Product description
Level Control box used for control and protection of submersible water electric pumps used in the supply of pressurized water and in irrigation systems.
Applications
Control of water level in artesian holes or tanks
Electro-pump protection against lack of water in the hole or well
Protection against short-circuits by a circuit breaker – 16A
Protection against overloads by an overload relay – IP54 IK07
Operation
Make the connections with the switch on (off).
Thermal adjustment according to the rated motor current.
Switch the switch to automatic (aut).
After contacting the P11 and P12 contacts, the contactor will arm when the water level reaches the upper level probe (green LED N.A. – high level), turns off when the contact pair P11 and P12 open, or if the level of Water goes down in addition to the lower level probe (it clears the green led – low level).
If the control circuit switch is in the manual (manu) position, the pump switches on regardless of the control status of the contact pair P11 and P12 and the level condition.
In case of tripping of the thermal relay (overload), the pump switches off (red LED D.T. on the level relay), regardless of the information provided by any of the other controls.
