Input Settings

Description

 

Display

Select to enable or disable a scaled input value to be displayed with designated title

 

 

and units in the web manager, XML and CLI analog chanel as well as Tunnel and

 

 

Action Connect application. You can hide an input by disabling it if you are not using it.

 

 

 

 

Title

Enter the analog input title as it will appear in web manager, XML and CLI. Leave this

 

 

field blank to utilize the default “Input N”, where N is the analog input number. For

 

 

example, you can name the reading, “Temperature”, if a temperature sensor is

 

 

connected to the xSenso device.

 

 

 

 

Range

Select input range from drop-down menu. Select the measurement range closest to

 

 

your sensor output to get the most accurate measurement.

 

 

Select 20mA when input is connected to the I+ and I- terminals.

 

 

Select 100nV, 1V or 10V when input is connected to the V+ and V- terminals.

 

 

 

 

Adjustment

Select the offset adjustment:

 

 

Select Simple offset so that the offset value is simply added to each analog input

 

 

with the result presented as an analog reading.

 

 

Select Scale and offset to linearly map each analog input sample to its reading value

 

 

via specification of two points (one near each end of the linear mapping range).

 

 

 

 

Input Low

Enter the Input Low value which will be presented as the Reading Low value. For

 

 

example, if a sensor measures -40°to 100°C with an output of 0 to10V, you can input

 

 

input low 0°, input high 10°, reading low -40°, reading high 100° and unit "C".

 

 

 

 

Reading Low

Enter the Reading Low value which will be converted from the Input Low value.

 

 

 

 

Input High

Enter the Input High value which will be presented as the Reading High value.

 

 

 

 

Reading HIgh

Enter the Reading HIgh value which will be presented as the Input HIgh value.

 

 

 

 

Offset

Enter the offset value through which each sampled analog input value may be

 

 

adjusted. Offset may be positive or negative.

 

 

 

 

Decimal Point

Specify the maximum number of digits to be displayed to the right of the decimal point,

 

 

according to the accuracy of signal source. Reading is always limited to have at 5

 

 

significant figures at most. For example, if the connected analog output sensor has an

 

 

accuracy of 0.1°C, you can select decimal point to be 1.

 

 

 

 

Units

Enter the unit as it will appear after the presented analog input value. For example, you

 

 

can input C or F if a temperature sensor is connected.

 

 

 

 

Alarm Type

Select alarm type to enable monitoring for high and/or low analog input readings:

 

 

Select either High or High and Low to enable monitoring for a reading at or above

 

 

the specified Alarm High value.

 

 

Select Low or High and Low to enable monitoring for a reading at or below the

 

 

specified Alarm Low value.

 

 

Select None to disable monitoring reading for alarm low and/or high values.

 

 

 

 

Alarm High

Specify the Alarm High value; an analog input reading above this value that persists

 

 

for Delay seconds will turn on the alarm.

 

 

 

 

Alarm Low

Specify the Alarm Low value; an analog input reading below this value that persists for

 

 

Delay seconds will turn on the alarm.

 

 

 

 

Delay

Specify the Delay value in seconds; an analog input high or low reading that persists

 

 

for Delay seconds will turn on the alarm.
