Version no. Description

For SAB 157HR, the "Oil pump safety" logic did not work properly. The dis-

played pump pressure did not update and alarm and shutdown functionalities

were not working. This has now been corrected.

For SABflex, the calibration of Suction internal pressure, AI P6, was not possi-

ble. A new calibration value Internal Adjustm. has been added as parameter

#5 in the calibration menu.

For SABflex, the capacity increase output DO10 was flickering when Danfoss

communication was chosen (Drive Com = DA), and the capacity was in 100%.

This has now been corrected.

For SABflex, when Oil pump was configured as demand pump, the oil pump

was started 1 second before the compressor motor start command was is-

sued. This has now been corrected, i.e. the oil pump does not start before the

compressor is running.

For SABflex, the Separator temperature was missing in the Oil picture. This

has now been corrected.

For SABflex, the Oil circuit pressure high alarm, the Oil circuit pressure high

shutdown and the Critical oil circuit high shutdown have been implemented.
