and some Stal types equipped with oil level switch, the Oil level check is used as start permis-
sion and oil heater ‘switch on’ permission.
10: Oil low alarm coefficient
This parameter is used for SABflex and SABCube oil pressure calculation, see Table 8: Meas-
ured and calculated pressure levels - screw compressors.
11: Oil unload coefficient
This fixed parameter is used for SAB 157 HR to unload the plug valve to secure the lubricating
oil pressure at start-up. See subsection 3.2.3. Special limiters, Plug valve limiters (SAB
157HR).
12: Oil load coefficient
This fixed parameter is used for SAB 157HR to load the plug valve at start-up. See subsection
3.2.3. Special limiters, Plug valve limiters (SAB 157HR).
