ABB Uvisor SF910i, User Manual

Page: 113 / 190

Whenever any of the above condition is met:
– SF910i stops program execution and shows on the display as the error code “noise
detected”.
– All outputs are brought in safe state:
• SF910i sends the noise detected fault message over the serial line.
• The associated flame relay will be de-energized.
• The associated channel LED will blink red.
• The Fault-relay LED will blink red.
For safety reasons, the Flame Scanner normal operations after a fatal error code are
triggered, can only be recovered by cycling the power supply.
