System Interface Card ~ Terminals & Pin-out
Minipack systems are shipped from factory with the CON5 signals already connected.
Some of the Smartpack controller’s internal system signals are accessible on D-Sub connector
CON5, on the controller’s rear panel.
Using a standard 15 pins D-Sub cable, the signals on CON5 are routed to the Minipack system’s
main circuit board. See the figure in this section for an overview of the signals on CON5,
LVD Latching Contactors
Connections
Minipack systems’ LVBD and LVLD functionality (Low Voltage Battery Disconnect; LV Load
Disconnect) is implemented by the Smartpack controlling magnetically latching contactors.
The coil of latching contactors is not energized in any state. They change state from open to close,
or vice versa, when a reversed pulse is applied to the coil.
