Lesson 2

Wiring a Pico Controller

Timing Relay

Back to our task. In order to extend the circuit diagram for our

conveyor belt system we have to switch to Circuit Diagram View.

As we know from Lesson 1, there are several ways to change views.

We can either use the menu (Circuit Diagram, Circuit Diagram

View) or the tab in the Toolbox. However, there is a more convenient

and faster way of reaching this view. Double-clicking the device is

enough to activate the Circuit Diagram View.

Since the conveyor belt is required to start up with a delay after being

switched on, we shall use the T1 timing relay to create the on-delayed

function. The task definition requires a time delay of 3s.

T1 can be added to the circuit diagram as follows:

1 2 ... 12 13 14 15 16 17 18 19 20 21 22 ... 57 58
