Entra Station: Resolving Ticket Overflow Errors - Solar... | terminalfaults.org

Technical Background:

The ticket dispensing mechanism is controlled by a 24V DC solenoid. An optical sensor detects ticket presence. The system uses a serial communication protocol (likely RS-232 or RS-485) for communication between the sensor, solenoid driver, and main control board. Ticket jams can cause back EMF spikes exceeding component ratings (ESD risk).

Symptoms:

The Entra Station displays a "Ticket Overflow" error, even with valid tickets loaded within specified capacity.

Possible Causes:

Ticket sensor malfunction or obstruction (dust, debris).
Solenoid failure (coil open, shorted, or mechanically jammed).
Communication failure between the ticket sensor and the main control board (wiring, connector corrosion).
Ticket stock exceeding recommended specifications (thickness, material).
Firmware glitch in the main control board's ticket dispensing routine.
Power supply fluctuation affecting the 24V DC rail.

Solution:

1

Power cycle the Entra Station. Allow at least 60 seconds powered-off to ensure full discharge.
2

Visually inspect the ticket dispensing area for obstructions or damage. Use compressed air to remove loose debris. Do NOT use liquids.
3

Verify that the ticket stock meets the manufacturer's specifications regarding dimensions, thickness, and material.
4

Check the ticket sensor lens for smudges or dirt. Gently clean with a dry, lint-free cloth.
5

Examine all accessible wiring connections to the ticket sensor and solenoid driver for corrosion or loose connections.
6

Consult the Entra Station documentation for available diagnostic routines or error logs. Follow the documented procedure to access the system menu.
7

If available, update the firmware to the latest version provided by Entra. Follow all instructions provided by the manufacturer.

Safety Warning:

Disconnect power before performing any maintenance. High voltage components are present within the Entra Station. Risk of electrical shock. Do NOT bypass safety interlocks. Implement Lockout/Tagout (LOTO) procedures to isolate power sources during maintenance. Ensure adequate ventilation when using compressed air.

Prevention:

Regularly clean the ticket dispensing area with compressed air. Schedule routine inspections of wiring and connections. Use only approved ticket stock. Monitor and log dispensing errors to identify trends.

Expert Tip:

Many ticket sensors use infrared (IR) light. Use a smartphone camera (most phones filter visible light but not IR) to check if the IR LED is emitting when the system is powered on. If no light is visible via the camera, the sensor might be faulty or not powered.

Frequently Asked Questions

•What are the specifications of the ticket stock used in the Entra Station?

Refer to the Entra Station user manual or contact Entra support for the approved ticket stock specifications (dimensions, thickness, material).

•How do I access the diagnostic routines in the Entra Station?

Consult the Entra Station service manual for instructions on accessing the diagnostic menu. This typically involves a specific key combination or sequence entered through the keypad or touchscreen.

•What are the voltage and current ratings of the 24V DC power supply?

The power supply ratings are typically printed on the power supply label. Check for the 'VDC' (Volts DC) and 'A' (Amperes) markings. Replace only with an equivalent or higher rated power supply.
