MMBT2222A a general purpose NPN transistor. data sheet link is below http://www.s-manuals.com/pdf/datasheet/m/m/mmbt2222a_compact.pdf

The various rates of flashing are error indicator codes and should be explained on the charger case. They are for the condition of the battery's though and not the charger. It sounds like the charger itself is bad. Can you return it for a replacement? Is it still in Warranty? For whats its worth, I went from Milwaukee tools to Bosch to De Walt before being satisfied with performance. I hope this helps.

VFD is a device used for speed control of 3ph induction motors & automation process control

Hi, here is the link for the instruction manual.http://www.nodevice.com/manual/Hitachi/page69.html orhttp://www.diagram.com.ua/english/catalog/eng-w-video/h/eng-w-video-h.php?row=718

yes mostly from the cable

Amps don't 'put out' 8-ohms; they're spec'd to drive a nominal load, usually 8-ohms, and always have some leeway as speakers are reactive loads that will vary with frequency.

You need to evaluate what your amp can do with a nominal 4-ohm load. The manual says they will work with amps rated for 4-8 ohm loads. Plug them in and keep an eye (and ear) out for any sign of stress (heat, distortion, smoke) when driving them hard.

Click on this. It is the online instruction manual for that humax pvr9150t

you didn't indicate what model number. ON a L200 for example E21 means over temperature. You need the model number

For a quick reference on the L200 WHAT MODEL DO YOU HAVE? The .3 would be it's status when the fault occured. 3 means constant speed. Are you overloading the drive?

This link is for a L300 for example

That is not a very clear question. When you say interupt drive power,d o you just want to stop the drive? or do you want to render it safe to work on. To stop the drive removing the drive command signal is fine. or look at the wiring diagram and connect some type of stop button. The drive will stop in whatever mode you programmed it for (coast, braking etc) To render it safe for somone to work on it would require a lockable disconnect switch that can be locked in the open position with a padlock (standard fusable or nonfusable disconnect) If you don't have your manual, you can download one here: http://www.inverter.co.uk/applications/hitachi.htm

Ther are settable ramp up and ramp down times and there are settable speeds (max and run)

test, locate and remove fault

Please go to the Hitachi site and download the user manual..it will explain in detail how to increase the speed

I really don't know what machine you have, but i can supply you with a hudge range of service manuals, and other manuals for the Hitachi Inverters.

Hope this finds your answer for ya in one of the correct manuals, or some of the other documents. Without the model you have its hard to go into detail.

the internal fan in the unit is need to get cool down as its motor get really hot .due to short circuit the motor gets a bit short so it has to be checked .because if the motor is getting short this will spoil the unit.
check out.keep updated.thanks.

Check the current limit setting and make sure it can pull 100% motor name plate FLA (amps) If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c
