Self Test Routine
This section provides information about the automatic
self test feature of the Series 4400 console.
The Self Test Routine consists of two parts as described
in this section. It is initiated when power is applied to
the control console, and cannot be bypassed. The pur-
pose of the Self Test Routine is to assure that the con-
sole performs reliably before allowing normal operation
(also refer to the Calibration Overview, page 5-8). The
duration of the self test is only several seconds, and it re-
quires no operator input or interaction other than obser-
vation of the results of the two-part sequence. If there
are no failures indicated, normal operation can start im-
mediately after the test.
Self Test - Part 1
Apply main power to the console using the system
power switch on the loading frame. Within 2 seconds,
all front panel LEDs light at the same time, including
the status indicators and the crosshead control panel
switch LEDs. Also, at the same time, all front panel dis-
plays (LCDs) show the following numeric coding for 5
to 10 seconds.
During this first part of the self test, you should scan the
panels and check that all LEDs light and all LCDs dis-
play the proper number. If service is required, report the
exact condition.
