Care and maintenance
Fault code or fault description
E-1
：
thermal fuse fault
Likely causes of the faults
1. In case open circuit fault occurs to the heating core, replace it.
2. In case poor contact occurs to the heating core, unplug and then
re-install it.
3. In case the internal connection cable inside the heating core & handle
is broken or heating core connection contact piece is damaged, repair the
broken lead wire or replace the soldering pencil.
E-2:sensor alarm
1. In case the heating core is damaged, replace it.
2. In case open circuit occurs to the lead wire of the Sensor, check the
lead wire of the soldering pencil.
E-3:zero-cross detection
abnormal alarm
Send to the designated after-sales service outlet for maintenance.
E-4:abnormal temperature
alarm
In case the heating object loses heat too fast, which cannot reach the set
specified temperature even being heated for a long time. You need larger
power soldering equipment.
E-5:over-current protection
1. Short circuit occurs inside the heating core.
2. In case short circuit occurs to the internal lead wire of the soldering
pencil, please replace the soldering pencil
E-8: abnormal soldering
Tsui temperature
1. In case the temperature sensor is abnormal, please replace the heating core.
2. In case the soldering head temperature is too high, please cool the iron
head and then restart the equipment.
E-9: soldering Tsui handle
status
1. In case the handle is not compatible with this equipment, please
replace it with the handle produced by the original factory.
2. In case the internal circuit is abnormal, please send the equipment to
the designated after-sales 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.
Mojibake:
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.
E-6:abnormal system voltage 1. In case the external power supply voltage is abnormal, please check if
the input voltage of the product meets the requirements.
2. In case the host of the product is damaged, please send it to the
designated after- sales outlet for maintenance.
