9.1 Contact Inputs
The FP-5000 is equipped with eight optically isolated inputs that
may be configured as inputs to pre-defined FP-5000 functions or for
custom logic applications. The contact inputs are either ON
(external contact closed) or OFF (external contact open). They are
“debounced” for one power line cycle to prevent false operation
from transient signals. Because of the debouncing, signals are not
processed until the input remains stable for one cycle.
The contact inputs are designed to be activated by connecting the
“C In Source” voltage on terminal block TB2 to the desired inputs
through a dry contact, typically an external switch, pushbutton, or
relay contact. See Section 6.2.5.
The contact inputs can be configured as circuit breaker logic inputs,
Remote Reset, Setting Group Selection, Datalogger Trigger,
Demand Sync, or for user-defined logic functions. The contact
inputs can also be programmed as an input to any logic gate. The
logic gates provide blocking of the protective functions, operation of
the output relays, and provisions for custom logic. The Contact
Input setting options are shown below. With the exception of the
user-defined option, each function can be programmed to only one
contact input.
• 52a
• Remote Reset
• 52b
• Datalogger Trigger
• Breaker Failure Initiate (BFI)
• Demand Sync
• Breaker Trouble
• Setting Group 1
• Remote Open
• Setting Group 2
• Remote Close
• User Defined
The FP-5000 is shipped from the factory with default settings for the
Contact Inputs. It is necessary to change the System Configuration
setting (activated by the “Set” pushbutton) “I/O Config” from
“Default” to “Custom” to change the programmed function of the
inputs. The eight inputs are pre-defined with the following default
functions when the input configuration is set to default.
Cin1
52a (Open/Trip) Circuit Breaker Feedback
Cin2
52b (Close) Circuit Breaker Feedback
Cin3
BFI, External Breaker Failure Initiation
Cin4
Breaker Trouble
Cin5
Remote Breaker Open (If Enabled in Settings)
Cin6
Remote Breaker Close (If Enabled in Settings)
Cin7
Remote FP-5000 Reset
Cin8

9.2 Output Relays
The FP-5000 is equipped with seven electromechanical output
relays. The relays include five Form A output relays (Trip1, Trip2,
Rly3, Rly4, Rly5), one Form C Alarm output relay, and a Form C
Relay Healthy Alarm relay. The functionality of the Relay Healthy
alarm is fixed. The functionality of the remaining six relays is
programmed via the “Output Config” setting sub-menu (activated by
the “Set” pushbutton). A 4-input logic gate is associated with each
of these six outputs. Each output of the logic gate can be configured
as an AND, OR, NAND, or NOR gate. The relays are energized
based on the output logic gate programming and de-energized
based on the dropout setting.
Output relay operation may be programmed as Latched, Unlatched,
or Off Delay. The output relay is energized when any of the features
programmed to the Output Logic Gate operate. A description of the
dropout for each mode of operation follows:
Unlatched
When configured for Unlatched operation, the
state of the output relay directly follows the
output state of the associated Output Logic
Gate. The output relay remains in the energized
state until all features programmed to operate
the relay return to the non-operated state.
Off Delay
When configured for Off Delay operation,
the output relay remains energized for an
additional Off Delay time after the Logic Gate
output clears. The output relay remains
energized until all features programmed to
operate the relay return to the non-operated
state and the number of cycles specified in
the Off Delay setpoint has expired. The
off-delay timer is started when all features
programmed to operate the relay return to the
non-operated state.
Latched
With the dropout set to Latched, a reset signal
is required to de-energize the output relay. The
Trip1, Trip2, and Alarm output relays are de-
energized by a reset from the front panel
Reset Trip, the Remote Reset contact input, or
a communication Remote Reset command. The
six programmable relays may be de-energized
by a reset from the front panel Reset Relay
menu or a communication Deactivate Relay
command. This mode is used to provide a
“lockout” function or for operations that must
be acknowledged.
The FP-5000 provides optional Trip Coil Supervision of the Trip1
output relay and Close Coil Supervision of the Trip2 output relay.
The coil monitoring functions are enabled in the “Output Config”
setting menu (activated by the “Set” pushbutton) for the Trip1 and
Trip2 relays.
The FP-5000 is shipped from the factory with default settings for the
Outputs. It will be necessary to change the System Configuration
setting “I/O Config” from “Default” to “Custom” to change the pro-
grammed function of the outputs. See Default settings in Table 9.1.
