Preventative Maintenance
ETC Matrix II dimming systems are designed for long and reliable service, but will benefit from annual
checks of parts of the system. This section outlines the sort of checks which should be part of any
regular maintenance regime.
Fuses
o With power switched off, remove each fuse and inspect for corrosion or any signs
of arcing
o Replace any fuse carriers which appear cracked or damaged in any way
o Replace the fuses and check they are tight in the fuse carriers and are not
inserted at an angle to the bus bars
o Replace all fuses every 5 years to prevent nuisance failure through aging
Terminations
o With the main supply isolated from the rack, check the bus bar fixings are tight.
o Check the tightness of all load terminations.
o Check all data cables and make sure they are correctly located in their sockets.
Ventilation
o On each module, depress the test button (on the front panel) for 5 seconds to test
the operation of the fan.
o Replace the fan if it does not run, or if it is noisy
General
o Clean all modules, fans and the rack.
