Maintenance

7 Maintenance

7.1 Maintenance during operation

The ICR890 System functions maintenance free. Regular maintenance is not required to

guarantee LED class 1M of the ICR890 System.

Note Do not open the ICD890 Camera or the ICI890 Illumination.

If the devices are opened, the manufacturer's warranty shall not apply.

Checking the incremental encoder

If an incremental encoder is used, the position of the friction wheel at the drive system

should be checked at regular intervals.

¾ Ensure that the incremental encoder has contact with the drive system and that the

friction wheel rotates without slipping.

7.2 Cleaning the ICR890 System

Recommendation In order to make use of the full optical reading capacity of the ICR890 System, the front

window should be checked regularly (e. g. weekly) for soiling. This is especially

recommended when operating the device in harsh conditions (dust, abrasion, humidity,

finger prints, etc.).

If possible, do not clean the deflection mirror due to its structure.

7.2.1 Cleaning the front window

LED radiation of class 1M (according to EN/IEC 60825-1)!

Incorrect use can result in hazardous radiation exposure and the LED class being

exceeded!

The accessible radiation of the ICI890 Illumination is not hazardous under reasonably

foreseeable conditions, provided that the beam width is not reduced by optical instruments,

e.g. magnifying glass, lenses, telescopes. Visual glare, loss of colour vision and eye injuries

cannot be ruled out.

The entire window surface is the LED radiation outlet opening.

¾ Do not look directly into the radiation source with optical instruments.

¾ Do not open the housing. (The illumination is not switched off if the housing is opened!)

¾ Always observe the latest valid version of laser protection regulations.

Damage to the front window!

Reduced reading capacity due to scratches or smears on the front window!

The front window of the illumination is made of glass. The opening for the camera within the

front window is made of special glass.

¾ Do not use aggressive cleaning agents.

¾ Do not use cleaning agents which cause increased abrasion (e. g. powder).

¾ Avoid cleaning motions at the front window which could cause scratches or abrasion.
