PME - How to change ZBRN CH110 and TH110 temperature readings to Fahrenheit using Device Type Editor

Issue

A ZBRN32 (CL110/TH110) device connected in PME doesn't have an option to change the temperature sensor readings to Fahrenheit. By default, they are in Celsius.

Resolution

1. Open File Explorer, then navigate to …\Program Files (x86)\Schneider Electric\Power Monitoring Expert\system\translators.

2. Copy the ZBRN32_CL110_TH110.ion and ZBRN32_CL110_TH110.xml files.

3. Navigate to …\Program Files (x86)\Schneider Electric\Power Monitoring Expert\config\translators.

4. Paste the ZBRN32_CL110_TH110.ion and ZBRN32_CL110_TH110.xml files into this folder.

5. Open Management Console > Tools > System > Device Type Editor.

6. File > Open, then navigate to …\Power Monitoring Expert\config\translators.

7. Open the ZBRN32_CL110_TH110.ion file.

8. For each of the Sensor ## Temperature registers, set the Multiplier = 1.8 and Offset = -1778

9. File > Save and close Device Type Editor.

If changing temperature measurements for another device type, refer to the calculations below for reference:

• Celsius to Fahrenheit is F = (C * 9/5) + 32
• Scale, Offset, and Multiplier is ION value = (Modbus value - offset) * multiplier / scale
• The Celsius to Fahrenheit formula can be rewritten to match the Scale, Offset, and Multiplier formula using the following:

• If Scale = 1, set Offset = -17.77 and Multiplier = 1.8
• If Scale does not equal 1, multiply the Offset by the Scale.
