Cause: The voltage drops below 21 volts for 24-volt devices and less than 10.5 volts for 12-volt
devices, and the device detects a low voltage failure if the supply voltage is present for more than 20
seconds.
Device Response: If the device detects this fault in stop mode, it does not allow the system to operate
if the voltage rises and becomes operational, the error goes away automatically and the system can be
started. If such an error occurs while the device is running, the device will send itself to the stop mode
by cooling and the error will remain on the screen.
Troubleshooting:
* Check that the supply voltage from the vehicle to the system is within the appropriate range.
YH 24v - Supply voltage> 21v.
YH 12v - Supply voltage> 10.5v.
* The voltage on the vehicle battery must not different from the voltage on the J9 connector. If this is
the case, please note that the “+” terminal of the battery is in contact with oxidation or contact.
* If the supply voltage is appropriate, reset the device from the button or disconnect the power supply
and then connect again.
E 14 : Low Voltage Failure
Cause: The fuel tank may be out of fuel, the fuel hose may be clogged, the exhaust hose may be
clogged, or the combustion air intake hose may be clogged. The glow plug may have failed and the
fault could not be detected electrically.
Device Response: If the device does not detect combustion in the combustion chamber shortly after it
starts working, it tries to start the combustion again after cooling for a while. If it encounters the same
situation 2 times in a row, it will give the error.
Troubleshooting:
* Make sure the exhaust outlet and combustion air intake hoses are not blocked or improperly installed.
* Make sure there is fuel in the fuel tank.
* Make sure the fuel hose is not blocked.
* Make sure glow plug is working.
* Try to start the device after refueling the fuel tank, if the device does not work in 2 attempts, it will give
the same error again, reset it from the button or disconnect the power supply and then connect again.
E 15 : Ignition Start Failure
Cause: The device may have overheated in any way during operation. The temperature sensor on the
housing or the temperature sensor in the suction line may be detecting temperatures that are higher
than required. If the power is cut off for any reason while the system is operating, this may occur when
the power is turned on again.
Device Response: When the device detects this error, it will go into stop mode by cooling if it is
working. It will clear the error if the device is reset or if the power is supplied and reconnected. If this
error occurs when the device is de-energized and turned on again, all the sensors on the device will
detect high temperature and the error will be displayed and the error will remain on the screen until the
reset is made with the button.
Troubleshooting:
* Make sure that there are no airflow obstructions in the air inlets and outlets of the device.
* Make sure that the pipe length between the device and the blowing grille is within the standards.
* Check the cables and sockets of the temperature sensors on the device.
* If a problem is not observed, reset the device from the button or disconnect
the power supply and then connect again.
