Start-up procedure:
If utility mains voltages and frequency is between set limits and the phase order is correct, the the LINE
led will turn on. The compressor can run only when the LINE led is on. Otherwise it cannot be run by any
means.
The RUN mode is selected by depressing the RUN pushbutton or by setting the REMOTE START
signal (if enabled). At this stage the compressor will run only when the output pressure falls below the
E.05 Start Pressure (or when the pressure switch closes).
Before the compressor runs, the STAR relay will be activated. After the expiration of E.15 Delay
Between Relays Timer the MAIN relay will be active. Thus the motor will start-up in STAR configuration.
After the expiration of E.22 Star Timer the STAR relay will release. After the expiration of E.23 Star Delta
Timer the DELTA relay will be active.
After the expiration of E.24 Time Before Load, the LOAD relay will become active and the compressor
starts producing compressed air.
Unloading and reloading of the compressor:
When the output pressure reaches E.04 Stop Pressure limit (or the pressure switch opens) the load
relay will release and the motor will run off-load during E.25 Unload Timer. If the pressure falls below the
E.05 Start Pressure before expiration of the timer, then the LOAD relay will be activated again.
Stopping and restarting following output pressure:
If the output pressure stays over the E.05 Start Pressure during E.25 Unload Timer, then the DELTA
relay relases. After E.15 Delay Between Relays the MAIN relay releases and the compressor stops.
In this position the RUN led is flashing.
The maximum number of start cycles that the compressor is allowed to perform in 1 hour is defined by the
F.01 Max Starts per Hour program parameter.
If the maximum number of starts is reached, then following stop cycles will be skipped until the expiration
of 1 hour period.
