5.2 Fault Finding Guide
1.
Firstly, ascertain what is or is not happening with the system. There are commonly two scenarios.
i.
ALIS Lamp(s) are completely extinguished.
ii.
ALIS Lamp(s) are flashing or flickering.
2.
Once i or ii has been ascertained the next step is to find the reason.
3.
ALIS Lamp(s) are completely extinguished. If there is just one or more, but not all, ALIS Barn Lamps
extinguished open and remove it from the ALIS Bus at the same time inspecting the cable for damage. Check
the ALIS Barn Lamp is free of contaminates and if required clean with a soft cloth. If the ALIS Bus is OK, refit
the lamp. If the problem has not been resolved, replace the lamp.
4.
If all ALIS Lamps are extinguished continue as follows.
i.
Check the ALIS Power Hub status LED as described in section 5 (previous page) and attempt to resolve
the problem by carrying out the listed actions.
ii.
If the ALIS Power Hub status LED is showing a steady green light, and a technically competent person is
present, bypass the ALIS Dimmer by first disconnecting the 230VAC / 120VAC supply to the ALIS Power
Hub. Then disconnect the ALIS Dimmer from the ALIS Power Hub and ALIS Bus and reconnect the ALIS
Power Hub directly to the ALIS Bus. Reconnect the 230VAC /120VAC supply to the ALIS Power Hub will
confirm whether the ALIS Dimmer has a problem.
iii.
If the status LED is completely extinguished, check there is an adequate mains supply present. Once the
correct supply voltage level is ascertained attempt a power up reset. If this does not resolve the fault
carrying out the check list on page 15 before proceeding to replace the ALIS Power Hub.
5.
ALIS Lamp(s) flashing or flickering. If this is the observed fault, then it is most likely that the ALIS Power Hub
is not the problem. Ascertain whether it is a few lamps or all the lamps on the ALIS Bus. Is it continuous or only
occurs at certain times of day? Has it only just started to happen?
i.
If there are only a few of the ALIS Lamps showing fault systems, then it is likely a local problem to
those lamps. Open the ALIS Barn Lamp and remove it from the cable, at the same time inspecting
for cable damage. Check the lamps for contaminates and if required clean with a soft cloth. If the
cable is OK, refit the lamp. If the problem has not been resolved, replace the lamp.
ii.
If it is all the lamps on the ALIS Bus and the ALIS Power Hub shows no signs of fault, then it is most
probably an external issue such as electrical noise which can be very difficult to pin point. Firstly, try
to ascertain if there have been any changes in the immediate area such as new equipment installed
or any cable rerouting. As a process of elimination try to locate the problem item by switching off
other equipment. As this is a process of elimination a considerably amount of time may be required,
but in the end, the fault should be easily remedied.
6.
If any problems or faults occur that are outside any of the above, or you are having difficulties, please do not
hesitate to contact [email protected] for further guidance.
