Why will my new lighting console not control my existing Colortran ENR or Leviton Topaz Dimming System? You need a Leviton IF501 Converter!

This blog is designed to help the end users of Colortran ENR and Leviton Topaz Dimmer Rack Systems understand how their dimmer racks receive their commands to turn on, off, and dim their lighting loads.  The first thing to understand is that the Colortran ENR, NSI ENR, and Leviton Topaz are all the SAME dimming system; just different names.  I will use Colortran ENR in the rest of this blog, but they are all the same.

enr-24-dimmer-rack-pic

The Colortran ENR Dimming System was developed in the 1980s and was being developed at the same time as the lighting industry was going from proprietary protocols of communication between lighting consoles and their dimming racks to a universal standard.  The universal standard is USITT DMX-512.  However, at that time period (1970-1980s) each manufacturer had their own protocol and Colortran was no different.  Colortran used a protocol called CMX.

DMX (universal language) and CMX (Colortran) are VERY similar protocols, but they are NOT the same.  You can use DMX to control a CMX controllable dimmer rack, but you will have flickering in the levels and random lights turning on and off.  Since you don’t want that to occur, you must make sure to use the correct protocol.

Back to the Colortran ENR Dimmer Rack, which is very unique in that the dimmer rack is “auto-sensing” and will accept either CMX or DMX.  The Dimmer Rack defaults to CMX if no control signal is present upon power up of the dimmer rack.   This is problematic, because most lighting consoles, barring those made by Colortran (built in CMX), use DMX (the universal language).

This means that if you use a “modern day” lighting console, the lighting console will output DMX, which will partially work with the Colortran ENR Dimmer Rack, but will not fully work with the dimmer rack.  Hence, you will have flickering and other random lights turning on and off in the system.

There are two solutions to this issue:

  1. Whenever you turn on your lighting console with DMX output, go and hit the “reset” buttons on the dimmer racks.  The Colortran ENR Dimmer Racks will see the DMX and will “auto-sense” to the DMX receiving mode.  This will ONLY last as long as the dimmer rack has power.  For example, if you turn off the lighting console, go home, and somewhere in the middle of the night, you lose power.  The Colortran ENR Dimmer Rack WILL revert to CMX control signal.
  2. The LEVITON IF501 Converter is the BEST solution.  The Leviton IF501 converter will convert the DMX input signal to the CMX output signal that is going to the Colortran ENR Dimmer Rack.  The Leviton IF501 Converter is simple to install and can be installed next to the lighting console.  All you need is the Leviton IF501 Converter, a power supply (comes with the unit), and a short DMX Control Cable (the standard is 5 pin, but 3 pin is possible).  Once the Leviton IF501 Converter has been installed, you will no longer need to reset the dimmer racks prior to using the system, because the dimmer racks will remain on their default CMX control signal.  This unit is available at our website store, click HERE for link.

leviton-if501-converter

In addition to the two solutions listed above the Leviton IF501 Converter is also able to go from CMX input to DMX output.  You might ask why this would be important.  The answer is that a lot of Colortran ENR Dimming Systems use an architectural control system called Viewpoint, which can output CMX, but not DMX.  If you install the Leviton IF501 after the Colortran ENR Dimmer Racks, then you can control DMX controllable lighting fixtures with the Viewpoint Architectural Control System.  This unit is available at our website store, click HERE for link.

Next, the Leviton IF501 Converter can be used to convert from DMX input to AMX output.  This would be used whenever you want to use a modern DMX Lighting Console to control an older version of Strand Dimmer Racks.  The older versions of Strand Dimmer Racks used AMX as their proprietary protocol.  This unit is available at our website store, click HERE for link.

Finally, the Leviton IF501 Converter can be used to convert from multiple languages to other languages such as RS232 to DMX, Leviton Lumanet I to DMX, DMX to Microplex and a several additional languages.  This unit is available at our website store, click HERE for link.

The Leviton IF501 Converter is a work horse of a converter in a very small package, which can help to solve a whole lot of issues in the lighting controls field.  If you have a specific application that is not described in this blog, but you want additional help, please contact our office for technical support at 1-866-457-5937 or contact us at info@goknight.com.

Microlite (Musco) Lighting Controls Retrofit – Heinz Field Case Study

Musco Lighting’s Microlite 1000 Relay Control System at Heinz Field Retrofitted with Intelligent Lighting Controls (ILC) LightLEEDer Retrofit Control System by Knight Sound & Lighting

August 2016; Cuyahoga Falls, OH – Knight Sound & Lighting announced it has recently completed a lighting controls retrofit for PSSI Stadium Corp’s Heinz Field Stadium, home of the NFL Pittsburgh Steelers and the NCAA University of Pittsburgh’s Panthers Football teams.  The controls retrofit occurred throughout the entire arena, replacing the outdated and unsupported Musco Lighting Microlite 1000 relay controls with a new cutting-edge Intelligent Lighting Controls (ILC) LightLEEDer relay system.  The ILC LightLEEDer retrofit panels are fitted into the existing Microlite panels and utilize the existing line and load wiring, allowing for a much faster and much less expensive retrofit process.  Knight Sound & Lighting pioneered the ILC LightLEEDer retrofit as a time-saving and cost-effective means for facilities to update to a relay control system with strong technical support, ongoing technological updates and custom graphics controls including Android (available now) and iOS (coming soon) Mobile App accessibility.

The system was installed and commissioned over a period of 8 weeks (July-August 2016) by Knight Sound & Lighting technicians Ed Gurski and Mark Knight working in conjunction with Heinz Field’s in-house electricians.  Under Knight Sound & Lighting’s guidance, a crew of two of Heinz Field’s certified electricians removed the old Microlite 1000 relay and electronic insert panels and installed the new ILC LightLEEDer relay and electronic insert panels.  Knight Sound & Lighting provided the lighting control programming, created the custom graphics screens, and performed the system energization. Throughout the process, the site retained full access and functionality for all of its lighting.

The project was facility-wide and included retrofitting 40 Microlite panels with 40 ILC LightLEEDer retrofit panels.  These relay panels control the lighting for the playing field, suites, concourses, exterior, offices, corridors, signage, emergency lighting, and bathroom lighting.

Heinz Field was interested in replacing the Microlite system because the aging system is no longer manufactured and parts replacements are becoming obsolete.  Furthermore, there are no longer any updates being made to the Microlite software and the time clock function will not run beyond 2025. In addition, Microlite relay systems require computer control and are only compatible with Windows XP or earlier operating systems.  This means there is no access to the security features and functionality offered by Windows 7 or later platforms.  For these reasons, many facilities are looking to replace their Microlite System with newer lighting control systems that can operate using today’s technological platforms.

In the case of Heinz Field, the facility was looking for a new relay control system which would provide them with the same functionality as the Microlite 1000, but would also add control of DMX controllable LED lighting fixtures.  The stadium was also looking for updated lighting control graphics and wanted the assurance of running its lighting control system on the newest releases of Windows operating systems.

Knight Sound & Lighting proposed that Heinz Field install the ILC LightLEEDer Microlite retrofit product which would provide all of the new functionality that Heinz Field was looking to gain.  The ILC LightLEEDer controls work with Windows 7 and Windows 10 operating systems while providing more enhanced and detailed lighting control graphics.  The new system also allows for additional control options, including BACnet integration and Android (available now) and iOS (coming soon) Mobile App control.  It also provides for DMX input and output, low voltage switching and touchscreen control.

In researching its options, facilities management found that the only real alternative was a complete system replacement. This involved the costly and labor-intensive process of entirely removing the old panels, removing conduit throughout the facility and running new wiring as needed.  For a facility the size of Heinz Field, the replacement process would have taken approximately 4 times as long as the retrofit option, costing the operation critical downtime and a significant increase in labor hours.

The ILC LightLEEDer retrofit with Knight Sound & Lighting was extremely appealing to Heinz Field because the existing 40 panel system could be retrofitted and operational in approximately 4 to 8 weeks while simultaneously allowing the continued control of the lights during the transition period.  During the weeks when the Microlite system was being converted over to the ILC LightLEEDer system, both systems were in use and operational at the same time.  Consequently, Heinz Field was able to continue to control all of the lighting throughout the facility without any downtime, including hosting a number of scheduled major events that went off without a hitch.

As one of the premiere football stadiums and concert arenas in the country, Heinz Field identified a way to make a critical update to its operations while balancing cost with technology.  Knight Sound & Lighting’s ILC Retrofit has provided the advanced functionality and integrations that the site was looking for, while minimizing cost and down-time.  The arena looks forward to making the most of a customizable system that will be supported now and in the long-run.

BENEFITS OF THE ILC LIGHTLEEDER MICROLITE RETROFIT SYSTEM

  • Large cost savings due to quicker installation
  • Easy transition due to similarities between ILC and Microlite systems
  • Advanced and better looking graphics screens
  • Compatible with Windows 7 and Window 10
  • Compatible with DMX controlled LED lighting
  • Ability to control via Android app (available now)
  • Ability to control via Apple iOS app (coming soon)
  • Ability to be networked via BACnet or BAS system
  • Compatible with Ethernet connection

COST SAVINGS ACHIEVED:

  • Re-use existing enclosures
  • Re-use existing cabling and conduit
  • Re-use any existing low voltage switching (if applicable)
  • Reduced downtime/potential loss of income in comparison to a full replacement system
  • Reduced labor time and installation cost
  • Energy savings achieved with a more efficiently operating system which fully utilizes time schedules and BAS systems

Is there a way to backup the memory of a Colortran Viewpoint Control System? Yes-EEprom Memory Card!!

Do you have a Colortran Viewpoint Control System controlling your Colortran ENR Dimmer Rack Lighting System?  If you do, then your Colortran Viewpoint Control System is only as good as the battery (Lithium 3vdc), electricity, and/or a DOS Based Computer program for holding the progamming of your system.

Expanded_Control_Module_Front_91921__08033.1427901347.1280.1280

The Colortran Viewpoint Control System can also be called the Leviton Viewpoint Control System and/or the NSI Viewpoint Control System.

What is the Colortran Viewpoint Control System?  The Colortran Viewpoint Control System is an architectural lighting control system, which can control the Colortran ENR Dimmer Rack, as well as many other Dimmer Racks.  The Viewpoint Control System can have input from Control Stations (LCD, LED, and Entry Stations), Time Schedules, and a Lighting Console through CMX (Colortran Multiplex) or DMX (Digital Multiplex).  Three separate input sources, which all merge together in a highest take precedence basis (HTP) to control the dimmers and/or relays in the lighting control system.

When the Viewpoint Control System was originally commissioned by a technician, the technician would have used a DOS based Computer (Windows 95 or 98) to program the Dimmer (quantity), Load Types (dimming, non-dim, and the such), Control Stations (types and quantities), Presets, Time Schedules, and additional items.  This information was then sent to the Expanded Viewpoint Control Module, which processes all of this information (think a small computer) and turns on and off the lights to the appropriate levels.

The Expanded Viewpoint Control Module would then hold the programming of the system in place as long as the electricity flowed to the control module.  If the electricity failed to the Expanded Viewpoint Control Module, then the Lithium Battery (3 Vdc) would then hold the programming in the system, until the electricity was restored to the system.

However, if the battery failed (below 3vdc) and the electricity went out, then the only way to get the programming back into the system was with the DOS based computer.  Although, we (Knight Sound & Lighting Inc) have several Windows 95/98 computers for this very purpose, most people do not.

Hence, we need a better way to restore the programming of the Expanded Viewpoint Control Module.  There is a better way!  We have the Colortran EEprom Memory Card, which is a very fast and convenient way to reload the programming of the Viewpoint Control System in less than 1 second!

Viewpoint EEprom Memory Card

The Colortran EEprom Memory Card is installed in the memory card slot and is “written” when everything is GOOD with the system.  This process takes about 5 minutes to write the configuration.  The EEprom Memory Card can then be removed and stored in a safe place (some people leave it in the Memory Card Slot).

When the system loses the programming of the Viewpoint Control System through power loss, battery failure, and/or corrupt configuration; simply install the EEprom Memory Card in the Memory Slot and press “Read” Card.  The memory is reloaded into the system within 1 second and you are up and running again.

An important note is that the EEprom memory card contains all of the information, but can only hold one (1) set of programming information.  If you want different presets for different occassions, you will need to have two (2) EEprom Memory Cards for the two different sets of presets.

The EEprom Memory Cards are very resilient and last for a very long time, because they are “burned” memory.  This is a very stable form of memory storage and works very well.

At this time, Knight Sound & Lighting Inc offers the Colortran EEprom Memory Cards on our website store at http://www.goknight.com.  In addition, if you have any questions, please feel free to contact us at 866-457-5937 and/or via e-mail at info@knightsoundandlighting.com.

Leviton D4200 Control Station

The Leviton D4200 Control Station is a diverse control station for the control of dimming and relay systems that utilize Leviton’s LumaNet 3 Network.  The Leviton D4200 Control Station is capable of controlling up to 32 LumaNet Control Channels on “Zones.”  The Zones are then part of presets or scenes (same thing);  each zone is included in each preset at a level of between 0 and 100 percent (there is a exception, which is the excluding of zones from a preset.  Please ask if you have a question).

Leviton D4200

Leviton D4200 Control Station

The typical operation of the Leviton D4200 Control station is to program the zones at predetermined levels and record these levels into the scenes/presets.  When the operator of the Leviton D4200 Control Station wants a preset, he/she simply pushes a preset button and all of the zones go to their predetermined levels.  All of this can be programmed and/or re-programmed by the end-user at any time (no computer program is required).

Although the Leviton D4200 Control Station is limited to 32 zones, it is NOT limited to controlling 32 dimmers and/or relays.  Multiple dimmers and/or relays can be given the same LumaNet addresses, which will allow them to work together.

In addition, the Leviton D4200 can operate time schedules for the automatic turning on and off of the presets.

Another neat feature is the Sequencer, which allows for the playing back of presets/scenes in a sequence with a programmed time interval.  This means that an individual can turn on preset 1, wait 1 minute, then turn on preset 3, wait 2 minutes, and then keep going on from there in a total of 64 steps.

Typically, the Leviton D4200 Control Station is connected to a Leviton Dimmer Rack, such as the Leviton A2000 or I Series e Dimmer Racks, which have built in LumaNet 3 Network capability.  In addition, the Leviton D4200 Control Station can also be connected directly to Relay Panels, such as the Leviton Z-Max and Z-Max+ Relay Panels.

However, you do not need to worry, Leviton makes a converter that can take the Leviton D4200 Control Station to DMX (universal RS-485 control language), Ethernet, and several other options.

The Leviton D4200 is a great control station with a lot of options that work well in multiple lighting control applications, such as churches, meeting rooms, auditoriums, schools, and the like.

In addition, Leviton makes accessory control stations, which can access the Leviton D4200 Control Station as both wired and wireless control stations.  There is also an Audio Visual interface for RS-232 communication with the lighting control system from the AV Integrator.

As a response to the smaller lighting loads currently occurring in the lighting world of LED’s and Compact Fluorescents, Leviton has created the Leviton D4206 and other units, which have built in dimmers on the control station.  This is perfect for the lighting system with smaller lighting loads.

Knight Sound & Lighting Inc specializes in the initial programming of the Leviton D4200 Control Stations.  In addition, we can fix the Leviton D4200 Control Stations.  Finally, we can provide training on the Leviton D4200 Control Stations.

If you need help with the Leviton D4200 Control Stations and/or any of the commercial lighting control products of Leviton, please contact Knight Sound & Lighting Inc at 866-457-5937 or email at info@knightsoundandlighting.com.  We are an authorized Leviton service agency.

Fans Available for Colortran ENR Series and Leviton NSI Topaz Dimmer Racks

Do you have a Colortran ENR Dimmer Rack?  How about a Leviton Topaz?  Or even an NSI Topaz Dimmer Rack?  Did you know that all three of these Dimmer Racks are actually the same Dimmer Rack!  Yes, Colortan, NSI, and then Leviton all made the exact same Dimmer Rack, but called it different names.  In addition, Colortran could also be called Lee-Colortran and/or Panavision Colortran.

Any way you slice it, the Dimmer Racks are the same and all of them have a fan or fans that cool and maintain the airflow of the Dimmer Rack.  If the fan fails, the Dimmer Rack will not operate.  In addition, the larger Dimmer Racks (ENR 24 and ENR 96) have a “vein” switch in the fan, which monitors the speed at which the fan operates.  If the fan moves too slowly, the vein switch will not close and the Dimmer Rack will be disabled through the “airflow” indicator light (orange on the control module).

Colortran (Topaz) ENR 96 Fan

Colortran ENR 24 Fan

Can you prolong the life of the fan(s) on the Dimmer Rack?  Yes, cleaning the Dimmer Rack on a regular basis will prolong the life of the fan(s) in the system.  In order to clean the Dimmer Rack, use a shop vacuum and vacuum all of the openings on the Dimmer Rack.  Do NOT remove the components of the system during this process.  A second step would be to use a tankless air compressor (tanked air compressor can condensate and produce moisture) and blow air over all of the openings and let the fan pull the dirt out of the system.  This process should be completed every 6 months or so.  This should not be a long process, think 10-30 minutes, but it will help a lot.

In regards to the fan(s) operation, there are no user-serviceable parts inside of the fans.  As such, please do NOT try to lubricate the fan(s), which will only cause more issues, rather than helping the situation.

The fan(s) on the Dimmer Rack run anytime the lights in the Dimmer Rack are running and then for a period of time after the lights shut off (typically 3 minutes).  In some cases, the fan(s) were setup with a phantom control station to run the fan 24 hours a day, no matter the state of the lights.  In this case, you will want to clean your system more often, based upon the increased airflow.

Typically, if you listen to the Dimmer Rack, you will hear the fan(s) bearings start to fail by a loud grinding sound.  If this occurs, you should be planning to replace the fan(s) on your Dimmer Rack.  Remember, the Dimmer Rack will NOT operate without the fan(s) on your Dimmer Rack operating successfully, so plan accordingly.

At this time, Knight Sound & Lighting Inc is producing replacement fan(s) for the Colortran ENR Dimmer Rack, NSI Topaz Dimmer Rack, and the Leviton Topaz Dimmer Rack (same fans for all).  The fan(s) are different for the three (3) sizes of Dimmer Rack 12, 24, and 96.  We have all three (3) available for purchase on our website store at http://www.goknight.com.

Typically, most facilities will purchase the Dimmer Rack fan(s) from us and then install the fan(s) on their own.  However, we do offer Field Service Visits where we will come to your facility and replace the fan(s) for you on your Dimmer Rack.  In addition, we will check other items on your system at the same time and will be able to make recommendations for any other repairs that might be needed.

A Dimmer Rack fan will typically run for between 10 and 20 years.  The length of the fans life is dependent upon the fans use (lights on) and the cleanliness of the Dimmer Rack.

For additional assistance on your Colortran ENR 12, ENR 24, ENR 96 or NSI Topaz 12, NSI Topaz 24, Topaz 96 or Leviton Topaz 12, Leviton Topaz 24, and Leviton Topaz 96; please contact our office at 1-866-457-5937 or through email at info@knightsoundandlighting.com.

Replacement computers available for Microlite LMS-XP and Microlite LMS-95 Relay Panel Systems

Do you have a Microlite 1000 Relay or Controllable Breaker Panel System?  If so, you probably have either Microlite LMS-XP (Lighting Management Software) or Microlite LMS-95 on an older Windows Computer.  The Microlite LMS-XP and LMS-95 are basically the same operating systems for the Microlite Relay Panel System, however, the Microlite LMS-XP is designed to operate on a Windows XP Computer and the LMS-95 is designed to operate on a Windows 95 or 98 Computer.

Microlite LMS 95&XP Cover Image

Now that we understand the basics of the Microlite LMS Operating Systems, we will discuss your options when your existing Microlite LMS-XP or LMS-95 Computer fails.  As you may know, the Windows 95, 98, and XP Operating Systems are no longer actively supported by Microsoft.  However, that does not mean that you must upgrade or retrofit your system;  there are options.

At this time, we are able to provide fully refurbished Windows XP Desktop Computers that will run the Microlite LMS-XP lighting control system.  We have this option listed on our website store (www.goknight.com).  In order to provide you with a fully operational system, we will need your database file from your existing Microlite LMS-XP Computer.  The database is the LMSXP.mdb file.  Hopefully, you made a backup of this file, before your existing Microlite LMS-XP computer failed.  If not, we can rebuild the database, but this does take some time and additional charges will apply.

What if you have a Microlite LMS-95 Computer running your Microlite system?  We can also handle that situation, but it does take some more effort and expense.  You will also be able to purchase the Microlite LMS-XP Computer from us.  Just like above, we will need a copy of your database, but this time it will be the LMS95.mdb file.  Again, hopefully you made a backup of this file.  Next, we will either have to convert the file to the LMSXP.mdb OR reprogram the database with the information provided in the database file.

Why do we have to reprogram the database, you might ask?  Some LMS95.mdb allow us to just change the name of the file and it will work with no reprogramming.  However, sometimes, we have to recreate the entire database.  There is no easy way for us to determine this action, without having the database.  If we have to reprogram the database, then we will charge you a per hour fee for the reprogramming of the database.  The cost of the reprogramming is determined by the size of the system.

Can we use a newer Windows operating system, such as Windows 7 or Windows 10?  No, at this time, we are not able to install the Microlite LMS-XP Lighting Control System on those Microsoft Operating Systems.  The Microlite Software has NOT received any attention from Microlite for several years and there are no plans to work on it at this time.  Microlite was acquired by another company several years ago and the new company does not sell and/or create any upgrades for the Microlite Relay Panel System.

Some Microlite LMS Lighting Control Systems have graphics that allow the end user to operate and monitor the relays in the system through a graphical interface on the computer.  If your existing Microlite LMS Computer has graphical screens, we can put those on the refurbished Microlite LMS-XP Computer, but we will need additional files from your existing Microlite LMS Computer.  We will review those files on an individual basis.

If you system is an older Microlite System, it could have an operating system called Microlite Proteus.  This type of operating system required a DOS based interface to the system and worked through either an RS232 or Modem connection.  In this case, you can also upgrade to a Microlite LMS-XP Computer, but this would require a site visit and the Microlite NCM (Network Control Modules) in each Relay Panel may need to be replaced to communicate with the new computer.  Please contact us for specific information on this process.

MicroLite Proteus Panel Label

Is there a way to upgrade the Microlite Relay Panel System without having to replace the entire system?  YES, we have developed a Microlite Retrofit System which allows the replacement of the Microlite components, but keeps the existing Microlite enclosures and the high voltage wiring in the same spot in the Microlite enclosures.  This allows the end user to replace the Microlite Relay Panel Inserts with a new Microlite Retrofit and have a completely new system with a minimal amount of electrical work.  An entire system can be retrofitted in a minimal amount of time and provide the end user with a vast array of new features.  The Microlite Retrofit System is capable of using up to Windows 10 operating systems at this time and will be able to work with newer Windows operating systems as they are released by Microsoft.  In order to find out more information about the Microlite Retrofit System, please visit our website at www.goknight.com.

Leviton Dimmer Module Model 166-362 (Colortran ENR Dimmer, NSI Topaz Dimmer)

YOU CAN ORDER REFURBISHED UNITS OF LEVITON DIMMER MODULE MODEL 166-362 FROM GOKNIGHT.COM, AN AUTHORIZED LEVITON SERVICE AGENCY.

Are you looking to replace a Leviton Dimmer Module Model 166-362?  While these units are no longer manufactured new, you can purchase refurbished units of these dimmers from GoKnight.com (a division of Knight Sound & Lighting), which is an authorized Leviton service agency.  To purchase refurbished Leviton Dual Dimmer Module Model 166-362, please go to the following link:

http://www.goknight.com/categories/legacy-lighting/colortran-enr-colortran-topaz.html

 

THE LEVITON DIMMER MODULE MODEL 166-362 WAS ORIGINALLY MANUFACTURED BY COLORTRAN (OR LEE COLORTRAN), AND THEN BOUGHT OUT BY NSI CORPORATION AND THEN FINALLY BY LEVITON.

The original manufacturer of the Leviton Dimmer Module Model 166-362 was Colortran Lighting, which was based in Burbank, CA. During this time period Colortran was known as Colortran, LEE-Colortran, and even Panavision-Colortran.  The Colortran Brand was purchased by the NSI Corporation in Tualatin, OR, which produced both the Colortran Model (ENR) and the NSI Model (Topaz).  Both of these models are the same system.  Leviton Manufacturing purchased NSI-Colortran Lighting and absorbed the company many years ago, but was still based in Tualatin, OR.  Your dimmer module may even say “NSI-Colortran Division” (of Leviton) depending on the age of the unit.  Leviton has continued to support the Leviton Dimmer Module Model 166-362 through 2016.  The Leviton Dimmer Module Model 166-362 is no longer manufactured new, but can be refurbished by authorized service agencies, such as Knight Sound & Lighting (www.goknight.com).

THE LEVITON DIMMER MODULE MODEL 166-362 GOES BY MANY DIFFERENT NAMES INCLUDING 166-362, ENR DIMMER, TOPAZ DIMMER, ENR SWITCH, TOPAZ SWITCH, ENR DIMMER PACK, TOPAZ DIMMER PACK, ENR 2.4KW DIMMER, TOPAZ 2.4KW DIMMER, COLORTRAN ENR DIMMER, AND COLORTRAN ENR 2.4KW DIMMER.  FURTHOREMORE, THE MANUFACTURER COULD BE INDICATED AS LEVITON, NSI/COLORTRAN, COLORTRAN, NSI, OR LEE COLORTRAN.  THE MODEL COULD BE INDICATED AS ENR OR TOPAZ OR MODEL 166-362.

The Colortran ENR model line was eventually discontinued and replaced by the Leviton Topaz model line.  This means that ALMOST ALL of the ENR and Topaz parts are interchangeable.  For instance, the Colortran ENR 2.4kw dual dimmer module is the same as a Leviton Topaz 2.4kw dual dimmer module.  The Colortran ENR 2.4kw dual dimmer module is also known as model 166-362 or Leviton dimmer module model 166-362.  These dimmer modules may also be referred to as Leviton dimmers, Leviton dimmer packs, Colortran switches, ENR switches, Topaz switches, Topaz dimmer packs, Colortran dimmer packs, ENR dimmer pack, Colortran ENR dimmer, Leviton Topaz dimmer, LEE/Colortan Dimmer Pack, and Colortran ENR 166-362.

THE LEVITON DIMMER MODULE MODEL 166-362 CAN BE INSTALLED IN ANY OF THE FOLLOWING DIMMING RACKS:  ENR PORTABLE PACK, ENR 12 WALL PACK, ENR 24 DIMMER RACK, ENR 96 DIMMER RACK, NSI TOPAZ PORTABLE PACK, NSI TOPAZ 12 WALL PACK, NSI TOPAZ 24 DIMMER RACK, AND NSI TOPAZ 96 DIMMER RACK.

The Leviton dimmer module model 166-362 are used in the Colortran ENR Portable Pack, Colortran ENR 12 Wall Pack, Colortran ENR 24 dimming rack, Colortran ENR 96 dimming rack, NSI Topaz Portable Pack, NSI Topaz 12 Wall Pack, NSI Topaz 24 Dimmer Rack, NSI Topaz 96 Dimmer Rack, Leviton ENR/Topaz Portable Pack, Leviton ENR/Topaz 12 Wall Pack, Leviton ENR/Topaz 24 dimming rack, and Leviton ENR/Topaz 96 dimming rack.
