AZD-DC Driver Power LED is lit RED.

By accident the AZD-DC Driver got 220V AC on DIN9 port.

The driver Power LED went into RED (b.t.w. the meaning of steady RED is not mentioned in the Driver Operating Manual).
I can imagine there went something wrong in the driver.

Normally this DIN port is opto-isolated from the driver main board, but the RED power LED light shows the driver stills has some power problems. MODbus RS485 does not respond any more, also there is no COM port for the MEXE02 any more.

Question 1: What is the isolation voltage to the driver ground?

To solve the problem, Is it possible
1. to replace replace the driver board (EB6333-9) ?
2. or is it required to service the full AZD-CD driver module ?
3. or should I have to buy a brand new driver module?
Question 2: Which is the most appropriate way to have the module be repaired?

Hello,

The solid red PWR/ALM LED would be a CPU error. This is referenced on page 461 of the link below. Unfortunately for this alarm you would have to replace the driver as it cannot be repaired being a CPU malfunction. The CN5 I/O connector is only meant to be used with DC voltage up to 24 VDC.
