It would be very undesirable to start the motor at this time. In another scenario, a motor may be driving a very high inertia load. Once the supply to the motor is disconnected, the rotor may continue to turn for a long period of time as it decelerates. The motor has now become a generator and applying supply voltage out of phase may result in catastrophic failure. The Restart Block feature is strictly a timer. The 469 does not sense rotor rotation. n RESTART BLOCK n [ENTER] for more RESTART BLOCK: Off Range: On, Off RESTART BLOCK TIME: 1 s Range: 1 to 50000 s in steps of 1 ENTER ESCAPE e e MESSAGE ESCAPE NOTE GE Multilin 469 Motor Management Relay 4-51 4 SETPOINTS 4.9 S8 RTD TEMPERATURE 4 4.9S8 RTD TEMPERATURE 4.9.1 RTD TYPES PATH: SETPOINTS ?× S8 RTD TEMPERATURE ? RTD TYPES Each of the twelve RTDs may be configured as "None" or any one of four application types: "Stator", "Bearing", "Ambient", or "Other". Each of these types may in turn be any one of four different RTD types: "100 Ohm Platinum", "120 Ohm Nickel", "100 Ohm Nickel", or "10 Ohm Copper".

There are individual alarm and trip configurations for each RTD. This allows one of the RTDs to be turned off if it malfunctions. The alarm level is normally set slightly above the normal running temperature. The high alarm is usually set as a warning of a trip or to initiate an orderly shutdown before tripping occurs. The trip level is normally set at the insulation rating. Trip voting has been added for extra reliability in the event of RTD malfunction. If enabled, a second RTD must also exceed the trip temperature of the RTD being checked before a trip will be issued. If the RTD is chosen to vote with itself, the voting feature is disabled. Each RTD name may be changed if desired. n RTD #1 n [ENTER] for more RTD #1 APPLICATION: Stator Range: Stator, Bearing, Ambient, Other, None RTD #1 NAME: Range: 8 alphanumeric characters RTD #1 ALARM: Off Range: Off, Latched, Unlatched ASSIGN ALARM RELAYS: Alarm Range: Alarm, Alarm & Auxiliary2, Alarm & Aux2 & Aux3, Alarm & Auxiliary3, Auxiliary2, Aux2 & Aux3, Auxiliary3 RTD #1 ALARM TEMPERATURE: 130°C Range: 1 to 250°C in steps of 1 RTD #1 HIGH ALARM: Off Range: Off, Latched, Unlatched HIGH ALARM RELAYS: Alarm Range: Alarm, Alarm & Auxiliary2, Alarm & Aux2 & Aux3, Alarm & Auxiliary3, Auxiliary2, Aux2 & Aux3, Auxiliary3 RTD #1 HIGH ALARM TEMPERATURE: 130°C Range: 1 to 250 in steps of 1 RTD #1 ALARM EVENTS: Off Range: On, Off RTD #1 TRIP: Off Range: Off, Latched, Unlatched RTD #1 TRIP VOTING: RTD #1 Range: RTD #1 to RTD #12 ASSIGN TRIP RELAYS: Trip Range: Trip, Trip & Auxiliary2, Trip & Aux2 & Aux3, Trip & Auxiliary3 RTD #1 TRIP TEMPERATURE: 155°C Range: 1 to 250°C in steps of 1 ENTER ESCAPE e e MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Multilin 469 Motor Management Relay 4-53 4 SETPOINTS 4.9 S8 RTD TEMPERATURE 4 4.9.3 RTDS 7 TO 10 PATH: SETPOINTS ?× S8 RTD TEMPERATURE ?× RTD #7(10) RTDs 7 through 10 default to "Bearing" RTD type.
