INPUTS - System Prompts - Configuration - Page 4-1
Prompts section that configures how hardware inputs are processes to provide the desired engineering values,
decimal position, and units, for the sensor type and range used. Other characteristics are also configured for out-
of-range checking, cutoff, input correction, filtering.
INPUT TYPE/RANGE - System Prompts - Configuration - Inputs - Page 4-3
Specifies whether the input type is thermocouple, RTD, volts, milliamps, millivolts, pulse, switch, or not used (OFF
- NO INPUT).
INSTANTANEOUS VALUES - System Prompts - Configuration - Recorders - Page 4-46
The choice for the parameter RECORDING METHOD that prints a single dot corresponding to the instantaneous
value of the trended value at the end of the “print interval”. This method records a series of dots which may not
form a continuous trend line.
INSTR. ON ACTUATOR - System Prompts - Configuration - Instrument Settings - Page 4-73
Parameter used to specify an actuator which controls whether the instrument’s outputs are active. When inactive,
all outputs (relays, mA, LEDs) are reset, totalizing is stopped and the instrument displays the Instrument Tag and
“INSTRUMENT OFF”. The instrument continues to scan and process inputs, derived variables, process vari-
ables, alarms (but with no relay outputs), times and dates, actuators, derived variables, records and collects data.
INSTRUMENT SETTINGS - System Prompts - Configuration - Page 4-72
Prompts section that configures various instrument wide parameters, such as instrument tag, time and date
formats, the current date and time, and some special actuator selections.
INSTRUMENT TAG - System Prompts - Configuration - Instrument Settings - Page 4-72
Parameter used to specify a description or designation that can be displayed with the current time and date in the
Display Sequence.
LED ACTUATOR - System Prompts - Configuration - LEDs - Page 4-65
Parameter that selects an actuator, which, when true, causes the specified LED, 1-8, to be lit.
LEDS - System Prompts - Configuration - Page 4-64
Prompts section that configures actuators for the LEDs.
LOW FLOW CUTOFF - System Prompts - Configuration - Totalizers - Page 4-57
Parameter that specifies the value below which the flow will not be added to the total. If the flow rate is negative,
the flow will be subtracted if the value is more negative than the magnitude of the LOW FLOW CUTOFF value
specified. If negative flow totalization (subtraction) is not desired, the negative flow rate must be cutoff at the
input using CUTOFF TYPE and CUTOFF VALUE. For example, if LOW FLOW CUTOFF is 100 GAL/HR, positive
flow of 0 to 99 GAL/HR will not be totalized, but negative flow of -101 or more negative would be totalized (sub-
tracted).
Major time lines
Major time lines are printed as a series of dots, with noticeable spacing, and extend from the inner chart ring to
the outer chart ring. The number of major time lines printed on the chart is determined by the MAJOR TIME
PERIODS parameter in the Chart Configuration. The color of the major time lines is programmable.
MAJOR TIME PERIODS - Chart Prompts - Chart Configuration - Page 6-4
Parameter that specifies the number of periods or sections the chart shall be divided into. This also corresponds
to the number of “major time lines” printed, and indirectly, the time between them.
MATCH/SELECT - Chart Prompts - Chart Configuration - Page 6-8
Parameters which specify whether time lines, times, and dates and chart tags should be in the same color as the
scale just printed, or always be a fixed color.
