Fig. 7: Limit values
The SAB-Processor measures, shows and stores tem-
peratures, working hours and failures.
The display consists of a 2-digit measuring point indica-
tion (fig. 6/2) and a 3-digit indication for the correspond-
ing values (fig. 6/3). The data to be requested can be get
by short operation of the data input/output key (fig. 6/1).
The SAB-Processor has 4 temperature inputs:
1. Pressure dew point
2. Refrigerant suction gas temperature
3. Compressed air inlet temperature
4. Ambient temperature
Incoming measured values will be compared and the
resulting average values will be processed. Rapid changes
of the incoming measured values on steady higher or
lower value resp. will be checked. If the value changes
are too high it is recognized as measuring failure.
2 limit values are provided for each temperature between
which the temperatures must be during normal operation.
After starting the CA-dryer all errors will be suppressed
for 15 minutes.
