PLS 2016: Important ELEXON update: implementation of generic LED charge codes
Download as PPTX, PDF0 likes444 views
Elexon is implementing a new range of generic LED charge codes on 30th June to address the rapid increase in charge codes due to advancements in LED technology. These codes will standardize energy ratings across different manufacturers and help reduce charge code proliferation, while ensuring dimming options are accommodated through a new variable power switch regime. The transition will simplify integration into asset management systems and maintain validity for existing codes.
PLS 2016: Important ELEXON update: implementation of generic LED charge codes
- 1. Implementation of ELEXON Generic LED Charge Codes 16/06/2016 – ILP Summit
- 2. What will be covered? Background to the change Generic LED Charge Codes Variable Power Switch Regimes ELEXON Approved? Constant Light Output Impact on CMS Summary
- 3. 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 codes Originally a 150W SON ballast (standard control gear) had the same charge code irrespective of the manufacturer Then came electronic control gear and dimming Differences in circuit wattages between manufacturers and a desire for individual, manufacturer specific charge codes This was manageable for a while but the development of LEDs and 1 watt increments being available meant that the charge code list grew rapidly
- 4. ELEXON with the assistance of the Unmetered Supplies User Group (UMSUG), manufacturers and asset management system providers looked at a range of options Key customer desire was a reduction in ‘charge code proliferation’ Using the charge code spreadsheet itself and filtering not the issue per se Setting up the codes in the asset management system was an issue Agreed 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?
- 5. On the 30th June ELEXON will implement: A new range of generic LED charge codes These will all be the 100% power rating A separate range of ‘Variable Power Switch Regimes’ will be created for dimming Dimming will be in 5% bandings (n/a to CMS) A separate spreadsheet for checking a manufacturer’s approval Old codes will remain valid but no new ones will be published for LEDs outside the generic range Goes live this month… Implementation
- 6. 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 100 Digits 7, 8, 9 and 10 not currently used: 42 0060 0000 100 Should be easier to enter into asset management systems as logic to the code’s structure returns Generic LED Charge Codes
- 7. 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 levels VPSR 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
- 8. Number of manufacturers engaging with the charge code process has dramatically increased in recent years This list can be used to verify that a manufacturer is approved It lists the lower and upper wattage limit for each product Manufacturers will need to think carefully about having clear product descriptions so that they don’t become overly specific ELEXON Approved? Manufacturer Manufacturer's Designation Generic LED Codes – Lower Limit Generic LED Codes – Upper Limit ABC Ultra Product 1 42 0030 0000 100 42 0040 0000 100 XYZ LED Retrofit Superstar 42 0100 0000 100 42 0130 0000 100
- 9. Using generic codes in the inventory means customers can no longer use the charge code itself to identify the manufacturer May want to add a column to capture that information, presuming more than one manufacturer is used Alternatively may want to capture the specific model number to monitor faults with products, lamp life, warranty claims, etc… Identifying the manufacturer Many more…
- 10. 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 code CMS 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 CLO Enter the charge code for the wattage that is the midpoint between the start and end of life If 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
- 11. For CMS users there is no change Customers use new generic LED charge codes in inventories Continue to use switch regime 999 as before All dimming / part night switch off events captured by the CMS event log file in the background No need for 5% bandings for dimming Can dim to any % power supported by lamp / driver Central Management Systems
- 12. Generic Charge Codes available from 30th June Will greatly reduce number of charge codes needed All dimming will be declared using VPSR Dimming in 5% bandings (unless using CMS) Existing charge codes / dimming still valid Consider how to capture manufacturer information in inventories Need to understand if the CLO is controlled by driver or CMS Summary
