Piros Thru-Beam Sensor LAD / LSD 201 04.07.2001 Details are subject to change without notice WG 510 Proxitron GmbH - Gärtnerstr. 10 - D-25335 Elmshorn - Tel. 04121/2621-0 - Fax. 04121/24404 - mail@proxitron.de L10E Adjusting Device LSD 201 The electronic adjusting device of Proxitron thru-beam sensor receivers serves for exact alignment to the transmitter. When the thrubeam sensor swivels, the green LEDs reach their max. indication in the centre of the optic axis. If no IR-radiation from the transmitter reaches the receiver, all three 3 mm LEDs remain dark. Already slight transmitter radiation incoming causes the receiver to switch. Normally-close: large LED (red) gives light. Normally-open: large LED (red) stops to give light. In the moment of switching the lower 3 mm LED starts blinking in red. Thus it indicates: there is radiation, but it is not sufficient for safe operation. With increasing radiation the lower LED changes from blinking in red to green light. Now safe operation is guaranteed. During alignment it should be tried to induce the second and third green LED to show green as well, in order to reach max. possible safety margin for operation.
