In the process of using the roof roll forming machine, the customer may encounter some problems. What should the customer do if he has a problem? Of course, contacting us to solve the problem is the best choice.
Recently, after received the color steel roof roll forming machine, the customer found that the machine can be used normally when it is manually operated, but it can’t work when it adopts the automatic mode.
To this end, we have sorted out some of the reasons that may cause this failure and their corresponding solutions.
1, The number of cuts is greater than or equal to the set number of sheets.
2, The number of sheets or the length is not set.
3. The automatic switch button is damaged.
4. The cutter does not rise and hits the travel switch. Or touch the travel switch, but there is no signal, the input 7 light does not light.
Approach:
Clear the current number of sheets {press the ALM button}.
When the automatic switch is in the open position, the IN terminal 2 light on the PLC is not lit {can be replaced by any brand LAY3 series knob}.
The travel switch is broken or the line from the travel switch to the electric box is broken.
If the above methods are invalid, please check: set the number and length, clear the current length, the cutter rises to the upper limit, the PLC input 7 lights up, turn on the automatic switch, check whether the line voltage is normal according to the drawing.
