The Reset and an Engineer Mode buttons are located on the Control PCB inside the front lid. The Engineer Mode button
is used to allow configuration and testing of the system. The Reset button is normally only used to manually initiate a
clean restart to the system, or to reset test calls that have been made from unassigned Type B outstations.
15 Fault Messages
Faults on the EVCS are normally non-latching and will clear if the fault disappears.
The only exception being a watchdog fault which occurs at initial power-up, or after
a system reset and stays latched until manually cleared. Normally this fault clears
when accepted and the MCU/LCU reverts to normal operation.
If the EVCS has been configured previously and any extensions are now missing, or
are incorrectly connected the relevant faults are displayed.
The display (right) shows a typical display but may have a different number of faults.
Press CALL/ACCEPT button to view the fault(s).
