When commissioning, protect the device from moisture and contamination.
These operating instructions contain information required during the life cycle of
the sensor.
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
The WLD26 is an opto-electronic photoelectric retro-reflective sensor (referred to as
