Auxiliary Output Relays - GE MI-869 Instruction Manual

OUTPUTS
Auxiliary Output
Relays
4–98
The 869 relay is equipped with Auxiliary Output relays. The I/O cards, and a number of
auxiliary output relays are defined at the time of relay ordering. The Auxiliary Relays can be
energized directly from the menu of the protection or control feature or from their
respective menus by assigning a FlexLogic operand (trigger) under the setpoint "Aux Rly #
Operate".
Changing the state of any of the Auxiliary Relays will be inhibited if the 869 relay is in "Not
Ready" mode.

NAME
Range: Up to 13 alphanumeric characters
Default: Aux Rly #
The setpoint is used to name the auxiliary output relay by selecting up to 13
alphanumeric characters.
SEAL-IN TIME (displayed only if Type=Pulsed)
Range: 0.00 to 9.99 s in steps of 0.01 s
Default: 0.10 s
When type = Pulsed is selected, the setpoint "AUX RLY # SEAL-IN TIME" is displayed in the
menu for selection of the time interval for which the output relay will remain Energized.
The actual time, for which the output relay stays energized, starts from the time of
output first trigger, and ends when Output Seal-In Time expires. The Seal-In time applies
at the dropdown edge of the output relay. If during timing out of the Seal-In Time,
another pulse/pulses occur, the Seal-In Time will be reapplied to the last pulse, resulting
in prolonged time for which the output will stay energized before going to de-energized
mode.
BLOCK
Range: Disabled, Any operand from the list of FlexLogic operands
Default: Disabled
This setting defines a block to the Auxiliary output relay. When the selected input is
asserted, the Aux relay is blocked.
