Z-DEFENDER is an innovative electronic panel essential to start, run and protect the single-phase ZDS submersible pump against many possible installation and operation faults.
It's special and unique as it doesn't need any setting or self-learning, it's easy to install and ready to use, you only have to select the type of motor on the display and turn the pump on.
Z-DEFENDER is designed to guarantee an optimal protection of the submersible pump against many possible installation and operation faults: an alarm will be shown on the dispaly in case of current overload, low voltage or high voltage, too frequent starts and stops and dry running; ensuring a high degree of automation and restoration.
Z-DEFENDER allows to continuously monitor the submersible pump, guaranteeing its operation in the most efficient way through a Soft start procedure (first start attempt with low starting torque) and if needed, a Strong start procedure to benefit of more starting torque.
Z-DEFENDER allows to continuously detect and monitor in real time the power: the electrical parameters obtained are processed by a special software, which will efficiently guarantee the correct working conditions. With Z-DEFENDER, the submersible pump can work and be continuously protected also when the supply voltage values are at tolerance limit, providing the effectiveness of the protection operation. In addition, Z-DEFENDER, thanks to a “smart software” at variable time and automatic restart, can ensure the optimization of water withdrawal from the borehole or tank when the pump is dry running. Z-DEFENDER also minimizes energy consumption when the pump is not running.
Thanks to its special and innovative ZDS technology, Z-DEFENDER combines, in a single device, protection, reliability and ease of installation.
Z-DEFENDER for H3 and O3 motors it's equipped with 2 capacitors: the first capacitor does guarantee a higher starting torque to the motor, the second capacitor optimizes the motor's efficiency during its operation.
Characteristics
-
Ready to use: doesn’ t need any further calibration or setting up, as it's only necessary to select the type of motor on the display
-
LCD display for easy diagnostic of running parameters or eventual protections
-
Soft start technology
-
Extra torque on start up when necessary
-
Sounder alarm in the event of a fault and in stand-by
-
Double capacitor predisposition when used with H3/O3 motors: one for more starting torque and one for running
-
When the pump is not used, even if it is in stand-by mode, weekly start-up will be commanded by the electronic, in order to avoid any blockage caused by natural sediments in the well
-
No energy consuption when in stand-by
-
Low voltage input for floats or pressure switches
