Chapter 5: Panel Indicators and Controls
Front panel
The Stir/Purge front panel includes one valve knob, one 16-position control knob, two 3-position toggle
switches, one 2-position toggle switch, and four LED indicators. Each of these is discussed in this chapter.
The POWER Switch and LED
The POWER Switch and LED are located on the right of the Stir/Purge front panel. When the toggle switch is in
the “ON” (up) position, the LED normally glows a steady blue.
When the POWER LED is off one or more of the following conditions may apply:
•
The front panel power switch is off.
•
There is no DC +12 V supply connected to the rear-panel DC POWER IN connector.
•
The external DC power supply has no input power or is malfunctioning.
• The internal power switch is faulty.
REMOTE LED
An LED is located to the left of the POWER toggle/LED. This LED is lit when one or both of the STIR or GAS
switches are in the REMOTE position.
Stir Speed Knob
To the left of the REMOTE LED is the STIR SPEED Knob. This is a 16-position control knob. The bottom
position is “Off” and the stir speed increases from the lower left, clockwise, through the remaining 15 positions
