Zone VI Photocell & Receptacle to an Aristo VCL4500 2-tube VC head

<p>I just obtained an Aristo VCL4500 2-tube VC head. I have a Zone VI compensating timer and a new unused L702 Photocell & Receptacle, which is required to be installed on to the Aristo VCL4500 2-tube VC head to make it compatible with the Aristo head.<br>

I have instructions for attaching a Zone VI Photocell & Receptacle for a Zone VI Stabilizer Retrofit kit. However, I need the instructions for retrofitting the Zone VI Photocell & Receptacle to an Aristo VCL4500 2-tube VC head.<br>

Could someone provide me a schematic or some other information regarding how to accomplish this? After much reading on the Internet, I understand that I must make this modification to make the two items compatible. Your knowledge and experience is appreciated.<br>

After learning how to install the photocell, because it came with a faulty Zone Vi Enlarger Timer, which I have to return, I no longer have the photocell. I am now looking for a photocell. Actually, I have an email into RH Designs in England to see if they can provide me with a timer that will work with both my Zone Vi Light Head and the Aristo VCL4500 head. So, I am in a holding pattern now.<br>

Thank you for getting back to me.<br>

<p>Hello Luther, </p>

<p> I think RH Designs will be able to help you out, let us know. I love their fStop timer. My VCL4500 had a plug for the photocell, which plugs into the fStop timer, I'm surprised yours didn't. <br /><br /> Best, <br>

Thank you for the response. After reading your message, I re-checked my Aristo VCL4500. They did not ship with the retro photocell. Someone prior to you probably outfitted your light with the photocell. You are fortunate. A picture of the where the photocell wires enter your light head would be helpful.<br>

<p>Hello Luther, <br /><br /> I've been meaning to open mine up because it is my understanding is that the bulb is rectangular, and that it will cover 5x7, barely, and I mean barely. Could you verify that for me? Aristo used to make an adaptor for a Durst 5x7 but those are impossible to find. I'm going to have to have something made so I can use the VCL 4500 on my Zone VI 5x7 enlarger because I shoot 5x7. Once I get it open, or someone else opens it, I'll post a picture of the location of the photocell.<br>

I had to change a bulb in a different 5x7 Aristo head, and I recall that the photocell goes in the middle, with the sensor facing away from the bulb, I believe. There are instructions in the manual for RHDesign's fStop timer for where to put a photocell.<br>

Louise Kessler at Voltarc (Louise.Kessler@voltarc.com) is a wonderful help and will sell you new bulbs for the VCL4500. She won't have the photocell though, just the bulbs. <br /><br /> Best, <br /><br /> Larry</p>

These links will probably be very helpful. Before looking through the links, review the attached pdf<br>

file regarding the Aristo VCL 4500 modifications for 5x7. If you are handy with tools, this may be all you will need. Read the attachment first. Larry, I have a copy of the pdf, but I cannot locate a place to make the attachment here. The pdf is "vcl4500_adaption__to__zone_vi_5x7_enlarger_info..pdf." It should be some where on the Aristo site or it came with my Light head and I scanned it to my computer. I do not remember which. However, if I can figure out how to attach it to my messages, it solves your problem.<br>

The information is attached. I forgot that I can only upload a file after my written message is confirmed. I hope all of this helps.<br>

<p>Hello Luther, <br>

Yes, I have that document, now, I just need to get a bezel like that, there is nothing commercially available, as far as I know. </p>

<p> Larry</p>

<p>Larry,<br>

That bezel will have to be hand crafted, I know of no one who has ever made one. Yours may be a first.<br>
