Corresponding to the set limit values, at critical opera-
tion phases an alarm, and at prohibited operation condi-
tions a failure report is triggered by the processor´s
monitoring system (see 5.2.2).
The SAB-service unit permits changes of limit values,
simple data input and output as well as the recording of
all data for service purposes and documentation.
All data can be printed via the SAB-service unit by means
of a printer.
The condensate drain automatically drains the conden-
sate. A minimum pressure of 30 psig is required for safe
operation.
Once the container has filled with condensate, so that
the capacitive level sensor emits a signal, the internal
solenoid valve opens and the condensate is forced by
the working pressure into the discharge pipe.
The condensate drain electronic system ensures the clos-
ing of the outlet opening before any compressed air can
escape.

2 Manual draining (operate button for max. 30 sek.)
3 Failure (LED blinks, see 5.2.3)
At standstill or very small volume flow of the CA-dryer, a
time-controlled solenoid valve avoids the collection of
condensate in the inlet pipe to the water separator.
Furthermore the solenoid valve controls the desludging
of the heat exchanger.
The solenoid valve is accessible after removing the right
side plate (fig. 4/9).
