Power Supply Lamp

Power Supply Lamp
The power supply lamp is integrated into the main power switch. When the
lamp is illuminated (green), the power is ON.

Instrument Status Indicator

The instrument status indicator indicates one of three possible instrument
conditions.
• When the lamp is OFF, the micro vacuum degasser is in ready condition
(only if the power supply lamp is ON, otherwise, the instrument is
switched off, or there is a defect in the power supply). A ready condition
exists when there is sufficient vacuum in the micro vacuum degasser.
• A busy condition is indicated, when the lamp is yellow. A busy condition
exists when the vacuum pump of the micro vacuum degasser is working to
generate or maintain vacuum in the chambers. This is the case when the
micro vacuum degasser is turned on for the first time or the pressure rises
above its limit during normal operation.
• An error condition is indicated, when the lamp is red. An error condition
exists when the micro vacuum degasser detects an internal defect that
does not allow the vacuum to be built up in a certain time frame
(approximately 8 minutes).
If the error LED is on, there is either an internal leak in the vacuum system or
an electronic failure. In case of an internal leak it is possible that solvent may
enter the vacuum chamber and solvent may leak into the waste drain. To
prevent any damage of the micro vacuum degasser, switch off the micro
vacuum degasser and remove the solvent bottles from the solvent cabinet to
stop any gravity-caused flow of solvent into the vacuum chamber.
