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.
