8.8.3 Refrigerated dryer alarm – Compressed air quality has priority
In the event of a refrigerated dryer alarm, the SIGMA CONTROL 2 shuts the machine down.
No compressed air will be delivered.
As compressed air quality (i.e. dried compressed air) is crucial, an authorized KAESER service
representative must be contacted immediately.
The authorized KAESER service representative eliminates the fault and executes a reset.
Precondition The operator decides: Compressed air quality has priority over compressed air supply
1. The machine remains shut down because the required compressed air quality can no longer
be delivered.
2. Contact an authorized KAESER service representative immediately.
8.8.3.1 Fault mode without refrigerated dryer
Higher residual moisture in the compressed air
Corrosion due to higher residual moisture in the compressed air.
➤ Carefully assess using the option “Fault mode without refrigerated dryer” with respect to
the requirements of the operator.
In order to ensure continued compressed air supply for a defined period of time, the operator can
activate the Error operation without RD function. In this case, the compressed air quality (dried
compressed air) is compromised. The warning message 0069 Error operation without RD
→ Call service! will be displayed. The warning message 0069 will remain active for the duration of
operation in fault mode.
Precondition The operator decides that, for a limited period of time, the compressed air supply has priority over
compressed air quality
