Problems with full sim LED's

[bubbling-under]

I have a very strange problem with my GHL Profilux running full sim LED's
They work fine when connected to ports L1 / L2 but will not work when connected to ports L3/L4. I have configured illumination 3 for the Blue Moonlights and Illumination 4 for the Red sunset / sunrise LED's If I map I3/I4 to L1/L2 they work fine - if I map I3/I4 to L3/L4 they dont work ( not even if I try to manually light them using the sliders on the light scenarios. I find this very strange as there is very little congig on the 1/10v ports.

I do have a second L1 - 10V interface card in slot 1 - the LED's work also on these ports but there is no lightning effect ( I believe his is correct as he manual states that lightning is only available on L1/L2 and L3/L4.

I have been working with Steve at Reefdreams to get this resolved - I have tried defaulting the GHL and adding a config file that has been checked by Steve -unfortunately this failed to resolve the problem

I have also come across another problem with a 1-10v port on my GHL Profilux. Last night I noticed 1 of my Tunze streams was not working ( configured on port 5 as part of a pair on 5/6 using a GHL splitter )

This morning I have done lots of testing and tracked the problem down to the 1-10v interface !

Testing Completed:
Control cable removed from pump - pumps work ok
Control cable placed on another pump - pump stops
Problem follows control cable from port 5

I have as a temp measure, moved the pair of Tunze's to ports 7/8 and they are now working ok …

I am now completely stuck for ideas with both of the problems ….

it sound you are familiar with doing the settings and I have doubts if your settings are the reason for the problems

A simple way to test the interface is to set it to 1V and 10V and illumination x. Then you manually change the brightness. Now you should see a change of the voltage between 1V and 10V (1% ... 100%) and 0V at 0%. Can you check the interfaces in this way? During this test all illumination simulations (moon, clouds, rainy days) must be deactivated in order to obtain a sense making result, and ensure that the burn-in is not active for the illumination channel in question.

Hi Mattias - thanks for the response.. what would be the best way to complete the test... use a voltmeter.. or possibly use my dimmable T5's.
If I connect the T5's to the port that I am having problems with the Tunze's on (L5) then am I right in assuming that if I connect the T5's they should brighten and dim as the pumps would surge ?

The strange thing with ports L3/4 is that my dimmable T5's work ok on this port ( I guess they are connected to L3) however full sim LED's will not work on this port ! Do the Full Sim LED's use any additional control leads ?

Not sure how I can test L4 as the only device that I have that will work on the even channels 2,4,6 or 8 is a Tunze pump. I believe the T5's are configured to work on the odd channels 1,3,5 etc .

I am guessing that the best way to test the ports would be to make up a lead just for the purpose

The pin-out info I have is :
Pin Function Color
1 +12V - Black
2 Dimming intensity channel 1 - Brown
3 GND - Red
4 On/off channel 1 (relay control) - Orange
5 Dimming intensity channel 2 - Yellow
6 On/off channel 2 (relay control) - Green

Do you used standard western cables / sockets ? or would I have to get the test lead from GHL ?

Regards,

Paul

Hi

yes you can only test the odd channels with your T5.
The Simu uses 2 channels. What in the Simu does not work exactly? The red LEDs can't be turned on?
A voltmeter is necessary for a test.
Our western plug is standard 6p6c

If plugged into L3/4 neither the red or blue LED's will work - they work OK if plugged into L1/2....However the T5 will work in L3/4
Why his should be, I have no idea !

You can see my configuration in the following thread ...

(assuming a ref to Ultimate Reef is ok for this purpose ! )

I have no idea what this can be - please measure the voltage, we must consider that some of the L-ports died for some reason. Only after getting the measurement results I can do some diagnostics here.

Recently we had a case where defective electronics of the Tunze driver blew up some of our 1-10V circuits. Very weird was in that case that the problem in the Tunze driver occured not permanently, most time it worked well.

PS: A reference to Ultimate Reef is ok, this is an open and free forum.
