This setting will overrule the "unload" pressure setting (P4 of user menu) when the configuration becomes active.
The sub-item "load pressure" (5) will be selected. Press UP or DOWN to adjust the setting, and the press ENTER; the screen will return to
the menu list.
Note: all the pressure scheduling adjustments are kept in chronological order. When a configuration is inserted, it changes the position on
the list automatically; this will be shown clearly.
To force the compressor to go into standby status, adjust the unload pressure setting to 0 (zero). The item for load pressure setting will be
skipped in this case.
To adjust a pressure scheduling setting:
Select the pressure scheduling item that requires adjustment and press ENTER. Follow the same procedure to adjust a new pressure sche-
dule, adjust the sub-items when necessary. If a sub-item requires no adjustment, press ENTER to move to the following sub-item.
To erase a pressure scheduling setting:
Navigate to the pressure scheduling item and press ENTER. Press DOWN to adjust the item "day of week" to 0 (zero) and then press ENTER.
All remaining sub-item settings will be automatically reset to zero and the configuration will be deleted from the pressure scheduling list.
The screen will go back to menu list.
The setting of the value for the unload pressure is limited to 0,2bar below the limit set for the line pressure alarm. If the limit for
the line pressure alarm is adjusted to a higher value, it's possible that pressures set higher will result in "Alarm", "Shutdown",
or "General Failure" fault conditions.
4.4.13 – Priority of the Pressure Control Sources
The pressure control can be done by a certain number of sources, internal or remote ones. Each potential source has a different priority
from others. The priority diagram shows which pressure control mode the interface will use in all the selections of potential configurations,
conditions of remote connection or failure modes.
The digital input to enable remote load (mode 16) has priority over all pressure control sources. If, for example, the line control RS485 is
selected as primary source (8), and the communications are interrupted, the interface will automatically restore the pressure control to
network RS485 (8).
There are 28 pressure scheduling configurations available; they are the items 03 to 30 of page
P11. Each item of the pressure scheduling indicates the "Day of week" and the "time":
D.HH:MM (1.06:30)
D (1) Day of week (1=Monday to 7=Sunday)
HH (06) Hour of day (24 Hours)
MM (30) Minutes.
