1.1 General Data
Focus II light grids and curtains are active optoelectronic protective devices, AOPD, of type 4 by
EN 61496-1 and IEC 61496-2. They are intended to be used where it is essential to safeguard operators
of hazardous machinery, robots, or other automated systems where access to hazardous parts may be
gained.
Before using the Focus II units, all personnel responsible for installation and maintenance of this equipment
must ensure that they have read and understood the information contained in this manual. It is essential
that units are installed and used according to the instructions in this manual. All relevant standards and
regulations regarding the use of this type of equipment must also be strictly adhered to.
1.2 Maintenance
With the exception of checking alignment and cleaning the polycarbonate front covers that protects the
optics, no part of the safety barrier needs to be maintained or can be repaired by the user. The installation,
however, should regularly be checked and the results recorded. Should there be any errors, the barriers
must be sent to our service location together with an error description as well as estimated operating time.
NB! Damage or dirt on the cover does not compromise the safety level of the barriers but may cause
operational disturbance. Do not use woollen cloth, solvent or any other material when cleaning, which may
scratch or in some way damage the surface of the cover. Operational conditions decide how often the cover
needs to be cleaned.
ABB AB JOKAB SAFETY does not accept any liability for damage or injury due to incorrect use of the
protection barriers or associated components.
1.3 Important information
The Focus II system must be installed, configured, and incorporated into a machine control system by a
sufficiently trained and qualified person. An unqualified person may not be able to perform these operations
properly, which may cause a person to go undetected in to the hazardous area, resulting in serious injury.
When changes are made to each function using the selector switches, the administrator must manage the
detail of the changes and perform the changes. Accidental functional setting change may cause failure of
human body detection, resulting in a serious injury.
Do not drop the products. Dropping the products may lead to internal or external damage. Please return a
Focus II system that was dropped on the floor to your ABB AB JOKAB SAFETY service for inspection or
repair. Failure to do so may result in serious injury.
Make sure to test the operation of the Focus II system after installation to verify that the Focus II system
operates as intended. Make sure to stop the machine until the test is complete. Unintended function
settings may cause a person to go undetected, resulting in serious injury.
