MBL1 Articulated LED Downlight

TECHNICAL

SPECIFICATIONS

MBL1 Articulated LED Downlight

Schematic Showing Driver & Splitter

Problem

Probable Causes

Test & Remedy

Constant Current System 

System is dead - no light 

output from LED’s

Mains supply off

Check supply and reinstate.

Loose mains plugs

Check plugs.

Loose DC output wire or 
connection

Check all connections.

Splitter LED channel not 
terminated

Check all splitter channels have LED  

fittings plugged in or have continuity 

jumpers fitted. Plug in LED’s and/or jumpers

Single failed LED

With power ON, carry out one of tests 

detailed in fault finding guide. Replace 

faulty LED.

More than one failed LED

Gradually replace LED plugs with 

 continuity jumpers until LED’s light. Do  

not  reduce the number of LED’s plugged  

into the splitter below the driver minimum

Driver failed

Check output with DVM. With power ON 

 and no LED’s lit, DC voltage output to 

 LED’s should be at maximum

Cable between driver and 
splitter failed

With power ON and splitter cover 

removed, put DVM across input to splitter. 

DC voltage input to splitter (allowing for  

volt drop in cable)  should be at 

maximum. If no voltage fault find and/or 

replace cable.

Constant Current System 

Some LED’s not working

Short circuit - damages cable 
between LED and splitter

Repair or replace.

LED short circuit

Replace LED and cable.

Constant Current System 

LED’s on full illumination 

- not dimming

Faulty or wrong connection at driver 
or dimmer control box

Check driver and dimmer connections. 

Replace/repair as necessary.

Faulty dimmer potentiometer or 
damaged dimmer control cable

Remove dimmer control cable from 

dimmer. Check continuity of cable and 

dimmer pot. Replace/repair as necessary.

Failed driver

Replace driver.
