Do not think, that CTL23 is faulty. When CTL23 doesn't work then minilab doesn't work at all. Your error is about not correct 12V power supply voltage on LDD23 CPU. Might be, that really you have this voltage and just control circuit doesn't detect it properly. Error can cause fault on LDD23. 12V is on board input, but CPU doesn't see it properly. Check all LFDD23 fuses. If they are good - replace LDD23.
