Food Timer only works for one tunze.?!?!

[ricka]

Roger,

I have a pair of 6200's and 7094 controlling them. It seems that the food timer only works for one of the 6200s. I tried swapping from connection but the problem follows one of the 6200s. The 6200s are brand new, I just got them from Marine Depot.

Does the 6200 respond to all the other controls except the foodtimer?

As far as I can tell it's only the food timer. I'll check tonight to see if the pulsing is working.

BTW, what is the difference between the little square wave, medium square wave and the big square wave?

[ricka]

I checked the flow and the controller doesn't seem to effect the tunze at all. It is going full blast all the time.

Should I sent it to you or have marine depot swap it? It is less than 30 days old.

I think the problem is with the cable. Try another cable but I have never seen this problem not be caused by a dirty connector or bad cable or a program you selected doesn't provide the features you want. Make sure their is no salt crud on anything and when you connect the controller to the pumps the pumps should be without power, plug them into the wall after connecting them to the controller. The waves are wider pulse intervals. 1.5-7 Sec. Marine Depot will not (or should not) take a return, it would have to come to me if this doesn't fix it.

I'll try swapping the actual cable to see if that fixes it.

Is there anything special about that cable or can I just fix/replace it with a straght through cable?

IME If the tunze is broken, MD will replace it. They replaced a Tunze Rock that got broken in shipping. They are very good about that kind of stuff.

The rock I can understand but because it is so rare that these things are actually broken I have tried to insist everything goes through me to try to minimize the grief of getting a box of items that are "defective" only to find it was user error or something overlooked. Seriously, if I get back 8 items maybe one has an actual defect and this costs both of us time and money. I turn things around very quickly and the causes in these cases can be so many that it is unlikely a new one would fix it, that would be something I haven't seen yet. I have seen everything from EMF interference to salty cables cause this sort of problem or a bad controller but not a bad pump or driver.

Anyway, the cable is a standard 5 pin DIN but ideally I would use an original cable, also be sure to observe the instructions I gave about the pumps being unplugged before connecting them.

 

[ricka]

Thanks Roger. I'll report back when I swap the cable.

Does MD stock that cable? I've wanted some longer ones anyways.

--Rick

 

[rvitko]

No, actually I am out of that cable but they are sending me some and worst case I'll give you one of my own. Fry's electronics is a good source for cables but 1.2m seems to be the standard for these cables but I have seen female to male cables.

If I can chime in, the pin configuration is the same as a standard MIDI cable so you might be able to hit up a musician buddy.

 

[ricka]

Cool. Thanks!

A buddy of mine says I can get MIDI cables at Radio Shack. I'm gonna pick up a couple on the way home and try it out.

[rvitko]

Good to know! I always just called it a 5 pin DIN cable.

 

[rach78978]

radio shack has 5 pin din, your all set!

 

[ricka]

I picked up a 3 pack (red, blue and yellow) for $10 and the problem is solved. I even have a spare now.

Thanks everybody!
