Troubleshooting method of Electrophoresis code

Electrophoresis machine code failure so that many users worried, many users can not understand the meaning of some code, so as not to start, in order to solve your problem, Shanghai Jiapeng technicians deliberately some common code fault sorting out, I hope to help you.
Er1: The output voltage exceeds the maximum value.
Er2: The output current exceeds the maximum value.
Check if the electrophoresis buffer concentration is too high. Whether the electrophoresis tank is inserted or removed when the electrophoresis apparatus is running.
Er3: Short circuit.
After cutting off the power, unplug the cable of the electrophoresis tank, and restart the machine to see whether the alarm is no longer reported, then it is normal.
Still alarm may chip damage, need to repair.
Er4: Load is not connected.
Check if the concentration of the electrophoresis buffer is too low.
The connecting line of the electrophoresis tank is not well inserted or in poor contact. If you can't fix the cable, fix it.
Er5: Sudden voltage change (possibly a load was removed or inserted).
Er6: Sudden current change (possibly a load was removed or inserted).
Cut off the power supply and start up again. It is not recommended to insert or remove the electrophoresis tank in the electrophoresis apparatus.
Er7: Output power exceeds the maximum value.
Check if the electrophoresis buffer concentration is too high. Whether the electrophoresis tank is inserted or removed when the electrophoresis apparatus is running.
Er8: Set the output voltage to 0.
Er9: Set the output current to 0.
Reset voltage and current data.
Er11: The fan is damaged.
Er12: The fan speed is too slow or stops.
The fan or chip is damaged and needs to be repaired.
Er15: Boot alarm.
Er16: Boot alarm.
It is caused by the failure of normal shutdown during the previous use of the electrophoresis apparatus.
So just ignore it and use it as usual.
Er17: Current monitoring alarm.
If the current is too high or the power is too high
