The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
Align the sensor with a suitable reflector. Select the position so that the red emitted
light beam hits the center of the reflector. The sensor must have a clear view of the
reflector, with no object in the path of the beam [see
optical openings of the sensor and reflector are completely clear.
Figure 3: Alignment
Adjust the distance between the photoelectric sensor and the reflector according to the
relevant diagram [see figure
After alignment, place a non-transparent object into the path of the beam. Check the
function as described in table
table 2, check the application conditions.
