CHAPTER 5: SETTINGS
469 MOTOR MANAGEMENT RELAY – INSTRUCTION MANUAL 5–25
Remote Reset
Shorting terminals D18 and D23 resets any trips or latched alarms provided that the
condition that caused the alarm or trip is no longer present. If there is a lockout time the
Block Start relay will not reset until the lockout time has expired.
5.4.2 Starter Status
PATH: SETTINGS ZV S3 DIGITAL INPUTS Z STARTER STATUS
This input is necessary for all motors. The 469 determines that a motor has stopped when
the phase current falls below the level that the relay can measure (5% of CT primary).
Monitoring an auxiliary contact from the breaker or contactor prevents the relay from
detecting additional starts when an unloaded motor is loaded, or issuing a block start after
an unloaded motor is started and running at less than 5% CT rated primary current.
If “Starter Auxiliary A”
is chosen, terminals D16 and D23 are monitored to detect the
breaker or contactor state, open signifying the breaker or contactor is open and shorted
signifying closed. The 469 will then determine that a motor has made the transition from
'running' to 'stopped' only when the measured current is less than 5% CT ratio and the 'a'
contact is open.
If “Starter Auxiliary B” is chosen, terminals D16 and D23 are monitored to detect the
breaker or contactor state, open signifying the breaker or contactor is closed and shorted
signifying open. The 469 then determines that a motor has made the transition from
'running' to 'stopped' only when the measured current is less than 5% CT ratio and the 'b'
contact is closed.
