GE 869 - Contactor Control

CHAPTER 4: SETPOINTS CONTROL
869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–359
Contactor Control
The selection for the Breaker or Contactor is available under the Motor Setup menu. The
settings and logic for the Contactor Control described below only apply when the
Contactor is selected, and the Control mode is set to Remote (Local Mode set to “Off”, or the
selected LOCAL MODE operand de-asserted).
The selection for the Switching Device for either the Breaker or Contactor is available in the
Motor Setup menu.
NOTE
NOTE:
The breaker “Remote Block Open”, “Remote Block Close”, “Bypass Rem Blk Open” and
“Bypass Rem Blk Close” flags are inhibited, when the setpoint Select Before Operate
residing under the Local Control Mode menu is set to Disabled. The breaker remote open
and close commands are still operational.

Path: Setpoints > Control > Contactor Control > Cnct1 Control
REMOTE OPEN
Range: Off, On, Any FlexLogic operand
Default: Off
This setpoint is active, when the Local Mode is inactive. The setting specifies the input
that when asserted, initiates a “STOP” command. When the selected input is asserted,
the output relay #1 is energized and stays energized until the input drops off, the
breaker (or contactor) opens, and the selected Seal-in time expires. This setpoint
provides flexibility to operate output relay #1 by selecting an operand from the list of
FlexLogic operands, contact inputs, virtual inputs, or remote inputs. For example, the
operand “Phase OV 1 OP” can be selected to activate output relay #1 according to the
operate conditions configured under the Phase OV 1 menu.
REMOTE CLOSE
Range: Off, On, Any FlexLogic operand
Default: Off
This setpoint is active, when the Local Mode is inactive. This setting specifies the input
that when asserted, initiates a START command. This setpoint provides flexibility to
operate the designated output relay by selecting an operand from the list of FlexLogic
operands, contact inputs, virtual inputs, or remote inputs.
FAST PATH:
The START command operates Output relay 2 if Setpoint > System > Contactor > Contactor
1 > Close Relay Select is set to “Relay 2”.
