5 Troubleshooting 

Troubles Possible 

causes 

Corrective 

action 

No RELEASE after having 
switched on the ELC. 
Relay RELEASE open 

The ELC is not provided 
with operating voltage 

Check fuses and voltage of 
terminals 

 

Lamp is switched-ON 
(control input START at 
HIGH) 

Switch-OFF lamp 

 

Fault in ELC 

Contact manufacturer, 
see 5.1 

Lamp is too hot 

Let lamp cool down, increased 
cooling probably required 

Lamp does not fire after being 
switched on, and the relay 
RELEASE opens 

Lamp not connected 

Check plug contacts between 
ELC and lamp  

 

Lamp defective 

Replace lamp
