Digital multi control available at
Livestainable. The Digital Multi Control is used to remotely view and adjust AC input currents, and turn on and off the Multi or Quattro. It is designed to integrate cleanly with your boat, vehicle, or house system control panel.
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.
Generator support The DMC provides a means to change the AC input current limit when the AC source is switched externally from shore to generator. Normally the DMC will send the shore current setpoint as determined by the knob to the
connected devices. If however the terminals of the screw connector on the backside of the DMC are short-circuited the DMC sends a preconfigured shore limit to the connected devices. This preconfigured limit is generally used for a generator. The display on the DMC will therefore show.
The two terminals of the screw connector are to be connected to an externally controlled switch.
Normally spoken this will be an auxiliary relay of an external transfer switch.
Connecting VE. Bus devices Using the DMC with VE. Bus devices are straightforward. Just connect the DMC to the system. The maximum/minimum shore currents which can be set are automatically adapted to the system.
This means that:
- Connecting the DMC to one Multi with 16A feed through capacity will limit the maximum shore
setting to 16A.
- Connecting the DMC to five of these Multis in parallel will result in 80A as the maximum shore limit.
(If needed, an upper limit can be set to prevent the operator from setting a too high shore limit.)
The DMC is capable of dealing with a Quattro or an extended VE. bus system has more than 1 AC input. When the system switches over from one AC input to another, the DMC switches too, setting the current limit to the last used value for that AC input.
In the Multi/Quattro configuration, it is possible to indicate that a shore current limit is not to be overruled by the remote panel. In such a case the DMC will not display ashore current limit value but it will display the AC input identification as, or.
If in a system with more than 1 input, the corresponding input does allow changing by the remote the panel, the DMC will display the shore current value and the AC input identification alternating.
The exception to this is AC input 1. If AC input 1 is active only the shore current value will be displayed and not the AC input identification.
