9.3. List of versions
Version no. Description
1.0.2.3 Some Display freeze problems experienced in the previous released versions
have been solved.
This version, released and distributed in February 2008, has replaced all
previous versions on all, up to then, delivered Unisab III.
1.0.3.1 Modbus TCP communication stability against MBE and other Modbus drivers
have been further improved. In some plants using external Modbus TCP
communication the display could still freeze.
It was still possible in some situations to experience display freeze (or black/
white screen) in the user interface when you operated the keyboard. These
problems should now all have been solved.
A false oil pump error, which could show up at compressor stop, has been
solved.
The high Shutdown limit for oil separator temperature is now removed, and
the high alarm limit is raised to 100°C.
A new picture showing Multisab status information for this compressor itself
has been added. See engineering manual for description.
The Security handling when operating in remote manual control has been
improved. See engineering manual for description.
A number of dedicated SabCube control and communication functions have
been added.
1.0.4.0 Control and supervision for SABCube compressor types SAB 109, SAB 133,
SAB 159 have been added.
Modbus RTU communication with the SABCube frequency drive and a VSD set-
up menu has been added.
The set point for oil separator temperature has been raised from 20ËšC to
50ËšC.
A Quick setup menu has been added under Setup/Configuration.
A user definable Modbus TCP data block is now available.
If drive/display is set to kW it will always be reset to Amp if/when Unisab is
restarted or if making a factory reset.
Multisab could fail - the system was not updated and the regulation master
would not change if the start number was changed in one of the compressors
or if one of the compressors was in limitation. This situation could be avoided
by changing the system number to one not used and then back which would
update the system to the correct master. This problem has been solved.
