Table 2: The Fault LEDs
FAULT Group
DESCRIPTION COLOUR MEANING
FAULT Yellow If this LED is On (solid), at least one system fault has been detected.
The other LEDs in this group indicate specific faults. If this LED blinks,
one or more fault events have been cleared and saved to the memory.
You can access the events log to view the event/s concerned.
LOGIC UNIT Yellow If this LED is On (solid), the logic unit is not working properly
(motherboard microprocessor out-of-order). Under these
circumstances, immediate technical assistance is required as system
functionality is gravely at risk. The cause of this fault must be cleared
and the motherboard microprocessor must be restored to proper
working order. If this LED blinks, the motherboard microprocessor has
re-initialized (due to system shutdown or jamming).
Danger: If this LED blinks, the efficiency of entire system
must be checked. This LED stops signalling when
the panel resets.
BATTERY Yellow If this LED is On (solid), the battery is not working properly. This may
be due to either battery inefficiency, in which case the batteries must
be changed, or to a drop in power-supply voltage (voltage below
threshold), in which case the voltage must be restored in order to
charge the batteries. If this LED blinks, a battery fault event has been
cleared and saved to the memory.
EARTH Yellow If this LED is On (solid), voltage dispersion to earth has been detected.
Immediate maintenance is required to clear this fault. If this LED
blinks, voltage dispersion to earth has been cleared and saved to the
memory.
FUSE Yellow If this LED is On (solid), one of the resettable fuses has blown. This
fault may be due to a malfunction related to the AUX and AUX-R
terminal connections. If this LED blinks, a malfunction related to the
AUX and AUX-R terminal connections has been cleared and saved to
the memory.
MAINS Yellow If this LED is On (solid), the Mains power has been cut off (blackout),
therefore, the power supply cannot power the system or charge the
batteries. If this LED blinks, a Mains failure event has been cleared and
saved to the memory.
