Installation and Setup
X-320M™ User's Manual
-
Frequency Input:
This option is used if the AUX1 or AUX2 sensor outputs a frequency.
-
1-Wire Bus:
This option is used if the AUX1 or AUX2 sensor uses the 1-Wire Bus protocol.
-
Rmt Analog 1-4:
his option is used if the AUX1 or AUX2 sensor used is an analog sensor
that is being read from a remote Analog device, such as another X-320™ or Analog Module.
1-Wire Address (only shown if 1-Wire Bus is selected in Sensor Connection)
Each 1-Wire sensor comes from the factory with a unique, non-changeable address. When the AUX
tab is selected, X-320M™ scans the bus for sensors. The addresses of the sensors that are found
on the bus are listed in the drop-down list.
Once a sensor is found on the bus, select the appropriate sensor address from the drop-down list to
use that sensor for the 1-Wire sensor measurement.
Description:
This field is used to describe the sensor connected. It can be a maximum of ten characters long.
The default description is
AUX1
or
AUX2
.
Slope
In many cases, the inputs must be scaled to represent “real-world” measurements. X-320M™ reads
the “raw” value from each input, and calculates the number that represents the “real-world”
measurement that the user is actually interested in. This real-world value (referred to as the “Scaled
Value” in this manual) is calculated using the following linear formula:
Scaled Value = Slope * Input + Offset
The Scaled Value is displayed on the
Status Page.
It is also used to determine alarm conditions,
and is shown in email messages.
“Slope” in the formula above is provided by the user and is entered in this field. The value is used to
scale the input to the range of detected condition.
The default value for this field is
1
.
When the Slope is set to 1 and Offset is 0 (default values), the Scaled Value equals the Input Value.
Offset
The “Offset” is used for the “zero” measurement. The default value for this field is
0
. When both the
slope and offset are set to their default values, the Scaled Value equals the Raw Input.
High Alarm
This setting is used to set the trigger point for a high alarm condition. The alarm is triggered when
the value at the sensor exceeds the High Alarm Value. The default High Alarm is
20
.
Low Alarm
This setting is used to set the trigger point for a low alarm condition. The alarm is triggered when the
value at the sensor drops below the Low Alarm Value. The default Low Alarm is
10
.
