DEC4 Main Functions
1.
Sense current to projector (lamp on/off)
2.
Record lamp hours
3.
Monitor temperature and relative humidity
inside Enclosure
4.
Monitor temperature outside enclosure
5.
Maintain internal temperature at safe operating
level
6.
Maintain relative humidity within safe limits to
prevent condensation
7.
Isolate projector in case of unsafe temperature
8.
Report status over RS485, RDM, TCP/IP
9.
Maintain positive pressure (optional) 24/7 to
prevent ingress of salt air and other
contaminants through the exhaust path
10.
Circulates air internally to prevent hot and cold
spots when projector is idle
DEC4 constantly monitors the following parameters:
Projector/Luminaire current
Line Voltage
External Temperature
Internal Temperature
Internal Relative Humidity
DEC 3.3’s patented Goldilocks
TM
algorithm uses a combination
of sensors, heaters and fans to maintain a safe operating
temperature and a safe relative humidity level that will not
allow condensation to take place.
As air is heated it is able to support more moisture without
condensing, so Goldilocks uses heat to raise the air temperature
inside the enclosure in the event that relative humidity
approaches dewpoint.
Factory Settings – Data Modes
In most applications, DEC4 will operate correctly with its
factory default settings, in Basic operating mode.
You do not need to do anything. Please skip to the next
section.
Standard default temperature and humidity settings
DMX, RDM and Remote Monitoring disabled
Best for standalone operation
