dear members:
i have problem in elau pacdrive mc4,some times when power on drive error red led blink and some times when power on and off for three or four times the error led turn off and no error.have a someone solution for this problem?

its likely the 'blender' module is on its way out, there is no fix other than replace MC4 module and send the other for repair


Best of luck to you

your mc4 need reprogramming flash ic,you must find the same working mc4 and read flash then program dump file to your mc4 that have problem.

how is the IC flashed? with the Diag connection of the sercos card or directly to the pin of the Flash IC
