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

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

     CIRCUIT BREAKER
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
COMMON REASONS FOR
    GENERATOR START FAILURE
             Battery Failure
• Charger turned off
  – Check weekly charger operation
• Vibration
  – Check hold down bracket
BATTERY HOLD DOWN & CHARGER
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
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)
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
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
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
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
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
