Enclosure type 1.
Align the sender (GRS18) with the receiver (GRE18). Select the position so that the red
emitted light beam hits the receiver. Tip: Use white paper or a reflector as an alignment
aid. The sender must have a clear view of the receiver, with no object in the path of
the beam [see figure 4]. You must ensure that the optical openings (front screen) of the
sensors are completely clear.
Figure 4: Alignment
Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation:
Operating reserve increased; counterclockwise rotation: Operating reserve reduced. We
recommend setting the potentiometer to "Maximum".
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check the
function. If the switching output fails to behave in accordance with Graphic C, check the
application conditions. See section Error analysis.
