Point that does not work well Ilford Head 500

Rmaydana · Sep 22, 2022

Punto que no funciona bien
1- El ventilador no se apaga en 2 minutos, al principio el ventilador se apaga pasado el tiempo en unos 2 minutos. Hoy en día está funcionando de forma continua.
2- No los tengo en la unidad, ¿Dónde puedo conseguir uno para completar la unidad principal?
3- filtros con señal de hongos, se puede limpiar, entiendo que lo mejor es cambiar, en ese caso donde puedo conseguir los filtros verde/azul y la tapa de cada filtro.

Quedo atento a comentarios.

As best I can tell, you are having problems with the fan in an Ilford 500 head.
I hope that some of our Spanish speaking members can help.

I had this head in the 90's, (sorry I don't understand what you wrote) If it is a fan issue, as Matt said, that is the reason why I got rid of it. It vibrated so much that it made images unsharp. The Ilford reps were useless (this was in Japan). They told me to stop the lens down to make the image sharper!

Vibraba tanto que hacía que las imágenes se vieran borrosas. Los representantes de Ilford fueron inútiles (esto fue en Japón). ¡Me dijeron que bajara la lente para que la imagen fuera más nítida!

Entiendo, si es tema de vibraciones es algo que molesta, en mi caso por suerete lograr que el ventilador no vibre, y ahora tengo que solucionar el tema del termino, cortar la operacion.

I guess I'll have to learn some Spanish I hope you can solve your issue!

Google translate (like Big Brother) is your friend:

point not working well
1- The fan does not turn off in 2 minutes, at first the fan turns off after the time in about 2 minutes. Today it is running continuously.
2- I don't have them in the unit, where can I get one to complete the main unit?
3- filters with a sign of fungus, it can be cleaned, I understand that it is best to change, in that case where can I get the green/blue filters and the cover of each filter.

I am attentive to comments.

Well,

Point 2 is enigmatic at least in the translation

At point 3: why can't you clean the filters?
Even if the fungi attacked the reflective coating (I assume dichroic filters) or the glass and unless the loss of coating is substantial, the filters should still work. They are not image-forming.

if they are dichroic, let's hope that the fungus does not continue to grow. / thank you

For what it's worth, the fan on the 500 head I used to have was always on. Never noticed any trouble because of it, apart from it being noisy.

reading, in the web and with participation of users they commented that the first models the ventilator worked continuously, in the newest models the ventilator cut after 2 minutes, in fact my equipment as soon as I bought it in 2 minutes it cut... I believe that my case, it stopped working the cut thermic. there is a way that is to add a new term, it is necessary to make adaptations.

going from memory, the fan time out is controlled by a chip on the board in the power supply. Last time I checked the chip was no longer available in the same package (DIP) but was available in newer formats. With adapter boards it could be made to work if you can't live with it running all the time. Not a trivial job but not hard with the right tools. If you need schematics let me know. There are at least three versions of that board.

thank you very much for your comments, I am already interested in solving the fan issue, not so much for the noise. As I spend 6 hours a day in the darkroom, my fear is that it will stop working. I attach a picture of the box that is above the lamps in the head of the enlarger.
