7. PROTECTION AND FAILURE
7.1 High Temperature Warning and Speed Reduction
In "Auto-Inverter/Manual-Inverter Mode" and "Timer mode" (except backwash/self-priming),
when the module temperature reaches the high temperature warning trigger threshold (81
it enters the high temperature warning state; when the temperature drops to the high tem-
perature warning release threshold (78
The display area alternately displays AL01 and running speed or flow
1) If AL01 displayed for the first time, the running capacity will be automatically reduced as
below:
a. If current operating capacity is higher than 85%, the running capacity will be automatically
reduced by 15%;
b. If current operating capacity is higher than 70%, the running capacity will be automatically
reduced by 10%;
c. If current operating capacity is lower than 70%, the running capacity will be automatically
reduced by 5%.
2) Suggestion for non-first displayed of AL01: check the module temperature every 2 minutes.
Compared with the temperature in the previous period, for every 1-degree Celsius increase,
the speed will decrease by 5%.
7.2 Undervoltage protection
When the device detects that the input voltage is less than 200V, the device will limit the current
running speed
When input voltage is less than or equal to 180V, the running capacity will be limited to 70%;
When the input voltage range is within 180V~190V, the running capacity will be limited to 75%;
When the input voltage range is within 190V~200V, the running capacity will be limited to 85%.
7.3 Trouble shooting
Problem
• Power Supply fault, disconnected or defective wiring.
• Fuses blown or thermal overload open.
Pump does not
• Check the rotation of the motor shaft for free movement and lack of obstruction.
start
• Because of long time lying idle. Unplug the power supply and manually rotate
motor rear shaft a few times with a screwdriver.
• Empty pump/strainer housing. Make sure the pump/strainer housing is filled
with water and the O ring of cover is clean.
• Loose connections on the suction side.
Pump does not
• Strainer basket or skimmer basket loaded with debris.
prime
• Suction side clogged.
• Distance between pump inlet and water level is higher than 2m, the installa-
tion height of pump should be lowered.
• Pump does not prime.
• Air entering suction piping.
Low Water Flow
• Basket full of debris.
• Inadequate water level in pool.
• Air leak in suction piping, cavitation caused by restricted or undersized
suction line or leak at any joint, low water level in pool, and unrestricted dis-
Pump being noisy
charge return lines.
• Vibration caused by improper installation, etc.
• Damaged motor bearing or impeller (need to contact the supplier for repair).
