#MuesliPLC (wired)

Today, I finally created the circuit diagrams. Until now, there was only my scribbling.

Screenshot from the CAD program showing the created main circuit.

Fancy a bit of PLC? No?

Never mind, here we go!

A wider view of an industrial CNC machine setup in a factory. Large black cabinets house electrical and automation components, while pumps and cooling systems are visible in the foreground. The factory ceiling with lighting and ventilation systems can be seen.

I should get in the habit of showing the completed projects...

An electrical control cabinet with a gray metal door. On the door, there are several controls:

at the top, a red fault indicator light and a green operating light (which is illuminated). Below them, two buttons for exhaust ventilation—one red for "OFF" and one green for "ON." In the middle, there is a large emergency stop button with a red knob and a yellow background. At the bottom, a main switch with a red rotary handle and a yellow safety cover.

The control cabinet is mounted on a wall.

The image shows the inside of a wired control cabinet.

On the inner side of the door are the contacts for push buttons and signal lights, neatly wired and secured. Inside the cabinet, terminal blocks, motor protection switches, airflow monitors, zener barriers, and a 24V DC power supply are organized and connected on DIN rails with cleanly routed wiring.

A workbench with extraction through the perforated sheet. A motor is connected to the machine. There is also an emergency stop button and a control panel with an on/off switch, as well as an indicator light for release. All components are suitable for the explosion-proof area.

This is what the exhaust control system looks like with the control cabinet housing and door.

This is what it looks like when it is 'programmed' #Hardwired

I love wires

As in the previous picture, only with many more blue wires.

The cable tray and DIN rails are riveted in place, and I've started with the wiring

From this point on, I had to plan and draw the control circuit. Of course, it will be properly done in the end. But for now, the sketch will have to do.

Basically, it's like PLC programming with ladder logic, just with real wiring.

Various components on a mounting plate.

Visible are motor protection circuit breakers with auxiliary contacts, circuit breakers, DC power supply, relays, airflow monitoring modules, Zener barriers, terminal blocks, and wires routed through cable trays.

A hand-drawn sketch of the circuit diagram for the control circuit of the fan control.

The drawing shows many normally open and normally closed contacts, mostly drawn in series. They ultimately lead to the signal lights or relays.

First preparations for the announced ventilation control.

There isn’t much space on the mounting plate.

Components temporarily placed on a mounting plate intended for installation in a control cabinet.

First row (top): Starting from the left, there are three motor protection switches, each with auxiliary contacts, followed by a B6 circuit breaker and a power supply unit for 24VDC.

Second row: Three contactors, followed by two airflow monitors, and then four Zener barriers.

Third row: Terminal blocks arranged as 3-pole-terminal and 2-pole-terminal connectors.

The components are neatly organized but not yet secured, resting on the metallic surface of the mounting plate. Surrounding the plate are boxes containing additional parts.
