What fault is it indicating,and where are you located.

They normally use the same password. If that isn't the case,then check further.

@@John-qr4kf awesome i worked around the lock, it was the correct code i found it in the book not long after this comment but still didnt allow me to alter parametres

@@angusbarker5733 In some cases,i have seen the saved code appearing once you take the right route. Maybe that isn't your case. I wish i was somewhere near the VFDs,i will there in a months time,i am stationed elsewhere.

@@angusbarker5733 Though if i get any more information i will definitely let you know.

@John-qr4kf no stress mate if it comes to it again ill bd advising switching to another brand i normally use bosch as theyre simple and repliable

@@AkashKarche-r9n If your damper doesn't have any mechanical issue,which you can test by opening manually,then the Belimo Actuator would open it easily. But confirm the wattage from the dealer when purchasing .

It can open your desired percentage depending on your setting and the angle at which you fix it.

OCT is over Current. You can check your motor. Check the output cables whether there is a short.

@@John-qr4kf saya sudah mencoba melepas kabel ,tanpa motor. Inverter tetap masih kode OCT

​@@ozilh2826Incase you have disconnected both the motor and the cable and still the OCT indication is there,then the IGBT (SCR/Thyristor) are faulty.

@@eng.sayidabdilahi3730 I have used several brands and i have found them suitable. Preferably i would recommend Schneider. ATS 22.

@@John-qr4kf thank you very much Sir. Same rating as the motor (132kW) or slightly higher? I mean the soft starter rating.

@@eng.sayidabdilahi3730 Slightly higher in rating is recommended since it can withstand much,hence it will last longer.

@@MahdiAbdelmaksoud-g3g Check control power.

@@meherphilippo1670 I am sure you have tried to disconnect the Load (Motor). You have tried several times to switch off and on the incoming supply,but still the fault remains. We had a similar fault,(I wish i can share the photos with you),and the fault is also not shown in the Eaton manual book. I believe you are only left with one option,replacing the VFD.

I worked on it only once. To be honest i do not know much about it.

@@UmaShankar-mu6iq You need 0-10v dc reference

Do you want ramp up and ramp down time?

Is it h 01 or o i,because in eaton dc1,i cannot trace h 01,but there is o-i,which is basically an overload. Is your vfd dc1.

First check whether the Contactors are engaging and the Fuses are not burnt. Check the condition of individual Capacitors,whether you have Current flow through the 3 cables connected to the Capacitor. If the above conditions are ok. You can upgrade the steps. Let's say,if it is 20kvar,you can upgrade to 25kvar. The 3rd step onwards,you can upgrade to 50 kvar (25kvar Capacitors connected in parallel from the same Contactor or two different Contactors from one step ),but in this case,the fuses have to be upgraded,the incoming Isolator,busbar or cables too.

Hi,you have already answered yourself,you just charge manually like i have shown at the start of the video,and that basically is a reset.

but it is better to use the resetting terminal inside the mccb

​​​@@markstv7434we don't have a reset button,but in essence,when you are charging,at the same time you are positioning the mccb on off position. And for safety reasons,a reset is always done in off position,so that you can check your fault,rectify and then you switch on. Electrically,you connect your neutral at A1 and your live part at B2 +B4 and it will charge and switch off at the same time.

@@markstv7434 And please like the video and you can as well subscribe.

My brother,why ''Oh Lord''. Is it out of excitement or disappointment.

Thanks

Just follow upto part 8,thanks.

Thanks

Thanks Norah.

It's upto part 8. There is alot of information that i have shared. Just consider subscribing and thanks.

Thanks

And where is your like 👍🏽

Thanks bro

Thanks Shimul

Thanks

Sure,i am still around

There isn't any calibration. It's only the settings of the rotation and the outgoing limit switch,which is done by adjusting the buttons as explained.

@@John-qr4kf sir can do calibration for that damper motor and you know how to calibrate?

PHF simply tells you,the soft starter is not connected to the Load (Motor).

@@John-qr4kf sir I checked the connection it's probably connected to the motor still show the error PHF. What to do?

Then there must be a fault from the internal control connections in the soft starter. Check also the condition of the SCR (Thyristors). You must get a reading of 50 kilo ohm to mega ohm.If there is no reading,then the thyristors are gone.

Share with me your email address so that i can draw the circuit diagram and send to you.

I need drawing pls sir

​@@rathinavelsomu3057I need your email address so that i can send the drawing to you.

Thank you so much my friend Norah.

If it never exploded while it has bn working all along,that means it has no leakage. It was just a period service where we have to test the capacitors whether they can charge and recharge.

It has bn quite some time since i worked on ABB VFD,but you check Parameter 9913'i am not sure but i will confirm and let you know.

@@John-qr4kf thanks 👍🏻

My pleasure
