SW-ABF Fully Automatic Packaging Machine Instructions Part III
If there is an alarm information in the picture, after processing the alarm content and without alarm information, click the "automatic" button, or select the external knob. At this time, the "automatic" button is displayed as bright green, prompting the switch to be completed, press the instrument start button, start the weighing system, click the screen or external "start" button, the device starts after about 6 seconds of initialization, alarm. Light accompanied by sound and light alarm, prompting the relevant personnel equipment to start, bagging swing arm to perform a lifting and falling action to return to the ready position, bagging car if not in the ready position will return to the ready position. After the initialization is completed, the start button on the screen lights up and the device enters normal working state.
Downtime operation
There are two ways to stop the operation. One is to stop the operation directly by clicking the "stop" button on the screen or the external stop button. The device immediately stops the action being executed according to the stop command, and each drive solenoid valve loses power.
This shutdown mode is mainly used in debugging process or abnormal production state.
Another way is to click on the screen or the external end button. At this time, the instrument stops weighing. The instrument that has finished weighing stops after performing a feeding action, and the equipment enters the shutdown state after all the feeding is completed. This function is mainly used to prevent material storage in weighing silos or transitional silos when the work is completed or off duty, resulting in material scattering due to the loss of support due to material gravity of the valve after the compressor shutdown pressure decreases.
