System distress of pump
motor controller
1. The processor
discovers illegal and
reduntant data;
2. The processor inside
the controller fails;
3. The processor
discovers the switching
signal exceeds the
threshold by 100ms (if
the fault occurs
repeatedly, please
check if the switch gets
wet or damaged).
1. Check the internal micro-processor for
damage;
2. Check input signals of all switches, and
ensure the switches free of wetting or
damage.

Motor matching failure of
pump motor controller
Description of motor matching
failure codes:
0=Normal;
1=Encoder signal received,
pseudo not identified, manul
setup of the encoder pulse
required;
2=Motor temp sensor failure;
3=Motor high-temp response
failure;
4=Motor overheat response
failure;
5=Motor low-temmp response
failure;
6=Low-volts response failure;
7=High-volts response failure;
8=Controller fails to detect the
encoder signal;
9=Motor setup exceeding the
range
Check the encoder and motor and ensure
correct wiring
