INTRODUCTION
1- GENERAL OPERATION
In normal operation, the compressor outlet pressure is controlled by the electronic interface as soon as the start button is
pressed or a remote start command is received. The interface will perform some safety checking before starting the
compressor, if no impediment condition is detected.
If there is any impediment condition, the compressor will not start and a message will be shown on the display. If there is
an operation impediment condition, the compressor will begin the start-up procedure, but the main motor will not work and the
compressor will go to standby mode and a message will be shown on the display. If load solicitation is present, according to
pressure values or by an external command, the motor will start. After the star/delta start time as well as the load delay
time (adjustable), the compressor will start loading. After the load delay time, the electronic interface will power the load
solenoid valve, which will open the inlet valve, enabling the compressor to operate in load mode. If the unload pressure is
reached, or an unload remote command is received, the load solenoid valve will be powered off and the compressor will work in
unload mode during the unload time (adjustable), before the main motor stops and the compressor goes into standby mode. The
compressor will load again if the pressure drops below the load lower limit and if the unload time is not finished. If the
compressor is already in standby mode, the main motor will start before loading and in this condition the load delay time will be
neglected.
When a main motor stop procedure starts (turn-off button is pressed or standby mode), the standby time (adjustable)
begins. If a start-up solicitation is made during the standby time, the compressor will go into standby mode until the standby
time is over. The same holds true if a load solicitation happens during the standby time. In compressors with enabled internal
pressure detection, a minimum start-up pressure can be adjusted to prevent that the compressor starts up with high pressures.
If the internal pressure doesn't drop below the lower limit two minutes after the end of the standby time, an error will be
generated and the compressor will shut down due to error.
After the compressor goes into unload mode, the reload timer (adjustable) is started to prevent compressor reload, this
time can be adjusted down to 1 second if necessary. The normal automatic operation of the compressor will be terminated
when the turn-off button is pressed, a remote stop command is received or if one of the compressor protections is activated.
When turned off manually, or by a remote command, the compressor will operate in unload mode and the stop time (adjustable)
begins. This time can be adjusted down to 1 second. Safety checking is performed continually, if a danger or a risk-of-burnout
condition is detected, the compressor will turn off automatically without applying the stop time, and an error message will be
shown on the display indicating the cause of the emergency shutdown. If an alarm condition is detected, a message will be
presented on the electronic interface display and the compressor will keep operating normally.
