7.3 Exchange electronics
If the electronics module is defective, it can be replaced by the
user.
In Ex applications only one oscillator with respective Ex
approval may be used.
You find all information to the electronics exchange in the
operating instructions of the new oscillator.
In general, all oscillators of series SW60 can be interchanged.
If you want to use an oscillator with a different signal output,
you carry out the complete setup. You find the necessary,
suitable operating instruction on our homepage.
Note:
Keep in mind that enamelled instrument versions need special
electronics modules. These electronics modules are called
SW60E or SW60E1.
