9-angen magnetian fault code
1. Fault code e0
Internal circuit failure alert:
When internal circuits fail to function properly, the number of digital displays shows “e0”, while the beeper beeps at a frequency of one second. The alert is not self-deactivated, and it needs to be switched off manually before it can be turned off (if e0 is still displayed, go to the maintenance site for inspection)。
E0: internal circuit failure
Checks whether the internal line lined and the lined lined off。
Checks whether the components on the plate are intact (e. G. Electrical resistance to burning)。
Check the welds (welds, welds, etc.)。
Touching cpu, lm339 overheating (after power cuts)
Let's start with the two ends of the wheel
Check if +5v, +15v is normal
Is the lm339 pressure normal
Measurement of the normalness of four high voltage resistance r21-r24 (dismantling)
Check if the q12-q15 triodes are punctured or open, etc
Two, trouble code e1
The electromagnetic furnace, regardless of its working state, closes the output as soon as it detects the absence of a boiler, the inappropriate material of the boiler, and the object of the heating is a small object, and constantly repeats the test of the boiler, while the digital tube displays “e1”, the beeper beeps at a frequency of one second. If the pan is continuously abnormal within one minute, the alarm is automatically shut down after one minute; if the pan is returned to normal within one minute, the failure alert is automatically withdrawn and the original working state is restored (if e1 is still shown, go to the maintenance site for inspection)。
E1: the size of the pan, the material is not suitable or not calibrated
It's iron material.
Three, trouble code e2
Igbt's overheated
When the igbt overheating (over 100°c), the output is closed, the digital tube displays "e2" and the beeper beeps at a frequency of 1 second. This state of alert cannot be automatically withdrawn and a manual shutdown is required for exit. To return to normal temperature and to work manually (if e2 is still displayed, check the network)。
E2: supertemperature or ntc failure (igbt)
(b) e2 after heating; whether the fan turns, whether the speed is low, etc。
Four, trouble code e3/e4
Overpressure, unpressure failure alert:
When electrical voltage is abnormal, the machine immediately stops heating, and the digital display area displays a malfunction code (the voltage failure code “e3” when the grid voltage is higher than 270 v, the stress failure code “e4” when the grid voltage is below 160 v), while the beeper beeps at a frequency of 1 second. When the voltage returns to normal, it automatically exits the malfunction alert state and returns to its original working state. 21t, 23t, 19tk master plate in 07 and 21td1 voltage design low of 100, recovery of 110v, high pressure of 285v, recovery of 280v in 08。
E3. E4 in an electromagnetic furnace
Users appear at e3/e4, first to test the normality of the power grid in the user's home; we meet a ceiling of 265 v ~ 275 v and a floor limit of 150 v ~ 170 v (a wider range after 07); for example, the normal occurrence of e3/e4 for high-pressure protected circuits, most of which is caused by high-voltage resistance (separation) variations (if e3/e4 is still shown, go to the network point of repair)
