STAYING IN CONTROL of harvesting
Sensor-Technik UK has developed the control system for Big Bale Co South’s Transtacker bale harvester. Here the company looks into the requirements and the solutions which ensured that every part of the system worked to the required specification

ensor-Technik UK is a leading integrator for control, measurement and instrumentation systems and has years of experience across multiple industries such as agriculture, construction, automotive and marine. What makes it different is its ability to offer the complete engineering lifecycle from concept and design, through prototyping and beyond to series production. Agricultural machinery has always set
the pace with adoption of innovations and technological advances. As the needs of the end-user develop in both complexity and quantity, the machine must meet all requirements, day-in and day-out. The new breed of agricultural hardware is no longer a tool – it is a vital part of the

commercial success or failure of today’s agricultural enterprises. CAN-bus has long been adopted by agriculture as the primary communications back-bone for a machines-distributed control system. Sensor-Technik UK is a CAN-bus expert, specialising in the design, development and implementation of advanced control solutions using CAN and utilising leading hardware and software to realise the ideas of leading OEMs. Sensor-Technik UK was contracted by
Big Bale Co South –manufacturer of the innovative Transtacker bale harvester – to design and develop a new control system for the machine. As with any system development process, sales engineers from Sensor-Technik UK start

with the concept, sitting down with Big Bale and selecting the required hardware and software functionality. As a result of this design process, Sensor-Technik UK defined the required system components as follows: 1. Main ECU 2. Operator Interface 3. Cable Harness System
MAIN ECU As with all systems, the main ECU is selected based on a number of key parameters – number of inputs and outputs (I/O), number of required CAN connections and programming language. In the case of Big Bale Co South, the required I/O determined the ESX-3XM as the primary ECU for the system. The ESX-3XM is the latest in the long-line of powerful electronic control units
