Technical diagnostic and reset procedure for CPI MEI Cashflow 7000 coin counter. Covers potential causes, solutions, prevention and safety warnings.
The power supply should maintain voltage between 22.8V DC and 25.2V DC.
Use a dry, lint-free, anti-static cloth. Microfiber cloths are suitable.
Consult your organization's LOTO policy. It generally involves disconnecting power and physically locking the disconnect switch.
The MEI Cashflow 7000 coin counter relies on a combination of optical and inductive sensors to detect and categorize coins. These sensors generate voltage pulses interpreted by the internal microprocessor. Data transmission occurs via serial communication at a defined baud rate. Environmental factors (temperature extremes, humidity) can affect sensor accuracy and signal attenuation. ESD events can corrupt the memory storing coin count data.
Reported fault: Coin counter not accurately reflecting dispensed or received coin values.
High Voltage Hazard: The MEI Cashflow 7000 operates on 24V DC. Ensure the power is disconnected before performing any maintenance. Follow Lockout/Tagout (LOTO) procedures before servicing. Wear appropriate PPE (Personal Protective Equipment) such as safety glasses and gloves.
Regularly clean the coin path and optical sensors to prevent dust and debris accumulation.,Implement a scheduled maintenance program to inspect wiring harnesses and power connections.,Ensure the MEI Cashflow 7000 is installed in an environment with stable temperature and humidity levels.,Consider using a surge protector to protect against voltage fluctuations.
Check the coin discriminator settings within the host system. Incorrect discriminator settings can cause the coin counter to misinterpret coin values. Refer to the host system's documentation for details on how to access and adjust the coin discriminator settings.
