Safety Failure Message
Percent Volume Fail – This message will appear if the percent volume reading exceeds 300% or
goes below –15%.
Lo Control Temperature Fail – This message will appear when the Process Control Temperature falls
below the safety setting of the Lo Control Temperature Trip Setpoint. In
addition, this message will appear when the Process Control Temperature
rises above 300 degrees F, indicating an open RTD.
Lo Start Oil Pressure Fail – This message will appear with the Prelub Oil Pressure (Manifold minus
Discharge) has remained below the Prelub Oil Pressure Reset setpoint.
The Prelub Oil Pressure must be above the Prelub Oil Pressure for a time
period of the Minimum Compressor Prelub time. It will continue to try to
do this for a time period of the Prelub Oil Pump Time Limit. When the
Prelub Oil Pressure fails to achieve this, then the failure message will
occur.
Lo Oil Pressure Fail – This message will appear when the Running Oil Pressure (Manifold minus
Suction) has remained below the low Oil Pressure Reset setpoint when the
Oil Pressure Bypass at Compressor Start timer times out. This message
will also appear when the Runnning Oil Pressure falls below the Low Oil
Pressure trip setpoint after the Oil Pressure Bypass at Compressor Start
timer times out.
Lo Oil Injection Temp Fail – This message will appear when the Oil Injection temperature falls below
the Low Oil Injection Temperature trip setpoint. This message will also
appear when the Oil Injection temperature fails to rise above the Low Oil
Injection Temperature reset setpoint after the Low Oil Injection Temp
Bypass timer times out.
Hi Oil Injection Temp Fail – This message will appear when the Oil Injection temperature rises above
the High Oil Injection Temperature trip setpoint.
Manifold Pressure Fail – This message will appear with the manifold pressure rises above 300 PSI
or falls below 30” Hg.
Filter Inlet Pressure Fail – This message will appear with the manifold pressure rises above 300 PSI
or falls below 30” Hg.
Start Filter Diff Press Fail – This message will appear if the Filter Differential pressure rises above the
High Fltr Diff Press – Start setpoint before the Filter Differential Pressure
Safety Changeover timer times out.
