Control Board (A1):
The Control Board is based on a micro-controller and a digital signal processor (DSP). Together they
regulate, supervise and diagnose possible external and internal faults. As soon as the ground power unit
is connected to the mains, and constantly during normal operation, the Control Board runs through a
self-check program which checks all internal
functions of the ground power unit. If an internal or
external error is detected, the display shows the nature
of the error. All immediate parameters related to a
shut-down are stored in the ground power unit’s
memory. The Control Board has an on-board Ethernet
RJ45 connector which can be used to communicate
with the BMS (Building Management System) and
USB host Type A connection to retrieve data from the
converter or to update the software.
Display Board & Keyboard (A3 / A4):
The display module serves as the interface for daily operation.
The display communicates with the Control Board via a CAN bus
(Controller Area Network) and can be placed up to 100 m away from the
unit when using the Remote Control Box.
Furthermore, the display module
includes a USB connection which can be used to download the Black Box
and the Power Log and for update of the display software.
