8.1. Display and alarm reset
If the oil mist concentration is high, the LED indicator will increase and at 70% opacity of the
set alarm threshold, the
“Oil Mist Alarm” LED comes on. At 100% opacity relative to the set
alarm threshold, the
“Oil Mist Alarm” LED will start flashing. If the opacity subsequently
decreases, the alarm status is saved.
