E01
Generator will not start; the control panel shows E01 shortly after a cranking attempt.
Low Oil Shutdown / Oil Level Protection Active
E02
Engine starts but stops within a few seconds; the control panel shows E02.
Fuel Supply / Fuel Solenoid Fault
E03
The generator runs but has no AC output; the display shows E03, and the output breaker will not stay engaged.
Overload / Output Short Circuit Protection
E04
Engine speed fluctuates and the unit shuts down; the display shows E04 (over-frequency / under-frequency protection).
Engine Governor / Frequency Control Fault
E05
The generator shuts down after running under heavy load; the display shows E05 (over-temperature).
Engine Overheating Protection
E06
The generator fails to start in automatic mode; the display shows E06 (starter fault).
Electric Starter Circuit Failure
E07
The generator runs, but the display shows E07, and the output voltage is low (e.g., 150–180 V instead of 230 V).
Automatic Voltage Regulator (AVR) Failure / Under-Voltage Protection
E08
The display shows E08, and the generator shuts down when the ATS attempts to transfer load.
Phase / Voltage Imbalance or Incorrect Phase Sequence (3-phase models)
E09
The display shows E09, and the generator will not enter AUTO mode.
ATS Communication / Remote Start Signal Fault
E10
The display shows E10, and the engine stops abruptly during operation.
Emergency Stop / Safety Circuit Activated
E11
The display shows E11, and the generator cranks but does not fire.
Ignition System Failure
E12
Display shows E12, and the generator shuts down after a few minutes of running under light load.
Fuel Level Sensor / Fuel Starvation Protection
E13
Display shows E13; the generator will not accept a load from the ATS.
Neutral Loss / Ground Fault Detection
E14
Display shows E14, and engine speed surges when large loads are applied.
Load Step / Power Factor Protection
E15
Display shows E15, and the generator stops shortly after mains power returns.
Mains Sensing / Grid Voltage Detection Fault
Symptom
Automatic start does not occur during mains failure, but the generator can be started manually
ATS Start Signal Not Reaching Generator
Symptom
Control panel display is blank, but the engine can still be started manually (if equipped with recoil).
Display / Control Panel Power Failure
Symptom
Corrosion and rust are visible on the alternator and electrical connections, leading to intermittent faults in wet weather.
Moisture Ingress / Environmental Damage
Symptom
Engine surges up and down at no load, hunting RPM
Unstable Governor Operation
Symptom
Excessive black smoke from the exhaust during operation
Rich Fuel Mixture / Incomplete Combustion
Symptom
Excessive vibration of the generator set during operation
Mechanical Imbalance / Mounting Fault
Symptom
Frequent spark plug fouling, engine misfires, and loses power.
Combustion / Ignition Quality Problem
Symptom
Fuel in engine oil (oil level rising, oil smells like petrol)
Fuel Dilution of Engine Oil
Symptom
Generator shuts down after 10–20 minutes of running, then restarts after cooling
Heat‑Related Ignition or Fuel Fault
Symptom
Hour meter and indicators work, but the start/stop buttons on the panel do not respond.
Control Keypad / Switch Failure
Symptom
Loud knocking or metallic banging noise from the engine while running
Internal Engine Mechanical Damage
Symptom
Strong fuel smell around the generator, visible fuel dripping
Fuel Leak
Symptom
The engine cranks normally but does not start, and no error code is displayed.
Fuel and Air Delivery Failure
Symptom
The engine starts but stalls when the choke is opened or when a load is applied.
Lean Mixture / Partially Blocked Carburetor
Symptom
The generator enclosure or frame becomes live (tingling shock when touched).
Protective Earth Failure / Faulty Grounding
Symptom
The generator is excessively loud compared to normal operation.
Exhaust / Muffler or Mounting Issue
Symptom
The generator produces power, but the voltage is too high (e.g., above 250 V) or fluctuates widely.
Voltage Regulation Instability
Symptom
The generator runs but produces no AC power at any outlet, and no error code is shown.
Alternator Excitation Loss
Symptom
The generator starts automatically, but the ATS does not transfer the load to the generator
ATS Transfer Mechanism Fault
Symptom
The generator trips its own RCD or the house RCD as soon as it is connected.
Earth Leakage / Insulation Fault
Symptom
The generator will not start at all; there is no crank and no click from the starter relay.
Control Power / Battery Supply Failure
Symptom
White or bluish smoke from the exhaust, especially on startup
Oil Burning / Valve Stem or Ring Wear
