Level Controller
4-4
Set Controller Height
Determining the controller height varies according to the installation
type and controller location (see Figure 3-3). Note that the controller
height units are determined by the units selected for the level units.
Controller Height
Open Tank, controller above tank bottom A
Open Tank, controller below tank bottom –B
Open Tank with Bubbler C
Closed Tank w/dry leg, controller above tank bottom A
Closed Tank w/dry leg, controller below tank bottom –B
Closed tank w/wet leg, controller above tank bottom E + D
Closed tank w/wet leg, controller below tank bottom M – N
Factory Default: 0
Valid Range: –300 to 300 meters
Additional Options
The following options are not required for Level Controller operation.
Set Damping The Level Controller has electronic damping that can change the
response time of the level measurement to smooth the level reading
when there are rapid input variations.
Level Damping High damping values filter out process noise, but response time is
increased. Low damping values decrease response time, but process
noise can also be detected.
DP Damping Two damping settings are available: level and DP. Level damping
affects loop tuning. Changes to level damping require re-tuning the
controller. DP damping is independent of level output, and does not
affect controller output or loop tuning.
Factory Default: 0 sec
Valid Range for Level Damping: 0 to 32 sec
Valid Range for DP Damping: 0.1 to 27.6 sec
