G-13 Coin Acceptance Accuracy Test Procedure - Solar Faults | terminalfaults.org

Technical Background:

The G-13 likely utilizes inductive sensors to identify coins based on their metallic composition and diameter. A 24V DC signal activates solenoids to direct accepted coins to the cash box. The validator's internal CPU analyzes sensor data to determine coin validity. Environmental factors such as extreme temperature (-40C) can alter sensor readings and component performance. Coin validation relies on tightly calibrated inductance thresholds and solenoid actuation timing.

Symptoms:

Inaccurate coin recognition and acceptance by the G-13 coin mechanism. Coins of valid denomination are rejected or misidentified. Possible jamming or delayed acceptance times are also noted.

Possible Causes:

Accumulation of dirt, debris, or foreign objects on coin pathway or sensors.
Voltage fluctuations in the 24V DC power supply affecting sensor accuracy and solenoid performance.
Sensor drift due to thermal stress or component aging, leading to incorrect coin identification.
Mechanical wear in the coin diverter solenoid mechanism, causing delayed or incorrect routing of coins.
Corrosion or oxidation on sensor contacts, resulting in signal degradation.
Software or firmware errors within the coin validator's CPU causing misinterpretation of sensor data.

Solution:

1

Power cycle the G-13 coin mechanism and the host kiosk system.
2

Inspect the coin entry slot and coin path for any visible obstructions. Use compressed air to dislodge loose debris.
3

Clean the coin sensors using a dry, lint-free cloth. Avoid using liquids.
4

Verify the 24V DC power supply output voltage is within the manufacturer's specified tolerance using a multimeter.
5

Check the wiring harness connecting the coin mechanism to the kiosk system for loose connections or damaged wires.
6

Refer to the G-13 service manual (if available) for diagnostic codes and troubleshooting procedures.
7

If the problem persists, consider contacting a qualified technician for further diagnosis and repair. Replacement of sensors or the entire unit may be required.

Safety Warning:

The G-13 coin mechanism operates on 24V DC. While this voltage is not lethal, improper handling can result in electrical shock or damage to the equipment. Always disconnect the power supply before performing any maintenance or cleaning procedures. Follow Lockout/Tagout (LOTO) procedures to ensure the kiosk system remains de-energized during maintenance.

Prevention:

Implement a regular cleaning schedule for the coin mechanism. Use compressed air to remove dust and debris from the coin path and sensors. Periodically inspect wiring and connections for damage or looseness. Ensure the kiosk environment is within the operating temperature range specified by the manufacturer.

Expert Tip:

If coin acceptance accuracy degrades over time, try running the coin validator's self-calibration routine (if available). Consult the G-13 service manual for instructions. Sometimes, a slight adjustment to the coin sensor sensitivity can improve performance. Document all adjustments made.

Frequently Asked Questions

•Does the G-13 have a diagnostic mode?

Consult the G-13 service manual for instructions on entering and using the diagnostic mode. This mode may provide error codes or sensor readings.

•What is the recommended cleaning schedule for the G-13?

The cleaning schedule depends on the environment. In high-traffic locations, clean the coin mechanism weekly. In cleaner environments, monthly cleaning may suffice.

•Where can I find a replacement G-13 coin mechanism?

Contact the original kiosk manufacturer or search online for suppliers of coin mechanisms. Ensure the replacement unit is compatible with your kiosk system.
