Note: Due to the hardware configuration of the 269 drawout relay this code cannot be changed
on any drawout models without corresponding hardware change.
WARNING: In locations where system voltage disturbances cause voltage levels to dip below the
range specified in specifications (1.5), any relay contact programmed failsafe may change state.
Therefore, in any application where the "process" is more critical than the motor, it is recom-
mended that the trip relay contacts be programmed non-failsafe. In this case, it is also recom-
mended that the AUX2 contacts be monitored for relay failure. If, however, the motor is more
critical than the "process" then the trip contacts should be programmed failsafe. See
Figure 3.2 and Figure 3.3

SPARE INPUT TO READ
SPARE INPUT TO READ
52B CONTACT? XXX
52B CONTACT? XXX
This setpoint is designed to read the 52B contact of a breaker or equivalent normally closed auxiliary
contact of a contactor to determine a motor "stop" condition.
For proper operation of the 269, it is required that a 52B contact be wired to terminals 44 and 45 and this
setpoint programmed to “YES”. Only if the spare input terminals are to be used for trip or alarm pur-
poses (see next two setpoints), should this setpoint be programmed to “NO”.
Programming this setpoint to “NO” results in the 269 detecting a motor stop condition when current
drops below 5% of CT. This may result in nuisance lockouts being initiated by the 269 if the motor (syn-
chronous or induction) is running unloaded or idling, and if the starts/hour, time between starts or back-
spin timer are programmed.
YES - Enables the spare input to read the 52B contact.
NO - Disables the spare input from reading a 52B contact.
Factory Value = NO
