I have a Durst AC 901, which I bought second hand and it is supposed to be in a working condition.

The components that I have is the AC 901 Head and the EPU 1200 power unit and the ECU 901 control unit.
I have not worked with it before.

According to the manual, when you switch on the enlarger, countdown starts from 60 seconds will take place on the density display.
After the countdown the 'Take-out-Negative' LED starts to flash and the customary bleep will be heard.

Basically it is booting up.

Well that is not happing, the ECU 901 control unit is not booting up with the above sequence.

- The only thing that shows on the ECU 901 control unit is the Exposure LED (23 (Number of ECU 901 lay out in manual)), the Enter LED (10), the Light on/off LED (24) and the W. Light LED (25).

- Secondly, there is no power that is going through to the AC 901 Head, it can be because the ECU 901 control unit is not booting properly up, I don't know.

Thanks for your advice.
