3.f Service Parameters (P4)
Service parameters can be accessed only by entering service password or factory password at service password entry screen.
Service parameters are grouped under 10 headings . They are under ”P4 Service Settings”
3.f.1 Pressure Parameters (P4.1):
3.f.1.1 Stop Pressure (P4.1.1) (Bar/Psi):
If line pressure increases above this parameter ‘s value, trip alarm is given and the compressor is immediately stopped.
Alarm LED blinks.
! Note: This value can not be lower than 0,2 bar above “P4.1.2 Alarm Pressure”.
3.f.1.2 Alarm Pressure (P4.1.2) (Bar/Psi):
If the line pressure gets above this parameter ‘s value, warning alarm is indicated. The alarm LED blinks.
! Note: This value can be minimum 0,2 bar above “P3.2 Pressure Unload” and maximum 0,2 bar below “P4.1.1
Stop Pressure”
3.f.1.3 Screw Pressure Warning (P4.1.3) (Bar/Psi):
If the screw pressure increases above this parameter’s value, warning alarm is indicated. The alarm LED blinks.
3.f.1.4 Screw Pressure Alarm (P4.1.4) (Bar/Psi):
If the screw pressure increases above this parameter’s value, trip alarm is given and the compressor is immediately stopped.
Alarm LED blinks.
3.f.1.5 Delta Pressure Warning (P4.1.5) (Bar/Psi):
If the difference between the Line and Screw pressure increases above the value set by this parameter and the screw pressure
is above 4 Bar, warning alarm is indicated. The alarm LED blinks.
3.f.1.6 Delta Pressure Alarm (P4.1.6) (Bar/Psi):
If the difference between the Line and Screw pressure increases above the value set by this parameter and the screw pressure
is above 4 Bar, trip alarm is given and the compressor is immediately stopped. Alarm LED blinks.
3.f.1.7 Delta Pressure Delay (P4.1.7) (sec):
If the difference between the Line and Screw pressure increases above the value set by “P4.1.5 Delta Pressure
Warning” or “P4.1.6 Delta Pressure Alarm” for the time period determined by this period and the screw
pressure is above 4 Bar, the related alarm is activated. Alarm LED blinks. This parameter determines the time delay before
the alarm is indicated.
3.f.1.8 Screw Pressure Start Value (P4.1.8) (Bar/Psi):
While the “P5.13 Screw Pressure Active” parameter is set as YES, and during the initial start of the compressor if
this pressure sensor reads a value higher than “P4.1.8 Screw Pressure Start Value” parameter, the controller
will indicate an Air Evacuation Error.
3.f.2 Temperature Parameters (P4.2) (Cel/Fah):
3.f.2.1 Upper Temperature Limit (P4.2.1) (Cel/Fah):
If the screw temperature value increases above this parameter ‘s value, trip alarm is given and the compressor is immediately
stopped. Alarm LED blinks.
! Note: The minimum value for this parameter can be 3
0
C above “P4.2.3 Temperature Alarm”.
3.f.2.2 Lower Temperature Limit (P4.2.2) (Cel/Fah):
If screw temperature value decreases below this parameter ‘s value, trip alarm is given and the compressor does not run.
Alarm LED blinks.
