4.5 CONFIGURATION
Use ROCLINK Configuration Software to configure the Sensor inputs for an EF-Series Unit.
♦
The differential pressure is configured at Analog Input Point Number A1.
♦
The static pressure (gauge or absolute) is configured at Analog Input Point Number A2.
♦
The Resistance Temperature Detector (RTD) is configured at Analog Input Point Number A3.
The initial pressures are read from the defaults contained within the Sensor. The initial range of the
differential pressure is 0 to 250 inches of water and the static pressure is either 0 to 800 psi (55.15 bar)
or 0 to 3600 psi (250 bar) depending upon the sensor installed. The ranges can be changed through the
calibration routines. It is recommended that the turndown on the range not be greater than what is
given in the Specifications table on Page 4-8.
The Sensor also supports the conversion of values to metric units. In metric mode, both the differential
pressure and the static pressure are in kPa. To set the metric mode, using ROCLINK for Windows
Configuration Software:
1.
Select the ROC menu.
2.
From the pull down menu, select Information.
3.
In the ROC Information window, ensure that the General tab is selected. In the Units area,
click on the Metric radio button.
4.
Click on OK.
To set the metric mode, using ROCLINK (for DOS) Configuration Software:
1.
Select the System menu.
2.
From the pull down menu, select Information.
3.
On the system information display under Units, enable the Metric field.
4.
Press (F8)Save.
The EF-Series Unit automatically adjusts the units, ranges, alarm limits, and calibration factors of the
differential pressure, static pressure, RTD, and enclosure/battery temperature to the Metric mode. To
return to US units, enable the “US” field and save this change to the flow computer. The EF-Series
Unit adjusts the values to US units.
