4.4 - Diagnostic LEDs
The X series is fitted with an advanced diagnostic indicator system. There are two small indicator LEDs
(one red, one orange) within the unit, visible through the front lens.
When the unit is first turned on, both LED’s will flash briefly. This is normal operation and is part of the
start-up procedure, to show that the LEDs are functioning. During normal operation the indicator LEDs
should not be illuminated.
The table below summarizes the detected fault modes:
X Series
Red LED Orange LED Description
Flashing O The unit has been shutdown if the temperature is too high.
O On Input voltage is too low – less than ~9V. Check voltage of power source and
cabling for bad connections and rectify.
O Flashing Input voltage is too high – above ~32V. Check voltage of the power source
and rectify.
Flashing Flashing Unit has detected a fault with the wiring or the power source is not capable
of supplying the required current. The input voltage is dropping below
the minimum allowed during start-up. After five start-up attempts the unit
will shut down and both indicator LEDs will flash continuously. This could
be due to a poor power source (e.g. discharged battery) or voltage drops
caused by poor connections or incorrect wire gauge.
Flashing On Internal fault detected with temperature sensor – if this issue persists
contact your dealer.
