Safety distance
The basic principle is that dangerous machine movements should be stopped before a person reaches the
dangerous area, which should be at least 850 mm from the light beams. When determining the correct safety
distance the stopping time of the machine and the risk level must be taken into account (see also EN 13855).
Contact ABB/Jokab Safety for further information.
Accessories and mounting
The Spot light beam can be mounted using a variety of brackets, posts and mirrors. Refer to the product list at
www.abb.com/lowvoltage for further information.
NB: Every mirror reduces the sensing distance of the beam by approx. 20%.
Mounting height
When using two or three light beams, the mounting heights specified in
Table 1
should be used.
