Power (Green) Indicates when power is applied to the Vacuum Degasser -
cable is plugged in and Power switch turned ON.
Status (Yellow) Indicates when vacuum level is outside the acceptable oper-
ating range. This LED will light at initial power-up and remain
on during pump-down. It will turn off after a few minutes
when the vacuum level goes below 100 mm of Hg absolute.
If an error condition occurs, this LED will flash in one of two
modes:
Flashing on and off in even 1-second intervals: pump was
not able to reach vacuum set point, indicating a possible
leak in the system.
Flashing on for 1 second and off for 2 seconds indicates a
vacuum signal error.
Vacuum (Green) Indicates when vacuum level is within the acceptable operat-
ing range. The LED will light up after the initial pump-down,
and remain on as long as the Vacuum Degasser is powered
up and the vacuum level is below 100 mm of Hg absolute.
