Common problems

Wiring Error ALARM 2099
Wi-Fi network connection broken or intermittent
Cause: Various.
Fix: See Wi-Fi module owner’s manual.
Voltage and Frequency Drop Excessively When Loads Are Applied
Fix: TEST 14 - CHECK VOLTAGE AND FREQUENCY UNDER LOAD, BOTH LOW -> TEST 15 - CHECK FOR OVERLOAD CONDITION, NOT OVERLOADED -> GOOD -> IF RECONFIGURED TO LP GAS, VERIFY THAT PROPER PROCEDURE WAS FOLLOWED (REFER TO INSTALLATION MANUAL), GOOD -> OVERLOADED -> DISCONTINUE TESTING, REDUCE LOADS TO UNIT’S RATED CAPACITY, TEST 12 - CHECK STEPPER MOTOR CONTROL, GOOD -> BAD -> REPAIR OR REPLACE, LOOK FOR A SHORTED CONDITION IN A CONNECTED LOAD OR IN ONE OF THE LOAD CIRCUITS, GOOD -> TEST 7 - CHECK STATOR AC POWER WINDINGS, ENGINE CONDITION GOOD -> REPAIR OR REPLACE, BAD -> TEST 16 - CHECK ENGINE CONDITION, GOOD -> GO TO “PROBLEM 18 - ENGINE STARTS HARD AND RUNS ROUGH/LACKS POWER” SECTION 4.3
Unstable Voltage or Incorrect Output Which is Not Triggering a Shutdown
Fix: TEST 1 - CHECK AC OUTPUT VOLTAGE, ERRATIC -> PROCEED TO PROBLEM 3
Unit is set to OFF, but engine continues to run
Cause: Controller wired incorrectly.
Fix: Contact an IASD for assistance.
Unit consumes large amounts of oil
Cause: Excessive engine oil.
Fix: Adjust oil to correct level. See Checking Engine Oil Level.
Undervoltage 1902
Stepper Overcurrent ALARM 2100
RPM Sensor ALARM 1501
Prolonged Over-Voltage Undervoltage 1900
Overspeed ALARM
Cause: Prolonged (60 Hz on a 50 Hz unit, 72Hz on 60Hz unit) Over specified Hz for 3 seconds. Possible cause: Stepper motor/mixer body assembly issue.
Overloaded ALARM 2102
Overload Remove Load ALARM 2399
No transfer to standby after utility source failure
Cause: Generator MLCB (generator disconnect) is OFF (OPEN).
Fix: Set generator MLCB (generator disconnect) to ON (CLOSED).
No AC output from generator
Cause: Generator MLCB (generator disconnect) is OFF (OPEN).
Fix: Set generator MLCB (generator disconnect) to ON (CLOSED).
