The safety light curtains ILVT designed especially for their use as protection devices at hazardous sites and areas, as well as pedestrian access. By the use of the blanking features, moving or stationary objects can be blanked.

• raw material converting presses operated in the metal, wood, plastic, rubber, leather, glass industry
• filter presses
• folding and bending machines
• die-casting machines
• processing lines and welding presses
• insertion machine
• robots
• palletizers

The transmitter generates infra-red light beams flashing at high speed in synchronous action. The parallel light beams with a spacing of 7,5mm or 14,3mm are monitored by miocro-controllers. The receiver evaluated the arriving beams in synchronous action to the transmitter.
Due to the closeness of the beams, a resolution of 14 mm / 30 mm is achieved. If an obstacle is placed into the protective field, i.e. at least iner lieght beam is interrupted, the hazardous movement of the machine is stopped, i.e. a new start is not possible.

Programmer for activation of blanking functions. Simple programming by 4 dip switches, authorization by key-switch.

BPSG: For blanking light barriers with power supply and restrictedly guided relais with potential-free outputs.
BLPG: Programmer for blanking light barriers. Unit may be removed after completed programming. The program will remain permanently in the light curtain and will remain unaffected even in case of a voltage drop.
