3.2.2 CONFIGURATION DISPLAYS
During configuration, the upper display shows the parameter codes. The lower digital display
shows the parameter value. During operation, the upper display is used to indicate process
value or deviation from setpoint. The lower display can be used to indicate setpoint value or
proportional output percentage.
3.2.3 MODE SELECTION
If the instrument is in the Control mode, repeated depressions of the SCROLL key will cause
the instrument to display the code corresponding to each mode that is enabled. To enter a
mode, with the mode displayed, depress the DOWN key. Entry into any mode except the
Control, Tune and Enable modes will cause the output(s) to turn off.
Configuration Summary 3.3
All configurable parameters are provided in Tables 3-1 thru 3-3 on the following pages. These
tables illustrate the display sequence, parameter adjustment and factory setting for each step.
The instrument is provided with a “time-out” feature. If the instrument is in any mode, other
than the Control mode, and no keypad activity takes place for 30 seconds, the mode will be
exited automatically. The instrument will then display the code for the respective mode. If a
mode code is displayed for five seconds with no key stroke activity the
“time-out” will cause the instrument to return to the Control mode of operation.
3.3.1 ENABLE MODE CONFIGURATION
The Enable Mode provides a means of enabling or disabling access to setpoint changes and
each of the non-control modes. In the Enable mode, each mode except Control, will be
displayed. Either “on” (enabled) or “oFF” (disabled) may be selected. See Table 3-1 (page
24) for the Enable mode procedure. For additional security the Enable mode may be locked
out by using a hardware jumper, JU 2, located on the Processor board. See Appendix A-2
(page 65).
3.3.2 PROGRAM MODE CONFIGURATION
The Program mode is used to configure or re-configure the instrument. The input and output
selections are made in the Program mode. All possible parameters are illustrated in Table 3-2
(page 29) for illustrative purposes. Only those parameters that are applicable to the hardware
options chosen or to previous parameter selections will be displayed.
