Configure the CPI MEI Cashflow 7000 bill validator to accept specific denominations. Includes troubleshooting and safety guidelines for commercial kiosks.
The MEI Cashflow 7000 uses optical sensors, inductive sensors, and dielectric constant measurements to identify bill denominations. Configuration data, including denomination acceptance settings, is stored in non-volatile memory. Incorrect configuration can stem from software glitches, corrupted data, or intentional modification via the programming interface. Communication occurs via a serial interface (RS-232 or USB) using a proprietary protocol. Voltage: 24V DC nominal. ESD sensitivity exists; observe proper handling procedures.
The CPI MEI Cashflow 7000 is not accepting all expected bill denominations, or is accepting incorrect denominations. This may manifest as rejected bills, or errors in transaction processing.
The MEI Cashflow 7000 operates on 24V DC. Disconnect power before performing any maintenance or troubleshooting. Be aware of potential pinch points when working around moving parts. Although ‘Lockout/Tagout (LOTO)’ is important, in a 'Commercial-Kiosk' environment, focus on 'Safe Handling'. Unplug the device before servicing. Keep the work area dry.
Regularly clean the bill path and optical sensors with a dry, lint-free cloth. Ensure proper cable strain relief to prevent damage to the communication interface. Periodically back up the validator's configuration settings. Monitor the validator's performance and log any errors or anomalies. Check for updates from the manufacturer.
If the validator consistently rejects a specific denomination, try cleaning the corresponding optical sensor with a cotton swab dampened with isopropyl alcohol (99%). Be sure to let the sensor dry completely before reassembling. A weak or degraded 24V power supply can cause intermittent errors; verify the power supply voltage under load.
