Manual del automotor Impuls 2

[jmluengor]

Pongo a disposición de los aficionados hispanohablantes el manual en español de este moderno automotor. Lamentablemente, no he sido capaz de dar con la clave para circular en doble composición con él tras haberlo acoplado. Quizá alguien lo consiga y, cuando así sea, lo reeditaré y pondré a vuestra disposición.

Acabo de actualizar este manual porque olvidé añadir el apartado relacionado con el cambio de cabina cuando conducimos una composición doble. Esto es algo que hace falta conocer para efectuar algunas actividades en las que seleccionamos 2 x 36Wed Impuls 2. Perdonad la omisión.

Gracias por compartir este manual, y el resto de los diferentes hilos.

"(...) Es posible acoplar dos automotores Impuls 2 para circular en mando múltiple, pero no es posible que ambos vehículos
funcionen sincronizados como un único vehículo a la hora de acelerar o frenar. (...)"

It is possible to connect two Impuls 2 units so that both units operate synchronously as one unit during acceleration or braking:

After coupling, the Quick Disconnector (Disyuntor) in the second EMU (the one being coupled) almost always automatically deactivates. It must be reactivated:

And in the second EMU (the one being coupled) almost always a red icon and the message "Runaway movement" ("Deslizamlento") appear:

 

The brakes are then locked and the train cannot move (Maneta 0% and Potencia -98%). The graphic below shows the first EMU, but in the second EMU it looks identical.

You must clear this message to release the brakes on the second unit. To do this, click the field with the Driver ID, then click the same field labeled Level SHP in the next step. The yellow ETCS button on the pulpit will start flashing. Click it (or press Shift+Spacebar). This will release the brakes on the second unit.

When changing direction and cabins in a double Impuls 2, it is important that the pantograph selection switch on the rear wall of the cabin is set to "0" in both rear cabins (looking in the direction of travel) of each EMU. In both front cabins, it should be set to "2" (rear). This is important to remember when shunting, because when changing direction, the rear cabs become the front cabs, and the front cabs become the rear cabs. When changing direction, you must enter each of the four cabs to adjust the pantograph selection knob. And in each of the three inactive cabs, the Power and brake handle (the left one) must be set to "0%" and the Service brake handle (the right one) must be set to the "Drive" position.

One more important thing to note about using cruise control: it's probably a model error in the simulation, but with a dual Impuls 2 EMU, the cruise controls in each unit operate independently!

Example: You have to enter a platform and use cruise control set to 25 km/h. Next, you need to change direction, pick up passengers, and head out onto the track at, say, 100 km/h, also with cruise control. If, before changing direction, you forget to turn off the cruise control in the cab where you entered the platform, leave it on at 25 km/h, then move to the second EMU and set the cruise control to 100 km/h in the new cab, you won't be able to accelerate faster than about 35-45 km/h. The electric current in the first EMU will increase, but the electric current in the second EMU will decrease and reach negative values. The first EMU will try to accelerate to 100 km/h, while the second EMU will try to maintain 25 km/h 🙃

If you're using cruise control while driving a dual-mode Impuls 2 EMU, remember to always turn off the cruise control in the cab you're leaving before changing cabins!

This afternoon I will follow your instructions step by step and will share the results later. Thank you so much for your detailed explanation.

"A picture is worth a thousand words."

I've followed your instructions twice, and both times I've managed to couple the two railcars and drive them together. Interestingly, when I started driving from vehicle A (the main one), the motor amperage was negative in vehicle B (the one I coupled to). When I switched to the cab at the other end of vehicle A (to reverse the direction of travel) and set the selector on both pantographs in the rear cabs of each railcar to 0, the amperage was then the same in both vehicles.

Thank you for your invaluable help.

That's true! 😃

The pantograph selector switches in each of the four cabs must be checked and, if necessary, adjusted correctly every time. This applies to every change of direction and cabs during shunting, and even when starting a deactivated double Impulse 2.
In each of the two rear cabs of each Impuls 2 unit (the rear ones - looking in the direction we will be driving after changing direction), the pantograph selector knob must be set to the "0" position. Similarly, in each of the two front cabs of each Impuls 2 unit (the front ones - looking in the direction we will be driving after changing direction), the pantograph selector knob must be set to the "2" (rear) position.

I only encountered negative amperage values in the second unit when, after completing the last shunt, I left the cruise control on (by forgetting) in the second unit.
Before changing direction (and therefore before changing cabs and Impulse 2 units), it is essential to turn off the cruise control in the cab of the unit you are exiting!

So if you see a negative amperage in the second unit and can't accelerate above 35-45 km/h, check the pantograph selector knob in each of the four cabins of the two Impuls 2 units and make sure the cruise control isn't engaged in the second unit. Also, remember that only one cabin can be active at a time.

One more important thing about changing cabins: 
In the Impuls 2 (whether in single EMU unit or double EMU units), when changing direction, there's no need to lower the pantographs. 
When you deactivate the cabin you're exiting (none of the four cabins are active at that time), the Impuls 2 automatically raises both pantographs (in each EMU unit) for the time needed to transition to the new cabin. This means the Quick Disconnector (Disyuntor), compressors, and converters will be powered on in this time. And in the new cabin you won't have to turn everything on again. The pantographs will automatically adjust themselves correctly (according to the pantograph selection knobs) when you activate the new cabin.

I've found the culprit, although mateusz424 had already warned me about it: the cruise control!

Once the two railcars were coupled, the pantographs were correctly configured and the circuit breakers were checked in both units, the correct data was entered into the DMI screen... for some reason, on the second Impuls 2 unit I was supposed to couple, the cruise control was set to 5 km/h, and it proved impossible to deactivate it (neither via the keypad nor using the cruise control button on the combined Regulator/brake lever). After several attempts and seeing that it was impossible to deactivate the cruise control, I decided to set it to 60 km/h and do exactly the same on the first unit (the one I would be driving from). That was it. The double train behaved as a single unit.

I am very grateful, mateusz424.
