Currently charge code spreadsheet stands at 8,331 active charge codes, of these 6,315 (76%) are for LED lamps

(figures correct as of 1st June 2016)

Thousands of LEDs…

One of the most common issues raised by customers has been the ‘explosion’ of ELEXON charge codesOriginally a 150W SON ballast (standard control gear) had the same charge code irrespective of the manufacturerThen came electronic control gear and dimmingDifferences in circuit wattages between manufacturers and a desire for individual, manufacturer specific charge codesThis was manageable for a while but the development of LEDs and 1 watt increments being available meant that the charge code list grew rapidly

ELEXON with the assistance of the Unmetered Supplies User Group (UMSUG), manufacturers and asset management system providers looked at a range of optionsKey customer desire was a reduction in ‘charge code proliferation’Using the charge code spreadsheet itself and filtering not the issue per seSetting up the codes in the asset management system was an issueAgreed that using the same codes for different manufacturers was not an issue (40 watts is 40 watts)Concern over how to check for ELEXON approval

The Solution?

On the 30th June ELEXON will implement:A new range of generic LED charge codesThese will all be the 100% power ratingA separate range of ‘Variable Power Switch Regimes’ will be created for dimmingDimming will be in 5% bandings (n/a to CMS)A separate spreadsheet for checking a manufacturer’s approvalOld codes will remain valid but no new ones will be published for LEDs outside the generic range

Goes live this month…

Implementation

Charge code will always begin “42…”Will always be the 100% power version and therefore end “42 XXXX XXXX 100”Circuit wattage is contained in the charge code, so 60 watts is: 42 0060 0000 100Digits 7, 8, 9 and 10 not currently used: 42 0060 0000 100Should be easier to enter into asset management systems as logic to the code’s structure returns

Generic LED Charge Codes

All dimming will be reflected using the new Variable Power Switch Regimes (VPSR)Three digit alpha numeric switch regime, detailing the time(s) the dimming applies and the % power(s)Dimming is in 5% bandings, if dimmed by 22%, operating at 78% of full power, this would be rounded up to 80%If operating at 76% power, rounded down to 75%VPSR used for single step dimming and multiple dimmed levelsVPSR in effect a rebrand of the current Multi Level Static Dimming (MLSD)Cannot use a 500 Series switch regime with a generic LED charge code, must be a VPSR

Please note this VPSR list is not yet published, it could be any letter / number combination! Customers can request any dimming regimes they require

Variable Power Switch Regimes

Number of manufacturers engaging with the charge code process has dramatically increased in recent yearsThis list can be used to verify that a manufacturer is approvedIt lists the lower and upper wattage limit for each productManufacturers will need to think carefully about having clear product descriptions so that they don’t become overly specific

Using generic codes in the inventory means customers can no longer use the charge code itself to identify the manufacturerMay want to add a column to capture that information, presuming more than one manufacturer is usedAlternatively may want to capture the specific model number to monitor faults with products, lamp life, warranty claims, etc…

Identifying the manufacturer

Many more…

Need to understand if the CMS is controlling the CLO (or not)If CMS controls the CLO:

Enter the end of life circuit watt charge codeCMS will then register that it is operating at 70% power on day 1, 80% on day 600, 100% day 8,700(!)…

If there is either no CMS or the CMS does not control the CLOEnter the charge code for the wattage that is the midpoint between the start and end of lifeIf it is 100W at the start of life and 150W at the end then the charge code in the inventory would state 125W

Constant Light Output

For CMS users there is no changeCustomers use new generic LED charge codes in inventoriesContinue to use switch regime 999 as beforeAll dimming / part night switch off events captured by the CMS event log file in the backgroundNo need for 5% bandings for dimmingCan dim to any % power supported by lamp / driver

Central Management Systems

Generic Charge Codes available from 30th JuneWill greatly reduce number of charge codes neededAll dimming will be declared using VPSRDimming in 5% bandings (unless using CMS)Existing charge codes / dimming still validConsider how to capture manufacturer information in inventoriesNeed to understand if the CLO is controlled by driver or CMS
