Name
This menu is available only when a function has been enabled. Entering a name is
not required; the name is used only for internal unit functions. However, when
entering a name, select a name corresponding to the name of the relay output
previously selected.
To enter the name, use the same procedure described in PAR > Measurement Place
> Name.
Function
Assign functions to the selected relay by entering the Channel Number. Use the
ALT key to select from the following functions:
z
Disabled This function is not in use.
z Flow limit contact The relay will close if the flow exceeds a designated
threshold and open if the flow falls below a second designated threshold.
z
Velocity limit contact The relay will close if velocity exceeds a designated
threshold and open if velocity falls below a second designated threshold.
z
Level limit contact The relay will close if the depth level exceeds a
designated threshold and open if the depth level falls below a second
designated threshold.
The following functions need to be set only one time:
Total positive impulses – the relay will output volume-proportional
impulses if the flow occurs in a positive direction. Weighting and
impulse duration are programmable.
Total negative impulses – the relay will output volume-proportional
impulses if the flow occurs in a negative direction (backwater].
Weighting and impulse duration are programmable.
Error messages – the relay will close when error messages occur,
such as sensor errors, cable breaks, power failures, or processor
failures.
