How to Wire and Calibrate a Thermocouple?
Wiring a thermocouple
|Temperature is provide by a thermocouple sensor connected to a ACE PLC
ACE 1450, 3090, 7096,.. have thermocouples inputs.
Our Type K thermocouple is wired as follows:
Sometimes, with other thermocouples, the + and – can have different colours. See the thermocouple manual.
Calibrate the thermocouples
After selecting the correct thermocouple (Type K) in the configuration wizard…
Choose “Calibrate Thermocouple” from the vBuilder menu.
|Check therocouple you’d like to calibrate
Inputs F1, F2, F3 or F4 forACE-3090 as example
Set the current temperature, then, press calibrate
You can select a second point to obtain a more accurate measurement.
For example, 21°C for the first point and 0°C for the second point.
If you copy the thermocouple input (InFloatF4 in our case), into any other tag, just to see the value in debug mode, you will see the temperature appear.
