7 Fault Messages
Faults on the EVCS are normally non-latching and will clear if the fault disappears. The
only exception being a watchdog fault that occurs at initial power-up, or after a system
reset and stays latched until manually cleared. Normally this fault clears when accepted.
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).
When a fault occurs, the relevant fault indicator is lit and a buzzer sounds intermittently at the wall units. Some faults
may require investigation or assistance from the service company responsible for the EVCS.
8 Check the Wall Control Units are Working
If a wall control unit is healthy, the green Power indicator is lit, no fault or disablement
indicators are lit and the display shows the current system status, see typical displays
below.
Note
: The wall control unit displays are different for a networked system and a non-
networked system.
9 Handling Calls at the Wall Control Unit
Section 9.1 to 9.4 applies to both a non-networked wall control unit and the current master wall control unit on a networked
system. It is assumed that auto-answer mode is enabled; this is the mode most likely to be setup for the system.
Additional call handling facilities are available for a networked system, see section 16.
9.1
To answer a call
When an extension calls in, the ringer sounds and the
display’s red backlight flashes.
The display shows the name of the calling extension (or networked unit), see examples below.
Note
:
denotes a wall control unit and is only seen on a networked system.
To answer the call simply pick up the handset. The call is automatically connected and you may speak. The
display’s
red backlight returns to normal.
