POWER - the d.c. connector for control console
main power. The input voltage to the console is sup-
plied from the load frame, where a d.c. power sup-
ply is located that provides d.c. power for the entire
system.
mm/IN/SI switch - a 3-position rocker switch for
setting the operating units (S.I., English, or metric)
of parameters in the load and extension channels.
Installing Cables
For Series 4400 systems, cabling to the console includes
cables for load frame interface, a load cell, an exten-
someter, and a d.c. power cable. In addition, options
such as a recorder, a printer and a computer also connect
to the rear panel of the console, using the cables pro-
vided with these options.
To install cables:
(a) Match the individual cables with their proper connec-
tors on the rear panel of the console (see Figure 3-1).
(b) Press the cable connector into its mating connector
on the rear panel. Use a small screwdriver to insert
and tighten the cable connector screws. If you do not
do this, cables may fall off during a test.
Caution
Do not allow the cables to droop in
a haphazard manner from the rear
of the console.
