Appendix C - Reference Section
Next to each term is the prompt section it appears in, as appropriate, and the applicable section or page of this
manual. Terms that are printed in all upper case letters appear in the instruments display, or are keypad designa-
tions . In some cases, additional words are inserted for readability.
While many of the terms listed are actually the prompt shown on the first line, the definition refers to the corre-
sponding parameter value, choice, or text. Some prompts appear multiple times in a section or in multiple sec-
tions, with each occurrence having a separate value associated with it.
ACTION ON NEW CHART - Chart Configuration - Page 6-11
Specifies the action the recorder takes when a new chart is installed; NONE - JUST CONTINUE trending, PRINT
a RANGE LIST first, or PRINT a set of SCALES for each pen first.
ACTION TIME SETTINGS - System Prompts - Section 8
Prompt section where values are entered in Time and Date parameters which are used to generate the following
actuators: TIME 1, TIME/DATE 1, TIME 2, TIME/DATE 2,TIME1 TO TIME 2, and TIME/DATE 1 TO 2. The TIME1
and TIME 2 actuators are true when the time is equal to or greater than the time values during each 24 hour day,
and false between midnight and the time specified. The TIME/DATE 1 and TIME/DATE 2 actuators are true when
the time and date are equal to or greater than the time and date values specified, and remain true into the future.
TIME 1 TO TIME 2 is true when the time is equal to or greater than the TIME 1 parameter and less than or equal
to TIME 2 parameter during the next 24 hour period.
Examples: If TIME 1 is set to 8 AM and TIME 2 is set to 4 PM,
then TIME 1 TO TIME 2 is true for 8 hours during the day.
If TIME 1 is set to 10 PM and TIME 2 is set to 6 AM,
then TIME 1 TO TIME 2 is true for 8 hours running through midnight.
Actuators
Digital values (considered to be 1 or 0, true or false, active or inactive) available as choice selections for various
parameters, used to cause some action to occur. For example, A23 is the designation for third alarm on PV2
(Process Variable 2). When PV2 is in alarm, A23 will be 1, true, or active, and if a relay has been configured to be
activated by A23, the relay would be energized.
ALARM SETTINGS - System Prompts - Section 7
Prompt section containing parameters which specify the setpoint of each alarm configured within the Process
Variables section of Configuration.
ALARMS ON ACTUATOR - System Prompts - Configuration - Instrument Settings - Page 4-74
Parameter that selects an actuator which controls whether process alarming is active. When inactive, all process
alarms (A11 through A44) are reset and ignored.
ALARM TYPE - System Prompts - Configuration - Process Variables - Page 4-36
Parameter that specifies the type of alarm: PROCESS HIGH, PROCESS LOW, RATE RAISING, etc.
ALT SPEED ACTUATOR - Chart Prompts - Chart Configuration - Page 6-6
Parameter that specifies an actuator that, when active, switches the chart speed from the NORMAL SPEED to the
ALTERNATE SPEED.
AT VALUE - System Prompts - Configuration - Inputs - Page 4-10
One of the choices for CUTOFF TYPE which specifies that the resultant IV (Input Value) is set to the CUTOFF
VALUE whenever the input valve is less than the CUTOFF VALUE. The CUTOFF VALUE may be positive or
negative, allowing cutoff to occur at any point.
