Brick machine door not work under manual condition

From today on, our company will explain the possible faults and troubleshooting methods of the discount qt4-15 fly ash brick machine door movement, which are divided into 5 sections. Cement brick machine price | free - burning brick machine price I. when the brick moulding machine is in production, the door of the brick machine cannot be moved manually. There are two reasons for this: 1-1 fault phenomenon: when pressing "SA3", the touch screen fault prompt shows the following: "the brick machine skip car is not in the rear limit or the limit switch is damaged, so the material door cannot be opened" Cause of failure: the brick skip car did not retreat to the rear limit or the proximity switch of the skip car's rear limit was too far away from the induction iron of the rear limit to be detected; The proximity switch doesn't work. (due to the interlock function of the equipment, the material door can only be opened when the skip car is in the rear limit) Elimination method: place the skip car in the rear limit. Make the proximity switch of the rear limit of the skip to sense the induction iron. The proximity switch indicator light is on, and the port on the touch screen is monitored, indicating that the proximity switch is in working state, and the material door can be moved. 1-2 the cause of the problem: skip place in the limit of customized qt10-15 brick moulding machine, the proximity switch position is no problem, check the port on the touch screen monitor, such as limit after skip proximity switch is not shown in working status, the "X3" input terminal of PLC when the light is not bright, probably skip limit the proximity switch is damaged or line break. After the input terminal of PLC "X3" damage, cause the proximity switch doesn't work. Exclusion method: in this case, regardless of whether the proximity switch indicator light can be on (when the indicator light is on, not necessarily in good condition), we should check whether the proximity switch is normal, then check whether the proximity switch line and PLC "X3" input terminal is normal, and then one by one according to the situation.
