· Damage to the circuit board.

Treatment Measures for Abnormal Alarm Information

· Supplement the corresponding reagents;

· Replace the clogged pipeline or reconnect the leaky joint;

· Ensure the unobstruction of the two outlets of the submersible pump;

· Examine whether the peristaltic pump operates normally in both directions. If not, please inspect the connection or replace the pump driver;

· Check whether each channel of the selector valve is unobstructed. If not, please inspect whether the corresponding channel is blocked. If it is blocked, please replace the selector valve. If it is not blocked, please inspect the connection or replace the valve driver;
