Alarm Relay Contacts; Auxiliary Relay #1 Contacts - GE 269Plus Instruction Manual

ALARM RELAY CONTACTS

These contacts are available as normally open (NO), normally closed (NC), with the same ratings as the Trip
relay but can only be programmed to activate when alarm setpoint levels are reached (on a drawout version of
the 269Plus, only one set of alarm contacts is available and the user must specify normally open or normally
closed and failsafe or non-failsafe when ordering). Thus these contacts may be used to signal a low level fault
condition prior to motor shut-down.

Conditions which can be programmed to activate the relay are alarm levels for the following functions: immedi-
ate overload; mechanical jam; unbalance; undercurrent; ground fault; stator RTD overtemperature; high stator
RTD overtemperature; RTD overtemperature; high RTD overtemperature; broken RTD; low temperature or
shorted RTD; spare input alarm; and self-test alarm (see Section a): STARTS/HOUR TIMER on page 3–15 for
factory preset configurations). The relay can be configured as latched or unlatched and fail-safe or non-fail-
safe.
Connections to the Alarm relay contacts are made via a terminal block which uses #6 screws.
The rear of the 269Plus relay shows output relay contacts in their power down state. Figures 2–7:

PHASE CTs), and 2–10: RELAY WIRING DIAGRAM (DC CONTROL POWER) show output relay

contacts with power applied, no trips or alarms, and Factory Configurations in effect (i.e. TRIP: fail-
safe, ALARM: non-fail-safe, AUX.1: non-fail-safe, AUX.2: fail-safe). See Figure 2–8: OUTPUT
RELAY CONTACT STATES on page 2–9 for a list of all possible contact states.
Auxiliary relay #1 is provided to give an extra set of NO/NC contacts which operate independently of the other
relay contacts (on a Drawout version of the 269Plus, only one set of Aux.1 contacts is available and the user
must specify normally open or normally closed and failsafe or non-failsafe when ordering). This auxiliary relay
has the same ratings as the Trip relay.
Auxiliary relay #1 can be configured as latched or unlatched and fail-safe or non-fail-safe. The conditions that
will activate this relay can be any trip or alarm indications (see Section 3.4: ACTUAL VALUES MODE on page
3–7 for factory preset configurations).
These contacts may be used for alarm purposes or to trip devices other than the motor contactor. For example,
the ground fault and short circuit functions may be directed to Auxiliary relay #1 to trip the main circuit breaker
rather than the motor starter.
Connections to the relay contacts are made via a terminal block which uses #6 screws.
