programming mode when I/O Config is Default will result in a few
seconds of the display.
Attempting to access Programmable Logic settings when Prog
Logic is set to Default will result in the same message.
9.9 Programmable LED Logic Gates
The FP-6000 is equipped with 15 LEDs. Among those, 7 are
dedicated to Relay Operational, Breaker Closed, Breaker Open,
Phase Trip, Ground Trip, Alarm, and Pickup. The other 8 LEDs are
made programmable through the use of the programmable logic
gate mechanisms. The programmable LEDs are set the same
way as other programmable logic gates. The only difference is
that the programmable LEDs have one extra input option
category to choose, which is the Display Mode. The display
mode includes Monitor, View, Log, Status, Set, and Test. On the
FP-4000/FP-5000 relay, these display modes have their own LED
indicator. Thus, it is obvious to user which display mode is being
used by the device. In the FP-6000, these display mode indicators
are made as the programmable LEDs, so the user has to
remember which display mode you are in. Without the
indicators, the user can easily distinguish one mode from
another. Adding the display mode input category to the
programmable LED logic gates enables the user to program the
FP-6000 display just like the FP-5000 from the display point of
view. Note that there is an exception to the programmable LEDs
7 and 8. The Test mode is OR-ed with the programmable LED
7 logic gate output to the LED 7 and the other Trip is OR-ed with
the programmable LED 8 logic gate output to the LED 8.
