BALANCER COMPONENTS

3.1 INTRODUCTION

The balancer is manufactured with the following main components:

Ø

IBP BOX

Ø

VIBRATORY ASSEMBLY

Ø

BRAKING SYSTEM

Ø

SAPE ARM

Ø

SONAR

Ø

LASER POINTER

3.2 IBP BOX ASSEMBLY

The IBP box is a multifunctional device used to make running the Vibratory System and consists in a unique electronic
board that intgrates Controller and Power Supply. This IBP board allows an easier maintenance because it consist in
a single board that includes more functions and easy software installation or update, since it can be done via MMC/SD
card.
Software installation or update on all kind of balancers with new IBP board can be done with a unique MMC/SD card
because the software downloading is automatically performed according to the type of keyboard installed on the ba-
lancer.

The IBP box controls:
•

Power supply 5 VDC.

•

Potentiometers.

•

Motor capacitors.

•

Motor.

•

Sonar sensor.

•

Laser pointer

•

Touch screen

The IBP board contains a processor and the memory on which is running the Kernel or BK.
The Kernel is the group of instructions that allow to the wheel balancer to perform the balancing operations
