Wiring & accessories of a Pick-to-Light system

You will learn how to implement the cabling of a Pick-to-Light system. In this article we will explain different methods and possibilities. You will also learn which accessories are required for this.

Supply lines from the controller

The cabling is designed to be very flexible and simple. A single 4-wire cable connects the mounting rails to each other and to the controller. The controller supplies the Pick-to-Light displays with power and data and forms a link between the displays and the control server (LUCA-Server).

Up to 4 supply lines can be connected to each controller via plug-in connectors. The total length of the supply line should not exceed 100m.

Different types of wiring

To achieve great flexibility, the cabling can be serial, parallel or a mix of both. The PTF-BUS has been specially designed to allow a mixed cabling type over long distances.

Serial

With serial cabling, two connection terminals are installed in a mounting rail. One at the beginning and one at the end of the rail. Thus, the rails are connected serially in a row. The end is always connected to the beginning.

The maximum length of the rails and the cables depends on the number of connected compartment displays and from experience should not exceed 200m.

Parallel wiring

In parallel wiring, only one terminal with double design is used in each rail. Two cables are then connected to the one terminal. As a result, the mounting rails are connected to one point of the supply line, as if to a parallel circuit.

Mixed operation

Both of the above methods can also be used in a mixed operation without any restrictions. This feature gives the Pick-to-Light system great flexibility in wiring.
