What can we help you with?
My SIGMA 2 Load Bank Control Module is showing “n” code – “Load Bank firmware upgrade in progress” on the LED status display. What does that mean?
Your SIGMA 2 Load Bank Control Module needs to be returned to us for inspection and/or repair.
Please go to our support page and fill in your details and a member of our support team will be in touch to organize the return of the module.
