7.Test Running
7.1 Key check project before test running
● Set all the terminal screws tight before running.
● Check all the connection of the terminal.
● Make sure no short circuit phenomenon.
7.2 Test running method
According to “Installation Guide”,make COM1 and WH short circuit;The system situation and
the light as follow table:
NO.
Light
System Situation
1
All the lights flash once
Power on
2
“POWER”light is on
System starts to self-check
3
“POWER + MPPT”light on
Pump starts to run
Remark
：
1
、
If water level sensors are not used,make COM1 and WH short circuit to run the
system.
8.Maintanance Method
8.1 Regular maintanance project
● Every panel’s output voltage is in normal range.
● The tightness of terminal screws.
● Check if there are any dust/iron scrap/mordant liquidin controller.
● Check if there are any noise or shaking of the pump when the system is on.
8.2 Attentions during the maintanance
●Disconnect the input power of controller before maintanance;

circuit of controller;
●Keep the controller clean after maintanance,avoid any dust or liquid invade into the
controller.
