Fault code or fault
description
E0: Abnormal fan
Likely causes of the faults
1. The fan fails to rotate.
2. The fan sensor is damaged.
3. Poor contact.
E1: Open circuit of heating
core
1. The heating core is damaged; replace the heating core.
2. The sensor lead is in open circuit; inspect the soldering pencil lead.
E2: Open circuit of sensor
Poor contact of air gun connector or handle.
E3: No zero-cross signal
The zero-cross sensor is damaged or the mains frequency is wrong.
E5: Over-current output
Internal short circuit of heating core.
E8: Over-temperature
protection
E7: Short circuit of sensor
1. The temperature sensor is abnormal; please replace the heating
core.
2. The temperature of heating core is too high; after the heating core i
s cool, restart the machine.
E9: Abnormal handle
1. The equipment doesn’t support the handle type; please
use the original product.
2.The internal circuit is abnormal; send the equipment to the
designated after-sales service outlet for maintenance.
Screen display fault:
In case the problem occurs, you can try to adopt the following
measures to solve it.If the problem still cannot be solved, please
return the equipment to the original factory for inspection.
1. Check if the socket switch is on.
2. Check if there is voltage on the socket.
3. Check if the plug with the power line is loose.
4. Check if the fuse is damaged (if so, please replace the fuse
according to the specifications)
Inaccurate temperature:
1. Use user temperature compensation function to correct the
temperature.
2. Replace the heating core with one produced and sent by the
original factory.
Display of messy code:
1. In case there is strong interference source from the outside
environment, please change the application environment or
evacuate from the interference area.
2. In case the internal circuit is abnormal, please send the
equipment to the designated after-sales outlet for maintenance.
E6: Abnormal voltage
1. The external supply voltage is abnormal; please check whether
the product input voltage conforms to the requirements.
2. The product host is damaged; Send the equipment to the
designated after-sales service outlet for maintenance.
The short circuit occurs to the temperature sensor in the
