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.
