- 1. Common Reasons For Generator Start Failure Understanding How to Properly Maintain Your Standby Power System Presented By: Jason Blacker and Jeremiah Rosenthal
- 2. BASIC COMPONENTS OF AN EMERGENCY POWER SYSTEM
- 5. COMMON REASONS FOR GENERATOR START FAILURE Controls Not in “Auto” • Start switch in “Off/Reset” position – Assure System is in “Auto” – Check weekly • “E- Stop” button pushed in – Reset E-stop – Check generator breaker
- 8. COMMON REASONS FOR GENERATOR START FAILURE Generator Output Circuit Breaker “Open” • Breaker left in “open” or “off” position – Check breaker position during weekly inspection • Breaker tripped due to fault or shunt trip – Check breaker position during weekly inspection – Continues to trip indicates fault or alarm
- 9. TYPICAL CONTROL PANEL AND CIRCUIT BREAKER
- 10. COMMON REASONS FOR GENERATOR START FAILURE Battery Failure • Age: 2-3 year life span – Failure rate increases after 3 yrs – Change before failure for uptime assurance – NFPA recommends new at 30 months • Constant charging – Check weekly electrolyte levels • Corroded terminals – Check weekly & clean terminals as needed
- 11. COMMON REASONS FOR GENERATOR START FAILURE Battery Failure • Charger turned off – Check weekly charger operation • Vibration – Check hold down bracket
- 12. BATTERY HOLD DOWN & CHARGER
- 13. COMMON REASONS FOR GENERATOR START FAILURE Low Coolant Level Alarm/ Shutdown • Low coolant level – Assure system is full to manufacturers recommendation • External or internal leak – Check for visible leaks/pooling of coolant • Block heater – Heat causes coolant to evaporate over time
- 14. COMMON REASONS FOR GENERATOR START FAILURE Engine Block Heater Failure • Indication is a low coolant temp alarm – Poor cooling system maintenance • Sampling – Circuit breaker to heater is off/tripped – Failed heater element – Heater hose leak – Valves in off position – Heater thermostat adjustment • If equipped (typical setting is 80 to 120)
- 15. COMMON REASONS FOR GENERATOR START FAILURE Leaks – Fuel or Coolant • Coolant leaks – Hose connections and clamps – Radiator core – Water pump • Fuel leaks – Nat Gas/Propane – Diesel: Filters, injection & supply lines
- 16. COMMON REASONS FOR GENERATOR START FAILURE Oil Leaks and “Wet stacking” • Common oil leaks – Crankcase breather, filters, drain plug, gaskets, & seals – Check oil level weekly • Wet stacking – Caused by running on light load – Results in unburned diesel fuel in exhaust system – Load bank testing solution – NFPA and by most engine manufacturers recommend load bank testing – Load bank test assures system performs under load
- 17. COMMON REASONS FOR GENERATOR START FAILURE Air In The Fuel System • Infrequent use – Perform weekly test • Line leak – Visual inspection • Faulty system check valve • Fuel storage tank location • Low fuel
- 18. COMMON REASONS FOR GENERATOR START FAILURE Engine Out of Fuel • Plugged fuel filters with water and contaminants – Change filters annually & test fuel • Mechanical level gauges inaccurate – Visually verify fuel level • Low level alarms failure – check level • System component failure – Check pumps & valves
- 20. COMMON REASONS FOR GENERATOR START FAILURE “My Generator is Running!” • Well-maintained emergency power systems operate automatically • Once utility power is restored the generator continues to run for a short time – delay timer in the automatic transfer switch assures steady utility power is available • Transfer Switch Indicators
