2.2 Mounting the Hurricane Enclosure

The Hurricane enclosure may be mounted horizontally or vertically, on a solid structure, truss
or equivalent, rated for the weight of the enclosure and any equipment housed inside it.

Snow – if installed outside in cold regions, the lowest part of the Hurricane enclosure must be
at least 2’ (60cm) above maximum height of any snowfall or drifting snow, subject to local
conditions. If snow is not a consideration, then the enclosure must be installed at least
12”/30cm above ground level and maintained clear of drifting leaves and other potential
blockages to good drainage.

Enclosure will need to be powered at all times, although projector may not be.

LEAVE ADEQUATE CLEARANCE AROUND ENCLOSURE TO OPEN TOP COVER FOR SERVICE

Tempest Lighting recommends the use of stainless steel mounting hardware.
The Hurricane enclosure is provided with a pair of Unistrut channels under the enclosure base, for
mounting to your structure. You may use standard Unistrut accessories, or purchase either of the
mounting kits available from Tempest Lighting – four kits are required per enclosure.
4900.MB Stainless Steel Unistrut channel nut, bolt and
4900.MC Stainless Steel Unistrut channel nut, bolt and
washer. Four required per enclosure.
pipe clamp, for pipes 1.5” (38mm) to 2” (50mm) OD.
Four required per enclosure.
4925.MC Stainless Steel Unistrut channel
nut, bolt and pipe clamp, for pipes 2”
(50mm) to 2.5” (64mm) OD. Four required

2.3 IMPORTANT: Orientation
Hurricane Enclosures may be mounted in the any orientation, subject to any limitations
stipulated by the manufacturer of the projector housed inside it. You are advised to check
the projector manufacturer’s installation manually carefully before planning your
installation.
Hurricane Enclosure User Manual

2.4 IMPORTANT: Drainage Holes
When the enclosure is installed, drill two 1/4” (6mm) holes at the lowest point in the
enclosure, to allow any water inside the enclosure to drain away. If the enclosure is
mounted vertically, drill two holes in the bottom of the lower fiberglass cowl.
The NEMA 3R standard to which the enclosure is designed allows some water ingress,
provided there is a drainage path for the water to escape. Small amounts of water will not
cause any damage, provided they can drain away.

3.1 Electrical Preparation

All electrical work must be carried out by a properly licensed electrician. Failure to
observe this point will void the factory warranty for the Tempest Enclosure and possibly
the luminaire/projector.
1
Before starting work, switch off power to the branch circuit, carefully following lockout and
tag-out procedures. Failure to do so could cause serious injury or death.
2
Two electrical junction boxes will be required within a short distance of the Hurricane
enclosure for:
•
AC Supply wiring
•
DMX Control wiring
AC Power
DMX Control
Flexible weatherproof conduit
3
All junction boxes must be installed in accordance with local electrical codes and should be
located near the permanent installation of the enclosure. Each junction box requires a length
of 1/2" (20mm International) flexible weather-resistant conduit, long enough to reach from
junction box to the enclosure conduit entries.
4
The AC supply must be 200-240VAC, and must be protected by a fuse or circuit breaker of a
rating suitable for the projector, plus 650 watts max for the enclosure fans and heaters.
5
Connect the local junction box to the Hurricane enclosure using exterior grade flexible
conduit. Pull suitably rated wires through the conduit to supply the Hurricane enclosure and
connect as described below.
6
Alternatively, you may run separate AC feeds for the projector and the enclosure. Follow
either single or double-feed wiring instructions below, according to preference:

DEC 3.2 Control – Introduction
Tempest Lighting and Projector Enclosures have been in daily use around the world for almost a
decade. Tempest enclosures protect expensive and delicate equipment in all climates, maintaining
a comfortable operating temperature, and preventing condensation – the real outdoor enemy.
DEC3.2TM – that’s Digital Enclosure Control, third Generation, revision 2 – is the brain of your
Tempest enclosure. It will maintain the internal environment in a comfortable temperature and
humidity range, and prevent condensation – the real equipment killer. DEC3.2 monitors internal
temperature, humidity and lamp current at all times, and uses this information to control its lamp
relay, fan(s) and heater(s). It can report back over the DMX cable, using the RDM protocol (Remote
Device Management) if desired.
Unless otherwise specified, this version of the user guide refers to DEC3.2 units fitted with software version
0.1.xxx or later.
So, what does DEC3.2 actually DO?
The DEC3.2 Engine is the brains of the operation – here’s a layout:

DEC3.2’s mission is to maintain temperature and humidity inside the enclosure, within determined
bounds, and to prevent condensation – particularly overnight dew formation – inside the
equipment housed. Condensation is fatal to electronic equipment, particularly in polluted areas or
saline environments, where it brings not only rust and short-circuits, but also a steady buildup of
mineral and/or salt deposits. Incidentally, condensation is very hard to control with airconditioning type systems, which is why we don’t use them.
Broadly speaking, DEC3.2’s function depends on whether the fixture/projector lamp is on or off:
Lamp ON
When the projector/fixture is running, the heat from the lamp takes care of humidity, and
DEC3.2 runs the enclosure’s fan(s) to change its air every couple of seconds – ensuring
high-velocity forced-air cooling while the lamp is on.
Lamp OFF
When the lamp is off, DEC3.2 senses temperature and humidity and controls its fan(s) and
heater(s) accordingly. When conditions are within normal bounds (between top and
bottom temperature settings and below the humidity threshold (see below), DEC3.2
pulses the heater at a low level to dry the air and eliminate condensation, and runs the
fans to change the enclosure air every 30 seconds or so. We call this ‘pulse mode’, and it
is the key to preventing damaging condensation inside your equipment.
If the temperature rises above the top set limit (see below), DEC3.2 runs the fans to cool it
down. In cold conditions, DEC3.2 will run the heater as required to maintain the bottom
set temperature.
Thus, DEC3.2 maintains a comfortable operating temperature inside the enclosure, and
prevents damage from condensation. Users all over the world have found that Tempest
enclosures provide an optimal environment for expensive and delicate equipment, in
every climate type.
And while doing all of this, DEC3.2 can tell you what’s happening over your RDM network – a real
boon in larger installations. You may also use RDM to configure your Tempest installation
remotely, using an appropriate RDM front end.
Default Operation
In most lighting and in almost all projector enclosure applications, DEC3.2 will work just fine with
its factory default settings. You do not need to do anything other than connect power and switch
on. We call this Basic mode, and it will apply to most installations. If your needs are more
complex, read on.
If not, you can skip to the Power Connections section below.
Operating Modes
DEC3.2 may be run in one of three basic operating configurations with a fourth configuration for
test and service use by trained personnel only. In the RDM context, these configurations are the
device’s DMX PERSONALITY.
Hurricane Enclosure User Manual
page 13
The DEC3.2 mode or personality may be configured form the Front Panel or by using an RDM
control. In all configurations, the fixture inside the Tempest enclosure may also be an RDM
enabled device.
Basic Mode
This is the way your DEC3.2 controller will normally ship from the factory. It will
be set up for standalone operation, with settings that will be appropriate for most
installations.
In most cases, Basic Mode will work fine for you. You only need to change it if you
will be using DMX or RDM (and if these terms are not familiar to you, you
probably won’t) or if you have to deal with extreme climate conditions.
You may set temperature and other parameters while using Basic Mode.
Monitor Mode
The enclosure operates independently, and automatically, requiring no user
intervention. Users may set parameters such as temperature and humidity
thresholds, and monitor sensor information and DEC status at the DEC3.2 using
the display, or remotely, using RDM over a DMX512 network. In this mode, the
DEC3.2 does not need to “see” any DMX to operate.
Control Mode
This mode has all of the Monitor Mode features plus control of the Lamp Relay
using a single DMX slot at the address configured as the DEC3.2 DMX start
address.
A DMX slot value (level) > 75% will cause the fixture to be powered and less than
25% will disconnect the power form the fixture. On DMX fail, the Lamp Relay will
default to power the fixture, unless it detects a thermal condition that would
cause it to isolate power from the fixture/projector.
DMX control of the Lamp Relay has the useful attribute of enabling the user to
remotely force a hard reset of the fixture by controlling power to it. This mode is
recommended for show-control applications, where it is desirable to have power
control of the internal fixture and accidental loss of the DMX data is very unlikely
to occur.
To force a hard fixture reset, take the enclosure’s DMX channel to zero (or any
level below 25%), allow time for the fixture’s power supplies to fully discharge,
then restore the enclosure’s DMX channel to full (or a level above 75%).
Service Mode
This mode is intended for test and service use only, giving the user direct control
of the Lamp Relay, fan and heater controls over three DMX slots. Users may NOT
override any of the controls in an unsafe direction – for example, if the DEC3.2
has determined the enclosure is over-temperature and has switched off the power
to the fixture, the Lamp Relay may not be controlled by DMX. In this sense, DMX
Hurricane Enclosure User Manual
page 14
‘piles on’ to DEC3.2 operation, within defined safety limits. However, until such
time as the temperature reaches the TOP limit, the heater may be enabled and the
fan disabled, which is why the mode should only be used for Test and Service use
by a trained technician.
DEC3.2 Control Parameters
DEC3.2 will run out of the box with its default parameter settings, which equate to the (fixed)
settings of its predecessor DECs 1 and 2.
Temperature:
Top Set
Range 35-45°C, Default = 40°C
Most manufacturers recommend a max temperature for their
equipment of 40°C, though this does vary. When DEC3.2 senses a
temperature higher than Top Set, it indicates an overtemp
condition as a warning. NOTE: in moving light enclosures the
thermal sensor is necessarily placed in the exhaust air path,
which will be higher (sometimes a lot higher) than the actual
fixture ambient. This needs to be kept in mind when adjusting
temperature settings.
Cutoff Temp
Range 0-15°C, Default = 15°C
This is a setting above the Top Set temperature that determines
the temperature at which the lamp relay is opened cutting off
power from the fixture/projector. User may reduce it as desired,
but should establish before doing so the actual operating
temperatures experienced in hot weather before doing so, to
avoid nuisance tripping.
Bottom Set
Range 0-10°C, Default = 10°C
The temperature maintained by the heater in cold conditions.
Most equipment manufacturers recommend a minimum
operating temperature of 0°C, and users may set it lower than the
default if desired.
Humidity
Range 50-90%, Default 80%
The threshold at which incoming air is more aggressively heated to remove
moisture.
DMX Address
Range 001-510, Default 001
Sets the DMX address for the lamp relay control. In the DMX/RDM service mode,
the subsequent two DMX slots control fan and heater respectively.
Fan Overrun
Range 1-15 minutes, Default 5 minutes
This is the time that the enclosure fan(s) will run after the fixture/projector lamp
is turned off. As a general rule, the more powerful the lamp, the longer the
overrun should be, to prevent overheating while the lamp cools down.
Temp C/F
Default Celsius
Hurricane Enclosure User Manual
page 15
DEC3.2 displays temperatures in Celsius or Fahrenheit.
Lamp Hours
Default 0000
DEC3.2 counts the hours your projector/fixture lamp is on, and can report it both
on the user interface display and over RDM. Remember to reset to 0 when
changing lamps. This is provided to allow lamp hours monitoring on devices such
as Video Projectors that have no native RDM or DMX support.

4 Setup and Connections
DMX Connections
DMX refers to USITT DMX512, a commonly used control protocol in the entertainment industry,
running over RS485. Consult USITT DMX installation guidelines when laying out a system, or
employ a qualified DMX system integrator.
Note that DMX is optional – in many applications it is not required, and need not be connected. A
DMX network will be required if:
a)
The fixture inside the enclosure requires a DMX control signal
b)
You wish to monitor the enclosure using RDM
c)
You wish to control the fixture power over DMX
DMX Terminations

(4) will then be the DMX OUT for the
enclosure. If the enclosed fixture does not
use the DMX connection, then DMX
connection (2) on the controller becomes
the DMX OUT for the enclosure.
DMX Line Terminations
DMX cable runs must be terminated at
the far end of the cable run with a
termination resistor as detailed in the
DMX512 standard.
The individual fixtures installed inside the Tempest enclosures must NOT be terminated.
It is recommended that any line termination is done using the 3-pin terminal connector fitted to
the DEC3.2 control circuit board.
Hurricane Enclosure User Manual
page 17
RDM Connections
RDM refers to ANSI E1.20, a control protocol in the entertainment industry gaining popularity and
essentially an “extension” of DMX512. The use of RDM is optional, and uses the same RS485 cable
connection as DMX512, so no additional wiring is required.
It is the responsibility of the user to ensure that any DMX splitters or other routing devices used
are rated for RDM as well as DMX use.
Power Connections
IMPORTANT
Tempest enclosures are supplied for either 120VAC 50/60Hz, or 208-
240VAC, 50/60Hz operation. Tempest Lighting is not liable for damage or
failure to operate correctly due to connection to an inappropriate electrical
supply.
ALL ELECTRICAL CONNECTIONS MUST BE UNDERTAKEN BY A QUALIFIED
ELECTRICIAN, IN COMPLIANCE WITH LOCAL NORMS AND STANDARDS.

Split or Common Supply Wiring
IMPORTANT: Tempest enclosures with any generation of DEC control MUST be powered
24/7, in order to protect equipment from condensation and temperature extremes.
The AC power feed must be adequate and appropriately fused/protected for the greater of the
projector/light fixture load (see manufacturer’s instructions) and the Tempest enclosure (see
enclosure manual). Since the enclosure heater(s) never operate when the projector/fixture lamp is
on, it is NOT necessary to rate the power service for the SUM of the enclosure and the
projector/light fixture.
Common Feed operation (factory default)
Tempest Enclosures are normally supplied wired for common electrical supply for the enclosure
(DEC3.2) and the projector/light fixture to be enclosed.
Connect incoming power to the terminals labeled MAINS:
(E) Earth/Ground
(L) Live
(N) Neutral
Split Feed Operation
Split Feed allows you to run the projector/light fixture independently of the enclosure. The
enclosure must be powered 24/7.
DEC3.2 normally ships from the factory with circuit card power links in place for a common
electrical supply to feed the enclosure and the projector/fixture inside it.
To feed the enclosure and projector separately, you will
need to remove the bridging links on the controller
circuit board as shown in the illustration, before
connecting to mains power.
Use a pair of small side cutters to cut the bridging links
from the circuit board, taking care to not damage any
tracks on the card.
When splitting the feeders, we strongly recommend
feeding both supplies from the same phase and at the
same supply voltage.
Feeds must be adequately dimensioned and fused for the loads used.
Connect incoming enclosure power to the terminals labeled MAINS. This supply MUST be
maintained 24/7.

RDM is an effective and powerful tool for commissioning and monitoring an
installation, particularly in large systems. For further guidance, we
recommend you consult a qualified RDM system integrator. If you don’t
have one in your neighborhood, go to www.tempestlighting.com, and click on the RDM and RDM
Integration bug on the FAQ page for some useful contacts. Tempest Lighting warrants DEC3.2 to
be compliant with the RDM standard, but is not an RDM systems integrator, and can offer only
basic guidance on RDM utilization.

Control Interface
The control interface features a 2-line display, LED indicators, and 4 sealed control buttons.
LED Indicators
Heater
SHORT PULSES (Green) – Indicates lamp is off, and the heater is pulsing to prevent
condensation inside the enclosure and projector/light fixture. This is normal operation
when the lamp is off and the temperature range is above the bottom set limit. Timing
intervals may vary – this is normal.
ON (Green) – Indicates heater is on, due to temperature being below bottom temperature
setting when lamp is off.
OFF – indicates lamp is on and maintaining temperature above bottom limit.
Fan
SHORT PULSE (Green) – The fan is moving a little air through the enclosure, as part of the
condensation prevention strategy. The fan comes on for a few seconds approximately
every 30 seconds.
ON (Green) – Fan is running, due to lamp being on or internal temperature exceeding top
limit.
Lamp On
ON (Green) Indicates current sensed on the lamp circuit greater than 0.5 amp (this allows
some current to be drawn for such things as fans and control electronics without the
Lamp On indicator lighting. When the Lamp On indicator is on, the lamp counter is
counting lamp life.
Lamp Relay
ON (Green) – Indicates lamp relay closed and power is available to the internal fixture.
OFF Indicates lamp relay open and power is removed from the internal fixture.
Temp
ON (Green) – The temperature is between Bottom and Top temperature settings.
ON (Red) – The temperature is either:
a)
Below Bottom Setting
b)
Above Top setting but below the Cutoff level.
FLASHING (Red) – Temperature is above Cutoff level or below Bottom level.
DMX (Not used in BASIC Mode)
Hurricane Enclosure User Manual
page 21
OFF – No DMX received (Basic Mode)
ON (RED) – DMX Fail
ON (GREEN) – Good DMX or RDM data packet received. Note that in Monitor Mode the DMX
indicator will only be green when RDM packets are being received. In this case a RED LED
is not indicating DMX failure, just that no data is being received from the RDM monitor.

RESET LAMP HOURS
The lamp hour counter needs to be reset each time you change the lamp in the
fixture/projector. Make this a part of your maintenance instructions.
HUMIDITY SET
The humidity level above which the heater kicks in to remove humidity from
incoming air (default 80%, permissible range 50-90%).
SET FAN OVERRUN
The fan will continue to run for a time after the internal fixture has gone to standby. This
facility allows the heat built up in the fixture to dissipate before the DEC3.2 resumes
normal maintenance of the enclosure.
(default 5 minutes, permissible range 0-15 minutes)
SET TEMP RANGES
Set three temperature trigger points for Bottom, Top and Cutoff temperatures.
TEMP BOTTOM
The desired lower temperature limit for normal operation
(default 10°C, permissible range 0-10°C).
TEMP TOP
The desired upper temperature limit for normal operation
(default 40°C, permissible range 35-45°C).
When the DEC3.2 sees air above this temperature, but below the additional Cutoff
temperature (see below), it indicates a temperature error. This is not dangerous.
TEMP CUTOFF
The desired upper temperature ABOVE the TOP TEMP setting, at which the lamp relay is
forced to open, isolating the fixture/projector power.
(default 15°C, permissible range 0-15°C).
To avoid nuisance tripping, set this variable to the maximum, and monitor actual
temperatures in your normal operating conditions. If your actual temperatures are
running lower, then you may reduce the cutoff temperature margin. In hot climates, it
may be advisable to set both TOP TEMP and CUTOFF TEMP as high as possible.
SET TEMP C OR F
Choose to display temperature values in Celsius or Fahrenheit (default Celsius)

Mounting the Projector in the Hurricane Enclosure

For safety, this must be done by two or more people.
IMPORTANT: The Hurricane enclosure MUST be securely mounted BEFORE you
attempt to install the projector.
1.
Your Hurricane enclosure is normally supplied with a low-profile yoke already installed, for use
with the scanner type specified on your order. These will vary slightly, depending on fixture type.
2.
Note carefully how the yoke supplied with your scanner fixture is attached to the fixture.
3.
Remove the original yoke supplied with your projector and keep the securing hardware.
4.
Carefully place the projector in the yoke mounted in the Hurricane enclosure, and attach it using
the hardware removed from the original yoke.
5.
MAKE SURE THAT THE MIRROR IS FACING UP (away from the enclosure base), and is positioned
approximately center to the projection window. You can move the yoke along its mounting strut
to adjust this if you need to.
6.
Check that all mounting bolts are tight and secure.
7.
Plug the fixture into the receptacle in the DEC cover, and connect the DMX control in compliance
with the fixture manufacturer’s installation manual.
Hurricane Enclosure User Manual
page 25

Activation and Checkout
Now the installation is complete, the time has come to activate the enclosure and make sure it is
working properly.

Be aware that once the enclosure has had power applied to it, the heaters will get hot and the
fans will start to turn. Make sure that your hands and any cables or other objects are clear of
both of these areas before applying power to the enclosure.
1.
Clear enclosure and projectors of all debris.
2.
Set up the projector in accordance with the manufacturer’s instructions.
3.
Focus the projector, then close the enclosure cover.
4.
The system is now ready for use.
Note
The enclosure can be secured with padlock at this point. Only qualified personnel should be accessing
the enclosure.
7
Operation
See section 4 for detailed operating instructions.

Regardless of whether the projector is in use, power must be maintained to the enclosure
at ALL TIMES. The Digital Enclosure Control system will work 24/7 to ensure that optimum
temperature and humidity are maintained, preventing condensation, overheating and
freezing. This is critical to attaining optimum projector lifetime.

The cooling fans will only turn when power is applied to the enclosure. Fans will stop turning
when power is cut to the enclosure, but the heater may remain hot to the touch for up to one
hour – be careful when opening the enclosure immediately following a power down.

Unless the enclosure or projector is undergoing routine maintenance, the enclosure should be
closed and securely latched at all times.

Only authorized personnel should open the enclosure (see maintenance warnings in the next
chapter).

If the safe operating temperature is exceeded, the over-temperature shutdown feature may
engage and temporarily cut off power to the projector. Once the temperature reaches acceptable
levels, power will be automatically restored. This is extremely unlikely to occur during hours of
darkness when the projector is in use. To avoid nuisance cutoffs, set the Top Temp and Cutoff
Temp settings to their maximum (see chapter 4)

Do not routinely operate projector in full sun in hot weather. The enclosure has not been
designed to protect the projector in this extreme condition.
Hurricane Enclosure User Manual
page 26
8
Routine Maintenance
It is very important to perform routine maintenance on both the enclosure and the projector
inside it. Failure to do so may reduce lifetime for both the enclosure and the projector.
Note
Maintenance schedules depend on location and environment. The intervals given here are
general minimum guidelines. It is up to the user to judge whether maintenance should be carried
out more frequently. We recommend doing these tasks no less often than mentioned here.
Safety

As the enclosure is a powered unit with moving parts, it is necessary to keep safety in mind while
performing routine maintenance. Although maintenance can be performed while the enclosure is
powered, it is safer to carry it out with the power disconnected with proper lockout and tag out
procedures followed.

Be aware that once the enclosure has had power applied to it, the fans will start to turn. Make
sure that your hands are clear of the fans before applying power to the enclosure.

Only authorized personnel should perform maintenance on the enclosure or luminaire

Do not service the unit in the rain or other adverse weather conditions (snow, sleet, high winds,
etc.).
Inspection Checklist: - Every Three (3) Months


Hurricane Enclosure User Manual
page 27
Air Filters - Every Three (3) Months
The air filter from the intake vent on rear of enclosure (left side) should be removed and cleaned
on a regular basis. To remove filters, open the enclosure, reach into the inlet duct, and pull out
the filter. The filters can be cleaned by running water from a hose and do not require any special
cleaning solution.
To reinstall, push filter fully back into the inlet duct until it presses on the inside of the inlet
cowl. The filter will be held in place by velcro tabs.
Warning: Make sure that the filter is never left in contact with the heater, when the
enclosure is in use.
Replacement filters may be obtained from your Tempest Lighting Dealer.
Case - As Needed
The outside of the case should be cleaned as needed. The case should be cleaned with a wet
cloth and mild detergent (if necessary). Do not use a direct spray from a hose to clean the case.
Do not use hydrocarbon-based cleaners.
Window – As Needed
Clean using a proprietary glass cleaning solution or a mild detergent, and wipe dry. Use only
soft, lint-free cloths for glass cleaning. Never use an abrasive cleaner.
Projector
Review the manufacturer's instructions for proper maintenance of your luminaire/projector.
Remember, the enclosure simply protects the equipment inside it and is not a substitute for
regular maintenance.
Hurricane Enclosure User Manual

Troubleshooting
This is a guide to the general symptoms, problems, and solutions that may occur during the
usage of your enclosure. However, it is important to remember that problems may occur within
the luminaire itself and these must also be considered.
Projector does not have power.
Check power supply wiring and voltage.
One or more fans are not spinning
Fans may be obstructed. Shut off power to enclosure and check for obstructions. Turn power
back on to see if fans will start spinning. If fans do not turn and display on temperature
controller is lit, contact technical support. If fans do not turn display is not lit, then enclosure is
not receiving power. Turn off all power and check wiring. If the wiring is correct, contact
technical support.
Fan cords may have become disconnected. Check connections between fan and cord. Make sure
that the ribbed side of the cable is on the positive side of the connection (the fans are DC
powered).
Projector does not have power.
Check projector power switch. (Note: the following actions should be performed by a licensed
electrician) If switch is on, check wiring (including metering supply voltages, enclosure must
receive 200-240VAC to operate properly).
In case of over-temperature, the enclosure shuts down power to the projector, for its protection.
Projector power will be restored when temperature drops to an acceptable level. It is possible
that the air intake or exhaust has become clogged, leading to higher temperatures inside the
enclosure. Make sure that these areas are clear, the filters are clean, and the fans are working
properly.
Projector turns on and off repeatedly over short span of time.
Check that vent areas and airways are clear. If so, ambient temperature may be too high (see
over-temperature note above) or projector may have internal problem.
Excessive water in enclosure.
Glass seal leak. Repair with silicone sealant.
Door gaskets leak caused by separation. Silicon piece back into place or replace section.

Note: terminals shown with gray text descriptors are factory wired and should not be changed. Only terminals
shown with descriptors in black/bold font are for installer use.
DEC3 normally ships from the factory with power terminal links inserted for a common electrical
supply to feed the enclosure and the projector/fixture inside it.
If you prefer to feed the enclosure and projector separately, remove the terminal links as indicated
before connecting to mains power. Use a small flat-bladed screwdriver to remove the link, snap off the
unneeded section and replace carefully. When splitting the feeders, we strongly recommend feeding
both supplies from the same phase and at the same supply voltage.

DEC3 Control – Introduction
Tempest Lighting and Projector Enclosures have been in daily use around the world for almost a
decade. Tempest enclosures protect expensive and delicate equipment in all climates, maintaining
a comfortable operating temperature, and preventing condensation – the real outdoor enemy.
DEC3TM – that’s Digital Enclosure Control, third Generation – is the brain of your Tempest
enclosure. It will maintain the internal environment in a comfortable temperature and humidity
range, and prevent condensation – the real equipment killer. DEC3 monitors internal temperature,
humidity and lamp current at all times, and uses this information to control its lamp relay, fan(s)
and heater(s). It can report back over the DMX cable, using the RDM protocol (Remote Device
Management) if desired.
Unless otherwise specified, this version of the user guide refers to DEC3 units fitted with software version 2.1
or later.
So, what does DEC3 actually DO?
DEC3 is the brains of the operation – here’s a layout:

This schematic
shows the
relationship between
DEC3’s functional
elements.
The power supply is
universal 90-260V,
but fans and heaters
are either 120V or
230VAC, and must
be so specified.
A high-quality
25amp 2-pole
electro-mechanical
relay isolates
fixture/projector
power in the event of
an over-temperature
condition.
Fans and heaters are
switched using
generously overrated
40amp Triac devices
for maximum
reliability.
Two DMX outputs
connect to the
internal fixture (if
desired) and on to
other enclosures or
DMX devices.
DEC3’s mission is to maintain temperature and humidity inside the enclosure, within determined
bounds, and to prevent condensation – particularly overnight dew formation – inside the
equipment housed. Condensation is fatal to electronic equipment, particularly in polluted areas or
saline environments, where it brings not only rust and short-circuits, but also a steady buildup of
mineral and/or salt deposits. Incidentally, condensation is very hard to control with airconditioning type systems, which is why we don’t use them.
Broadly speaking, DEC3’s function depends on whether the fixture/projector lamp is on or off:
Hurricane Enclosure User Manual
page 37
Lamp ON
When the projector/fixture is running, the heat from the lamp takes care of humidity, and
DEC3 runs the enclosure’s fan(s) to change its air every few seconds – ensuring minimal
temperature rise above outside ambient.
Lamp OFF
When the lamp is off, DEC3 senses temperature and humidity and controls its fan(s) and
heater(s) accordingly. When conditions are within normal bounds (between top and
bottom temperature settings and below the humidity threshold (see below), DEC3 pulses
the heater at a low level to dry the air and eliminate condensation, and runs the fans to
change the enclosure air every 30 seconds or so. We call this ‘pulse mode’, and it is the
key to preventing damaging condensation inside your equipment.
If the temperature rises above the top set limit (see below), DEC3 runs the fans to cool it
down. In cold conditions, DEC3 will run the heater as required to maintain the bottom set
temperature.
Thus, DEC3 maintains a comfortable operating temperature inside the enclosure, and
prevents damage from condensation. Users all over the world have found that Tempest
enclosures provide an optimal environment for expensive and delicate equipment, in
every climate type.
And while doing all of this, DEC3 can tell you what’s happening over your RDM network – a real
boon in larger installations.
Hurricane Enclosure User Manual
page 38
Operating Modes
DEC3 may be run in one of three basic operating configurations. A fourth configuration is
provided for test and service use.
Standalone:
The enclosure operates independently, and automatically, requiring no user
intervention. User may set parameters such as temperature and humidity
thresholds, and monitor sensor information and DEC status at the DEC3 user
interface. Standalone is the default DEC3 shipping mode unless specified
otherwise at time of order. DMX is not required or utilized.
DMX/RDM Mode 1 (RDM Monitor)
All of the Standalone features plus the ability to discover and monitor the DEC3
over a DMX512 connection, using RDM.
In this mode, the DEC3 does not need to “see” any DMX to operate. The mode
allows the use of RDM to set the various temperature thresholds, and monitor the
conditions inside the enclosure remotely. The fixture inside the Tempest
enclosure may also be an RDM enabled device.
DMX/RDM Mode 2 (DMX Enable)
All of the Standalone and RDM Monitor features plus the use of a single DMX
address (slot) to control the Lamp Relay.
This means that the user is responsible for maintaining a DMX input with the slot
(as selected as the DMX START ADDRESS on the DEC3) high. This slot level must
be set greater than 50% at all times when the internal fixture is to be powered.
This has the useful attribute of enabling the user to remotely force a hard reset of
the fixture by opening and then closing the Lamp Relay. It also means that it is
unnecessary to feed the enclosure with two power sources (for the enclosure and
the luminaire/projector), since the DMX slot may be used to isolate the projector
when not in use, without removing power from the enclosure. This mode is
recommended for show-control applications, where it is desirable to have power
control of the internal fixture, and accidental loss of the DMX data is very unlikely
to occur.
In the absence of DMX, the Lamp Relay defaults to “ON”.
All RDM functions are available for configuration and monitoring of the DEC3.
DMX/RDM Mode 3 (Service/Test)
This mode is intended for test and service use.
It gives the user direct control of the lamp, fan and heater relays over DMX. User
may NOT override any of the relays in an unsafe direction – for example, if the
DEC3 has determined the enclosure is over-temperature and has switched off the
lamp relay, the relay may not be overridden ON by DMX. In this sense, DMX ‘piles
on’ to DEC3 operation, within defined safety limits. However, until such time as
Hurricane Enclosure User Manual
page 39
the temperature reaches the TOP limit, the heater may be enabled and the fan
disabled, which is why the mode should only be used for Test and Service use.
If the DEC3 has been purchased with DMX/RDM enabled, it is possible to select the required mode
1-3 using RDM. In the RDM context, this is known as selecting the device’s DMX PERSONALITY.
Setup of the DEC3 from the Front Panel is available in all configurations.
RDM is an effective and powerful tool for commissioning and monitoring an installation,
particularly in large systems. For further guidance, we recommend you consult a
qualified RDM system integrator. If you don’t have one in your neighborhood, go to
www.tempestlighting.com, and click on the RDM and RDM Integration bug on the home
page for some useful contacts. Tempest Lighting warrants DEC3 to be compliant with
the RDM standard, but is not an RDM systems integrator, and can offer only basic guidance on
RDM utilization.
DEC3 Control Parameters
DEC3 will run out of the box with its default parameter settings, which equate to the (fixed)
settings of its predecessor DECs 1 and 2.
Temperature:
Top Set
Range 35-45°C, Default = 40°C
Most manufacturers recommend a max temperature for their
equipment of 40°C, though this does vary. When DEC3 senses a
temperature higher than Top Set, it indicates an overtemp
condition as a warning. NOTE: in moving light enclosures the
thermal sensor is necessarily placed in the exhaust air path,
which will be higher (sometimes a lot higher) than the actual
fixture ambient. This needs to be kept in mind when adjusting
temperature settings.
Cutoff Temp
Range 0-15°C, Default = 15°C
This is a setting above the Top Set temperature that determines
the temperature at which the lamp relay is opened, cutting off
power from the fixture/projector. The user may reduce it as
desired, but should establish before doing so the actual
operating temperatures experienced in hot weather before doing
so, to avoid nuisance tripping.
Bottom Set
Range 0-10°C, Default = 10°C
The temperature maintained by the heater in cold conditions.
Most equipment manufacturers recommend a minimum
operating temperature of 0°C, and users may set it lower than the
default if desired.
Humidity
Range 50-90%, Default 80%
Hurricane Enclosure User Manual
page 40
The threshold at which incoming air is more aggressively heated to remove
moisture. This parameter will not normally require adjustment.
DMX Set
Range 001-510, Default 001
Sets the DMX address for the lamp relay control. In the DMX/RDM service mode,
the subsequent two DMX slots control fan and heater respectively.
Lamp Hours
Default 0000
DEC3 counts the hours your projector/fixture lamp is on, and can report it both
on the user interface display and over RDM. Remember to reset to 0 when
changing lamps. This is provided to allow lamp hours monitoring on devices
such as Video Projectors and certain moving lights that have no native RDM or
DMX support.

DMX Line Termination
DMX cable runs must be terminated at the far end of the cable run with a termination resistor as
detailed in the DMX standard. This is particularly important for satisfactory operation of DMX/RDM

installations. The individual fixtures installed inside the Tempest enclosures must NOT be
terminated. It is recommended that any line termination is done using the 3-pin terminal
connector fitted to the DEC3 control circuit board.
1. Make sure that any DMX termination provided by the fixture inside your enclosure(s) is
disabled.
2. The LAST enclosure in the installed DMX daisy chain should have a DMX Termination
fitted to one of the pass through DMX connectors. Per the ANSI E1.11 standard, the
Terminator shall be 120 ohm +5%/-10% impedance placed between Data+ and Data-. We
recommend minimum power rating of 0.6W for the resistor.
We recommend that the installer fit a label externally to say “DMX Termination fitted
internally”.
Test:
3. Switch mains power OFF to all enclosures.
4. Before connecting the DMX line to your controller, measure the impedance between Pin 2
(Data-) and Pin 3(Data+) at the controller end. Reading should be around 100-130 ohms.
This test shows that you have a terminator in place, and also that you have continuity of Data- and
Data+ between installed devices. If the measured resistance is significantly less than 100 ohms,
(say 40-80 ohms) it suggests you may have multiple terminations in place. Check that any
terminator switches on light fixtures are OFF. If impedance is very low, check for wiring shorts.
RDM Connections
RDM refers to ANSI E1.20, a control protocol in the entertainment industry gaining popularity and
essentially an “extension” of DMX512. The use of RDM is optional – but it does require a DMX512
cable connection.

Important – RDM and RDM Integration
RDM (Remote Device Management) is an ANSI standard that adds bidirectional discovery and
status monitoring to a standard DMX network connection. No additional wiring is required for
RDM operation.
DEC3’s RDM implementation allows system integrators to set up remote control and status
monitoring of all attributes and sensors, including:
•
Temperature
•
Humidity
•
Lamp Current
•
Elapsed Lamp Hours
•
Lamp Relay Status
•
Fan Relay Status
•
Heater Relay Status
•
DMX Status
•
DMX Start Address
•
DMX Personality (RDM Mode)
•
Device Type
•
Device Label
•
Software Version
Tempest Lighting warrants that its RDM products are compliant to the RDM standard, but does not
directly support RDM system integration. Tempest Lighting will however provide introductions to
qualified RDM system integrators for customers requiring assistance in this area. Links are
provided on the Tempest Lighting web site (www.tempestlighting.com).

The control interface features a 2-line display, LED indicators, and 4 cap-sense control buttons.
LED Indicators
Heater
SHORT PULSE (RED) – Indicates lamp is off, and the heater is pulsing to prevent
condensation inside the enclosure and projector/light fixture. This is normal operation
when the lamp is off and the temperature range is above the bottom set limit.
ON (RED) – Indicates heater is on, due to temperature being below bottom temperature
setting when lamp is off.
OFF – indicates lamp is on and maintaining temperature above bottom limit.
Fan
SHORT PULSE (RED) – The fan is moving a little air through the enclosure, as part of the
condensation prevention strategy. The fan comes on for a few seconds approximately
every 30 seconds.
ON (RED) – Indicates fan is running, due to lamp being on or internal temperature
exceeding top limit.
Lamp Relay
ON (RED) Indicates lamp relay closed and power is available to the internal
fixture/projector.
OFF Indicates lamp relay open and power is removed from the internal fixture.
Lamp On
ON (RED) Indicates current sensed on the lamp circuit greater than 1 amp (this allows
some current to be drawn for such things as fans and control electronics without the
Lamp On indicator lighting. When the Lamp On indicator is on, the lamp counter is
counting lamp life.
Temp
ON (GREEN) – The temperature is between Bottom and Top temperature settings.
FLASHING (RED) – The temperature is above Top setting but has not yet reached the
Cutoff level.
ON (RED) – Temperature is above Cutoff level or below Bottom level.
DMX (only used when DMX/RDM setting is in effect)
ON (RED) – DMX error.
ON (GREEN) – Good DMX or RDM data packet received.

Note that the DMX control is designed using a SAFETY pile-on Logic. In other words, the
DMX input can only override automatic settings in a safe manner. For example, if the
enclosure has switched off the lamp relay due to an over-temperature condition, the DMX
input cannot switch it on, if the fans are running because of Overtemp, the DMX input
cannot turn them off, and so on.
The DMX SET menu can be ignored if the DEC3 is in Standalone or DMX/RDM Mode 1 (RDM
Monitor) mode.
SET LAMP HOURS TO 0
The lamp hour counter needs to be reset each time you change the lamp in the
fixture/projector. Make this a part of your maintenance instructions.
STATUS DISPLAY
View Temperature (in Celsius) and Relative Humidity (in %) inside the enclosure. Note that
in Tornado moving light enclosures the temp/humidity sensor is located in the exhaust
airflow, which may be significantly warmer than ambient.
HUMIDITY SET
The humidity level above which the heater kicks in to remove humidity from incoming air
(default 80%, permissible range 50-90%). This setting should not normally be changed.
TEMP SET
Set three temperature trigger points for Top, Cutoff and Bottom temperatures.
TOP TEMP
The desired upper temperature limit for normal operation
(default 40°C, permissible range 35-45°C).
When the DEC3 sees air above this temperature, but below the additional Cutoff
temperature (see below), it indicates a temperature error. This is not dangerous, but may
reduce lamp life.
CUTOFF TEMP
Hurricane Enclosure User Manual
page 46
The desired upper temperature ABOVE the TOP TEMP setting, at which the lamp relay is
forced to open, isolating the fixture/projector power.
(default 15°C, permissible range 0-15°C).
To avoid nuisance tripping, set this variable to the maximum, and monitor actual
temperatures in your normal operating conditions. If your actual temperatures are
running lower, then you may reduce the cutoff temperature margin. In hot climates, it
may be advisable to set both TOP TEMP and CUTOFF TEMP as high as possible.
BOTTOM TEMP
The desired lower temperature limit for normal operation
(default 10°C, permissible range 0-10°C).
Note that a higher BOTTOM TEMP may provide additional protection against condensation
in some conditions, but will consume more energy. Therefore a lower setting is desirable,
provided the user is certain that no condensation is occurring.
RDM MODE SET
The RDM Mode is normally set using RDM commands from a remote RDM control device
to set the DMX PERSONALITY of the DEC3.
From the DEC3 user interface, this menu item allows the user to check (and if necessary
alter) the RDM mode. Please ensure that the DEC3 is NOT unintentionally left in Mode3
(Service/Test).
