SET UP THE LEVEL
CALCULATION
These tasks set up the Level Controller for the specific process.
Place Controller into
Out-of-Service
(OOS) Mode
Target Mode The user can select the mode of the control function to be MAN
(manual), AUTO (automatic), or OOS (out-of-service).
• In automatic mode, the controller output is determined by the
control function, where a control algorithm sets the control
output value.
• In manual mode, the controller output is adjusted by the operator
via digital communications or the local operator interface.
• In out-of-service mode, the operator can configure the controller
without changing the control signal. 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).
Factory Default: OOS (Out-of-Service)
Valid Options: OOS, AUTO, MAN
NOTE
To complete a change of mode, press the “SEND” key on the
HART Communicator.
Set Density
Density This selection sets the nominal density of the process material. The
Level Controller does not compensate for compressibility or thermal
expansion of process materials. Level calculation will assume a
constant density.
Factory Default: 1 g/cm

Set Level Units
Level Units This selection sets the units of measure for the following parameters:
level value, controller height, level range, setpoint, setpoint limit, and
static error.
Factory Default: Inches
Valid Units: In, ft, cm, m
