Foot switches are switches that operate the circuit on and off by pressing or stepping with the foot and can also be used to control the level of output current. This type of switch is widely used in automatic airtight doors. The main reason for this is that they can be used in control circuits where hands cannot reach them in order to replace them for operational purposes, thus enabling, for example, medical staff entering and leaving automatic airtight doors in hospitals to enter and exit in a timely manner and improving efficiency. However, regardless of the type of switching equipment, there is a risk of failure, resulting in automatic airtight doors not opening and closing properly. This article introduces four common automatic airtight door faults caused by foot switch problems are how to repair and solve.
Fault one: the foot switch failure caused by automatic airtight door can not open.
Maintenance solutions: first check the circuit, see whether the motor and foot induction switch is connected to the power supply, if so, you need to confirm that the controller and switch there is no problem, there is also no problem, it is recommended to contact the doorway hundred percent to let the maintenance master to test the next.
Fault two: automatic airtight door open after power, foot pedal automatically close, control chaos occurs.
Repair solutions: this situation, the automatic airtight door controller should be adjusted to the opposite direction can be.
Fault three: automatic airtight door foot switch failure.
Maintenance solution: first check whether it is because of wiring problems, such as wiring problems can be reconnected. In the check whether the foot switch is damaged, replace the repair can be.、
Fault four: After the automatic airtight door is energised, the door is kept open and the foot switch is not closed.
Maintenance solutions:
1. Check whether the red indicator light of the safety light receiving box is always on, if the green indicator light is flashing, the two black plug wires on the safety light receiving box need to be adjusted to the position. If the red light is always on, adjust the controller labeled position, if the current white switch in the "R" position, you need to adjust to the "L" position, restart the power switch to test whether normal.
2. After restarting the power supply, if it still keeps the door open, check the controller, "DRP" shows a bright light state, it means there is a signal to open the door. Check whether the wiring of the foot switch on the right side of the track is correct. Plug and unplug the foot switch connection socket. (Possible poor contact). If this does not work replace the foot switch.
In addition to the above problems, in everyday use it is important to note the load rating of the foot switch, depending on the nature of the load and the current value. Please be aware of short circuits and disconnections in the internal wiring when handling and moving. Please pay attention to the protection level of the foot switch when using it in places where there is a lot of water, oil, dust, etc. Please be careful when using foot switches as heavy pressure and impact are direct causes of damage.
