if R2 Auxiliary is to be used for upstream trips, it cannot also be used for the control of a Reduced Voltage Start. Similarly, if R3 is to be dedicated as a relay to echo all alarm conditions to a PLC, it cannot also be used strictly to enunciate a specific alarm such as Undercurrent. In order to ensure that conflicts in relay assignment do not occur, several precautions have been taken. All trips with the exception of the Short Circuit Backup Trip default to R1 Trip output relay. All alarms default to the R4 Alarm relay. Only special control functions are defaulted to the R2 and R3 Auxiliary relays. It is recommended that these assignments be reviewed once all the setpoints have been programmed. RESET 4-6 469 Motor Management Relay GE Multilin 4.2 S1 469 SETUP 4 SETPOINTS 4 4.2S1 469 SETUP 4.2.1 PASSCODE PATH: SETPOINTS ? S1 469 SETUP ? PASSCODE A passcode access security feature is provided in addition to the setpoint access jumper. When shipped from the factory, the passcode is defaulted to 0. Passcode protection is ignored when the passcode is 0. In this case, only the setpoint access jumper is required for changing setpoints from the front panel. Passcodes are also ignored when programming setpoints via the RS485 port. However when programming setpoints using the front RS232 port and the 469PC software, a passcode is required (if enabled). To enable passcode protection on a new relay, follow the procedure below: 1. Press then until the CHANGE PASSCODE? message is displayed. 2. Select “Yes” and follow the directions to enter a new passcode 1 to 8 digits in length. 3. Once a passcode (other than “0”) is programmed, it must be entered each time setpoint access is restricted. If a nonzero passcode has been programmed and setpoint access is restricted, then the ENTER PASSCODE FOR ACCESS message appears when entering the S1 469 SETUP ? PASSCODE subgroup. 4. Enter the correct passcode. A flash message will advise if the code is incorrect and allows a retry. If the passcode is correct and the setpoint access jumper is installed, the SETPOINT ACCESS: Permitted message appears. 5. Setpoints can now be entered. Press to exit the S1 469 SETUP ? PASSCODE group and program the appropriate setpoints. If no keys are pressed for 5 minutes, programming access will no longer be allowed and the passcode must be re-entered. Removing the setpoint access jumper or setting the SETPOINT ACCESS setpoint to “Restricted” will also immediately disable setpoint access. If a new passcode is required, gain setpoint access by entering the valid passcode as described above, then press to display the CHANGE PASSCODE message and follow directions. If an invalid passcode is entered, an encrypted passcode may be viewed by pressing the key.
