High Oil Differential Pressure Starting Shutdown Timer
This parameter is used to select the period of time that the
Oil Differential Pressure
may exceed the
High Oil
Differential Pressure Shutdown
parameter while the compressor is starting before a
High Oil Differential
Pressure Shutdown
is annunciated. The default value of this parameter is dependent on the compressor
manufacturer. This parameter is fixed on Grasso compressors and will not be visible. The value is measured
in seconds.
3.
High Oil Differential Pressure Running Shutdown Timer
This parameter is used to select the period of time that the
Oil Differential Pressure
may exceed the
High Oil
Differential Pressure Shutdown
parameter while the compressor is running before a
High Oil Differential
Pressure Shutdown
is annunciated. The default value of this parameter is dependent on the compressor
manufacturer. This parameter is fixed on Grasso compressors and will not be visible. The value is measured
in seconds.
4.
High Oil Differential Pressure Warning Offset
This parameter is used to set an offset value subtracted from the
High Oil Differential Pressure Shutdown
value. If the differential exceeds this calculated value, a
High Oil Differential Pressure Warning
will be annun-
ciated. The value is measured in the panel pressure units as selected on the
Panel Settings
screen.
5.
High Oil Differential Pressure Warning Timer
This parameter is used to select the period of time for which the
Oil Differential Pressure
may exceed the
calculated value for the
High Oil Differential Pressure Warning
before a
High Oil Differential Pressure Warn-
ing
is annunciated. The default value of this parameter is dependent on the compressor manufacturer. This
parameter is fixed on Grasso compressors and will not be visible. The value is measured in seconds.
6.
Low Oil Differential Pressure Shutdown
This parameter is used to select the minimum allowable differential in oil pressure. If the differential falls
below this value, a
Low Oil Differential Pressure Shutdown
will be annunciated. The default value of this
parameter is dependent on the compressor manufacturer. The value is measured in the panel pressure units
as selected on the
Panel Settings
screen.
7.
Low Oil Differential Pressure Starting Shutdown Timer
This parameter is used to select the period of time that the
Oil Differential Pressure
may fall below the
Low
Oil Differential Pressure Shutdown
parameter while the compressor is starting before a
Low Oil Differential
Pressure Shutdown
is annunciated. The default value of this parameter is dependent on the compressor
manufacturer. This parameter is fixed on Grasso compressors and will not be visible. The value is measured
in seconds.
8.
Low Oil Differential Pressure Running Shutdown Timer
This parameter is used to select the period of time that the
Oil Differential Pressure
may fall below the
Low
Oil Differential Pressure Shutdown
parameter while the compressor is running before a
Low Oil Differential
Pressure Shutdown’
is annunciated. The default value of this parameter is dependent on the compressor
manufacturer. This parameter is fixed on Grasso compressors and will not be visible. The value is measured
in seconds.
9.
Low Oil Differential Pressure Warning Offset
This parameter is used to set an offset value added to the
Low Oil Differential Pressure Shutdown
value. If
the differential falls below this calculated value, a
Low Oil Differential Pressure Warning
will be annunciated.
The value is measured in the panel pressure units as selected on the
Panel Settings
screen.
