Domino Premium Full Twist Grip Throttle

Domino - the full twist Throttle for your E-Bike

Original product from Domino (Italy) - designed for motor bikes, but also usable with E-Bikes. For the real Bike-feeling. For use with E-Bike systems, it has to be connected the right way. We will show you how this works.

• Without connectors and 100 cm cable length
• Micro switch max 2A / 24V
• Handlebar tightening torque 1,5 to 1,7 Nm

This throttle uses a linear potentiometer (IP67). In addition a built in microswitch is integrated, which can be connected as brake cut off and/or regenerative braking. A second handle for the other side is included.

Blue: 5V
White: GND
Black: Sensor (Potentiometer)

The green wires are for brake/power interruption - it can be ignored. If you want to use it, you have to connect one of them to the 5V wire.

1) Connection with Bafang BBS01/02/HD or CYC Motors (with BAC controller):

Wiring:

You have to connect a 470 Ohm resistor between Bafang RED and Domino BLUE - otherwise the error 04 is shown very quick (less throttle ramp). If you add the second 100 Ohm resistor between the BLUE/BLACK and RED/BLUE wires, then you can use the full throttle range. This will make the throttle react earlier. If you don´t want this behavior, you can simply remove the second resistor (100 Ohm). You can find the Bafang throttle wiring (same as CYC throttle wiring) in our download area.

Adjust Bafang Controller settings (Throttle):

• Throttle Mode: Speed
• Start Voltage: 15 (=1,5V)
• End Voltage: 45 (=4,5V)

When "Throttle Mode" is set to CURRENT, the throttle grip reacts like a switch - ON or OFF. With SPEED settings, the throttle operation is smooth and can be adjusted with the grip.

2) For Adaptto and Domino:

By using Cycle Analyst V3 you have to set the Fault Volt to 4.99V. 

Some controllers have problems with the full voltage of the poti - a 470/560 Ohm resistor is recommended. There is a connection of the switch, when the throttle is twisted and no connection when released.
