6 4.2 Lucy Gemini 3 Type E RTU The Lucy Gemini 3 RTU/Controller provides the control and monitoring functionality for: UKPN Spec RMUs. LPN Spec RMUs. LPN ACBs. 11kV/LV Transformer LV way. EPN/SPN Spec Lucy RMUs (in place of the Gemini 2.5). The Gemini 3 RTU/Controller utilises modern IP communications and can operate with any compliant IP communications systems, such as GPRS/3G, DSL etc, and will also operate using the PAKNET system. The main details of the Gemini 3 Type E RTU are shown in Figure 1. Figure 1 Lucy Gemini 3 Control Unit and RTU Layout The ground mount RTU can be mounted to the wall of a GRP or brick substation, or can be mounted using a floor standing frame in an open substation.

7 5 Operation 5.1 Local Controls and Indications Local controls and indications are facilitated by the use of the HMI mounted on the inside of the cabinet door, see Figure 2. Figure 2 HMI fitted to inside of RTU cabinet door 5.2 Local Operations from the Control Unit The HMI (see Figure 2) can be configured to initiate or display any function the RTU is capable of, such as: Local/remote selection. Switch or circuit-breaker open/close. Dummy circuit-breaker open/close. Check analogue values. Check alarm/indication states. Open or Close a Switch or Circuit Breaker Using the Arrow Keys select Control in the menu and press OK. Using the Arrow Keys select the desired switch and press OK. Press and hold the Act and either the Open or Close buttons for approx. 5 seconds. When the HMI display shows Operating, release the buttons. If the switchgear being operated is an RN2C there will be a delay of up to 5 seconds before the actuator starts operating, all other switchgear will operate immediately. After the delay (if any), the appropriate switch/cb should operate and the indication on the HMI will show Operation Finished and Open or Closed and the LED on the relevant DSM Module will indicate the correct switch position.

14 Appendix A Basic HMI Operations This Appendix details how to use the HMI to: Set the RTU to Local/Remote/Off Operate a Switch/Circuit Breaker Reset the FPI Pressing the Menu button at any time will take you back to the start page of the HMI. Pressing the ESC button at any time will take you back one menu level of the HMI. Always remember to set the HMI to Local before leaving site. A.1 Set the RTU to Local, Remote or Off using the HMI. To toggle between Local and Remote, press and hold the Mode button for 1 second then release. The status will only change once the button is released. To set the RTU controls to Off (this means controls cannot be operated either remotely or locally), press and hold the Mode button for approx. 5 seconds then release. To return the HMI to Local or Remote, press and hold the Mode button for approx. 1 second and release. UK Power Networks 2017 All rights reserved 14 of 15

15 A.2 Operate a Switch or Circuit Breaker Refer to the information located on the inside of the RTU door to identify which RTU switch is connected to which RMU circuit breaker/switch. Press the Menu button. Using the Arrow keys, select the desired Switch/Circuit Breaker and press OK. Using the Arrow Keys select Controls in the menu and press OK. Using the Arrow Keys select RTU SW x Open/Close (x = the desired RTU switch number) in the menu and press OK. Press and hold the Act button together with either the Open or Close buttons for approx. 5 seconds. When the HMI display shows Operating, release the buttons. If the switchgear being operated is an RN2C there will be a delay of up to 5 seconds before the actuator starts operating, all other switchgear will operate immediately. After the delay (if any), the appropriate switch/cb should operate and the indication on the HMI will show Operation Finished and Open or Closed. A.3 Reset FPI Alarm Press the Menu button. Using the Arrow keys, select the desired Switch/Circuit Breaker and press OK. Using the Arrow Keys select Controls in the menu and press OK. Using the Arrow Keys select FPI Reset in the menu and press OK. Press and hold the Act button together with either the Close button for approx. 5 seconds.
