Well understood but I have a question on the Number 8 which is latch,preset,Number 9 common which is neutral, then 10 setup delay and 11 faulty restart delay please shed more light if possible
Hi Michael. If you lose one phase the relay will not switch on. The relay sould be connected to the pump contactor or mains contactor thus not allowing the pump or main power to switch on.
I came because my electric scooter through a fault saying “motor phase fault” but the motor wire is connected fine. For some reason it delivers more power to the front motor than the rear , idk what’s going on
Hi. I do not have a lot of experience with Electric Scooters but if you see no wire that is loose outside the motors,you're only other options are to open the motor and check for a loose wire inside the motor. If no wires are loose then it can only be one of the coils that burnt and that you can have rewire at a shop if it is worth the cost. Otherwise a new motor might be an option. Just check the switch/throttle as well before scrapping the motor.
Will the contactor turn on really? Because i am not seeing neutral supply connected to any of the contactor coil( A1 or A2). You've only supplied blue phase directly to coil A1 of the contactor and another wire taken from port 3 of phase failure to A2. Where is neutral taken to? I need help plz
Hi. The only reason to put a phase failure/phase reversal relay in your main DB or for pumps is bacause it is 3phase. To connect a neutral wire would mean a single phase connection and it would not be necessary to put a phase failure in a single phase connection as there would be no damage as in 3phase if the one phase drops.
@@p0we111 I'm referring to the contactor, sir. The wiring of phase failure I understood very well. May be I don't understand the concept of contactor in this scenario. Because I have always known that for the contactor to be energized, it must be supplied with phase at A1 and neutral at A2 or vise versa but for this case contactor is supplied with 2 phases
@@Le_vis254Hi. Yes you are correct in your observation. A1 is a phase and A2 is a phase. This is a 400vac contactor where the one you speak of with the Neutral is a 230vac contactor.
Thanks nice and quick and to the point
The wire on top where can connect
When it shows over voltage and under voltage at the same time what could be the fault?
Thank you

Hi quick question So what will happen if you loose one phase in the supply of the relay ?

@@p0we111 ok sir, so in 400vac contactor we connect phase to both A1 and A2?
@@Le_vis254 Yes. Connect a different phase to each A1 and A2
Do you have to use a contactor?
Hi Ross, Yes. Unless you are planning on using a very small load,like indicator light or similar only.
@@p0we111 Thanks for the reply! Much appreciated.
