RUN LAMP (GREEN): . INDICATES NORMAL ON CONDITION. . IF OUT, A MAJOR ALARM CONDITION IS INDICATED (DISPLAYED AT REMOTE LOCATION) CAUSED BY ONE OF FOLLOWING CONDITIONS: - POWER OUTAGE, - DEFECTIVE CPM OR SWC OSCILLATING CIRCUIT, OR - SIXTEENTH FAILURE TO RESTART SYSTEM VIA WATCH- DOG TIMER. . 6PFT CARD AUTOMATICALLY SWITCHES ITS CIRCUITS TO POWER FAILURE TRANSFER MODE. ALARM LAMP (RED): @ INDICATES A MINOR ALARM CONDITION (REMOTE LOCATION) BECAUSE SOFTWARE HAS DETECTED A FAILURE IN ONE OR MORE SYSTEM AREAS. 0 FAULT LOG (CMC-801) LISTS MORE DETAILED INFORMATION ON CAUSES OF FAILURE. THblE OVERFLOW (TO) LAMP (RED): 0 INDICATES WATCH-DOG TIMER HAS DETECTED A FAILURE IN CPM CARD OR OPERATING PROGRAM. 0 SYSTEM AUTOMATICALLY ATTEMPTS RESTART AND IF SUCCESSFUL, LOGS FAULT IN FAULT LOG. 0 AFTER 16 UNSUCCESSFUL RETRIES, RUN LAMP IS TURNED OFF. TO LAMP MUST BE TURNED OFF BY COLD OR HOT RESTART, OR BY READING FAULT LOG. - RUN (GREEN) T- ALM (RED) UP-COLD RESTART CAUTION REESTABLISHES DEFAULT DATA BASE.

Remote Alarm Stat CUSTOMER PROVIDED ALARMS AT REMOTE LOCATIONS CAN INDICATE ONE OF TWO ALARM STATES: MAJOR ALARM - . SYSTEM POWER IS OFF AND SYSTEM IS IN POWER FAILURE TRANSFER MODE. MINOR ALARM - . SYSTEM HAS FAILURE IN ONE OR MORE AREAS OF OPERATION. IF BOTH ALARMS ARE ON, THE SYSTEM HAS DETECTED A SYSTEM-WIDE PROBLEM. 3.11
PROGRAMMED ALAlwl BUTTON ON BLF/lxS (OR OTHER DESIGNATED MT INSTRUMENT) lNDKATES A MINOR ALARM CONDITION. LOCATION OF PROBLEIM A D FAULT LOG LISTING CAN BE OBTAINED THROUGH USE OF PIMP OR IVET WITH CIVIC-800 AND 801. 3.12

Review Exercise - ntena ve INSTRUCTIONS: THE FOLLOWING EXERCISE CONSISTS OF MULTIPLE CHOICE, TRUE/FALSE, FILL IN THE BLANK, OR MATCHING TYPE QUESTIONS. ALL AVAILABLE RESOURCES (I.E., STUDENT WORK- BOOK, NOTES, AND GTEP MANUAL) MAY BE USED AS REFERENCES. SUBMIT EXERCISE TO IINSTRUCTOR FOR GRADING WHEN LAST QUESTION HAS BEEN COMPLETED. 1. THE TOOLS REQUIRED FOR SYSTEM DATA BASE MAINTENANCE ARE AND 2. REMOTE MAINTENANCE USING A PORTABLE MAINTENANCE PANEL REQUIRES AT BOTH THE REMOTE SITE AND AT THE OMNI SBCS SITE. 3. LIST THREE PREVENTIVE MAINTENANCE PROCEDURES RELATED TO PROPER CARE OF PCB CARDS: (4 4. THE THREE PRIMARY VISUAL INDICATORS OF SYSTEM STATUS ARE: A. CPM LED LAMPS, CABLE WARNING SYSTEM, AND MAJOR AND MINOR ALARMS AT REMOTE LOCATION. B. ALARM BUTTON ON SINGLE LINE TELEPHONE, MAJOR AND MINOR ALARMS AT REMOTE LOCATION, AND SYSTEM FAULT LOG. C. POWER ON LAMP, CPM LED LAMPS, AND POWER FAIL TRANSFER ALARM. D. CPM LED LAMPS, MAJOR AND MINOR ALARMS AT REMOTE LOCATIONS, AND ALARM BUTTON ON BLF/DSS OR EKT INSTRUMENTS. 5. HOW COULD MORE DETAILED INFORMATION BE FOUND ABOUT MINOR ALARM CONDITION OR WATCHDOG TIMER OVERFLOW? 3.14
