3-52 B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUALACTIVATE RELAY CHAPTER 3: INSTALLATION3Figure 3-60: Status LEDsThe clock configuration LED status is as follows:• Flashing green — loop timing mode while receiving a valid data packet• Flashing yellow — internal mode while receiving a valid data packet• Solid red — (switch to) internal timing mode while not receiving a valid data packetThe link/activity LED status is as follows:• Flashing green — FPGA is receiving a valid data packet• Solid yellow — FPGA is receiving a "yellow bit" and remains yellow for each "yellow bit"• Solid red — FPGA is not receiving a valid packet or the packet received is invalid3.5 Activate relayThe relay is in the default “Not Programmed” state when it leaves the factory. When powered up successfully, looking atthe front panel, the "Trouble" LED is on and the "In Service" LED is off. The relay in the “Not Programmed” state blockssignaling of any output relay. These conditions remain until the relay is explicitly put into “Programmed” state.The relay can be activated on the front panel or in the EnerVista software.To activate the relay using the front panel:1. Press the MENU key until the SETTINGS header flashes momentarily and the PRODUCT SETUP message displays.2. Press the MESSAGE right arrow until the SECURITY message displays.3. Press the MESSAGE down arrow until the INSTALLATION message displays.4. Press the MESSAGE right arrow until the RELAY SETTINGS: Not Programmed message displays.RELAY SETTINGS:Not ProgrammedWhen the relay is powered up, the "Trouble LED" is on, the "In Service" LED is off, and this messagedisplays, indicating that the relay is in the "Not Programmed" state and is safeguarding (outputrelays blocked) against the installation of a relay whose settings have not been entered. Thismessage remains until the relay is explicitly put into "Programmed" state.
