This input are not used.
A IN 6 T-BRINE INLET
Brine temperature at the inlet. 4-20 mA corresponds to -50 to +50°C. If no signal is given at the input, -
75°C will be displayed.
A IN 5 T-BRINE OUTL.
If compressor regulation is to be based on brine temperature, the measurement of temperature must be
registered at this input. 4-20 mA corresponds to -50 to +50°C. If no signal is given at the input, -75°C
will be displayed.
A IN 4 P-OIL AT FILTER
On certain versions of compressor units, there are four pressure transmitters instead of three. The extra
pressure transmitter is placed in the oil line immediately ahead of the point where oil enters the oil
filter. It registers pressure in bars. On machines without the extra pressure transmitter, -5.25 bar is
displayed in the field.

R IN 7 CAPACITY SLICE POS.
A potentiometer under the cover nearest the compressor input shaft or at the end of the cylinder
registrers a resistance value between 0 and 2200 ohm depending on where the capacity slide is
positioned. The measured resistance can be read off here. If an hermetic transmitter with inductive
registration is used, the value is converted to the value corresponding to a registration of a resistance
value.
R IN 6 VOLUME SLIDE POS.
A potentiometer under the cover farthest away from compressor input shaft registers a resistance value
between 0 and 2200 ohm depending on where the volume slide is positioned. The measured resistance
can be read off here. If an hermetic transmitter with inductive registration is used, the value is
converted to the value corresponding to at registration of a resistance value.
