DANGER
IT IS STRONGLY FORBIDDEN TO START REPAIRING A DEVICE WHICH IS CONNECTED TO AN AC NETWORK.
Fault codes of informational messages of the Fxxx format - events that occur during the operation of the controller and devices connected to it, which require the shutdown of the System until normal operating conditions, or until the restoration or replacement of faulty components.
In case of a Fault, the operation of the Computing Unit is stopped by the Internal Cooling System command with or without delay, depending on the emergency nature. The Internal Cooling System blocks the possibility of Computing unit manual control, information with a description and a fault code is provided on the display, and an audible alarm.
Alarm - codes of information messages of the Axxx format - events that occur during the operation of the controller and devices connected to it, requiring the attention of the User, but allowing further operation of the System.
If an Alarm occurs, the System continues to work, information with a description and an alarm code is displayed, and a warning sound signal is turned on.
In case of error: intermittent sound signal. It is possible to disable the sound by simultaneously holding both of the buttons for 2 seconds.
In case of an accident: continuous sound signal. It is disabled only when the Computing unit is completely turned off.
