G-13 Coin Stacker Maintenance Procedure - Solar Faults | terminalfaults.org

Technical Background:

The G-13 coin stacker employs a 24V DC motor to drive a series of belts and diverters that guide coins into designated storage tubes. Optical sensors detect coin presence and verify denomination. Debris accumulation can interfere with sensor accuracy and increase friction on moving parts, increasing motor current draw and potentially triggering fault states. Solenoid functionality may be impaired by particulate matter.

Symptoms:

Accumulation of debris within the coin stacker mechanism, leading to reduced coin acceptance rates and potential jamming. Audible grinding or unusual noises during coin processing. Visible build-up of residue on coin pathways.

Possible Causes:

Accumulation of dust, dirt, and other foreign materials within the coin pathway.
Buildup of residue from handling coins (e.g., oils, salts).
Wear and tear on the coin diverter mechanisms, leading to misalignment and jamming.
Failure of optical sensors due to obstruction or degradation.
Insufficient lubrication of moving parts within the stacker assembly.
Voltage fluctuations in the 24V DC power supply leading to reduced motor torque.

Solution:

1

Power down the G-13 unit and disconnect the power supply using Lockout/Tagout (LOTO) procedures.
2

Using a soft brush and vacuum cleaner with a small nozzle attachment, carefully remove loose debris from the exterior of the coin stacker assembly.
3

Apply compressed air to dislodge dust and dirt from internal components, directing the airflow strategically to avoid forcing debris further into the mechanism.
4

Dampen a lint-free cloth with isopropyl alcohol (90% or higher) and gently wipe down accessible coin pathways and sensor surfaces.
5

Inspect optical sensors for obstructions and clean them with a dry cotton swab.
6

Reconnect the power supply and power on the G-13 unit.
7

Perform a coin acceptance test to verify proper functionality and identify any remaining issues.

Safety Warning:

High voltage is present within the G-13 unit. Always follow Lockout/Tagout (LOTO) procedures before performing any maintenance or cleaning. Avoid using excessive amounts of liquid when cleaning to prevent electrical shorts. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, to avoid contact with debris and cleaning agents.

Prevention:

Establish a regular cleaning schedule for the coin stacker, based on usage and environmental conditions.,Implement a preventative maintenance program that includes periodic inspection and lubrication of moving parts.,Use only clean, dry coins in the G-13 unit.,Install a filter on the air intake vent to prevent dust and debris from entering the system.,Ensure proper ventilation around the G-13 unit to prevent overheating.

Expert Tip:

Check the coin diverter solenoids for smooth operation. A sticking solenoid can often be temporarily resolved by gently tapping the solenoid housing with the handle of a screwdriver. However, persistent solenoid issues indicate a need for replacement.

Frequently Asked Questions

•What type of lubricant is recommended for the G-13 coin stacker?

A light, non-conductive silicone-based lubricant is recommended for lubricating the moving parts of the coin stacker.

•How often should the coin stacker be cleaned?

The cleaning frequency depends on the usage and environmental conditions. A weekly or bi-weekly cleaning schedule is recommended for high-traffic locations.

•What are the common error codes associated with coin stacker malfunction?

Common error codes often relate to coin jams, sensor failures, or motor overcurrent. Consult the G-13's technical manual for a complete list of error codes and their corresponding troubleshooting steps.
