5.3 SYSTEM SETUP 5 SETTINGS
Assign a user-defined name (up to 6 characters) to the breaker. This name will be used in flash messages related to
Breaker No. 1.
BREAKER 1 MODE:
Selects "3-pole" mode, where all breaker poles are operated simultaneously, or "1-pole" mode where all breaker poles are
operated either independently or simultaneously.
BREAKER 1 OPEN:
Selects an operand that creates a programmable signal to operate an output relay to open Breaker No. 1.
BREAKER 1 CLOSE:
Selects an operand that creates a programmable signal to operate an output relay to close Breaker No. 1.
BREAKER 1 ΦA/3-POLE:
Selects an operand, usually a contact input connected to a breaker auxiliary position tracking mechanism. This input can be
either a 52/a or 52/b contact, or a combination the 52/a and 52/b contacts, that must be programmed to create a logic 0
when the breaker is open. If is selected as "3-Pole", this setting selects a single input as the operand used
BREAKER 1 MODE
to track the breaker open or closed position. If the mode is selected as "1-Pole", the input mentioned above is used to track
phase A and settings Φ and Φ select operands to track phases B and C, respectively.
BREAKER 1 B BREAKER 1 C
BREAKER 1 ΦB:
If the mode is selected as 3-pole, this setting has no function. If the mode is selected as 1-pole, this input is used to track
phase B as above for phase A.
BREAKER 1 ΦC:
If the mode is selected as 3-pole, this setting has no function. If the mode is selected as 1-pole, this input is used to track
5
phase C as above for phase A.
BREAKER 1 EXT ALARM:
Selects an operand, usually an external contact input, connected to a breaker alarm reporting contact.
BREAKER 1 ALARM DELAY:
Sets the delay interval during which a disagreement of status among the three pole position tracking operands will not
declare a pole disagreement, to allow for non-simultaneous operation of the poles.
BREAKER 1 OUT OF SV:
Selects an operand indicating that Breaker No. 1 is out-of-service.
MANUAL CLOSE RECAL1 TIME:
Sets the interval required to maintain setting changes in effect after an operator has initiated a manual close command to
operate a circuit breaker.
UCA SBO TIMEOUT:
The Select-Before-Operate timer specifies an interval from the receipt of the Breaker Control Select signal (pushbutton
USER 1 on the relay faceplate) until the automatic de-selection of the breaker, so that the breaker does not remain selected
indefinitely. This setting is active only if is "Enabled".
