Installation position refers to the relative position of the light curtain to upper and lower die orifice of machine tool. That is to say the lowermost light beam should not be higher than the lower edge of the lower die orifice. The uppermost light beam should not be lower than the upper edge of the upper die orifice. This involves the choice of protective height of safety light curtains.
Protective height The slider of machine tool+ regulating quantity.
Tips from ESPE:
b. If there is machine tool sliding phenomenon, must inspect and adjust the machine tool immediately. Otherwise, even the safety light curtain is correctly installed, safety can not be ensured. Safety light curtain can only control the electrical control part but can not avoid machine tool sliding and breakage,etc.
c. When the protection distance is more than 400 mm, other auxiliary measures must be taken.
d. Height position is the necessary condition that ensures the safety light curtain realizes its safety function. The correct height position
must be ensured while under installation.
a.The installation of external controllers
Choose the proper installation position according to the controllers shape and size. Normally they should be installed at the position which is easy to be noticed.
At meantime, take crash avoidance, easy operation and maintenance into consideration.
b. The installation of Internal controller
Directly clamp and install the controller on the 35mm electrical guide. Protective cover should be installed addtionally while it is installed outside the control box.
c. The installation of simple type controllers.
Simple type controllers are almost same with external controllers while the controller is more simple.
The installation method of blendboard mounting bracket :The installation method that directly fixes the emitter and receiver on the machine tool, normally applicable to straight side press with frame structure.
Install the emitter and receiver on the machine tool by steel tube bracket, normally applicable to open side press and four column hydraulic press.
The installation method of blendboard mounting bracket :The installation method that directly fixes the emitter and receiver on the machine tool, normally appplicable to straight side press with frame structure.
Tips from ESPE:
a. Make the top and bottom of the emiter and receiver parallel . The light emitting surface and the light receiving surface should be vertical to the plane and aligned.
b.The light receiver must be installed at the side close to the controller.
