Document No. 5002866 Rev. C (DRAFT) 28 April 2003 indicators and the audible alarm have been verified, the display shows GETS GS LOCOTROL RCL, and the OCU is now ready for linking to the Setup Control Unit (SCU). If the locomotive is not set up properly for RCL operation (i.e., Air brake cutout cock not cut in, Locomotive trucks cutout, automatic brake handle not in release, etc.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 Figure 3.4.1-1 Linking A secondary OCU can be linked to the LCU for use during Pitch and Catch operations. Linking the secondary OCU is accomplished in the same manner as the Primary OCU except the Primary OCU must acknowledge and authorize the secondary OCU linking. The process for linking the secondary OCU is outlined below: 1.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 OCU will display Consist Recovering and if the test passes, BP will recover and the OCU will display Consist Ready. Upon successful completion of the Link operation, recovery of the Set Up Emergency, and verifying the emergency valves, the Locomotive Control Unit (LCU) transitions into the Ready State. The Ry State allows an OCU operator to control the locomotive’s speed and brakes. The SCU display Remote Mode on the display. 3.4.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 3.4.4 System Operating States The following sections identify and describe the main operating States of the RCL system and the criteria used to transition between states. 3.4.4.1 Initialization (Power Up) State Upon power up the LCU performs a power up self-test and checks the status of the locomotive, brake, and yard containment. If the self-test passes, the LCU system transitions to the Setup State.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 • Headlights • Horn • Sand The system monitors the yard containment to ensure that the system is operating safely within the proper boundaries. The system also monitors all critical parameters and subsystems to ensure no fault conditions are present. If fault conditions are detected, the system transitions to either the Park State or the Safe State, depending on the severity of the fault.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 • The Fault has been cleared • A 60 second Emergency Brake timer has elapsed. (The OCU display shows a 60 seconds count down timer when the IBS is placed in the Emergency position to indicate the time remaining). • The operator acknowledges the fault by moving the SS actuator to the STOP position and the IBS actuator to the EMERGENCY position as prompted by the OCU.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 To release from charge pull back of ABS momentarily. Note: i) Locomotive is not allowed to move while in charge. ii)If MR is less than 110 psi the RCL system will “dry charge” the locomotive by setting throttle to Notch 4 (Direction is Neutral). 3.5.1.3 Independent Brakes The locomotive independent brake functions are controlled manually by the operator via the Operator control Unit (OCU) or automatically (during speed control operation) by the LCU.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 a) Rotate the IBS actuator to the EMER position on either the Primary or Secondary OCU. This causes an emergency brake command to be sent to the LCU on the locomotive which puts the train in to emergency. b) Cause a brake pipe emergency at the locomotive cabstand by moving the automatic brake handle to emergency or opening the conductor’s emergency valve.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 5. Low Brake Pipe – If the brake pipe pressure drops below 45 psi, the locomotive will be commanded to a Safe State. If the direction is neutral and the brake cylinder pressure is greater than 25 psi this interlock will be disabled. 6. Brake Pipe Rise – The LCU system continually monitors the brake pipe pressure during all automatic brake applications.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 3.5.3.3 Speed Control The RCL system provides a speed control system for controlling traction and moving the locomotive and train. Provisions are made within the speed control algorithms for operation at Hump yards and Flat yards. 3.5.3.3.1 Throttle vs Excitation Speed Mode Before linking the OCU, the SCU inside the locomotive can be set to excitation or throttle mode. On the SCU press MENU, scroll down to the Speed Control option.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 The LCU receives commands from the OCU and releases the locomotive brakes, sets the commanded direction, and enters the Speed Control mode. The LCU rings the Bell for 3 seconds and then the LCU increases the throttle and generator excitation until the train starts moving. The throttle and excitation are then continually adjusted, as required, to maintain the commanded speed. The operator may increase or decrease the set speed using the SS on the OCU.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 3.5.3.5 Horn / Bell Control The RCL system provides control of the locomotive bell and horn. The Bell and Horn can manually be controlled by using the OCU. In addition, the LCU automatically activates the Bell when commanded by AEI Tags. When the locomotive enters Speed mode the LCU automatically activates the locomotive Bell for 3 seconds before the locomotive is moved.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 6. During Speed Control operation, only valid throttle steps are allowed. Invalid throttle steps detected by the LCU puts the locomotive in the Park State. 7. Loss of communications between the LCU and the SCU causes the LCU to put the locomotive in the Park State. 3.6 Special Operating Features The RCL system provides special features to aid and enhance operational effectiveness. 3.6.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 To put the system into Sleep mode, power down the primary and/or secondary OCU and follow the directions on the OCU for entering Sleep mode. The OCU will confirm Sleep mode before shutting down and the OCU #1 (#2) linked LED will flash on the SCU. To go back to RCL mode, power on the OCU using the PWR button within 90 minutes from going into Sleep mode.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 yard containment tags, which will cause the LCU to bring the locomotive to a stop (Park State) and applying a Full service independent and automatic brake application. 3.6.4.2 Speed Restrictions Speed Restriction tags can be used to restrict the speed of the locomotive through sections of track. This allows the yard personnel to set speed restrictions. The LCU will restrict the OCU commanded speed when these tags are read (if they are more restrictive).
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 Figure 3.6.4.3-1 Pullback Control 3.6.4.4 Bell and Horn Bell and Horn tags can be used to automatically sound that the horn or bell. These tags are placed at crossings in the yard, or in places where they are normally sounded. 3.6.5 GPS The Global Positioning System (GPS) containment system provides a backup to the AEI tag system.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 3.6.6 Vigilance The OCU is equipped with a Vigilance system. Whenever any speed selector on the primary OCU is out of STOP, a 60 second timer is started. If any OCU control has not been changed, or the vigilance reset function has not been activated for 60 seconds, the OCU sends a PARK command to the LCU, idles the locomotive and applies brakes. If a control vigilance reset has not been activated for 50 seconds, the OCU emits an audible alarm notifying.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 timer and preempts the normal tilt/operator down process. The Tilt O/R indicator flashes and the display indicates Tilt Override Active, Timer Set to 60 Sec. If the OCU is in the tilted state when the tile by-pass timer reaches 50 seconds, the OCU will output the audible operator alert that the tilt by-pass timer is about to expire and display Tilt O/R Expiring, Press Tilt O/R Again.
Document No. 5002866 Rev. C (DRAFT) 28 April 2003 display. The operator receives notification via the OCU display when the battery charge calls to 60 minutes, 45 minutes, 30 minutes, 15 minutes, 10 minutes and 5 minutes. 3.7 Event Recorder The RCL system contains a Event Recorder System. These include the recording of event data, transferring of data to the display unit, the previewing of data and the printing of data. Event Recorder is covered under the service manual.
