3 Sensing range setting
Sensor not able to be set: The sensor has been adjusted to maximum sensing range by the
factory and is ready for operation. The sensor may have been preset by the factory to a
shorter sensing range on a 90% (white) remission target. This is possible in 25 mm incre‐
ments starting at 50 mm and indicated by a Dxx suffix on the Model Number. For example:
•
ZTE18-xxxxxxD02 has preset sensing range of 50 mm on a 90% remission target
• ZTE18-xxxxxxD04 has preset sensing range of 100 mm on a 90% remission target
• ZTE18-xxxxxxD07 has preset sensing range of 175 mm on a 90% remission target
The Dxx is omitted when the sensor has been adjusted to maximum sensing range.
4 Operation with marginal light reception
The sensor will provide a pre-failure notification by flashing the orange LED indicator when
operating with marginal light reception. This may be the result of incorrect alignment, cont‐
aminated optical surface(s), and/or insufficient light remission from the target. The sensor
