SFR1 Installation Help

[cruuzernz]

Hello Forum Members
I am hoping for some help from this forum please.

I am currently building an Articulated Dump Truck.
I am using a
Beier SFR1, using S-BUS
Flysky FGr8B receiver
Paladin 18EV transmitter
Lipo 3s Battery
I have got the 6 drive motors hooked up and operating on the motor output.
However, I am unsure how I should hook the steering motor, which has micro end-switches and diodes to limit how far it can turn.
It also has two Lifting actuators for the dump tray.
To get the steering motor and actuators operating, should I use a seperate ESC for each and then plug them into the receiver or can I bypass the ESCs and plug them straight into one of the Props on the SFR1 and programme through the Sound Teacher.
I have attached a pdf of the electrics.

Any advice would be appreciated.

Hello Wayne,

To get the steering motor and actuators operating, should I use a seperate ESC for each and then plug them into the receiver

you will need seperate ESCs for this.

The ESC for the steering motor can be connected to the steering servo output (X5/L). This way you can make use of the optional SFR-1 features that affect the steering (inertia, interval steering and angle limits).

The ESCs for the actuators can be connected to Servo 1 and Servo 2 outputs (X5/1 and X5/2). Use "Direct control with:" and the desired Prop channel for proportional / speed dependent control.
If the ESCs are connected to the SFR-1 you can e.g. trigger a hydraulic sound whenever the actuator moves or is not in the home position.

Alternatively connect the ESCs directly to the receiver.

Note: If any of the separate ESCs has a built-in BEC you must pull the red wire from the servo plug and insulate it!

... or can I bypass the ESCs and plug them straight into one of the Props on the SFR1 and programme through the Sound Teacher.

That won't be possible and should not be attempted.

Thank you for your fast response

I have Hobbywing 1060 Brushed ESC's. It doesn't mention a built-in BEC. I assume these will do the job for both and I don't need to pull the red wire as described?
Again thank you for your help.

The Hobbywing QuicRun 1060 Brushed does have a BEC, so you need to pull the wire.

I continue to have problems with my install of the SFR-1 into my Articulated Dump Truck project
I have the 6 motors connected to the motor wires on the SFR-1 and I can control the forward direction thru channel 3 on my transmitter the but I can not get it to go in reverse on channel 3.
I have plugged the ESC’s for the steering motor and Lifting actuators directly into the Flysky FGr8B receiver and they are both working as required
Any ideas to get this vehicle going forward and backwards through the SFR-1 would be appreciated

Have you activated the brake function on the speed controller?

If not, please run the throttle channel setup again using the blue button.

Hello Wayne,

this may not be the cause of the problem but it looks like the 2 Quicrun ESCs have the red wire in the servo cable connected to the receiver and there is a patch cable between SFR-1 and receiver. Therefore all BECs are connected to each other via the receiver. As mentioned above this is not recommended:

Note: If any of the separate ESCs has a built-in BEC you must pull the red wire from the servo plug and insulate it!

This applies to any ESC with BEC connected to the receiver and/or the SFR-1 servo output.

Only one power source (BEC) should be connected to the receiver, typically the strongest one is selected for this, unless the ESCs with BEC are identical and the manufacturer specifically allows to connect them together.

Greetings from New Zealand.
I thank you both for your input. It has helped me solve the problems I was having.

Andy, the reset of the SFR-1 helped and I now have full forward and backward motion.

Rascal, I had followed your initial instructions by removing the red wire from the ESC plugs and insulating them.
Neither of the ESC’s when plugged into the receiver powered up. It wasn't until I put the red wire back in place that the units came to life.
I’m not sure what I have done, differently in my wiring setup but it is all working.
Thank you both again. Your work is much appreciated.

Wayne.
