They are TRIPS, ALARMS, and BLOCKS. a) TRIPS An 469 trip feature may be assigned to any combination of the two Auxiliary relays, R2 and R3, in addition to the R1 Trip Relay. If a Trip becomes active, the appropriate LED (indicator) on the 469 faceplate will illuminate to show which of the output relays has operated. In addition to the Trip relay(s), a trip will always operate the Block Start relay. Trip features are may be programmed as latched or unlatched. Once a relay has been operated by a latched trip, a reset must be performed to clear the trip when the condition is no longer present. If there is a lockout time, the Block Start relay will not reset until the lockout time has expired. If an unlatched trip feature becomes active, that trip will reset itself (and associated output relays) as soon as the condition that caused the trip ceases. Immediately prior to issuing a trip, the 469 takes a snapshot of motor parameters and stores them as pre-trip values which will allow for troubleshooting after the trip occurs. The cause of last trip message is updated with the current trip and the 469 display defaults to that message. All trip features are automatically logged and date and time stamped as they occur. In addition, all trips are counted and logged as statistics such that any long term trends may be identified. b) ALARMS An 469 alarm feature may be assigned to operate any combination of three output relays, R4 Alarm, R3 Auxiliary, and R2 Auxiliary. When an Alarm becomes active, the appropriate LED (indicator) on the 469 faceplate will illuminate when an output relay(s) has operated. Each alarm feature may be programmed as latched or unlatched. Once a latched alarm feature becomes active, the reset key must be pressed to reset that alarm. If the condition that has caused the alarm is still present (e.g. hot RTD) the Alarm relay(s) will not reset until the condition is no longer present. If on the other hand, an unlatched alarm feature becomes active, that alarm will reset itself (and associated output relay(s)) as soon as the condition that caused the alarm ceases. As soon as an alarm occurs, the alarms messages are updated to reflect the alarm and the 469 display defaults to that message. Since it may not be desirable to log all alarms as events, each alarm feature may be programmed to log as an event or not. If an alarm is programmed to log as an event, when it becomes active, it is automatically logged as a date and time stamped event. c) BLOCK START An 469 Block Start is a feature that prevents or inhibits the start of the motor based on some
