6.4. Configuration
Unisab III can be configured to a number of different functions depending on compressor
type, refrigerant etc. Some settings are factory set but it is always necessary to make some
final settings before start-up.
The immediate configuration can always be checked during operation but if one or more con-
figuration points should be changed, always stop the compressor and activate the emer-
gency stop while making the changes.
After changing the configuration, the first press on may initiate the Unisab III software re-
set to re-initialise the database. Within a few seconds after resetting, Unisab III will show the
Favourites/Default picture. Now release the emergency stop.
The configuration points where a change will initiate a software reset to re-initialise the data-
base to factory settings are marked with ** in Table 42 and Table 43. The configuration
points where a change will initiate a software restart, but no reset to factory settings, are
marked with * in Table 42 and Table 43. The use of each function is marked with 1) for recip-
rocating and 2) for screw compressors.
Table 42 and Table 43 include a description of each configuration point as well as possible
choices with reference to the position numbers in the previous pictures.
