Page 19: General Installation Considerations
Level Controller Overview and Installation GENERAL INSTALLATION The accuracy of a level control measurement depends upon proper installation of the controller and impulse piping. The piping between CONSIDERATIONS the process and the controller must accurately transfer the pressure in order to obtain accurate measurements. Mount the controller close to the process and use a minimum of impulse piping to achieve best accuracy.
Page 20: Mechanical Considerations
The following guidelines have been established to ensure a tight flange, adapter, or manifold seal. Use only bolts supplied with the controller or sold by Rosemount Inc. as a spare part to the Level Controller.

Page 36: Autotuning
AUTO = Automatic Mode ALL = All Modes AUTOTUNING The Model 3095 Level Controller is available with Rosemount’s Autotuning algorithm, which accurately determines the optimal tuning parameters for a level control loop without operator interaction. The Autotuner algorithm is specified by the “CC” option code in the level controller ordering table.
Page 37: Why Autotune
Level Controller Configuration Why Autotune? A poorly tuned loop results in poor process level control and excess stress on the control element. Figure 3-3 illustrates the relationship between the Control Signal percentage and the Level (or, percent of tank height) of a poorly tuned loop. FIGURE 3-3.

Page 43: Configuration Overview
Section Level Controller Configuration This section describes the tasks involved in configuring the Model 3095 Level Controller. CONFIGURATION Configuring the Level Controller consists of four major tasks: OVERVIEW 1. Set Up the Level Calculation: These tasks set up the Level Controller for the specific process, and include setting process density, level units, controller height, and damping.
Page 44: Set Up The Level Calculation
The control signal remains fixed at the value when OOS mode was entered until the OOS mode is exited. The Model 3095 Level Controller is shipped in OOS mode. Before configuring the controller, ensure that the controller is in the OOS mode (Out-of-Service).

Level Controller Configuration Set Mode Shed Options See page 3-9 for details about Mode Shed. (Failure Condition) Shed Action Shed Action selects whether the controller remains at its present value (hold output) or goes to the shed output value if the Level Controller HART Comm.
Page 50: Set Auto Output Limits
™ Rosemount Model 3095 Multivariable Level Controller Output limits determine the allowable minimum and maximum control Set Auto Output Limits output values when the controller is in automatic mode. Output Hi Limit For example, the minimum allowable control output may be 7.2 mA (20% of valve stroke) and the maximum allowable control output may HART Comm.
Page 51: Additional Options
Level Controller Configuration Additional Options The following options are not required for Level Controller operation. Setpoint Tracking When enabled and in manual mode, setpoint tracking automatically changes the setpoint to the measured level value. This option is valid in HART Comm. 6, 2, 2, 6 manual (MAN) mode only.
Page 52: Perform A Level Trim
™ Rosemount Model 3095 Multivariable Level Controller Performing a level trim is recommended for all field installations. Level PERFORM A LEVEL TRIM trim can be done in OOS and MAN mode; it cannot be done in AUTO mode (see page 4-2).
Page 53: Tune The Loop
Level Controller Configuration TUNE THE LOOP At this point, you should tune the loop according to industry accepted practices. See “Autotuner” on page 4-12 if you have purchased the Autotune feature (Option Code CC). If you do not have Autotune capabilities, follow the instructions in “Set Control Tuning.”...
Page 54: Autotuner (Optional)
™ Rosemount Model 3095 Multivariable Level Controller This selection sets the controller bias value. (This parameter is Manual Bias sometimes called manual bias or manual reset.) HART Comm. 6, 2, 1, 6 This value is only used if the Control Type is set to P or PD. This setting is used as the controller bias term for the P or PD algorithm equations.
Page 55 Level Controller Configuration Alpha is the loop performance factor used to adjust the loop response. Alpha A lower value results in more aggressive control while a higher value HART Comm. 6, 2, 4, 3, 3 results in more conservative control. Once the system has been autotuned, the Alpha parameter may be revised and new tuning parameters will be calculated.
Page 56 ™ Rosemount Model 3095 Multivariable Level Controller This selection sets the maximum time allowed for the autotuning Time Limit procedure to complete. If tuning does not complete within this time HART Comm. 6, 2, 4, 3, 5 frame, tuning will cease and a message is displayed indicating that tuning failed.
