Once transition is initiated, the 469 assumes the motor is still running for at least 2 seconds. This prevents the 469 from recognizing an additional start if motor current goes to zero during an open transition.

The 469 has nine digital inputs. Five of the 469 digital inputs have been pre-assigned as switches having a specific function. Four of the five pre-assigned digital inputs are always functional and do not have any setpoint messages associated with them. The fifth, Starter Status, may be configured for either an 'a' or 'b' auxiliary contact. The remaining four digital inputs are assignable; that is to say, the function that the input is used for may be chosen from one of a number of different functions. Some of those functions are very specific, others may be programmed to adapt to the user requirements. If the Two-Speed Motor feature is enabled, ASSIGNABLE INPUT 4 will be dedicated as the Two-Speed Motor Monitor. 4.4.2 ACCESS SWITCH Terminals C1 and C2 must be shorted to allow changing of any setpoint values. This safeguard is in addition to the setpoint passcode feature, which functions independently (see Section 4.2.1: PASSCODE on page 4–4). 4.4.3 TEST SWITCH Once the 469 is in service, it may be tested from time to time as part of a regular maintenance schedule. The relay will have accumulated statistical information relating historically to starter and motor operation. This information includes: last trip data, demand data (if the metering features are in use), MWh and Mvarh metering, RTD maximums, the event record, analog input minimums and maximums, number of motor trips, number of trips by type, total motor running hours, learned parameters, number of starter operations, number of motor starts, number of emergency restarts, and the digital counter. Shorting the 469 Test input (terminals C3 and C4) prevents all of this data from being corrupted or updated when the relay is under test. The In Service LED will flash while the test terminals are shorted. 4.4.4 EMERGENCY RESTART Shorting terminals D17 and D23 discharges the thermal capacity used to zero, sets any Starts/Hour Block lockout to zero, sets any Time Between Starts Block lockout to zero, and reset all Trips and Alarms so that a hot motor may be restarted. However, a Restart Block lockout will remain active (it may be used as a backspin timer) and any trip condition that remains
