Magner 150 Intermittent Power Loss Diagnostic Report -... | terminalfaults.org

Technical Background:

The Magner 150 operates on 24V DC. Power fluctuations can originate from the UPS, the Magner 150's internal power supply, or damaged cabling. Cold weather increases ESD risk. Polymer bill dust accumulation affects optical sensors causing error-state shutdowns. Marginal voltage from the UPS during peak load can trigger a power-down event. Solenoids require consistent voltage to operate correctly and can trigger faults when undervolted.

Symptoms:

Intermittent and unpredictable loss of power to the Magner 150 bill counter. The unit may power off spontaneously and/or fail to power on reliably.

Possible Causes:

UPS (Uninterruptible Power Supply) malfunction or insufficient capacity.
Degraded or damaged 24V DC power cable or connector.
Internal power supply failure within the Magner 150 unit.
Loose or corroded power connections.
Accumulation of dust or debris on internal sensors causing fault shutdowns.
ESD (Electrostatic Discharge) events damaging sensitive components.

Solution:

1

Verify the UPS is functioning correctly. Test with a known good device or replace the UPS batteries.
2

Inspect the 24V DC power cable for damage (cuts, kinks, or fraying). Replace if necessary.
3

Ensure the power cable is securely connected to both the Magner 150 and the UPS.
4

Clean the exterior of the Magner 150 with a dry, lint-free cloth to remove dust. Do not use liquids.
5

Cycle the power: Disconnect the power cable, wait 30 seconds, and reconnect.
6

If the problem persists, try a different power outlet or UPS to rule out environmental power issues.
7

Document all observations and tests performed for future reference.

Safety Warning:

The Magner 150 operates on 24V DC, which is generally considered low voltage and safe to handle. However, the UPS may contain high-voltage components. To ensure safe handling, always unplug the Magner 150 and UPS from the power outlet before inspecting cables or connections. Avoid contact with internal components of the UPS. Do not introduce liquids to the Magner 150; unplug before wiping with a dry cloth.

Prevention:

Regularly inspect the power cable for damage and ensure connections are secure. Clean the exterior of the unit with a dry, lint-free cloth to prevent dust buildup. Ensure adequate ventilation around the Magner 150 and UPS to prevent overheating. Implement a cable strain relief system to prevent damage to the power cable.

Expert Tip:

A failing UPS can sometimes output 'dirty' power with voltage spikes. Connect an oscilloscope to the UPS output to check for voltage irregularities. In retail environments with high foot traffic, consider using a more robust, industrial-grade UPS.

Frequently Asked Questions

•What is the rated power draw (in watts) of the Magner 150?

Consult the manufacturer's specifications for the exact power draw. Ensure the UPS has sufficient capacity (VA rating) to handle the load with a safety margin.

•What is the correct method for cleaning the Magner 150's internal sensors?

Do not attempt to clean internal sensors. This requires specialized tools and training. Contact a qualified technician.

•Where can I find replacement power cables for the Magner 150?

Contact the original vendor or search online for a compatible 24V DC power cable with the correct connector type. Ensure the replacement cable meets the original specifications.
