Fault
Operational states where further operation is not possible, or where further
operation would damage the system are indicated with a fault message, ad-
ditionally the fault indicator LED below the touch panel will lights up red. If
such a malfunction occurs, the steam production of the Condair RS will be
stopped automatically.
By pressing on the maintenance and malfunction indication eld in the standard operating display the
error list shown with all active warning and fault messages. By pressing on the corresponding Warning or
Fault entry additional information regarding the malfunction are displayed (see display on the far-right).
7.3 Malfunction list
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 involves a thorough
examination of the entire system (e.g. hose connections, humidity control system, etc.).
