User Manual R0.2
Screw Pressure High (HIGH SCREW):
The device received the run command and the screw pressure value is higher than the
"P007 Minimum Screw Pressure " value, it is waiting for the pressure to decrease below this value. When the
pressure drops below this value, the running process continues.
Motor is Running in Star Position (Motor Start):
The device received a run command, star and main contactor are active and the device
is waiting for the end of the time entered to the "P028 Star Running time" parameter.
Preheat Idle Operation (PREHEAT OFLD):
The device received run command and since the screw temperature is low, it is in the
preheat mode and air solenoid is passive. See "Application Note Preheat". Related parameters are “P126
Preheat
Limit
” and “P032 Preheat idle time”. Main Contactor and Delta Contactor are active.
Preheat Running on Load (PREHEAT LOAD):
The device received run command and since the screw temperature is low, it is in the
preheat mode and air solenoid is active. See "Ap
plication Note Preheat". Related parameters are “P126
Preheat
Limit
” and “P031 Preheat on Load time”. Main Contactor and Delta Contactor are active.
Idle Run (IDLE):
The device runs the compressor in idle mode. The solenoid valve is passive and the
compressor does not produce air. Seen in two different positions.
•
First position, on initial run command, during “P024 idle run time” after Motor Start time.
•
Second position, Compressor line pressure passed the "P002 Idle Pressure " parameter and it waits for the
time entered to the "P026 Auto Waiting Delay" parameter to expire. The device runs the compressor in idle mode.
The solenoid valve is passive and the compressor does not produce air. If the line pressure does not go below “P003
Onload Pressure
”
before the end of this period, the compressor stops.
Running on Load (ON LOAD):
The device received a run command, the solenoid valve is active and the compressor is
producing air. The compressor line pressure is below the value entered to the "P002 Idle Pressure "parameter.
Switching to Load (PASS ONLOAD):
The pressure value on the device exceeded the value entered to the "P002 Idle
Pressure "parameter, the pressure decreased to a level that is below the value entered to the "P003 Onload
Pressure" parameter, and the device waits for the value entered to the "P25 Pass Again Onload Time" parameter to
expire.
