Magner 150: Counterfeit Detection Calibration... | terminalfaults.org

Technical Background:

The Magner 150 uses a combination of UV, MG (magnetic), IR (infrared), and dimensional sensors to verify currency. Sensor data is processed by a 24V DC logic circuit that compares readings against stored currency profiles. Calibration drifts can occur due to sensor aging, voltage fluctuations, or accumulation of dust/debris affecting sensor accuracy. ESD events can disrupt sensor readings, causing temporary or permanent calibration errors. Polymer bills, while durable, may have reflectance properties differing from paper currency, requiring specific calibration profiles.

Symptoms:

The Magner 150 consistently rejects valid currency or accepts counterfeit currency. Error messages related to sensor malfunction or calibration failure may be present. Performance degradation occurred during peak transaction times, correlating with possible ESD events (winter season).

Possible Causes:

Sensor contamination (dust, debris) affecting UV, MG, IR or dimensional readings.
Voltage fluctuations in the 24V DC power supply impacting sensor sensitivity.
ESD events causing temporary or permanent sensor calibration drift.
Outdated currency profiles in the system firmware.
Physical damage to sensors or sensor connectors.
Cable strain on sensor data cables (attenuation of signals).

Solution:

1

Safe Handling: Unplug the Magner 150 from its power source.
2

Inspect all sensor windows (UV, MG, IR, Dimensional) for visible dust or debris. Use a dry, lint-free cloth to gently clean the sensor surfaces.
3

Check the bill path for obstructions or accumulated debris. Clear any obstructions carefully.
4

Verify the input voltage to the Magner 150 is within the specified range (typically 24V DC) using a multimeter. A dedicated technician should perform this task.
5

Download and install the latest currency profiles and firmware from the Magner website using a USB drive. Follow the manufacturer's instructions carefully.
6

After updating the firmware, run the built-in calibration routine according to the Magner 150's user manual.
7

Test the counterfeit detection system with a known set of genuine and counterfeit bills to verify proper function. Re-calibrate if necessary.

Safety Warning:

High voltage is present in the Magner 150's internal power supply. Do not attempt to open the casing or perform internal repairs. Always unplug the device before cleaning or performing external maintenance. ESD can damage sensitive electronic components. Use Safe Handling procedures when working with the device.

Prevention:

Regularly clean the sensor windows and bill path with a dry, lint-free cloth.,Ensure the Magner 150 is placed in a location with stable power and minimal voltage fluctuations. Consider using a UPS (Uninterruptible Power Supply).,Implement ESD prevention measures, especially during dry winter months. This includes grounding straps for personnel and anti-static mats.,Periodically update currency profiles and firmware to maintain accuracy.,Ensure sensor data cables are not strained or pinched to maintain signal integrity.

Expert Tip:

If calibration fails repeatedly, try performing a 'factory reset' (refer to the Magner 150's user manual for the specific key combination). This will restore the system to its original settings and may resolve software-related calibration issues. Additionally, check the sensor data cable connections for corrosion or loose connections. Gently reseat the connectors to ensure a secure connection.

Frequently Asked Questions

•How often should the Magner 150 be calibrated?

Calibration frequency depends on usage and environmental conditions. At a minimum, calibrate quarterly, or more frequently in high-volume environments or after significant changes in humidity or temperature.

•What are the common signs of sensor failure in the Magner 150?

Common signs include consistently rejecting valid bills, accepting counterfeit bills, error messages related to specific sensors (UV, MG, IR), and significant calibration drift.

•Where can I find the latest firmware and currency profiles for the Magner 150?

The latest firmware and currency profiles can be downloaded from the official Magner website under the 'Support' or 'Downloads' section for the Magner 150 model.
