Chapter 3 Wells water towers working mode

Water level sensing device can be selected according to need. Use a variety of mechanical float or reed
device, as long as they follow the water level fluctuation, but the water level sensor disconnected or short
signal can be. Note that the selected sensors and wiring should meet the level sensor logic setting.
Using only one set of level sensor device case (alone tower or water wells sensing function). Another
group level sensor function is not, and should be handled according to the logic. When used alone tower
water level sensors, Well + and Well-wire shorting should be in the state on behalf of the wells do not dry.
When used alone wells water level sensors, Tank + and Tank-wire should be in the OFF state, the water
is not pumped full of representatives towers.
the pump dry dry run protection
Open the tower well protected mode control RS-P solar water pump controller startup and shutdown
according to the water level ,that is the pump dry dry run protection.
Under certain circumstances, such as: do not use the tower well protected mode, or the failure to protect
water tower well into the dry-running state when anhydrous, anhydrous pumps run dry protection will play
a role, avoid prolonged dry running pumps damaged.
