1 Introduction

The Tornado TM Lighting Enclosure

Thank you for purchasing the original Tornado Lighting Enclosure. We hope that this investment has paid off many times over, in preserving your expensive moving lights in a hostile outdoor environment. Now you have wisely decided to extend the life of your investment even further, by upgrading all the active elements in your enclosure(s) to the latest specification, and with a new 12month manufacturer’s warranty. This will at least double the life of your enclosure, at a far lower cost than replacing it

What’s in a Kit?

Your Tornado retrofit Kit provides brand-new parts to replace EVERYTHING on your original Tornado enclosure, excepting the fiberglass base and the plexiglass globe (replacement globes are always available – accidents can happen!). All metal parts and hardware supplied are 304 stainless steel, and marine-grade latches are included as standard.

Using This Manual

Please read this manual in its entirety before starting work. All the information contained is important, and should be read carefully before proceeding. Heed all warnings and advisories.

Safety and Warnings

These warnings are for your protection. Failure to comply may result in serious injury or death.

Manufacturer assumes no responsibility for damages or injury incurred by misuse or mishandling of product.

Do not attempt to install or operate the enclosure before fully reading and understanding this manual

Never allow anyone who has not read this manual to open the enclosure or perform maintenance on the luminaire within.

Never leave the enclosure unattended when open.

Always make sure all bolts are tight and safety cables are in place after performing any form of maintenance on the unit.

Even after power has been disconnected from the unit, it is likely that the heater will remain warm. Do not touch it unless you can be sure that the heater has been off for at least one hour.


e all posted warnings in the enclosure itself.


Do not open any electrical boxes until power has been shut off to all supply lines to the enclosure (including the one powering the luminaire).


Do not open the enclosure in wet weather.

Handling the Enclosure

In order to preserve the integrity of the Tempest Enclosure, care must be taken to prevent damage.

Following these simple guidelines will ensure that damage is not incurred in normal conditions.

Never move the enclosure with the luminaire inside.

Never handle the enclosure by the globe.

Always lift from under the base.

Tornado Enclosure User Manual page 5

1. Remove the Enclosure from the Installation Site

This upgrade must be performed by an authorized Tempest Lighting service representative in order to qualify for the 12-months warranty from the date of re-installation on site. The work may be performed by trained technicians, using normally-available hand tools. Tempest

Lighting strongly recommends performing the upgrade in a workshop, and not on site.


Do not open any electrical boxes until power has been shut off to all supply lines to the enclosure (including the one powering the luminaire).

1. Open the original enclosure and remove the luminaire for separate service/cleaning

2. Open the Existing DEC cover in the base of the enclosure and disconnect power feeder wires. Note whether the enclosure is fed with a single or dual supply (one feed for the enclosure, one for the fixture). If so, identify and tag wires correctly for re-installation.

3. Disconnect DMX wiring entering the enclosure

4. Remove electrical fittings under enclosure (they will not be re-used) and disconnect feeder conduits

5. Remove the mounting hardware attaching the Tornado Unistruts to the installation, and carefully remove the Tornado base. DO NOT ATTEMPT TO DO THIS WITH FEWER THAN TWO


2. Strip down and Update the Top Assembly a. Back in the shop, strip down as follows b. Top Assembly – do not remove the globe from the top fiberglass ring unless the globe is damaged. In this case refer to instructions below for replacing globe.

Check the silicone seal around the globe and clean out and touch up as needed. c. Remove the four latches and hardware and discard. d. Remove the existing rubber seal around the top ring and discard. e. This is a good time to CLEAN the top assembly – use mild detergent and no abrasives. Use a proprietary acrylic polish to take any minor scuffs out of the globe. f. Carefully install the new rubber seal, tapping home with a rubber mallet, and cut to length with metal shears. Glue join with outdoor-rated silicone. g. Mount the four top marine latches (they have three mounting holes) to the top ring.

Note that the stainless/rubber cone washer sits under the latch plate, and with its rubber side to the fiberglass, to prevent water ingress.

3. IMPORTANT – check the height of the fixture brackets a. Measure from the inside of the base (fiberglass) to the top of the two Z-brackets that support the fixture (they’re bolted down onto the DEC box). Make a note of this dimension – the retrofit kits are universal, and you’ll need to adjust the height later.

Tornado Enclosure User Manual page 6

4. Strip down the bottom Assembly a. The only parts you will be using from the base of the Tornado are the two fiberglass shells – so tear everything else out! b. Open the top of the DEC cover to access the Unistrut bolts, and remove them c. Remove all fans, using a Philips #2 screwdriver (note that the new fans are

208/230VAC, and the old ones are 24VDC – they are NOT compatible)

5. Replace the Neon Indicators a. Locate the two short cables connected to the DEC box, and cut off the Molex connectors with wire cutters b. Remove the neons from the outside, pull the wires through and discard. c. This is a good time to CLEAN the two bottom fiberglass moldings. d. Replace the Neons with the 1” x

5/16” hex bolt kits (shown here).

MAKE SURE THE Rubber side of the cone washer is under the bolt head and conforming into the fiberglass exterior, to assure a good seal. They should look like this…

6. Install the Bottom marine latches, with the studs facing UP, and using two #8 screws, Note that the stainless/rubber cone washers sit under the latch plate, and with their rubber side to the fiberglass, to prevent water ingress.

7. Prep the Retrofit Assembly a. Remove the stainless steel DEC cover, taking care to disconnect the control panel, and set it aside b. Check that all internal connections are positive and that nothing has obviously come adrift in transit c. Ckeck alignment – Make sure that the two conduit entry holes in the base of the retrofit kit will line up with those in the fiberglass BEFORE attempting to install the kit. We’ve all done it twice, and once is way better!

Tornado Enclosure User Manual page 7

8. Assemble the Base a. Insert the ½” socket cap screws up through the two unistruts, and press a rubber washer onto each one b. Now set the bottom and middle shell fiberglass moldings on the threads. The rubber washers should keep the screws in place, but this is much easier with two people. The holes should all line up. If they don’t, use a 9/16” drill to ease open the fiberglass. c. Set the retrofit kit in place on the four bolts – making sure before you tighten anything down that the two conduit entry holes line up. d. With everything aligned, drop a flat washer, a spring washer and a nut onto each of the four socket cap screws, and tighten down.

9. Referring to the note you took earlier, adjust the height of the fixture bracket and bolt firmly in place using the four sets of hardware provided. If you’re using a different fixture than before, adjust so that the fixture wasitline is approximately at the level of the

‘equator’ of the globe.

10. You’re essentially done. Time to test the system. a. Connect a 200-240VAC supply to the power terminals (details in Section 3 –

Wiring). b. Replace the DEC cover, making sure to reconnect the DEC display. c. Switch on power. You should see: i. The DEC display comes to life, showing temperature and humidity ii. Both lamp LEDs should be off iii. The fans will spin for a couple of seconds roughly every 30s iv. The heater will get warm, but not hot d. Now plug a lamp load (almost anything will do – say 500 to 1000W, 208/230V) into the L6-20 fixture receptacle, at which point the heater will go off, the fans will run continuously, and the lamp relay and lamp on indicators will light. Unplug the load to revert to background ‘pulse’ mode.

11. IF you determined that the original installation used two supplies (one for the fixture and one for the enclosure) then go to the wiring section (3) and follow the procedure for splitting the feeds to the DEC3 terminal block.

12. The original Tornados did not support DMX or RDM. The retrofit kits are supplied set up for

Standalone Operation, which emulates the way Tornados originally worked. Like the original product, this one should just plug in and run. If you want to use the more advanced features available, please study the DEC3 control section in this manual.

Tornado Enclosure User Manual page 8

Re-installing the Tornado Enclosure on Site


The following must be observed when re-installing the enclosure following retrofit:

Before starting the installation of the Tempest Enclosure, you must prepare the location, the luminaire and the enclosure itself.


Before beginning, it is necessary to decide how the enclosure will be mounted. These considerations must be taken into account.

No part of the enclosure should fall below two feet above the average snowfall for the area. If snow is not a consideration, then enclosure may sit on ground as long as proper drainage is available.

Enclosure will need to be powered at all times, although fixture may not be.

Tools and Equipment

To install the enclosure, you will need the following items:

Two people to carry out the installation. Warning: This installation cannot be safely completed by 1 person.

Crescent wrench

Phillips screwdriver

Proper wiring installation equipment (for line power and DMX)

Any equipment listed in the fixture manufacturer’s fixture-specific installation directions

Reinstalling the Tornado Enclosure

Normally enclosures that have been upgraded as instructed here will be returned to the same location and mounts where they were originaally installed. If that is the case, it is only necessary to verify the structural integrity and condition (eg rust) of any structural components and hardware, and to replace or remediate any problems found.

Tornado Enclosure User Manual page 9

Base Down and Base Up Mounting

Tornado 2000, 2200 and 2300 enclosures of the original fiberglass design may be installed either base up or base down. Enclosures used in the base-up orientation must have an open 3/16” (5mm) weep hole at their lowest point, to preventany water penetrating through the filters from ponding in the bottom of the globe. This does not affect thermal performance.

Base-down – no part number suffix, no weep hole in globe.

Base up – weep hole at globe’s lowest point.

Tornado Enclosure User Manual page 10

Wiring and Control



All electrical work must be carried out by a properly licensed electrician, in compliance with local electrical standards. Failure to observe this point will void the factory

warranty for the Tempest Enclosure.



Switch off power to the branch circuit, carefully following lockout and tag-out procedures.

Failure to do so could cause serious injury or death.

You will need two electrical junction boxes, located within a short distance from the enclosure, one for power, one for DMX control. Use outdoor-rated flexible conduit between the box and the enclosure.

AC and control circuits must be wired in separate conduits.



Flexible Conduit

120VAC, or

208VAC or

One or Two Power Circuits?

1 1 2

Single Feed Split Feed

Tempest enclosures may be wired on single or double line supplies. On a single feed, both enclosure and luminaire are permanently on. With a double-line supply, you can switch off the luminaire when not in use, while the enclosure continues to protect it 24/7.

Single Feed

Enclosure and luminaire are permanently on.

Enclosure and Luminaire must be rated for the same voltage.

Supply must be rated for luminaire current plus 150 watts.

Supply must be permanently ON.

Split feed

Enclosure power must be permanently ON.

Luminaire power may be switched off.

Enclosure power must be rated for 1150 watts.

Luminaire power must be rated for the luminaire (see luminaire manual).

Luminaire and enclosure power must be same voltage.

Either way, the enclosure must be powered 24/7, in order to protect the luminaire inside against condensation and extremes of temperature.

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.

Tornado Enclosure User Manual page 12

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.

Digital Enclosure Control – DEC3.2


Heater Fan On


Relay Temp DMX




– 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 killer of outdoor equipment. DEC3.2 monitors internal temperature, humidity and lamp current at all times, and uses this information to control the enclosure’s 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 or later.

Factory Settings – Basic Mode

In most applications, DEC3.2 will operate correctly with its factory default settings, in Basic operating mode.

You do not need to do anything. Please skip to the Power Connections section below.

If your needs are more complex, read on.

Tornado Enclosure User Manual page 18

Operating Modes

DEC3.2 may operate in one of four modes, set using either the Front Panel or by RDM control. In all configurations, the luminaire inside the enclosure may also be an RDM enabled device.

Basic Mode (factory setting)

 Standard temperature settings

 DMX and RDM disabled

Best for standalone operation

Monitor Mode

As Basic mode, plus:

 RDM status reporting

RDM configuration – settings may be changed remotely or at the enclosure control panel

DEC3.2 does not require a DMX signal to operate

Control Mode

As Basic mode, plus:

 Enclosure functions as a 1-channel DMX device, with remote control of the lamp relay o

DMX level > 75% enables normal relay operation (normally ON) o

DMX level < 25% disables normal relay operation (relay turns OFF) o

This allows you to force a hard reset of the lamp relay in the event of a luminaire malfunction

Control mode is recommended for show control applications, but can be risky in live show operation.

Service Mode

For trained service personnel only

 Normal operation is suspended and the enclosure functions as a 3-channel DMX device: o

Lamp Relay o

DEC3.2 Control Parameters

Temperature Settings:

Lamp relay open – Lamp OFF

Cutoff Temp

Range 0-15°C, Default = 15°C

Over-temperature Warning, Fans on

Top Set

Range 35-45°C, Default = 40°C

Normal operation

Bottom Set

Range 0-10°C, Default = 10°C

Under-temperature Warning, Heater on, Fans off


1 The Cutoff Temperature is an incremental temperature range above the Top

Set temperature. So the default 15°C cutoff and 40°C Top Set means that the lamp relay will open when a temperature of 55°C is reached.

2 In moving light enclosures the temperature sensor is located in the exhaust airflow. Temperatures shown may be higher than those around the luminaire.

3 We recommend using the factory default settings for several weeks or months before making any changes. In most cases they will not be necessary.

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.

Fan Overrun

Range 1-15 minutes, Default 5 minutes

Time that the enclosure fan(s) will run after the fixture/projector lamp is turned

Temp C/F off.

Display Degrees Celsius or Fahrenheit. Default Celsius

Note that temperature settings must always be Celsius.

Lamp Hours

Default 0000

Counts lamp hours – you must reset to zero when changing lamps.

Tornado Enclosure User Manual page 20

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.

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 enclosure lamp relay over DMX

DMX Terminations

Pinout: (1) Ground, (2) Data -, (3) Data +.

DMX Connectors:

DMX OUT to luminaire (or to network if not controlling luminaire)

DMX IN from outside world


DMX IN from luminaire


DMX OUT to network

If the enclosed fixture does not use DMX, then connector (2) on the controller is

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.

Tornado Enclosure User Manual page 21

Remote Device Management (RDM)

RDM refers to ANSI E1.20, a control protocol in the entertainment industry used for device configuration and monitoring, 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. The user must ensure that any DMX splitters or other routing devices used are rated for

RDM as well as DMX use. Tempest strongly recommends working with a qualified RDM system integrator when designing an RDM network. Go to

for contact information.

RDM and RDM Integration

DEC3.2’s RDM implementation allows system integrators to set up remote control and status monitoring of all attributes and sensors, including:

Relative Humidity

Air Temperature

 PCB Temperature

 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

RDM is an effective and powerful tool for commissioning and monitoring an installation, particularly in large systems. For further guidance, please consult a qualified RDM system integrator. 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.

Enclosure must receive power at all times. It is an active, climate-controlled enclosure, and will not provide proper protection for the luminaire inside if it is not connected to AC power.

Unless the enclosure or luminaire is undergoing routine maintenance, the globe should be in place and locked down at all times.

Only authorized personnel should open the enclosure (see maintenance warnings in the next section).

If the ambient temperature is high enough, the over-temperature shutdown feature may engage and temporarily cut off power to the luminaire. Once the temperature reaches acceptable levels, power will be automatically restored.

Do not routinely operate luminaire in full sun in warm weather. Black luminaires absorb a significant amount of energy from the sun and may overheat in these conditions. The enclosure has not been designed to protect the luminaire when running in this kind of extreme condition

(outside lighting is generally used at night).

Tornado Enclosure User Manual page 31

Routine Maintenance

It is very important to perform routine maintenance on both the enclosure and the luminaire within. Failure to do so may reduce lifetime for both the enclosure and the luminaire.


Maintenance schedules depend on location and environment. The times given here are general guidelines for you to use. It is up to you to judge whether maintenance should be done more often. We do advise doing these tasks no less often than mentioned here.


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 heater will get hot and the fans will start to turn. Make sure that your hands are clear of these areas 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.).

Be aware that the globe is a large object that can be awkward to handle, especially when standing on a ladder or scaffolding.

Inspection Checklist: - Every Three (3) Months

All weep (drain) holes should be clear

All vents should be free of debris

Enclosure should be free of debris both inside and out

Bolts should be tight

All safety cable should be in good condition

Lid seal should be in good condition, Check seal inside and out for gaps.

Globe should not be cracked

Fans should be moving (it will be necessary to have the power on to check this), with corresponding indicator status

Except for the last two items (concerning globe and fan), problems with any of these things can be easily remedied. Contact technical support for problems with the last two items.

Tornado Enclosure User Manual page 32

Air Filters - Every Three (3) Months

The air filters all around the base should be removed and cleaned on a regular basis. To remove filters, pull them directly out of their grooves. The filters can be cleaned by running water from a hose and do not require any special solution.

To reinstall, push filter back into place between the top and bottom base covers.

Case and Globe - As Needed

The outside of the case and globe should be cleaned as needed. Outside inspection should give you a good idea of when this is necessary. 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. The globe can be cleaned with any mild cleaner. It is also acceptable to treat globe with a product that keeps rain from adhering to its surface.

DO NOT USE hydrocarbon-based cleaners on the globe under any circumstances. They can severely damage the globe material.


Review the manufacturer's instructions for proper maintenance of your luminaire. Remember, the enclosure simply protects the luminaire and is not a substitute for regular maintenance.

This is a guide to the general symptoms, problems, and solutions that may occur during the lifetime of your enclosure. However, it is important to remember that problems may occur within the luminaire itself and these must also be considered.

Luminaire does not have power.

Check power switch of luminaire. (Note: the following actions should be performed by a licensed electrician) If power is on, check wiring (including metering supply voltages, enclosure must receive 200-240VAC to operate properly). If LEDs on the DEC3 control panel controller are lit, check the Lamp Relay LED. If it is on, meter power in receptacle. If no power is present at the receptacle, contact technical support.

In case of over-temperature, the power disconnection is an intended function of the enclosure and is for the protection of the luminaire, which is not meant to operate in extreme conditions.

In this case, the problem will only continue until temperature drops to acceptable levels. 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.

Luminaire turns on and off repeatedly

Check that vent areas and airways are clear. If so, ambient temperature may be too high (see over-temperature note above) or luminaire may have internal problem.

Luminaire does not respond to DMX signal.

Make sure that luminaire has power. If so, check DMX wiring. If not, see above.

Fans are not spinning.

Fan cords may have become disconnected. Check connections between fan and cord.

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.

Excessive debris in unit.

Filter may not be fully pushed into groove. Make sure that it is in place around the whole unit.

Excessive water in enclosure.

Weep (drain) holes may be clogged. Clear them.

Latches do not latch properly.

Closure of globe may be obstructed. Check to make sure seals are clear before replacing globe.
