Normal operation
In normal rehearsal and performance situations, the home screen is displayed with
the list of all dimmers in the system. This display normally shows green indications if
the dimmers are operating correctly, grey if communication is lost, and red if a
reportable fault has been received.
If a dimmer reports a fault, click on the dimmer reference or icon, and DimSTAT will
switch to the main screen. The fault reported will be a red warning related to a
dimmer channel number in the list of faults.
DimSTAT offers interrogation facilities for each dimmer in the system at any time. To
check the mains supply voltage, load current, temperatures etc, simply select a
dimmer and view the data in the main screen.
Saving and recalling dimmer system configuration settings
DimSTAT is able to save the settings for all dimmers in the installation as a file. It
follows that many settings can be saved for different shows or variable conditions or
a change of hook-up. Before saving a configuration, remember to send all changed
data to the dimmers and check that the settings are correct. The data in DimSTAT
should be considered as a copy of the dimmer settings, and therefore the data
should be compared before and after disk transfers.
For details, refer to the DimSTAT operator's handbook.
Matrix Dimming System Features
Modularity
Matrix Mk.II offers a wide range of plug-in power control devices including SCR and
Sine wave dimming, relay switch circuits and continuous power modules. Modules
can be exchanged safely with power applied, and modules with similar capacity can
be exchanged with each other (e.g. sine wave for SCR).
SCR dimmers
A wide choice of SCR dimmer modules are available with 400µS filters; 3kW, 5kW or
10kW capacity per channel; fluorescent versions with associated heater supply; a
choice of protection devices including MCB, RCD and RCBO.
Sine wave dimmers
Silent, low harmonic sine wave dimmer modules are available with options for 1.5kW,
3kW, 5kW and 10kW capacity per channel; fluorescent versions with associated
heater supply; a choice of protection devices including MCB, RCD and RCBO. Key
features of Matrix Mk.II sine wave technology are:
Silence: Silent lamp filaments. Sine wave does not eliminate natural filament
resonance from a 50Hz mains supply, but it is no more noisy than if the lamp head is
connected to a maintained mains supply. Buzzing cables, trunking, transformers and
switchgear are no longer a problem with sine wave dimming.
No reactive power: Creating less that 1% additional harmonic distortion and no 3rd
or 5th order harmonics, sine wave dimmers can actually be cheaper to run as the
reactive power demand is eliminated from supply bills. Costs are significantly less for
rewired venues, or new builds, because the usual requirement to overrate cables,
and switchgear by 40% is no longer an issue. That means a lot less copper and
