Hello everyone, Please let me know when we press start button on screen for Motor and Den-ester in auto and manual mode why it is not starting?, which points i have to check for input and output signals from drive. And there is no error on screen. Please refer both electrical drawings. Thanks.

Thanks for reply, To reduce pressure/flow from the pump, it is ok to circulate/pass water from discharge line(@ 7-8 bar pressure) to suction line?

Please refer the drawing and let me know what happens if the pump suction and discharge line bypass together. Thanks.

Thanks

Please See the drawing and Advise...

Hi, i want to make automatic on/off the 3 phase pump with float switch and 3 phase contactor(with auxillary contacts) for my tank. i have, 1. contactor with auxillary contacts(3 phase contactor , a1,a2 coil voltage 220volts, no and nc) 2. Float switch(single phase) 3. with this i want...

Hi, i want to make automatic on/off the pump with float switch for my tank with contactor(with auxillary contact) i have, 1. contactor with auxillary contacts 2. Float switch 3. Manual On/Off switch for pump i want the connection details according to attached diagram. Thanks.

What is the name of this symbols. See Attachment.

1.What happen when we connect 3~ phase star connection 415volts pump to single phase 250 volts power supply?,it gets burn?. and 2.How to check motor winding of any motor with multimeter? Thank you.

1.If i apply voltage 440volts at L1,L2,L3 the K3 (contactor) will get on automatically? 2.How this SSR work and what should be the voltage at 4,5,6 and 7,8,9(X1 terminals)? The main thing i want to ask is how this heating 1 and heating 2 gets ON and OFF and at what voltage? Thank you.
