3.f.2.3 Temperature Alarm (P4.2.3) (Cel/Fah):
If the screw temperature value increases above this parameter ‘s value, warning alarm is given. Warning LED and
temperature value on the screen blinks.
! Note: This value can be maximum 3
0
C below “P4.2.1 Upper Temperature Limit”.
3.f.2.4 Loading Temperature (P4.2.4) (Cel/Fah):
If the screw temperature decreases below this parameter ‘s value at start-up, the compressor won’t be loaded. When the
temperature increases above this value, the compressor works in normal operation.
3.f.3 Timing Parameters (P4.3):
3.f.3.1 Star / Delta Duration (P4.3.1) (sec):
The connection of the main motor will change from star to delta when this delay timer expires.
3.f.3.2 Delay for Start (P4.3.2) (seconds):
This delay is the time between that the compressor is started and that it is loaded. This parameter can be disabled by setting it
to “0”.
3.f.3.3 Reloading (P4.3.3) (sec):
This delay is the time between that the compressor is unloaded and it is reloaded. This parameter can be disabled by setting it
to “0”.
3.f.3.4 Auto Run Time (P4.3.4) (seconds):
If the power is interrupted while the compressor is running, when the mains is restored, the compressor is automatically
restarted after this delay timer expires. This parameter can be disabled by setting it to “0”.
3.f.3.5 Air Draining Time (P4.3.5) (seconds):
After the compressor stops, the air inside the screw is drained until this timer expires. The remaining time is displayed on the
screen and the compressor can not be started until this timer reaches zero. When the timer expires, the compressor enters into
Stopped mode.
3.f.3.6 Max. Starts/Hour (P4.3.6) :
When the number of start/stop ‘s in 1 hour is greater than or equal to this parameter, the Max. Starts/Hour is indicated. This
parameter can be disabled by setting it to “0”.
3.f.4 Service Hours (P4.4):
Service is due at the end of “Service Hours” (for changings & maintenances). Service remaining hours are calculated over
these service hours. (please refer to : Changings & Maintenance Remaining Hours)
! Note: To disable any of these parameters, please enter “000000”.
1. General Maintenance Hours (P4.4.1) (hour)
2. Bearing Maintenance Hours (P4.4.2) (hour)
3. Oil Changing Hours (P4.4.3) (hour)
4. Air Filter Changing Hours (P4.4.4) (hours)
5. Oil Filter Changing Hours (P4.4.5) (hours)
6. Separator Filter Changing Hours (P4.4.6) (hours)
