ProfiLux3 + LEDControl4 + MeanWell LDD

[evgeny30ru]

I need technical assistance in connection DIY marine lamp through LEDcontrol V2.
Wiring diagram for an attachment. Just attach the DataSheet for drivers MW LDD.
Has a separate power supply for 48 and 5 volts. Load resistor of 1K.
The problem is the following, that a decrease in the level of the channel to zero does not disable the LEDs completely, and very weakly lit. What am I doing wrong? How to make a minimum level, they were switched off at all?
I hope very much for your help.

you need 10k pulldown resistors from pwm to gnd on LDDs

There supposidly there.. Diff version of the circuit..
listed as a puulup resistor..

It turns on my scheme, all right?
How to choose the correct resistor capacity?

If you lose connectivity between the drivers and the Arduino, your LEDs will run at full blast, which could potentially fry your corals. To resolve this, you can put a 10k pull-down resistor between the CTRL/PWM pin of the driver and ground, which would effectively turn the LEDs off.

That's the problem.. it should pull to ground (V-) not power (v +) .. I'm confused..
