The customer of these CA-dryers has the possibility to
adapt the upper error value of the pressure dew point to
the company´s needs, if necessary.
The actual status of the DIP-switches is read during the
program start only, i.e., after each change of the switch
position, a power disconnection must be executed
Switches 1 and 2 are used for the upper switching point
of the pressure dew point , switches 3 serves for chang-
ing between °C and °F . Switch 4 must not be changed in
its position.
All 10 minutes the temperatures are read into and up-
dated in a memory.
Additionally date and time of all values are stored, too.
So the temperatures of the last 24 hours can be followed
up.
During normal operation the display indicates the dew
point temperature. Following values can be recalled con-
secutively when the data input and output keys are
pressed:
1. Pressure dew point
(compressed air)
2. Suction gas temperature (refrigerant compressor)
3. Inlet temperature
(compressed air)
4. Ambient temperature

(indicated value x 100)
If key (fig. 6) is not operated, the display shows again the
pressure dew point after about 45 seconds .
