3. Inaccurate setting of thermal power cutter parameters | 3. Reset the thermal relay circuit parameters | ||
high temperature | High temperature lights on | Pool lacks water | Adjust the pool ball position |
Automatic liquid level control does not work | Manual work normally and automatically not working | Float fault | Replace the float |
Auto-decompression decompression is not working properly | The auto-coupled decompression can be started, but cannot be converted to full-voltage operation, and the startup time is long, so the decompression power supply is cut off in a time-delayed manner (protection circuit operation) | 1. Current~time conversion relay fault | Check carefully, replace |
2. The intermediate relay coil of the conversion circuit is damaged | |||
3. The contactor is damaged | |||
4. Time relay coil is damaged | |||
Auto-decompression decompression does not work | Cannot start the motor | 1. JD1-A coil is damaged | Check carefully, replace |
2. The time relay is damaged | |||
The backup pump cannot be put into automatic | 1. The main pump for submersible sewage pump is damaged, and the backup pump cannot be put into automatically. | 1. The backup pump controls the float ball damage | 1. Replace the float ball |
2. The main pump is damaged, and the backup pump cannot be cut into operation automatically. | 2. Fault time relay (AH3-3-10S) | 2. Replace the time relay | |
Y-△The pressure reduction does not work | 1. The motor can be started, but cannot be converted to full-pressure operation | 1. The conversion time relay is damaged | 1. Check carefully and replace |
2. The motor cannot be started | 2. The contactor IXC is damaged | 2. Check carefully and replace |
