8 Fault elimination
Important! Most operational malfunctions are not caused by faulty equipment but rather by improper
installation or disregarding of planning guidelines. Therefore, a complete fault diagnosis always in -
volves a thorough examination of the entire system. Often, the steam hose connection has not been
properly executed, or the fault lies with the humidity control system.
8.1 Fault indication
In case of malfunction during operation, the unit control checks whether there is a temporary prob -
lem or whether it can resolve the problem by taking necessary measures. Such malfunctions are
not indicated in the normal operation mode. However an appropriate error code with the status
“Warning” is generated.
Note: If the cause of the malfunction disappears of its own accord or if the controls can repair the
malfunction, the alarm will automatically reset.
If the control, after several attempts, fails to solve the problem (number of attempts depends on the
type of malfunction) or if the problem obstructs further operation, the heating voltage is interrupted
via the main contactor. The red LED lights in normal operation mode and an appropriate error
code with the status “Error” is generated.
The error code can be queried in the info mode . Press drain/info key at least 3 seconds to
enter the info mode. In the info mode the number of flashes of the red LED indicates the decade
of the error code while the number of flashes of the yellow LED indicates the digit of the error code
(refer to chapter 6.3.1 for further information regarding the info mode).
Examples:
