The current settings (AC current limitation and charging current) are multiplied by the number of devices. However, the AC
current limitation setting when using a remote panel will always correspond to the value indicated on the panel and should not
be multiplied by the number of devices.
Example: 7kVA parallel system
- If an AC-in-1 current limitation of 20A is set on the master and the system consists of three devices, then the effective system
current limitation for AC-in-1 is equal to 3 x 20 = 60A (maximum input power 3 x20 x 120 = 7,2kVA).
- If a 30A panel is connected to the master, the system current limitation for AC-in-2 is adjustable to a maximum of 30A,
regardless of the number of devices.
- If the charging current on the master is set to 100% (70A for a Quattro 24/3000/70) and the system consists of three devices,
then the effective system charging current is equal to 3 x 70 = 210A.
The settings according to this example (7.2kVA parallel system) are as follows:
Master
DS-8 AC-in-1 (3 x 20 = 60A)
DS-7 AC-in-1 (3 x 20 = 60A)
DS-6 AC-in-1 (3 x 20 = 60A)
DS-5 AC-in-2 na (30A panel)
DS-4 Charging current 3x70A
DS-3 Charging current 3x70A
DS-2 Master
DS-1 Master
To store the settings after the required values have been set: press the 'Up' button of the master for 2 seconds (upper button
to the right of the DIP switches, see appendix A, position K). The overload and low-battery LEDs will flash to indicate
acceptance of the settings.
We recommend making a note of the settings, and filing this information in a safe place.
The DIP switches can now be used to apply the remaining settings (step 2).
