How to install QT4-18 automatic hydraulic block machine, and wires connection of PLC, solenoid valve, hydraulic station and sensors?

First of all, you should know automatic hydraulic block machine consisted by three parts:

a. host brick machine, it include all sensors and all sensors need to connected in a wires box, then one total cables connection with PLC controller

b. Hydraulic station. it include all solenoid valves, oil tubes. first you should follow all cylinders functions in host brick machine, then connect all oil tubes, then all solenoid valves function will confirm, then connection wires in solenoid valve.

then all solenoid valve wires become one cable, then connection with PLC controller

c. PLC controller. This parts will connection with electric power, all motors wires, all sensors wires, all solenoid valve wires and so on....

Notice:

1. If hydraulic station work, but machine not work, you should notice hydraulic station motor rotation direction. if motor rotation direction not correct, machine not work.

2. After install all wires, you should test all sensors work or not.

3. After check all, PLC choose manual model, then press all buttons one by one, if machine movements not same with button functions, just remember, then change wires.

Now let me show you all drawings for QT4-18 automatic hydraulic concrete block machine electric parts wires connection drawings

(If you understand this acritical, this method suitable for all automatic hydraulic block machines, include QT4-15, QT6-15, QT8-15, QT10-15...)

Photos explain you hydraulic oil tube connection location in hydraulic station

Video show you how to connection hydraulic station, sensors and PLC wires and tubes...
