3.1 Installation
Local, "Single" Mode Installation Testing
Local mode testing allows an operator to enter pressure set points by using the
Supervisor keypad.
The procedure outlined below can be used without the need for detailed reading of
the operator's manual. To begin local mode testing, close and seal the furnace
end cap. It is recommended that an initial inert process gas input of nitrogen at 10
liters per minute be used. Turn on system power to the Supervisor by depressing
the power switch to the ON position. The Supervisor display contrast can be ad-
justed with the potentiometer on the Supervisor lower connector (see Figure 3-5).
Turn the potentiometer clockwise to darken the display characters. Too much
contrast will saturate the entire display matrix to black. Turn the potentiometer
counterclockwise to lighten the display characters.
1. Use the up-arrow key [] (see Figure 3-6) to scroll the menu item in the upper
left corner of the LCD display to the "StptMode" (Set point Mode) entry (see
Figure 3-7). If the setting for this entry is "Analog" it must be changed to "
Single".
2. Change the set point mode from "Analog" (analog remote set point) to "Single"
(digital set point) by first pressing the star key [*]. A "*" should appear in front
of "StptMode". Next use the up-arrow key [] (or down-arrow key []), so that
the mode word "Single" appears next to "StptMode" (see Figure 3-7). Then
press the enter key [ENT], at which point the "*" designator disappears from
the screen indicating the new mode has been accepted by the Supervisor. The
Supervisor is now in local mode.
