3. Function
Load Break Switch (220V/380V) is provided, able to control motors of 3HP
single/three phase, 5HP single/three phase and 7.5HP single/three phase.
Under automatic model, microcomputer could receive the signals of flow rate and
pressure and control pump starting up and shutdown.
When the pump runs idle, the sensor system would initiate the protective mechanism
for motors.
When red indicating light is on, it means the cleaner is energized normally. When it
blinks on the other hand, it means the pump runs idle (suck in air without water) and
the automatic mode is locked in order to prevent running abnormally.
When yellow indicating light is on, it means the cleaner has run for 300 hours and it
is needed to change oil.
