Troubleshooting a 'Motor Overload' error on a Magner 150 bill counter. Includes diagnostics, solutions, and preventative maintenance for retail environments.
Compressed air and a soft brush are recommended. Avoid using liquids.
Cleaning frequency depends on usage, but a monthly cleaning is generally recommended for retail environments.
The motor lifespan varies based on usage and maintenance, but typically ranges from 3-5 years with proper care.
The Magner 150 relies on a 24V DC motor for bill/coin transport. An integrated thermal overload sensor protects the motor winding. The cooling fan maintains thermal regulation of the motor and associated driver circuitry. Accumulated dust or mechanical impedance in the fan can reduce cooling efficiency. DC motor driver circuits are susceptible to voltage spikes and ESD, potentially triggering overcurrent protection.
High voltage hazard exists within the Magner 150 power supply. Do not attempt internal repairs without proper training and equipment. Safe Handling: Always unplug the device from the power outlet before performing any maintenance. Avoid operating the device in humid environments to minimize ESD risk.
Regularly clean the cooling fan and bill/coin transport path with compressed air. Ensure the device is placed on a stable, dry surface. Implement a surge protector to mitigate voltage spikes. Use an anti-static wrist strap when performing maintenance, especially during dry winter months.
A temporary motor overload can sometimes be cleared by pressing and holding the 'Clear' button during the power-on sequence. This may reset the overload protection circuit. Document the ambient temperature; increased temperatures increase fan requirements.
