The brain of the system, DTI (DigitalTech Intelligence), as well as the battery pack, are inside the Power Unit, the system's source of power. This is the heart, brain and the "right hand" (this controls the motors and their operating power) of Campagnolo electronic drivetrain.
The main functions of the DTI are:
monitoring and managing the battery pack.
enabling and monitoring the front and rear derailleur.
signaling any anomalies through the RGB led.
communicating with the interface.
enabling the acoustic buzzer.
Once it has received digital signals from the interface, the Power Unit processes them through a special algorithm and translates them into movement of the rear derailleur and derailleur. The DTI, Digital Tech Intelligence, which is housed inside the Power Unit, continuously monitors the signals that arrive from the interface and the rear derailleur and derailleur, thus managing their operation. The Power Unit, along with the interface, also acts as the diagnostic centre of the system, signaling any anomalies in the system through an RGB led and an acoustic buzzer placed in the Power Unit. The electronics of the system are housed inside the Power Unit. This strategic choice allowed us to make the system less vulnerable to external agents (such as oil, water, mud and dust) and make it stable even when subjected to significant vibrations, such as those generated by professional athletes on the road of classic north routes. This way any errors in the system are dramatically limited and the system is guaranteed to function even in extreme conditions, be it weather, be it terrain. In particular, the special case housing the Battery Pack has been produced in a self-extinguishing plastic material (UL94 V?).
The DTI is equipped with a number of input/output data ports that allow you to check the system remotely and even update the Firmware and Eprom.
The BATTERY uses Lithium ion technology and has unprecedented autonomy.
In STAND-BY mode the system is able to maintain the charge for up to 6 months. To avoid damaging the battery pack, the system turns off automatically when it reaches 9 Volts, to avoid it from dropping below this voltage. If it reaches 7.2 Volts, a special circuit inside the battery pack (PCM) turns the battery pack off to avoid absorbing additional energy and thus avoiding damage to the battery pack.
DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation.
ON BOARD DIAGNOSTIC: The EPS system is capable of automatically detecting a whole range of malfunctions.
WATER PROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.
WARNING - All connection, installation, removal and adjustment operations of the EPS drivetrain must only be carried out by a Campagnolo Service Center, a Campagnolo Pro Shopor a mechanic specializing in the installation of EPS systems. Any Tampering with or incorrect or incomplete installation of any part of the EPS system will automatically void the warranty.
NOTE FOR SPECIALISED MECHANICS - Please remember that all assembly, disassembly, adjustment and maintenance procedures for the EPS drivetrain are described in the EPS technical manual, which is available in PDF format on our internet site www.campagnolo.com.
