Set-up
10: Take over (reciprocating compressors)
No
Yes
Select Yes if UniSAB III is configured as a reciprocating compressor, operates in a combined plant of re-
ciprocating and screw compressors and the Take over/transfer function in Multisab is required.
11: COP active
No
Yes
Select Yes if UniSAB III is fitted with a function for COP measuring (Coefficient Of Performance, i. e.
cooling efficiency of compressor). COP measuring requires a flow measuring device as well as a motor
efficiency measuring device. See also UniSAB III COP Manual. Select No if UniSAB III is not used for
COP measuring.
12: Chiller/Heat pump
No
Yes
Select Yes to use the following build-in functions for chiller control. See section 3.6 Compressor control -
chiller functions for a detailed description.
Select Yes to enable the measurement and supervision of the process in temperature input. The proc-
ess in temperature will then be displayed in Control values/Process Temp/Values. See subsection 3.6.7
Flow condenser (ChillPAC/PAC - optional).
Always select No if you do not use chiller functions. See section 3.6 Compressor control - chiller func-
tions for a detailed description.
When chiller operation is set to Yes, the following configuration points, 13 to 21, will show up:
13. Process out temp.
No
Yes
Select Yes (default) to monitor and use the Process out temperature function. See subsection 3.6 Com-
pressor control - chiller functions.
Select No to disable the Process out temperature function, which means that the alarm, shutdown and
limiter functions will be disabled.
14. Process in temp.
No
Yes
Select Yes to monitor and use the Process in temperature function. See subsection 3.6 Compressor
control - chiller functions
Select No (default) to disable the Process in temperature function, which means that the alarm and shut-
down functions will be disabled.
15: Oil return sep.
No
Yes
Select Yes to use the oil return from separator function. See subsection 3.6.3 Oil return from oil separa-
tor (ChillPAC).
