Safe and effective cleaning guidelines for Scheidt & Bachmann Entra.Station bill validators in unattended kiosks. Maintain reliability and prevent jams.
Isopropyl alcohol, 90% or higher, is recommended. Ensure complete evaporation before use.
The frequency depends on the environment and usage, but weekly or bi-weekly cleaning is generally recommended.
Refer to the Scheidt & Bachmann Entra.Station service manual for specific error code definitions related to sensor malfunctions.
The Entra.Station bill validator uses optical and magnetic sensors to authenticate bills. Dust, debris, and residue accumulation on these sensors and the bill transport mechanism can attenuate or distort signals, leading to misreads and jams. Solenoids control the bill path. Insufficient voltage or mechanical obstruction affects performance.
High voltage present within the Entra.Station enclosure. Lockout/Tagout (LOTO) procedures MUST be followed during any maintenance or cleaning. Improper grounding can cause electric shock. Ensure adequate ventilation when using isopropyl alcohol. Avoid contact with eyes and skin. Dispose of used cloths properly.
Implement a regular cleaning schedule (e.g., weekly or bi-weekly) based on environmental conditions and usage.,Use a dedicated vacuum cleaner with a HEPA filter to remove dust from the kiosk interior.,Place a debris mat near the kiosk to minimize dirt tracking.,Train personnel on proper bill validator cleaning procedures.,Periodically inspect and replace worn transport rollers and belts.,Ensure adequate ventilation to minimize dust accumulation.
Use a borescope or inspection camera to visually inspect hard-to-reach areas within the bill validator. This can help identify hidden obstructions or sensor contamination. Check the bill validator's event log for error codes that may indicate specific sensor failures or voltage drops.
