Oil Pressure Safety Bypass timer times out.
Low Oil Injection Temp Trip
• This message will appear when the Oil Injection tem-
perature 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.
High Oil Injection Temp Trip
• This message will appear when the Oil Injection
temperature rises above the High Oil Injection
Temperature trip setpoint.
High Filter Differential Trip
• 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.
High Filter Differential Trip
• This message will appear if the Filter Differential
pressure rises above the High Fltr Diff Press Run
setpoint after the Filter Differential Pressure Safety
Changeover timer times out.
High Motor Current Trip
• This message will appear if the motor amperage rises
above the Hi Motor Amps trip setpoint.
Compressor Interlock Trip
• This message will appear if the Motor Auxiliary con-
tact fails to close before the Compressor Starter
Auxiliary Contact Bypass timer times out. Refer to
wiring diagram.
High Level Shutdown Trip
• This message will appear when power is removed
from the input module that is designated as “Auxiliary
#1 Safety” Refer to wiring diagram.
False Start
• This message appears when the compressor stops
and the motor auxiliary contact fails to open. The
message will also appear if the compressor shuts
down and the amperage is 20% of the maximum amp
setting, indicating that the starter is still energized.
Low Oil Level Trip
• This message appears when power is removed from
the designated input module, refer to wiring dia-
gram. This safety will activate only after the oil level
has been low for the time period defi ned by the “Low
Oil Separator Safety Trip Delay” timer.
