temperatures of adjacent devices. Also check the temperature for high ambient
temperature.
Over voltage alarm
The dimmers affected by either an over or under-voltage condition will report the
problem and will then shut down until the voltage returns to the specified range. This
is to protect the loads from high voltages which would affect the life of the lamps
connected. Check that the default voltage calibration settings are correct. If these are
too low, a small variation in nominal voltage may cause nuisance reports and dimmer
switch off.
DimStat data loss
If DimSTAT loses communication to the dimmers, the first step is to check the
mechanical connections to the network. If this is intact, reboot the PC and check
communications and the port settings, in case the settings have been corrupted by
additional software loaded on the hard disk .
DMX data loss
The Matrix dimmer has a backup scheme for DMX whereby the response to a failure
of DMX can be set to hold the last valid DMX state, fade to blackout, or go to a preset
state.
If there is a partial DMX loss, it may be caused by a dimmer rack being removed and
breaking the link from one rack to the next, or that the DMX cables have been
connected incorrectly when a dimmer rack is replaced.
