Dec4 Main Functions; Factory Settings - Basic Mode - Tempest Tornado Marine G4 User Manual

DEC4 Main Functions

1. Sense current to luminaire (lamp on/off)
2. Record lamp hours
3. Monitor temperature and 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 luminaire 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
10. Circulates air internally to prevent hot and cold
spots when luminaire is idle
DEC3.3 constantly monitors the following parameters:

Luminaire/Luminaire current

Line Voltage

Temperature

Humidity
Factory Settings – Basic Mode

factory default settings, in Basic operating mode.
You do not need to do anything. Please skip to the Power
Connections section below.

Standard default temperature and humidity settings

DMX, RDM and Remote Monitoring disabled

Best for standalone operation

Supports TEMP remote monitoring – see appendix

Tornado G4 User Manual
DEC 3.3's patented Goldilocks
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.
