4.4.1. Error / Fault Output
Error/fault conditions are indicated in many ways:
• On the User Interface display
• Through the 4-20 mA analog output
• The Error/Fault relay will de-energize
• The HART digital information will show an error
• The Modbus digital information will show an error
• A fault event will be recorded every 30 seconds

Low Supply
This fault occurs if the supply voltage at the Gassonic Observer-i drops below +12.5 VDC. When
the supply returns to normal, the Gassonic Observer-i will go back to start up.
Action - Ensure that the supply voltage is at least +14 VDC at the Gassonic Observer-i.
