ICT L70 Bill Acceptor: Best Practices for Storage -... | terminalfaults.org

Technical Background:

The ICT L70 incorporates a 24V DC power system for solenoid activation and optical sensor operation. Extended storage can impact sensor calibration due to dust accumulation or humidity-induced component drift. Polymer bill compatibility relies on calibrated optical transmittance readings. Environmental factors impact optical sensor performance.

Symptoms:

N/A. Preventative storage guidelines requested. Device operational.

Possible Causes:

Dust accumulation on optical sensors during storage, altering calibration.
High humidity leading to corrosion on electrical contacts and sensor drift.
Extreme temperature variations causing component stress and potential failure.
Improper packaging exposing the unit to physical damage during storage.
ESD (Electrostatic Discharge) damage during handling prior to storage.
Contamination of the bill path from residual bill dust degrading roller adhesion.

Solution:

1

Disconnect the L70 from the power source. Confirm voltage is absent using a calibrated multimeter.
2

Clean the exterior of the unit with a dry, lint-free cloth to remove any surface dust or debris.
3

Inspect the bill path for any obstructions or debris. Use compressed air to gently remove any loose particles. Do not use liquids.
4

Place the unit in an anti-static bag to protect against ESD during storage. Ground yourself before handling the unit.
5

Store the unit in a climate-controlled environment, ideally between 15°C and 25°C with relative humidity between 30% and 50%.
6

Use a desiccant pack within the anti-static bag to absorb any residual moisture.
7

Mark the storage date clearly on the packaging for inventory control and to track storage duration.

Safety Warning:

Disconnect the ICT L70 from its 24V DC power supply prior to any handling or storage procedures. Ensure the power source is de-energized prior to disconnection. Electrical shock hazard exists if the unit is connected to power during handling. Follow established Lockout/Tagout (LOTO) procedures during disconnection.

Prevention:

Regularly inspect the storage environment for temperature and humidity fluctuations. Replace desiccant packs periodically. Rotate stock to prevent prolonged storage. Implement a first-in, first-out (FIFO) system.

Expert Tip:

Record the initial calibration settings of the optical sensors before storage, if possible, using the ICT configuration software. This will facilitate quicker recalibration upon re-deployment. Note any firmware versions.

Frequently Asked Questions

•What type of anti-static bag is recommended?

A static shielding bag conforming to MIL-PRF-81705 Type I or equivalent is recommended for optimal ESD protection during storage.

•How often should the desiccant pack be replaced?

Replace the desiccant pack every 3-6 months, or more frequently if the storage environment has high humidity. Inspect for saturation indicating replacement is needed.

•What are the signs of ESD damage to the ICT L70?

ESD damage can manifest as intermittent malfunctions, sensor errors, or complete failure of the unit. Visual inspection may reveal damaged components, but often ESD damage is not immediately apparent.
