The DORS 600/620 is a banknote counter designed for efficient and reliable counting of banknotes, with additional features for authenticity control in the DORS 620 model. Manufactured by DORS Industries (China) LTD., this device is intended for professional use where accurate banknote counting and, in some models, counterfeit detection are critical.
Function Description
The primary function of the DORS 600 is to count new and worn-out banknotes. It offers the capability to reject off-grade banknotes and to form batches of a required number of banknotes. This makes it suitable for various environments, from retail to banking, where high-volume cash handling is common.
The DORS 620 model extends these capabilities by incorporating advanced authenticity control features. It can detect counterfeit banknotes by checking for the lack of banknote paper background luminescence under UV light. Additionally, it controls the presence of Anti-Stokes luminescence, a feature applicable to a limited number of currencies, providing an extra layer of security against sophisticated counterfeits.
The counter operates in both manual and automatic modes. In automatic mode, counting begins as soon as banknotes are placed in the hopper. In manual mode, the user initiates counting by pressing the START/CLR key. The device can be set to count a specific batch size, stopping automatically once the desired number of banknotes is reached or the stacker capacity is full.

Usage Features
The DORS 600/620 features an intuitive control panel with batch keys (1-0), ADD, MAN, and START/CLR keys. The DORS 620 model adds UV and AS keys for authenticity control.
- Batch Setting: Users can set a desired batch size from 1 to 999 using the batch keys. The device stops counting and signals when the batch is complete.
- Addition Mode (ADD): When activated, the counter adds the number of newly counted banknotes to the previously counted total, indicated by a red light on the control panel.
- Manual/Automatic Mode (MAN): The MAN key toggles between manual and automatic counting modes. In manual mode, counting requires pressing START/CLR.
- UV Authentication (DORS 620 only): The UV key activates/deactivates UV authentication and allows selection of UV control levels (UL 1, UL 2, UL 3, UL OFF). UL 1 is recommended for Euros and US dollars, while higher levels are for currencies with high UV luminosity. An "UL Err" message indicates a banknote with increased UV fluorescence.
- Anti-Stokes Authentication (AS, DORS 620 only): The AS key enables/disables Anti-Stokes authentication. An "AnS Err" message appears if a banknote without Anti-Stokes features is detected.
- Sound Signal: The sound signal can be switched on/off by pressing the '0' key for 3 seconds.
- Banknote Guides and Feeder Clearance: Adjustable guides and a screw for thickness adjustment (item 6 in Fig. 1) allow the user to optimize the counter for different banknote sizes and conditions, reducing errors like "Chn Err" (continuous chain) or "dbL Err" (doubled banknote).
- Error Codes: The device displays specific error codes (e.g., "Err Robu" for counting sensor error, "Stcr" for banknotes in stacker at startup, "HLF Err" for folded banknotes) to help users diagnose and resolve issues.
Maintenance Features
To ensure reliable and long-term operation, the DORS 600/620 requires regular maintenance and adherence to safety precautions.
- Daily Maintenance:
- Switch off the counter when not in use.
- Wipe external parts with a dry, lint-free tissue.
- Preventive Maintenance: A service engineer should perform partial disassembling and maintenance every 90 days. If the counter is used for more than one shift per day, maintenance should be more frequent.
- Safety Precautions:
- Avoid jewelry, loose clothing, and long hair near rotating parts.
- Prevent metal objects or liquids from entering the counter.
- Use a power outlet with protective earth contact (PE).
- Unplug the counter after use and keep the power switch in the OFF position when not in use for extended periods.
- Install on a flat, horizontal surface, away from extreme temperatures, humidity, direct sunlight, soot, or steam.
- Do not touch internal parts when connected to power supply.
- Do not disassemble the counter due to internal laser equipment (Class M1 invisible laser radiation).
- High dust content in the room can decrease operation quality.
- Troubleshooting: The manual provides a comprehensive list of error codes and troubleshooting steps for common issues, such as the counter failing to switch on or unusual noises during operation. For persistent problems or issues not covered by error codes, users are advised to consult the service division.
- Transportation and Storage: The counter should be stored and transported in its original manufacturer's package, in a heated and ventilated room, within specified temperature and humidity ranges, and in covered transport vehicles (automobile, railway, or pressurized air modules).
