Version no. Description
1.0.9.8 It has been reported from the field that a file write access could fail which
would initiate a repair routine in Unisab III and as part of this procedure Uni-
sab III could reset. This has now been corrected.
1.0.9.9 It has been observed from sites with iRIS installation that Unisab III would
sometimes restart when sending an e-mail to the mail server if the communi-
cation was bad due to e.g. low signal strength or unstable connection. This
has now been corrected.
It has been observed from some sites that Unisab III would sometimes restart
and finally end up being “locked”, i.e. not being able to restart. The cause is
found to be a very large Error.log file which would occupy the flash memory
thus preventing Unisab III from operating correctly. This problem has been
corrected.
As an extra security, version 1.0.9.9 is designed to erase the Error log file af-
ter the software installation or prior to an Error log write operation if it is de-
tected to be larger than 10 Kbyte.
For screw compressors the timer for Fan after run can now be adjusted be-
tween 0 and 1200 seconds. The default setting is 60 seconds.
After 5,000 hours for screw and 7,500 hours for reciprocating compressors a
Service alarm A will occur. With the present Service Notice maintenance pro-
gram this Service alarm A cannot be acknowledged with normal Superuser
password but must be acknowledged with Supervisor password. Both the
Service alarm A and the Service alarm B functionalities have been completely
disabled.
