If the setting is one of a list of choices, the choice line containing the current choice will be displayed and the current choice will blink. If multiple choices are displayed, the LEFT ARROW or SCROLL keys will move the selection to the left or right. If all choices are not displayed at once, due to multiple choice lines, the UP ARROW key will step backward to the previous choice line, or the DOWN ARROW key will step forward to the next choice line. Pressing the ESC key will exit Modify and the original setting will be displayed, no change being made to it. Pressing the ENTER key will exit Modify and the new setting will be displayed and entered into memory.

A choice line may offer 1 through 5 choices. Pressing the Special key located directly below the desired choice, will select and enter that choice into memory.

3.4.4 COPY/INITIALIZE

A COPY/INITIALIZE capability is available with some parameter sections. If COPY is selected, the unit automati- cally goes into Modify on its associated value and uses its associated number as an index and copies data from one set of elements into the current set of elements. If the associated number is set to zero, the factory default values are stored into the selected set of elements (INITIALIZE). The COPY function applies to all parameter entries following it until the next non-parameter entry.

3.4.5 PASSWORDS

Where PASSWORDS apply, they are not displayed if the current value of the password is zero. If PASSWORDS are not zero, and the value is set to the correct password, the unit automatically proceeds to the next parameter entry. If PASSWORDS are not zero, and the value is set to the incorrect password, the message "INVALID PASSWORD" will appear in the upper display.

3.4.6 ENABLES

If Chart Prompts is DISABLED, when the CHART key is pressed, the message "CHART KEY DISABLED" will appear in the lower display. If Display Prompts is DISABLED, when the DISP key is pressed, "DISPLAY KEY DISABLED" will appear in the lower display. If other parameters are DISABLED, their corresponding prompts will not be displayed.

3.5 THE DISPLAY

During normal operation, the display shows data according to the setup determined by the settings in Display and Configuration prompts.

The display has 2 lines of 20 characters with 8 status indicators.

The display may be configured as continuous or sequential, as well as 1 value at a time, 2 values at a time, or 4 PVs at a time. Refer to Section 3.7 for details.

3.6 GENERAL

After completing installation and wiring of the instrument, the configuration procedures must be performed to prepare the instrument for operation on the intended application. The procedures include selecting specific prompts/parameters, entering data and possible jumper positioning. Once properly configured the instrument will retain the selections in memory. Not all selections are applicable for every recorder.

Note: Before configuring, it is recommended that the Software Reference/Record Sheets (found at the end of this section) be completely filled in.

Parameter selections and data entry are made via the keypad. To ease configuration and operation, user entered data has been divided up into three sections referred to as Main Prompts. The three are: System, Display, and Chart. Each prompt contains different type of data; chart for the chart, Display for the Display, and System, as follows:

CONFIGURATION--ACTION TIME SETTINGS--ALARM SETTINGS--ENABLES/PASSWORDS--TEST-- CALIBRATION--MODEL/REV
