How Do You Troubleshoot Hermetic Doors?

If you own an automated hermetic door, the chances are it would at some point have an error and you need to know how best to handle it. Below are some of the errors you can expect and their possible remedies.

The door does not open or close

This will happen if there is no power supply to the door. So, make sure to check the power supply before thinking it is something else. Sometimes a lost connection can make the door not open.

The main fuse could also be blown. When this happens, the circuit is not complete and you cannot run the door too. As such, you need to replace the main fuse to complete the circuit and have the door working properly once again.

The functions set are not executed correctly

Sometimes you might set the functions on a hermetic door but you still find that the door is not working as you wanted. In such a case, it is possible the function selector is not set up correctly. Check to see if the correct settings have been used in the function selector.

You might also find that the safety mechanism is also active to prevent some functions from working. Check to see if there is anything wrong with the door first before resetting the hermetic door to work as you wanted.

The door movement is not linear

The chances are the door was not installed properly. This happens when the alignment is off or there is a component that is not set upright. You may have to consider calling experts on this one to pinpoint the possible problem affecting the door movement. Once it is sorted, you can have a hermetic door with a linear movement all the time.

The door can open but does not close

Yes, you can also experience such when running an automated hermetic door. When this happens, maybe the door is jammed. So, check its mechanism to see if there is one of the motors that are jammed or the pulleys too. This one will need more digging to establish the overall performance of the door. Sometimes regular maintenance should help avoid such inconveniences.

You can also check the settings from the function selector. There are times you may have selected the wrong mode. Such a mode may be designed to keep the hermetic door open always. Yes, that is possible too.

Also, check the opening devices and sensors to ensure they are working correctly. There are times they might be experiencing false detections. As such, they would think that someone is at the door thus the reason the sensors do not close the doors.

You can also get the same error whereby the door tends to open itself when no one is around. This is because the faulty opening devices keep sensing there is someone at the door when there is no one. If repairs are not possible, you may have to replace the door.

How Can You Maintain the Automatic Hermetic Sliding Door?

Maintenance is vital for ensuring the hermetic sliding door will work as expected. That is why you are advised to always follow the manufacturer’s maintenance schedule to keep the door working great as expected.

The first thing you have to do is get yourself qualified personnel that can do the job. The maintenance of hermetic doors does not require using quacks that might end up worsening the situation. It is possible to get professionals in such a field as there are companies that specialize in doing such work.

Routine cleaning does not need the use of other companies. That is something you can do in-house. This will include cleaning the hermetic door, the floor rails, and others. However, it is all the maintenance and repair work that has to be done by qualified personnel.

So, what are some of the maintenance work that has to be done?

The first thing would be to disconnect the power to the hermetic door. Once you have done this, proceed to check the following.

  • Look at the screws ensuring that they are tight. You may have to tighten some of them if they are loose.
  • Look at the overall cleanliness of the rail and carriage. You need a hermetic door that can open with ease all the time.
  • Since we are considering a sliding door, look at the belt tension. If it seems to lose, go ahead and tighten it too.
  • You should still look at the wear of the belt. There is no point in continuing to use a worn belt that might snap any moment. Look at the carriage wheels too. If they are too worn out, they should be replaced.
  • Always check the overall fitting of the hermetic door on the carriages.

Once you are done with the checks mentioned above, you can proceed to do other checks. This time the door needs to be powered. So, connect it to the power supply and conduct the following checks on it.

  • Check to see if the control devices are working correctly. Also, check to see if the safety measures can kick in whenever necessary.
  • Also, check the detection sensors. Make sure they are in proper working condition and are compliant with the various standards depending on the location.
  • In case there is a device that works on a battery, check them too. If the battery is not in good condition, proceed to replace it too.

All the checks mentioned above have to be done every 6 months or after every 20,000 cycles. Whichever comes first.

All the maintenance that is performed on the hermetic door should be noted in a proof book. This ensures that the next maintenance will be easy as you know what was checked, replaced, and repaired.

If you can keep up with the maintenance schedules, then your hermetic door will always work great as you want.
