Protection height≥ machine slide stroke + adjustment amount
WARNING
Safety distance is one of the necessary conditions to ensure that the photoelectric protection device realizes the
protection function, the safety distance must be calculated correctly, and the safety distance must be ensured during
installation!
1、the determination of height position
The height position refers to the position of the light curtain of the photoelectric protection device relative to the
upper and lower die ports of the machine tool, that is, under the premise of ensuring a safe distance, the lowest beam
of light of the photoelectric protection device shall not be higher than the lower edge of the lower die mouth, and the
top beam of light shall not be lower than the upper edge of the upper die port.
This involves the selection of the protection height of the photoelectric protection device

Protection height:H
A. The height position is one of the necessary conditions to ensure that the photoelectric protection device realizes
the protection function, and the height position must be ensured correctly during installation.
B. If the mold is replaced during use, the safety distance and height position must be readjusted according to the
above two requirements.
WARNING
2. Setting of auxiliary protective measures
When the horizontal distance between the light cuain plane of the photoelectric protection device and the front end
of the mold base exceeds 400mm, auxilia photoelectric or protective fences should be installed to prevent the
operator's body from entering the inside of the light cuain plane. When it is less than 400mm, safety measures such
as auxilia photoelectric or protective fence can also be taken.
