OPERATION

2.7.11  Status LED or Light Guide

The Status LED or Light Guide options have identical functionality and take their input 

from the same board. Therefore, only one of them can be selected. 

For either option the information available is as follows:

Power LED

 

• 

Green LED On – indicates instrument power is on.

Status LED 

• 

Red  LED  flashing  –  indicates  when  external  compensation  input  or 

external sensor is out of range (if either is selected to 

ON

ON

). Out of range 

is <3.2mA or >21.4mA (see Status Message Table in Section 2.5.1).

• 

Red  LED  On  –  indicates  an  internal  sensor  error  or  instrument  cell 

temperature not yet stabilized (see Status Message Table in Section 2.5.1) 

– for LED indication this takes priority over external errors.

These have been designed to follow the NAMUR standard.
