Start Up

Self-test

The device performs a self-test after power is supplied. Then, the unit is ready for
programming when the multi-display appears.
Note:
Frequent switching off and on of the device causes aging of the electronics
(see Parameter 3.1).

Multi-display

The multi-display shows on the LCD after a successful self-test with the output of the
level in the first line and the signal-to-noise ratio in the second line (factory setting):
+ 1 2
+ 3 0

Local Programming

When the multi-display appears on the LCD, begin
local programming using the hand programmer. To
access the parameter settings, press LEFT
Main Menu is displayed in the first line of the LCD.
Then program the unit beginning with the Auto-Setup
parameters.

Auto-Setup

After switching on the SITRANS LR 400, and after a successful self test, press LEFT
to access the parameters. Set the Auto-Setup parameters to make the system
operational: (see page 33)
• The language of the local user interface
• The unit of length of the measured level
• The nozzle height in the selected unit of length
• The vessel height in the selected unit of length
• The LRV as a distance from the bottom of the vessel
• The URV as a distance from the bottom of the vessel
• The damping of the measured level in sec
• The application type
• The bus-address by PROFIBUS PA communication (on PROFIBUS models)
Enter the necessary values as described in Parameters on page 33.
Note:
It is strongly recommended that a Customer Code (Parameter 5.2) be entered
after all programming is completed to secure the programmed values from changes.
If the multi-display does not appear or displays incorrect measured values after Auto-
Setup, proceed as described in Troubleshooting on page 75.
Refer to the Parameter section that begins on page 32 for a list of available parameters.
