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 20˚C to 50˚C.
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 com-
pressors 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.
