This alarm appears on the display, the machine is stopped:

STRATER MALFUNTION DETECTED

and Replace, relay board, digital board, power supply and rectifier diode.

I have another point to check?

you will have to manually change the real time clock?

thanks

Hi
it would seem the vsd you have has a power supply problem .
check all the flat cables and connections
when replacing the main card the clock will need to be reset .
this seems like a very vague fault message!!
good luck

Check the electronic protection of the compressor motor, it is connected in series to the coil of the power contactors and causes alarm of missed departure.

Hi
check your contacs that feed back an input to the controller on contactors status.
i would also heck your relay board.
good luck

I changed the following parts:

relay board
power supply
diode rectifier
digital input
CM2
the RTC would have some relation with this problem?
