EU07 - Can't go faster than 85-90 km/h

[TheFloxiCz]

Hi everyone,

I have small issue with EU07. Sometimes when I forgot to push Vigilance button in time or when I exceed 600A, I'm having issues with going more than 85-90 km/h. I have full throttle and regulator, but the EU07 won't go faster. 

I tried to go step by step with the tutorial posted here, but it won't go faster anyway. I'm posting screenshot, maybe you will see something wrong. 

 

Thanks in advance for the help!

It looks like you forgot to move the regulator back to 0 when you started turning the throttle up as I can see.

Ah, thanks! It works.

No problem 😁

And what should I do when the control "JAZDA NA OPORACH" lights up (orange light)? There isn't any note about that in the manual. With this light you mostly cannot drive.

It means that engines are powerd through resistances, you shouldn't drive on them for a long period of time. When you set the throttle into 28th or 42nd position it should turn off.

You can found it in the EN manual

I forgot about it in instruction. To switch engine grouping, you have to move field shunting lever back to zero. There isn't mechanical block, just on electric side, so in your case contactors were still set to serial non-resistant position. That's why current is shown only on first amermeter as engines are connected in single branch. Going in opposite direction, coming back through parallel resistive positions, you can get unplesant surprise as engines switch back to serial grouping with lowest field, getting sudden kick in rotation speed and current passed, causing slipping and bursting fuses.

This is the process of acceleration:

Note that you need to "notch up" to notch 1 first, wait for the traction switch to cut in (blue light off)

You're now in "series" and only the right amp indicator will show amps. 
then notch up at the max amp (600A) and as high as possible to get out of the resistors as soon as possible. Notch up to notch 28. Not further! Do never "linger" in the notches 1-28 too long. It's always "up and high up". if you linger to long, you're cooking the resistors.

With a 8 car train you might now be at around 40/45 km/h.

then use the "shunt" regulator to notch up step by step, again watching the amps not to go above 600A. go up and go high until notch 6 of the shunt regulator.

Let it go to 60 km/h or even higher. The shunt steps do NOT use resistors. You can linger in any position. (some engine systems only allow you the equal, but not the odd numbers to linger in.

Then go back with shunt regulator to 0 and notch up from 28 further to 43 as soon and quick as possible. In most cases with a medium heavy train, you will be able to do that very quickly. Now you see BOTH amp meters indicating a value. You're now "in parallel". 

Then again use the shunt regulator to go up and high up in the amps, be careful, the steps are huge with the 0-6 of the shunt regulator. Once you're at around 95 km/h, it'll be the last notch. Then just keep it up until speed is achieved.

Maintain speed? whether you use notch 43 (parallel max) and the shunt regulator, or even step back to 28 (series max) and shunt regulator, or go to "off". But nothing in between. 

That's the trick.

In EU07/EP07 (4E, 4Ea, 303E, 303Ea, 303Eb and 303Ec) had 600/650A as a max amp, but if we switch into the "Wysoki rozruch" it will be raised into 750A. Only EP09 (104E, 104Ea, 104Eb and 104Ec) had the 800A as a basic amp. 😉
