Relay Settings
NOTE: All Trip Value and Trip Window settings must be entered using the
units being displayed. For example if the display is setup to read in gallons,
then the Trip Value and Trip Window parameters would be set in gallons.
TRIP V (Trip Value):
Sets the reading (in the units being displayed) for the first actuation point of the
relay.
TRIP W (Trip Window):
Sets the increase in the reading above the Trip Value to the secondary relay
actuation point.
Example: if the 2nd actuation point is desired at 100 inches of level, and the
Trip Value (the 1st actuation point) is set to 25 inches of level, then the Trip
Window would need to be set to 75 inches (25 + 75 = 100).
TRIP T (Trip Type):
Determines the operational logic performed by the relay (refer to the
descriptions and logic chart on following pages).
