Architectural Dimmer Internal wiring diagram..

Dear All,
From where I can get the Architectural Dimmer's internal wiring diagram?

Regards, Rakesh

 

Dear Ashleigh,

We are using Architectural dimmer with catalogue no : L5112D16B2

Regards, Rakesh.

 

Whilst we can't provide you with an internal wiring diagram, perhaps if you ask the right questions we will be able to give you the right answers? What is it exactly that you want to know?

 

Dear Newman,

My doubts are

# What is the function of the square box at the input side of the dimmer where we give the 3 phase input supply?

# Why the fan of the dimmer works when we remove the cable connector strip to the DSP card? How to isolate the fan?

# What the three wires connected to the dimmer PCB(Black, Red, Black) are for?

# Can we isolate the dimming procedure / units to make the Architectural dimmer to act just like a Distribution Board? I mean, by giving 3Phase supply to the dimmer can we take the outputs from the 12MCB's in the dimmer as a balanced single phase distribution? (We want to isolate the faulty dimmer and connect these circuits to a Relay).

# We are having problems with one of the channels of the dimmer, which leaks current to the load, makes them ON (not 100%, it makes buzzing sound also) even when we switch of the channel using the on board switch / Neo switch. Which of the component got issues? How to troubleshoot this?

# How to give a fail proof protection for the dimmer channels? I heard connecting MCB's at the load side is not effective.

# One of the dimmer in our installation is having problem with the DSP card, can you please provide us the source for the C-Bus items. We are situated in Middle east - Qatar. Can we source C-Bus units directly from Clipsal - Australia? What all the procedures and time it will take to dispatch these items?

Thanks and Regards, Rakesh...

 

This silver box is a noise filter. It gives a cleaner feed to the unit for better zero-crossing detection and also reduces the amount of dimmer-induced noise getting out onto the mains.

This is most likely because removing that connector disconnects one of the thermal sensors in the unit. The unit runs the fan to ensure that the dimmer doesn't overheat, even when a sensor has failed.

Can you be more specific?

Whether what you're trying to do is legal or not will depend on the wiring rules in your country. Modifying the internal wiring may void your warranty. Also note that the silver mains filter is only rated at the current of the dimmer channels. If you connect more than 12 x 12A on a 12A unit, any extra load will exceed the rating of the filter.

The dimmer, like nearly all dimmers, has EMC bypass capacitors across the channels. The minimum load is 150W per channel. Is it possible that you're under this load rating?

How to protect the dimmer channels is a complicated and non-trivial topic. It depends on wiring sizes, local regulations, source impedance, exact nature of the fault, type of MCBs fitted, etc. The architectural dimmer channels use very robust switching devices. I'm surprised to hear that channel MCBs is not sufficient.

The new C-Bus Infinity range of dimmers have individual channel cards, which allows servicing of individual channels. They also include a channel bypass switch which connects the mains directly to the output, bypassing the dimmer channel. These new dimmers are definitely worth looking into for your next project.

You will need to talk to technical support in your country.
