Operating The Sitrans Lr 400 - Siemens SITRANS LR 400 Instruction Manual

Operating the SITRANS LR 400

To access parameters, use the optical control elements on the operating and monitoring
module (shown below). Touch the glass in the appropriate place with your fingertips like
on a touch screen. The two-line LCD displays the parameters. You can alter the setting or
change to other parameters using the controls.
Operating and Monitoring Module
Selecting a Parameter
The first line of the display tells you the current operating level. The second line indicates
one of the parameters you can access under the parameter group. If the level offers more
than one parameter, you can have them displayed in cyclic order by using the control
elements (forwards) and
parameter currently displayed on the second line. The fourth control element,
this parameter and moves up one level until you return to the multi-display.
When you select a parameter, the device displays the parameter's current value in the
second line. When the value flashes, the device programming is enabled (see "Disabling
and enabling programming" on page 22) and you can change the current setting. There
are two different ways of changing the settings, which are explained in the following
sections.
Note:
The background illumination of the LCD switches on automatically as soon as
you use a control element. It goes out about three minutes after last use of a control
element.
