Start up Procedures 3.4
All configuration parameters are listed in Tables 3-1 through 3-5.
For a single pen instrument, parameters for each mode are displayed in the left display. If the
instrument being configured is a two pen model, a sequence of applicable parameters will be
displayed in the Pen 2 display after the Pen 1 parameters have been reviewed and config-
ured. After the Pen 2 parameters have been completed, parameters common to both pens will
be configured and displayed in the Pen 1 display.
The instrument is provided with a time out feature. If the instrument is in any mode (except
while executing a calibration or test procedure) and no keypad activity takes place for 30
seconds, the instrument will time out and exit the mode automatically. The display will become
the code for the respective mode. If a mode code is displayed for 5 seconds with no keypad
activity, then the time out will cause the instrument to proceed to either the Control or Off
mode, depending upon whether the mode entered was an operational mode (Tune, Manual,
Enable) or non operational mode (Test, Program, Cal).
3.4.1 POWER UP PROCEDURE
Step 1
Verify that all electrical connections have been properly made before applying power to
the
instrument.
Step 2
Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show
the instrument is "alive". Then 8XXX will be displayed (X representing digits), then XXXX,
then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the
EPROM part number will be indicated P-XX. After the EPROM part number, the software
revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power
Up, PAPu, in Program Mode is set to 0, pens go to "home" position on power up). During this
display, the decimal point after the "P" will blink to show the mode is active. Upon successful
completion of this routine, CtrL, OPEr or oFF will be displayed for about three seconds. The
mode displayed will be the mode that the instrument was in when the power was turned off.
During this time the operator may select another mode (Tune, Manual, Enable) or non-
operational mode (Test, Program, Cal).
Step 3
If any error messages are displayed, refer to Section 5.6 (page 55) for a definition of the
error message and the required action.

seven segments and is capable of producing numeric characters from 0-9 and certain alpha
characters. The digital display is used to provide indication of process variable as well as
displaying codes used for configuration and operation of the instrument. The display includes
the following Status Indicator LED’s;
