Remote Control Value Units
This parameter is used to select the units that will be used to express the value measured at the Remote
Control Value analog input. The options are:
• Pressure
• Temperature
Hint!
The selected Control Signal must match this setting.
6. Maximum Capacity Slide To Allow Start Override
For GEA Grasso Small and Medium compressors, if the compressor capacity slide position remains above
the
Maximum Capacity Slide To Allow Start parameter during the period of time dictated by the Capacity
Slide Failed to Unload Shutdown Timer , the panel will compare the slide position to this value. If the capacity
slide position is greater than this value for the duration of the Capacity Slide Failed to Unload Shutdown
Timer , a shutdown will be issued. The value is measured in percent.
7. Maximum Capacity Slide To Allow Start
This parameter is used to select the maximum allowable position of the capacity slide when the compressor
is instructed to start. If the capacity slide position is above this parameter when a start signal is received, the
compressor will unload until the slide position has dropped below the parameter before allowing the com-
pressor to start. The compressor will also unload to this position after the compressor is stopped. The value
is measured in percent.
8. Capacity Slide Failed to Unload Shutdown Timer
This parameter is used to select the amount of time the panel will wait for the compressor to unload, either
before starting or after stopping, before a
Capacity Slide Failed to Unload Shutdown will be annunciated.
The value is measured in seconds.
9.
Capacity Control Delay
This parameter is used to select the period of time that will elapse between the compressor starting and
capacity control being enabled. The value is measured in seconds.
10. Load Limitation Delay
This parameter is used to select the period of time for which the compressor will wait after a limitation condi-
tion is cleared before beginning to load. The value is measured in seconds.
11. Sequencer Overwrite Local Capacity Parameters
This parameter is used to select whether the local capacity control parameters may be overwritten by param-
eters from an external sequencer.
12. Zero Load Shutdown Timer
This parameter is used to select the period of time that the capacity slide position may remain at the zero
load percentage before a shutdown condition will be annunciated. The value is measured in seconds.
13.
Swing Compressor Control
This parameter is used to select the current function of the compressor. The parameter will only be visible if
the compressor application is set to
Swing in the configuration. The options are:
• Low Stage
• High Stage
