• Separate the high voltage, signal, and supply cables.
• Make sure that the voltage and polarity of the power source is correct before connecting the HMI
panel to the power outlet.
• Peripheral equipment must be appropriate for the application and location.
1.6. During Use
• Keep the HMI panel clean.
• Emergency stop and other safety functions may not be controlled from the HMI panel.
• Do not use excessive force or sharp objects when operating the touch screen.
1.7. Service and Maintenance
• Only qualified personnel should carry out repairs.
• The agreed warranty applies.
• Before carrying out any cleaning or maintenance operations, disconnect the equipment from the
electrical supply.
• Clean the display and surrounding front cover with a soft cloth and mild detergent.
• The battery must be replaced by an authorized Beijer Electronics service center.
1.7.1. Cleaning the Display
We recommend using a dry, clean cloth to wipe off dust regularly. Use alcohol or ammonia-based
cleaning agent for cleaning only when necessary. When other solvents or cleaning agents are used,
be sure to follow manufacturers’ instructions. The agent should be applied to a clean cloth and
should not be sprayed directly onto the panel surface. After cleaning the agent should be removed.
Ammonia-based glass cleaners (typically 5-10% ammonia) or 75% alcohol can be used to clean the
surface of PCAP and resistive touch panels. When you clean the surface of your touch panel, please
follow these steps:
1. Apply cleaning agent (alcohol, bleach, or glass cleaner) to a clean cloth.
Make sure the cloth is well saturated.
2. Wipe the touch panel surface in a “Z” motion (see illustration below).
3. Dry the panel thoroughly with a dry cloth, removing as much of the cleaning solution as possible.
4. Do not mix bleach and ammonia because this will produce a dangerous chemical reaction.
5. Please do not spray cleaning solution directly onto the touch panel surface.
