6.6 Water Level Sensor Connection
Dry protection function:
There have two kinds of detection models, automatic
and manual. Automatic dry protection is achieved through inverter
’s software.
And manual model need water level sensors to input signal through SENSOR
inside Supplier Inverter.
Overflow Protection:
water level sensors are requested to input signal
through SENSOR inside Supplier Inverter.
