The compressor is going to stop after the delay timer in parameter P3.5 To Stop Delay” expires. Remaining
time is displayed on the right of the lower row.
2.b.3 STARTING :
The compressor is going to start after the delay timer in parameter P3.8 To
Start Delay” expires. The remaining time is displayed on the right of the
lower row. When the delay timer expires, main contactor and star contactor are
energized.
Note: Star contactor is energized at 100 ms after the main contactor is energized.
2.b.4 MOTOR DRIVING :
When the delay timer in parameter “P4.3.1 Y-Delta Rising” expires,
the star contactor will be deenergized and delta contactor will be energized.
Remaining time is displayed on the right of the lower row.
2.b.5 WORKING ON UNLOAD :
This indicates that the compressor is running on unload. The load solenoid is
deenergized. After the delay timer in parameter “P4.3.2 Getting Load”,
the compressor starts running on load.
While the compressor is running on unload, when the delay timer in parameter
“P3.3 Wait on Unload”, the mode of the compressor is changed to
AUTOWAITING. The remaining time of “Waiting on Unload” is displayed on
the right of the lower row. This is valid for AUTOMATIC mode only(“P3.1-
Operation mode” parameter is set as “automatic”).
The compressor runs on no load when the airend temperature is less than the
temperature set in parameter “P4.2.4 To Load Temperature” . In this
case, icon on the left of the temperature blinks every 1 second.
2.b.6 RUNNING ON LOAD :
This indicates that the load solenoid is energized and running on load.
2.b.7 ON AUTOWAITING :
In this mode, the main contactor and delta contactor of the compressor
have been de-energized and the main motor has stopped. Green LED
blinks with long intervals. If there is a pressure transducer and the air
pressure is below the pressure in parameter “P3.4 Pressure Load”,
the compressor gets out of “Autowaiting” mode and gets into “Starting” mode. If there is a pressure switch, when
the switch is “closed”, the compressor gets out of “Starting” mode and gets into “Autowaiting” mode.
