G-13 Coin Stacker Sensor Fault Diagnostic and Procedure... | terminalfaults.org

Technical Background:

Coin stacker sensors typically use infrared (IR) or optical beam break sensors operating at 5V DC or 12V DC. Sensor signal integrity depends on a clean 0V ground reference. Contamination, such as dust or debris, can attenuate the signal. Corrosion on sensor connectors can increase resistance, leading to voltage drops below the sensor's operating threshold. Ambient light interference can affect optical sensors.

Symptoms:

Coin stacker reports incorrect counts or no count at all. System logs may indicate sensor timeout or invalid data.

Possible Causes:

Sensor surface contamination (dust, debris) blocking IR or optical beam.
Sensor connector corrosion or loose connection causing signal degradation.
Sensor power supply failure (5V or 12V DC rail issue on the mainboard).
Mechanical obstruction in the coin path blocking sensor detection.
Failed sensor due to component aging or ESD (Electrostatic Discharge).
Wiring harness damage (cut, crimped, or frayed wires) interrupting signal transmission.

Solution:

1

Power cycle the G-13 kiosk. A soft reset may clear temporary errors.
2

Inspect the coin stacker area visually for any obvious obstructions or debris.
3

Use compressed air to carefully clean the sensor surface and surrounding area. Do not use liquids.
4

Check the sensor connector for proper seating. Gently push the connector to ensure a secure connection.
5

Review kiosk system logs for sensor-specific error codes. Consult the G-13 service manual for error code definitions.
6

Inspect the wiring harness leading to the sensor for any visible damage.
7

If the problem persists, consult a qualified technician for component-level diagnostics and sensor replacement.

Safety Warning:

Disconnect power from the kiosk before performing any inspection or cleaning. Ensure the area is dry. Although the coin stacker is low voltage, the power supply contains potentially lethal voltages. Do not attempt to repair the power supply without proper training and equipment. Follow proper electrostatic discharge (ESD) precautions when handling electronic components. Use a grounded wrist strap.

Prevention:

Regularly inspect and clean the coin stacker area (every 3 months). Schedule preventative maintenance to check sensor connections and wiring. Implement a filter system to minimize dust accumulation.

Expert Tip:

Use a digital multimeter to check the sensor's power supply voltage (typically 5V or 12V DC) at the connector. A voltage reading outside the specified range indicates a power supply issue. Note the ambient temperature if outside -20C to +50C.
