7.2 FAQs

7.2.1 How do I change from a J to a K thermocouple?

Every Series RMB controller is shipped ready to accept input from a J thermo

couple. If you plan to use a K thermocouple for input, you must set

SW2-switch 2 to ON as described in Section 3. Read the safety warnings at

the front of this manual before changing switch settings.

7.2.2 Do I have to calibrate a new controller?

7.2.3 Why doesn’t the displayed PV match the value on a

thermometer in the process?

Unless the thermometer and the sensor providing input to the controller are very

close to one another, their readings will not match in some applications, because

of temperature variations within the process.

7.2.4 I turned on the power; why doesn’t the controller light up?

If SafeChange is enabled, but the mainframe does not support SafeChange, the

controller will not work. Instructions for checking to see if a mainframe supports

SafeChange are in 3.2.
