Information Specific to the DNA Engine Tetrad
of the air exhaust vents on the front and back of the DNA Engine
Tetrad (fig. 12-2). These screws may be replaced with longer ones, as
long as they are M4 x 0.7 screws.
Operating the DNA Engine Tetrad
Turning the DNA Engine Tetrad On
First, make sure Alpha units are installed in all four quadrants. An in-
terlock switch prevents the DNA Engine Tetrad from operating if fewer
than four Alpha units are installed.
Turn the DNA Engine Tetrad on with the « Power » key located at the
lower right of the control panel.
Operating Alpha Units
Alpha unit installation, removal, and general operation are the same as
for the DNA Engine (see chapter 4).
Running Protocols on the DNA Engine Tetrad
Running Separate Protocols by Block
Choose a protocol (see chapter 5). A screen identifying the protocol (2-
STEP in the examples below), the Alpha unit type (96V), and the quad-
rant number of the block the protocol will run on (1) will be displayed:
If a dual-block Alpha unit is present in the identified quadrant, an A or a
B will appear after the quadrant number (e.g., 1A).
Protocols are initially assigned to the first block available in the DNA
Engine Tetrad, in numerical order of quadrants. To run the protocol on a
different block, press «
Block » until the quadrant number of the desired
block is displayed in the screen’s upper right-hand corner. The status
light of the selected block will flash. When a single-block Alpha unit is
selected, only the A light flashes. When a dual-block Alpha unit is se-
lected, either the A or the B light flashes, depending on the block chosen.
