Desklamps Not Working - Event Plus 60/120

[Yellow_Fuzzy]

Hi,

I recently purchased 2 Three pin desklamps from Jaycar(http://www1.jaycar.com.au/productVie...Max=&SUBCATID=) but i have been unable to get them to work on an Event Plus 60/120, i checked the voltage seemed alright, tried rewiring one of the lamps and it still wouldnt work, i have checked in the setup adn the lamps are set on. Any suggestions any one has would be appreciated.

Regards,

It is most likely that the lamp is using different pins to the desk. For instance, the lamp may be wired between pins 1 and 2 and the desk may be supplying voltage to pins 2 and 3 (or any variation of).

First thing to do is turn on the lamp and them meter between the pins on the lamp to find out which pins are connected to the lamp.

Then check which of the pins on the desk are supplying voltage (if you cannot remember from when you checked it before).

If there is a mismatch between the configurations, you will have to see if you can modify the lamp (or the desk) whichever you feel is the easiest.

I had to rewire one a few years ago due to this.

Also, just check that the actual bulb is ok. You would not be the first person to buy a faulty bulb.

Just another thought, am I correct in thinking that the Event + desks allow you to dim the desk lamps? If so have you checked to see that the setting for this has not been dimmed down or turned off?

I already tried rewiring one to what should match up with the desk. I did check that the desklamps were set at full on the console. Would anyone know if it is possible to find the desks pinout in any of the events manuals?

Simple way is to use a multimeter (or even a 12V globe and 2 wires) to find which 2 of the 3 pins send the voltage to the lamp.

If you don't have the means to check this, PM me your email address and I can send you the service manual once I get into the workshop.

Other than that, www.jands.com.au would have a .pdf copy of the user manual, which may list which pins carry the voltage to the lamps.

BTW - since you are shopping at Jaycar, are you in Aus or NZ?

Thanks Mayhem, ill PM you my email address, I had a quick look through the user manual and couldnt find anything. I am in Sydney, Australia.

while we are on the subject of desk lamps... did either of you two see the new LED Littlelite's and Entech this year? they are pretty awesome, 3 white LED's and 2 red LED's - the white was too piercing apparently and the red helps ballance it all out, but you can customize it, and have just red or just white hahaa...

i have a jands event 48 and 24 desks, they both have the original desk lamps that came with them however i had a desklamp from jaycar also for my sound desk and it just would not work on the event, it had the same wire up and all... i dunno what the deal was, worked alright on the sound desk.. maybe events dont like jaycar :P

while I can understand that you might not want to buy a authentic littlelite, they are a bit in the pricy side... give jands a call and see how much theirs are... from memory they were about 60bucks or something... compared with a 120buck little lite

Yellow_Fuzzy - did you meter the board output for the desk lamp?

I found out today that there is a common fault with the desk lamp output on these boards as the control circuit often blows. The simple mod is to lift the 12V wire from the lamp dim pin on the CPU board (bundled in with the connector marked power/Lamp) and solder it directly to the 12V pin on the power output.

The disadvantage here is that the lamp cannot be dimmed from the desk any more.

My advice - meter the output pins 1 (Gnd) and 3 (12V) first and see if this is the case. If you have other lamps that are working correctly, then this is not your problem.

good work mayhem.. maybe you will have a solution to this..

on one of my events, when you set the desklamp to FF (Full) it dims right down to about 20%, however when you put the lamp onto 99% it runs at full kick.

its a good problem, will keep you occupied for a while, its got me beat!
