SITRANS LC 500 – INSTRUCTION MANUAL

7ML19985GE01

Displays the Fault/Failure information. If operation is normal, two test displays alternate, 
which light up all the LCD segments in a cycle. If there is a fault or failure, an error code is 
displayed. See the detailed list of error codes and their meanings, page 53. 

Set the rotary switch to 1. 

To change the state of the output signals, press and hold both buttons simultaneously: the 
digital mode outputs (the solid-state switch and the loop-current control in digital mode) 
change to their opposite state. Thus 4mA becomes 20mA and contact open becomes 
contact closed. This feature allows you to verify that the output signals are properly 
processed further on in the PLC/DCS system: if the normal state is non-alarm, changing 
the state should generate an alarm.

The outputs stay in the opposite state as long as both buttons are pressed.

Displays whether the factory settings are still in place, or how much they have been 
changed, and allows you to restore the factory settings. 

Set the rotary switch to 2. To restore the factory settings, press both buttons 
simultaneously to change the LCD to ‘do it’ and hold both buttons for more than one 
second. When the buttons are released, the LCD displays FAC A.
