However, the raw analog input value displays the actual voltage or current measured at the analog
input as long as it is within the voltage or current range detected by the input circuit.
8. Min Input Current (mA) - This setting defines the minimum input current level expected for the input.
When the input current falls below this level, the out-of-range condition is annunciated if it is
configured as alarm or pre-alarm. If the Input Type is set for Voltage, this setting is disabled.
9. Max Input Current (mA) - This setting defines the maximum input current level expected for the input.
When the input current rises above this level, the out-of-range condition is annunciated if it is
configured as alarm or pre-alarm. If the Input Type is set for Voltage, this setting is disabled.
10. Min Input Voltage (V) - This setting defines the minimum input voltage level expected for the input.
When the input falls below this level, the out-of-range condition is annunciated if it is configured as
alarm or pre-alarm. If the Input Type is set for Current, this setting is disabled.
11. Max Input Voltage (V) - This setting defines the maximum input voltage level expected for the input.
When the input rises above this level, the out-of-range condition is annunciated if it is configured as
alarm or pre-alarm. If the Input Type is set for Current, this setting is disabled.
Four thresholds can be set for each analog input. There can be two “over” thresholds and two “under”
thresholds. Each analog input can be configured as an Alarm, Pre-Alarm, or as Status Only. If any type
other than None is selected, the threshold status is available to BESTlogicPlus Programmable Logic. This
allows the user to set up an over and under pre-alarm threshold, and over and under alarm threshold.
An Activation Delay can be set for the thresholds. Over Threshold 1 and Under Threshold 1 share a
common activation delay. Similarly, Over Threshold 2 and Under Threshold 2 share a second activation
delay. See Figure 7-26.
12. Threshold 1
a. Under Threshold - This parameter defines when Status, Alarm, or Pre-Alarm is annunciated.
b. Under Threshold Alarm Configuration - Select None to disable, Status Only to make the
threshold status available to BESTlogicPlus Programmable Logic, Pre-Alarm to annunciate a
pre-alarm, or Alarm to annunciate an alarm.
c. Over Threshold - This parameter defines when Status, Alarm, or Pre-Alarm is annunciated.
d. Over Threshold Alarm Configuration - Select None to disable, Status Only to make the
threshold status available to BESTlogicPlus Programmable Logic, Pre-Alarm to annunciate a
pre-alarm, or Alarm to annunciate an alarm.
e. Activation Delay(s) - This setting defines how long a Threshold 1 condition must be true
before an alarm or pre-alarm is annunciated. This time is shared by both Over Threshold 1
and Under Threshold 1 detection.
13. Threshold 2
f. Under Threshold - This parameter defines when Status, Alarm, or Pre-Alarm is annunciated.
g. Under Threshold Alarm Configuration - Select None to disable, Status Only to make the
threshold status available to BESTlogicPlus Programmable Logic, Pre-Alarm to annunciate a
pre-alarm, or Alarm to annunciate an alarm.
h. Over Threshold - This parameter defines when Status, Alarm, or Pre-Alarm annunciation is
desired.
i. Over Threshold Alarm Configuration - Select None to disable, Status Only to make the
threshold status available to BESTlogicPlus Programmable Logic, Pre-Alarm to annunciate a
pre-alarm, or Alarm to annunciate an alarm.
j. Activation Delay(s) - This setting defines the duration that a Threshold 2 condition must be
true before an alarm or pre-alarm is annunciated. This setting is shared by both Over
Threshold 2 and Under Threshold 2 detection.

Many of the settings for the Remote RTD Inputs are similar to the settings for Remote Analog Inputs. See
Figure 7-27.
