Problem Summary:Troubleshooting card issuance failures using the built-in card issuer in a three-roller turnstile access control system.
- Unable to install card issuance software:
- Problem: After installing the card issuance software on a Win10 computer, it cannot be opened. Clicking on the login button causes it to crash.
- Solution: Checked if the Microsoft runtime component library was installed completely. .NET Framework 3.5 was installed, but the issue persisted.
- Root Cause: Found that the customer’s computer had many databases and different access control software installed, causing software conflicts.
- Alternative Solution: Replaced the computer and reinstalled the card issuance software.
- Three roller gate issued card swipe rejected:
- Problem: The card reader successfully writes access permissions to the card, but when swiped, it is rejected.
- Solution: Modify the card reader format using the software. Please follow the instructions in the image and perform the operation once.
- Root Cause: The card reader encoding format was incorrect.
Simply check both options and click the Settings button.（In the system language non-Chinese computer to open the software may be garbled, but does not affect the operation.）
If you find a three roller gate entrance, swipe your card to get through. Exit swipe card shows access denied, please check whether all the three roller gate lines are connected normally. (We found that the customer’s three roller gate reader cable is not linked.)
Issue 1: Card Issuance Software Installation Failure When attempting to install the card issuance software on a Windows 10 system, the application would unexpectedly close upon login. Initial troubleshooting focused on ensuring that the required .NET Framework 3.5 was installed correctly. However, the underlying issue was identified as software conflicts arising from the presence of multiple databases and other access control software on the same machine. As a resolution, it was determined that reinstalling the software on a clean system would be the most effective approach.
Issue 2: Card Reader Rejection Even though the card reader was successfully programming access permissions onto the cards, the gate system would consistently reject these cards. Upon further investigation, it was discovered that the card reader’s encoding format was configured incorrectly. To rectify this, the software was used to modify the card reader settings according to the provided guidelines.
Troubleshooting a Dropped Turnstile Arm That Won’t Raise
Problem: A three-roller turnstile, which should normally raise its arm when powered and lower it automatically when power is off, is failing to raise its arm.
Cause: The turnstile’s electromagnet is loose. Refer to the provided video for specific instructions.
Solution:
- Power on the turnstile.
- Loosen the two screws securing the electromagnet.
- Gently pull up the arm and allow the electromagnet to attract it.
- Tighten the screws to secure the electromagnet.
The arm should now raise when powered and lower when powered off.
Technical Explanation:
A three-roller turnstile is a type of access control gate that uses three rotating arms to control pedestrian traffic. The electromagnet is a key component that is responsible for raising and lowering the arm. When the electromagnet is energized, it creates a magnetic field that attracts a metal plate on the arm, causing it to rise.
If the electromagnet is loose, it may not be able to generate enough magnetic force to lift the arm. By following the steps outlined above, the electromagnet can be tightened to ensure a secure connection and proper operation.
