4.2.1 Configuration menu items:
2. Sd – Star/delta time:
Time during which the main motor will run "in star" during the startup procedure before the transition to triangle.
• The star contactor is powered 200ms before the main contactor.
• The start-to-triangle transition time is set to 50ms.
2. Ad- Network address:
The RS 485 communication network address and the number of each compressor connected to the same network must be unique, star-
ting at 1 up to the number of compressors connected to the network.
2. LS - Load source:
a) The compressor will work using local pressure regulation (Pu and PL).
b) The compressor will answer to the RS485 remote management system pressure control.
The local pressure control (Pu and PL) is automatically restored if the RS485 communication is interrupted. When the RS485
communication is restored, the pressure control will automatically return to the remote system.
2. SS – Start source:
a) The compressor will start using the star key.
b) The compressor will start using a remote RS485 communication. The start key will be disabled.
Local and remote stop will always be enabled.
2.d5:rSS - Remote start and stop:
When the remote start and stop function is enabled, the compressor will perform a controlled stop, as if the stop
key was pressed, when digital input 5 (C5) is open.
The compressor will start normally when the remote start/stop input (C5) changes from open to closed state. If it
is closed, the input must be opened and closed again for a new remote startup. Local startup by start key will be
disabled.
2. d6: rLu – Remote load/un load:
The compressor may be made to enter load or relief in response to a 24 Vac signal (derived from the interface
feeding voltage). When this option is selected, the local pressure settings (Pu and PL) are ignored. The
compressor will be in load mode when the 24 Vac voltage is detected in the digital input 6 (C6) and in relief mode
when voltage is removed from C6. This function may be used for a control with pressure switch or remote
sequential activation.
The local pressure is still displayed; the high pressure alarm and the overpressure protection remain activated.
2.d6:PSr – Pressure switch mode:
In the pressure switch mode, the compressor may be made to enter load or relief in response to a 24 Vac signal (derived from the interfa-
ce feeding voltage). When this option is selected, the local pressure settings (Pu and PL) are ignored. The compressor will be in load mode
when the 24 Vac voltage is detected in the digital input 6 (C6) and in relief mode when voltage is removed from C6. This function may be
used for a control with pressure switch (PS).
