All functions and system components that are important for the
SHEVS operation are constantly monitored for faults. A fault indication
signals the type of fault and, respectively, possible errors when connecting
system components (such as back-up batteries, detectors, drives) during
commissioning of the Control Unit.
The system software offers the possibility to check the
system behaviour in detail. Even when contacting our
support team on the phone it is helpful to have available
a computer with the system software installed.
The confi guration of the Control Unit using the software
has a signifi cant impact on the functionality of the indivi-
dual system components. Therefore, it might be necessary
to connect a computer provided with the system software
for precise testing.
The overview below details some of the possible faults and problem
cases and their causes. „Indicator
B
“ means the green operating indi-
cator which does not light up in case of a fault. The yellow “Indicator
S
” signals the type of fault. You fi nd a list of all indicators in chapter
„I
NDICATOR
AND
C
ONTROL
ELEMENTS
“.
