Check com-munication between controller and AKA gateway.Medium Device is restarting The controller is restarting after flash updating of the softwareMedium IO module error There is a communication fault between the controller module andthe extension modules – the fault must be corrected as soon aspossibleLow MAN DI………. The output in question has been put in manual control mode via theAK-ST 500 service tool softwareLow MAN DO……… The output in question has been put in manual control mode via theAK-ST 500 service tool software
