The Digital Multi Control panel (DMC) is designed to work with all Multi/Quattro. This includes stand-alone, parallel, and 2-3 phase configurations. Connecting the DMC to your system is simple, in most cases just connecting the DMC with an RJ45 cable is sufficient and no extra set-up handling is required.
VE.Bus system with 1 AC source
Setup for such a system is easy: Just connect the DMC to the VE. bus system and the DMC will automatically adapt to the current system.
No parameters need to be changed in the DMC unless you want to limit the maximum current the operator can set. In that case, you only need to adapt the "Upper shore limit for AC input 1" setting. Refer to chapter 6 for a description of how to do this.
VE.Bus system with 2 AC sources
There are several ways to build a VE.Bus system with 2 AC sources. Refer to the appropriate sub-paragraph for your installation
Extended VE.Bus system with Multis
A system with more than 1 AC input can be built with normal Multis. The extended VE.Bus functionality is used for this purpose. This functionality comes available when a dongle is connected to the system. The system must then be configured with the "VE.Bus System Configurator" tool.
From the DMC point of view, there is no difference between a system build with Quattro's and a
system build with Multis. So read on with paragraph 2.2.2. Note that, by using VeConfigure2, it is
possible to determine whether or not an AC input shore limit can be overruled by the remote
panel.
VE.Bus system built with Quattro's
If your system is built with one or more Quattro's the installation of the DMC is straight-forward. Just connect the DMC to the VE.Bus system (see paragraph 4.1) and the DMC will automatically adapt to the current system.
Most likely you do not need to change any settings in the DMC.
In a Quattro, the AC1 input has always priority over the AC2 input. The default setting in a Quattro
is that the AC2 shore current can be overruled by the remote panel and the AC1 limit is fixed.
(This can be changed with VeConfigure2)
A common practice is that a generator is connected to AC1 and shore power to AC2. As long as the generator is running the Quattro's will use the generator. The DMC will display in that case and turning the knob on the DMC will not have any influence. When the generator is stopped and shore power is applied, the Quattro's will switch to the shore power. Now the DMC will continuously toggle the display between and the current shore limit set point. Turning the knob will now change the shore limit set point in the Quattro's. If you want to limit the maximum current the operator can set you can change the "Upper shore limit for AC input 2" parameter. Refer to paragraph 6 for a description of how to do this.
Description of the Digital Multi Control GX panel
The DMC is a remote panel designed to work with all Multis/Quattro's and Multi/Quattro systems. This includes stand-alone, parallel, and 2-3 phase configurations. Both VE.Bus and non VE.Bus systems are supported. With the DMC a separate shore current and generator current can be set. When used in an extended VE.Bus system one can even set up to 4 different shore currents. For VE.Bus systems, the DMC will automatically adapt the adjustable range to match with the connected system.
