Loop Parameters
This section of the Output Loops Setup window includes the fields described below.
Output Loop Displays the number of the analog current loop that is to be configured.
Loop function Allows you to enable or disable the output loop operation.
Loop type Allows you to select between current loop ranges of 0 - 1 mA and 4 - 20
mA.
Note:
If requested at the time the monitor is ordered, this field can be
made to select between current loop ranges of 0 - 1 mA and 0 -
10 mA.
Custom Range
This section of the Output Loops Setup window allows you to select the value range for the
current loop output.
Example: An RTD measures temperatures from -40 - 120° C. You select an output of 4 - 20
mA and a custom range of 0 - 100. For temperature measurements of:
•
−
40 - 0° C, the current loop output will read 4 mA
• 0 - 100° C, the output will correspond directly to 4 - 20 mA
Any temperature measurement over 100° C will continue to read 20 mA.
The fields in this section of the Output Loops Setup window are described below.
Use Custom
Range Allows you to activate the custom scaling of the analog outputs by
clicking to put a check mark in the check box.
Minimum Allows you to enter a value that corresponds to 0 mA for a 0 - 1 mA
output, or 4 mA for a 4 - 20 mA output loop.
Maximum
Allows you to enter a value that corresponds to 1 mA for a 0 - 1 mA
output, or 20 mA for a 4 - 20 mA output loop.
