Hantle 1700W Bill Dispenser: Serial Number and... | terminalfaults.org

Technical Background:

The Hantle 1700W utilizes a 24V DC logic system to control the bill dispensing mechanism, including solenoids and optical sensors. Serial number verification relies on optical character recognition (OCR) and data transmission via serial communication (RS-232 or USB) to a central processing unit. Issues can arise from voltage fluctuations affecting solenoid timing, sensor degradation due to environmental factors (-40C temperature extremes), or communication errors. Electromagnetic interference (EMI) can also corrupt data transmission from the OCR unit.

Symptoms:

The Hantle 1700W dispenser is dispensing bills with incorrect serial numbers and exhibiting dispensing malfunctions.

Possible Causes:

Optical sensor malfunction due to dirt, debris, or degradation affecting accurate serial number reading.
Solenoid failure or timing issues caused by voltage fluctuations within the 24V DC power supply.
Communication errors between the OCR unit and the central processing unit due to loose or damaged cables, or EMI.
Bill path obstruction or misalignment, causing dispensing errors and incorrect bill selection.
Software or firmware bugs within the dispenser's control system, leading to incorrect serial number assignment or dispensing logic.
Degradation of bill transport rollers, leading to slippage and misfeeds.

Solution:

1

Visually inspect the bill path for any obstructions, such as jammed or torn bills. Remove any obstructions using appropriate tools.
2

Clean the optical sensors with a dry, lint-free cloth. Ensure the sensors are free from dust and debris.
3

Verify the 24V DC power supply voltage is within the specified range (typically +/- 5%). Use a multimeter to measure the voltage at the dispenser's power input.
4

Inspect the data cables connecting the OCR unit to the central processing unit for any damage or loose connections. Reseat the connectors to ensure a secure connection.
5

Cycle the power to the Hantle 1700W. This can sometimes resolve temporary software glitches.
6

Check the Hantle support website for any available firmware updates for the 1700W model. Follow the manufacturer's instructions to perform the update.
7

If available, perform a self-test or diagnostic routine on the dispenser via the kiosk's management interface. Note any error codes reported.

Safety Warning:

The Hantle 1700W operates on 24V DC. Although low voltage, always disconnect the power supply before performing any maintenance or troubleshooting. Environmental conditions, especially humidity, can increase the risk of electrical shock. Ensure the surrounding area is dry before working on the unit. High-voltage components may be present in the overall kiosk system powering the dispenser, follow Lockout/Tagout (LOTO) procedures where applicable. Ensure adequate ventilation to prevent overheating.

Prevention:

Regularly clean the bill path and optical sensors to prevent dust and debris buildup. Ensure proper cable strain relief to prevent damage to connectors. Periodically check the 24V DC power supply voltage to identify potential voltage fluctuations. Maintain a record of all maintenance activities.

Expert Tip:

Check the grounding connection of the Hantle 1700W. A poor ground can introduce noise into the system, leading to communication errors. Use a multimeter to verify a low resistance connection between the dispenser's chassis and the kiosk's grounding point. Additionally, use a regulated DC power supply for testing outside the kiosk system to isolate power-related issues.

Frequently Asked Questions

•What is the recommended cleaning frequency for the optical sensors?

The optical sensors should be cleaned at least monthly, or more frequently in dusty environments.

•Where can I find the latest firmware updates for the Hantle 1700W?

Firmware updates can be found on the Hantle website or through your authorized Hantle distributor.

•What tools are recommended for cleaning the bill path?

Use a soft brush, vacuum with a narrow nozzle, and a dry, lint-free cloth for cleaning the bill path. Avoid using liquids.
