Trip Point Relay Control
The standard version of the LOE comes equipped with two solid-state relay
outputs (trip points), which can be programmed to perform one of several
logic func ons. In addi on, the LOE can be confi gured to ini ate immediate
email and/or text message alerts whenever either of the trip relays ac vates or
deac vates (see Immediate Website Alarms for more informa on).
NOTE: all Trip Point distance values are referenced from the face of the
sensor, regardless of the type of calculated reading being performed by the
sensor (level, volume, etc.). Refer to Trip Type chart for more informa on.
Trip Distance: sets the distance from the sensor face to the closest ac on point
(refer to Trip Type chart).
Trip Window: sets the distance, beginning from the Trip Distance loca on, to
the farthest ac on point (refer to Trip Type chart).
Trip Type: determines the type of opera onal logic performed by the trip point
relay (see descrip ons below and refer to the Trip Type chart).
Type 0 (Near): ac vates the relay when a target is closer than the Trip
Distance. The Trip Window is not used with Trip Type 0.
Type 1 (Exclusive): ac vates the relay when a target is closer than the Trip
Distance or farther than the Trip Distance + the Trip Window.
Type 2 (Hysteresis Near): When the target comes closer than the Trip
Distance, the relay will ac vate and remain on un l the target moves
beyond the Trip Distance + Trip Window. The relay will then deac vate and
remain off un l the target once again comes closer than the Trip Distance.
Used for emptying control or high alarm with hysteresis to prevent cha er.
Type 3 (Far): ac vates the relay when the target is beyond the Trip Distance.
The Trip Window is not used with Trip Type 3.
