GE MULTILIN 269 MOTOR MANAGEMENT RELAY Series Instruction Manual page 131

Active - Refers to the state of an output relay. An
output relay will become active (activate) when any of
the functions assigned to that relay indicate a trip/alarm
condition.
Inactive - Refers to the state of an output relay. An
output relay will be inactive whenever none of the
conditions assigned to that relay indicate trip/alarm
conditions.
Latched - Refers to the configuration of an output
relay. Latched relays must be manually reset after
activation. This can be done by using the Reset key or
the External Reset terminals. Trip and Aux. 2 relays
are always latched.
Unlatched - Refers to the configuration of an output
relay. An unlatched relay will be automatically reset
after the conditions causing its activation are removed.
Fail-safe (FS) - Refers to the configuration of an output
relay. When a fail-safe relay is in the no trip/no alarm
(inactive) state its coil will be energized (ie. have a
voltage across it). Thus when control power is
removed from the 269 all fail-safe output relays will go
to the active state. Aux. 2 relay is always fail-safe.
Non-fail-safe (NFS) - Refers to the configuration of an
output relay. When a non-fail-safe relay is in the no
trip/no alarm state its coil will be de-energized (ie. have
no voltage across it). Thus when control power is
removed from the 269 relay all non-fail-safe output
relays will go to the inactive state.
Tripped - Refers to the state of the motor controller,
starter, or system circuit breaker. When one of these
devices is tripped the power to the motor will be
removed. Normally the Trip relay of the 269 is used to
control this operation.
Mode - The large amount of information that can be
viewed on the 269 relay display is divided into four
modes: ACTUAL VALUES, SETPOINTS, HELP, and
TRIP/ALARM. The relay can be put into any one of
these modes for viewing specific information.
ACTUAL VALUES and SETPOINTS modes each
contain many pages of data while all four modes
contain many lines.
Page - The ACTUAL VALUES and SETPOINTS modes
are divided into a number of pages containing different
sets of information. Each page contains many lines,
only one of which can be viewed on the display at any
one time.
Line - Each relay display mode is divided into a
number of lines of data. Each line consists of 2 rows X
24 characters. One line will always be visible on the
269 relay display.
Flash Message - Flash messages are one line
messages that appear on the display in response to
certain key closures or timer indications.
messages stay on the display for 2 seconds.
Thermal Memory - This is an internal 269 relay
register which is used to thermally model the motor
being protected. When this register reaches a value of
100% the entire thermal capacity of the motor has been
used and an OVERLOAD TRIP is initiated.
