Maintenance and care
Do not make any repairs to the device!
The SafeZone Mini does not contain any repairable components. For this reason do not open the SafeZone Mini
components and only replace the parts that are described in the following chapters as replaceable.
Switch the entire machine/system off line!
The system could inadvertently start up while you are replacing the optics cover. As a matter of principle, always isolate
the machine from the power supply during all work on the machine and safety laser scanner.
Cleaning optics cover The SafeZone Mini safety laser scanner is largely maintenance-free. The optics cover on the safety laser scanner should
however be cleaned regularly and if it is contaminated.
 Do not use aggressive cleaning agents.
 Do not use abrasive cleaning agents.
Note Static charges cause dust particles to be attracted to the optics cover. You can diminish this effect by using the anti-static
plastic and the lens cloth.
How to clean the optics cover:
 Use a clean and soft brush to remove dust from the optics cover.
 Moisten the optics cloth with the anti-static plastic cleaner and wipe off the window for light output on the optics
cover with the cloth.
Replacing the optics cover
Perform an optics cover calibration with the aid of the SCD software after the replacement of the optics
cover!
The level of contamination is measured continuously during the operation of the SafeZone Mini. For this purpose the
optics cover calibration must first be performed; this then serves as a reference for the contamination measurement
(status = not contaminated).
The optics cover calibration is only allowed to be performed with a new optics cover! The new optics cover must be free of
contamination at the time of the optics cover calibration. The optics cover calibration should be performed at room
temperature [10°…30°C (50°…86° F)]!
If the optics cover is scratched or damaged, you must replace the optics cover. Order the replacement optics cover from
Rockwell Automation (see Chapter 13,“Accessories/spare parts” on page 65).
Notes • The optics cover on the SafeZone Mini is an optical part that must not be soiled or scratched on replacement.
• The optics cover is only allowed to be replaced by qualified safety personnel in a dust and dirt-free environment.
• Never replace the optics cover during ongoing operation, as internal parts may be irreparably damaged in certain
circumstances and dust particles may enter the device.
• It is imperative that you avoid contamination of the inside, e.g. with fingerprints.
• Do not use any additional sealant for sealing the optics cover, e.g. silicon, as these substances may affect the optics.
• Use a torque wrench (universal joint) with 2.5 mm hex socket bit.
• Mount the optics cover as per the following instructions to ensure that the housing is sealed to IP 65.
