MEI Cashflow 7000 Coin Payout Solenoid Replacement... | terminalfaults.org

Technical Background:

The coin payout solenoid is a 24V DC device responsible for actuating the coin dispensing mechanism. Its operation is controlled by the main system board, which sends a pulsed voltage signal. Degradation can occur due to mechanical wear, voltage spikes, or contamination. Solenoid resistance typically ranges from 20-50 ohms. Check for proper voltage and current flow to the solenoid connector.

Symptoms:

Failure of the coin payout mechanism. Coins are not dispensed upon request. Diagnostic logs may indicate a solenoid error or timeout.

Possible Causes:

Solenoid coil failure (open or short circuit).
Mechanical obstruction preventing solenoid movement.
Wiring harness damage or loose connections.
Failure of the 24V DC power supply.
Main system board malfunction.
Corrosion on solenoid contacts.

Solution:

1

Initiate Lockout/Tagout (LOTO) procedure to disconnect power from the kiosk.
2

Visually inspect the solenoid and surrounding area for damage or obstructions.
3

Using a digital multimeter, measure the resistance of the solenoid coil. Compare the reading to the manufacturer's specifications.
4

Check the wiring harness and connectors leading to the solenoid for continuity and shorts.
5

If the solenoid is suspected to be faulty, carefully disconnect it.
6

Install a new solenoid, ensuring proper alignment and secure connections.
7

Restore power to the kiosk and verify proper coin payout functionality.

Safety Warning:

High voltage is present within the kiosk. Always perform Lockout/Tagout (LOTO) procedures before servicing. Verify proper grounding to prevent electrical shock. Be cautious of sharp edges and moving parts.

Prevention:

Regularly inspect and clean the coin payout mechanism. Ensure proper ventilation to prevent overheating. Implement surge protection to mitigate voltage spikes. Check for loose connections quarterly.

Expert Tip:

Use a non-conductive tool to remove any debris or obstructions from the coin payout mechanism. Apply a small amount of silicone-based lubricant to the moving parts of the solenoid to reduce friction.
