Trip Type: Determines the control logic of the relay or NPN output (see chart
on next page for more information).
Type 0 or “Near” activates the output whenever the target is closer than the
trip distance (trip window is not used with type 0).
Type 1 or “Exclusive” activates the output whenever the target is closer than the
trip distance OR farther than the trip distance + trip window.
Type 2 or “Hysteresis Near” activates the output whenever the target moves
closer than the trip distance. Once active, the output will remain active until the
target moves beyond the trip distance + trip window, at which point the output
deactivates. Once deactivated, the output will remain deactivated until the target
once again moves closer than the trip distance.
Type 3 or “Far” activates the output whenever the target moves beyond the trip
distance (trip window is not used with type 3).
Type 4 or “Inclusive” activates the output whenever the target is further than the
trip distance and closer than the trip distance + trip window.
• Programming Relay and NPN Trip Outputs
Relay or NPN trip outputs can be programmed to operate using one of six
control logic functions, providing a high degree of flexibility for process
monitoring and control. Each control logic function, or “trip type”, is described
in the Trip Type section below.
Trip Distance: Sets the distance to the trip position nearest the sensor face.
Trip Window: Sets the distance, beginning from the trip distance, to the farthest
trip position.
